If you import rechargeable car vacuums, electric air dusters or turbo jet fans, you will probably see three battery documents during sourcing: UN38.3, MSDS or SDS, and IEC 62133-2. They are often sent together, which can make them look like three versions of the same battery certificate. They are not.
For international lithium battery shipping, UN38.3 is the transport-focused requirement of the three. An SDS or MSDS communicates battery hazards, handling and emergency information. IEC 62133-2 addresses the safety of portable rechargeable lithium cells and batteries during intended use and reasonably foreseeable misuse. IEC 62133-2 does not replace UN38.3, and an SDS does not prove that a battery has passed UN38.3 transport testing.
For Kinzir buyers, this distinction matters whether you are shipping a cordless car vacuum with its battery installed, a detachable battery turbo jet fan with the pack beside the product, or replacement batteries in a separate carton. The same battery can face a different shipping route depending on how it is packed.
UN38.3 vs MSDS vs IEC 62133 at a Glance
| Document or Standard | Main Role | International Shipping | Battery Safety Review | Typical User |
|---|---|---|---|---|
| UN38.3 | Lithium battery transport testing | Core transport requirement | Transport conditions | Shipper, carrier, importer |
| SDS / MSDS | Hazard and handling information | Commonly requested for logistics review | Hazard communication | Forwarder, warehouse, importer |
| IEC 62133-2 | Portable rechargeable lithium battery safety | Does not replace UN38.3 | Intended use and foreseeable misuse | Importer, product team, certification body |
The shortest way to remember the difference is:
UN38.3 = Can this battery type pass the prescribed transport tests?
SDS/MSDS = What is this battery, what hazards are associated with it, and how should it be handled?
IEC 62133-2 = Does this portable rechargeable battery meet the applicable safety tests for use and foreseeable misuse?
IEC identifies the current consolidated publication as IEC 62133-2:2017+A1:2021.
Start With the Shipping Configuration
Before asking your supplier which PDF files are available, establish how the battery will travel.
That determines whether the shipment is treated as a battery by itself, a battery packed with equipment, or a battery contained in equipment.
For lithium-ion batteries used in cordless cleaning products, the three common air-shipping situations are UN3480 and two forms of UN3481. IATA’s 2026 guidance assigns PI 965 to lithium-ion batteries shipped by themselves, PI 966 to lithium-ion batteries packed with equipment, and PI 967 to lithium-ion batteries contained in equipment.
What Is UN3480?
UN3480, Lithium ion batteries applies when lithium-ion batteries are shipped by themselves.
A practical Kinzir example would be:
A distributor orders 500 spare detachable battery packs for its turbo jet fans. The shipment contains batteries but no turbo jet fans.
For air transport, UN3480 is handled under Packing Instruction 965. IATA states that UN3480 lithium-ion cells and batteries shipped by themselves are forbidden as cargo on passenger aircraft under the normal provisions and must be handled under the applicable cargo-aircraft rules. IATA also limits UN3480 shipments to no more than 30% state of charge unless the required State approvals are obtained.
What Is UN3481, Batteries Packed With Equipment?
This situation applies when the rechargeable battery and the product it operates are in the same package, but the battery is not installed in the product.
Example:
A detachable battery is packed beside a turbo jet fan in the same retail box.
For air transport, this is normally handled under UN3481, Lithium ion batteries packed with equipment, PI 966.
This is highly relevant to OEM detachable battery turbo jet fans and OEM detachable battery electric air dusters, where the battery pack may be removable from the appliance.
What Is UN3481, Batteries Contained in Equipment?
Here, the battery is installed inside the appliance during shipment.
Examples include:
- A cordless car vacuum shipped with its rechargeable battery installed
- An air duster shipped with its integrated battery inside the housing
- A detachable battery turbo jet fan shipped with the battery fitted to the fan
For air transport, this normally falls under UN3481, Lithium ion batteries contained in equipment, PI 967.
Packed With vs Contained In
This distinction can look minor in a product-development meeting, but it can change the air-shipping conditions.
| Shipment | Typical Classification | Air Packing Instruction |
|---|---|---|
| Battery shipped alone | UN3480 | PI 965 |
| Battery beside the appliance | UN3481 | PI 966 |
| Battery installed in the appliance | UN3481 | PI 967 |
A detachable pack sitting beside a product in a carton is not automatically treated the same way as the same pack installed in that product.
UN38.3 Lithium Battery Transport Testing
UN38.3 refers to Part III, subsection 38.3 of the United Nations Manual of Tests and Criteria.
The UN Manual supplies test methods and criteria used in dangerous-goods classification, including requirements for lithium cells and batteries. The current UNECE Rev. 8 materials contain subsection 38.3 and later amendments addressing lithium battery testing.
A battery type that will enter normal international transport should not be selected merely by checking capacity, voltage and price. Transport qualification needs to be part of the battery approval process.
The Eight UN38.3 Test Types
UN38.3 includes eight test designations commonly referred to as T.1 through T.8:
| Test | Main Transport Condition Assessed |
|---|---|
| T.1 | Altitude simulation |
| T.2 | Thermal testing |
| T.3 | Vibration |
| T.4 | Shock |
| T.5 | External short circuit |
| T.6 | Impact / crush, as applicable |
| T.7 | Overcharge |
| T.8 | Forced discharge |
These tests are intended to examine lithium cells and batteries under conditions relevant to transport, rather than act as a general household-appliance safety program. The detailed procedures and applicability rules are set by the UN Manual of Tests and Criteria.
That difference matters. A battery can have strong runtime and excellent everyday performance and still need the correct transport qualification before international shipment.
UN38.3 Test Report vs UN38.3 Test Summary
Importers often ask suppliers:
“Can you send me the UN38.3 certificate?”
That wording can hide two different documents: a test report and a test summary.
What Is a UN38.3 Test Report?
The detailed test report records the laboratory testing carried out on the applicable battery type. It can contain test conditions, battery identification, test methods and results.
Importers may request the report during supplier approval, especially for custom battery packs or when the forwarder needs extra evidence.
What Is a UN38.3 Test Summary?
The test summary is the defined summary that manufacturers and subsequent distributors must make available for applicable lithium cells and batteries.
IATA’s 2026 guidance says the test summary must be made available on request and can be supplied electronically, such as through a website, QR code or URL. IATA does not support requiring a paper copy to travel with every shipment.
The summary contains identifying information that lets the requester connect the document to the tested battery, including items such as test-report identification, test date, battery or product description, test-house information and relevant battery data.
For an importer, this is far more useful than a supplier writing:
“UN38.3 passed.”
You need to be able to determine which battery passed.
Is UN38.3 a Certificate?
It is better to avoid treating UN38.3 like a conventional certification mark issued under one global certificate scheme.
The practical sourcing question is:
Can the supplier provide a valid UN38.3 test summary, and supporting test evidence where requested, for the exact battery type used in my product?
IATA states that a test summary remains valid as long as the battery type has not been changed in a way requiring retesting.
Matching UN38.3 Documents to the Actual Battery
A real test summary can still be the wrong document for your product.
Before shipment, compare the paperwork against the production battery.
Check the battery model, voltage, Wh rating, physical description, pack configuration and other identifying information.
Take a simple example.
Your approved turbo jet fan uses an 18.5V 5S2P battery pack. Your supplier sends you a test summary covering a small 7.4V battery used in another air duster.
Both are rechargeable lithium-ion batteries, but they are not the same battery type.
If your product uses a custom 5S2P battery pack, the transport documents should be checked against that actual pack rather than an unrelated battery from the factory’s document library.
For OEM buyers, battery approval should record at least:
battery model + nominal voltage + Ah + Wh + cell configuration + UN38.3 reference
This is particularly useful when one supplier offers several battery choices for the same housing.
SDS and MSDS for Lithium Batteries
MSDS means Material Safety Data Sheet.
SDS means Safety Data Sheet.
SDS is the current terminology used in modern hazard-communication systems, though “MSDS” remains common language in battery sourcing and freight discussions.
The purpose of an SDS is hazard communication. OSHA describes its Hazard Communication Standard as a system for communicating information about hazards to workers and treats SDS documentation within that hazard-communication framework.
A lithium battery SDS can include sections covering:
- Product and company identification
- Hazard information
- Composition
- First-aid measures
- Fire-fighting measures
- Accidental release
- Handling and storage
- Stability and reactivity
- Disposal
- Transport information
Does MSDS Replace UN38.3?
No.
This is one of the most common document mistakes in lithium battery sourcing.
An SDS may contain a transport section listing information such as the battery chemistry or relevant UN classification. That does not demonstrate that the battery type passed the tests in UN subsection 38.3.
Think of the two documents this way:
UN38.3 provides transport-test evidence for the battery type.
SDS/MSDS communicates hazards and handling information.
They can both be useful to the logistics chain, but they answer different questions.
Is an SDS Mandatory for Every International Lithium Battery Shipment?
Do not use a blanket statement such as “every lithium battery shipment legally requires an MSDS.”
SDS duties can arise from hazard-communication rules, and freight forwarders, warehouses, carriers or customers often request an SDS as part of shipment review. The exact document set depends on the legal jurisdiction, transport mode, carrier and shipment configuration. OSHA’s lithium-ion battery interpretations, for example, address SDS requirements through its workplace hazard-communication framework.
For international sourcing, the safer practical rule is:
Keep a current battery SDS available, but do not mistake it for UN38.3 transport qualification.
IEC 62133-2 for Portable Rechargeable Lithium Batteries
IEC 62133-2 has another purpose.
IEC describes IEC 62133-2:2017+A1:2021 as setting requirements and tests for the safe operation of portable sealed secondary lithium cells and batteries containing non-acid electrolyte under intended use and reasonably foreseeable misuse.
For Kinzir-type products, that can make IEC 62133-2 relevant during battery sourcing, product safety review or certification programs involving portable rechargeable batteries.
Does IEC 62133-2 Replace UN38.3?
No.
UN38.3 is transport-focused.
IEC 62133-2 is portable rechargeable battery safety-focused.
A supplier providing an IEC 62133-2 test report has not, by that fact alone, demonstrated compliance with UN38.3 transport testing.
Does UN38.3 Replace IEC 62133-2?
No.
Passing transport tests does not demonstrate compliance with every portable battery safety requirement used in product certification or national market-access programs.
The importer needs to determine which standards apply to the final product and destination market.
UN38.3 vs SDS/MSDS vs IEC 62133-2 Detailed Comparison
| Comparison | UN38.3 | SDS / MSDS | IEC 62133-2 |
|---|---|---|---|
| Primary purpose | Transport qualification | Hazard communication | Portable rechargeable battery safety |
| Laboratory testing | Yes | Not a transport test program | Yes |
| Main context | Air, sea and other DG transport frameworks | Handling, storage, emergency and workplace review | Product and battery safety |
| Does it prove UN38.3? | Yes, when applicable test evidence covers the battery | No | No |
| Can it replace SDS? | No | N/A | No |
| Can it replace IEC 62133-2? | No | No | N/A |
| Commonly reviewed by freight forwarder | Yes | Often | Less common |
| Commonly reviewed by importer/product team | Yes | Yes | Yes, where applicable |
| Battery identity must match | Yes | Yes | Yes |
| Useful after an OEM battery change | Must be reviewed | Should be updated/reviewed | Must be reviewed where applicable |
The safest buying approach is not to ask whether a supplier has “battery certificates.”
Ask which exact battery model each document covers.
2026 Lithium Battery Air Shipping Changes
Battery transport rules change regularly, which is why old sourcing checklists can become unreliable.
IATA’s 67th Edition Dangerous Goods Regulations apply from 1 January 2026.
One of the most relevant changes for detachable-battery products concerns state of charge.
UN3480 Batteries Shipped Alone
Lithium-ion cells and batteries shipped by themselves as UN3480 must be offered for air transport at a state of charge no greater than 30% of rated capacity, unless shipment above that level follows the applicable approval route. UN3480 battery-only packages are not permitted as cargo on passenger aircraft under the normal provisions.
This affects spare battery shipments for removable-battery car vacuums and turbo jet fans.
PI 966 Batteries Packed With Equipment
This is the change many private-label brands should pay close attention to.
From 1 January 2026, IATA’s PI 966 Section I requires lithium-ion cells and batteries packed with equipment to be offered at no more than 30% SoC. For PI 966 Section II, lithium-ion cells and batteries above 2.7Wh are likewise limited to 30% SoC unless the applicable approval conditions are used.
This can affect a removable battery packed beside:
- A turbo jet fan
- An electric air duster
- A cordless car vacuum
If your retail packaging strategy keeps the detachable pack outside the appliance, discuss the shipment classification with the dangerous-goods team before mass production.
PI 967 Batteries Contained in Equipment
IATA’s 2026 guidance takes a different approach when lithium-ion batteries are contained in equipment.
For PI 967, IATA strongly recommends offering the batteries at no more than 30% SoC or with indicated battery capacity no greater than 25%, but it states that the reduced SoC is not universally mandatory for these items under the cited guidance.
That difference between PI 966 and PI 967 is one reason buyers should not treat “battery in the box” as a sufficient shipping description.
The 100Wh Threshold
Watt-hours matter for much more than runtime.
For lithium-ion battery transport, IATA distinguishes cells at or below 20Wh and batteries at or below 100Wh from higher-energy cells and batteries in its packing framework.
The calculation is:
Wh = nominal voltage × Ah
A practical example from a 5S2P battery system shows how quickly the threshold can be crossed.
| Battery | Calculation | Energy |
|---|---|---|
| 18.5V, 4Ah | 18.5 × 4 | 74Wh |
| 18.5V, 5Ah | 18.5 × 5 | 92.5Wh |
| 18.5V, 6Ah | 18.5 × 6 | 111Wh |
| 18.5V, 8Ah | 18.5 × 8 | 148Wh |
Changing from a 5Ah pack to a 6Ah pack moves this example from below 100Wh to above it.
That battery upgrade may look small from a marketing perspective, yet it can affect air-shipping sections, packaging and carrier acceptance.
This is one reason Kinzir’s 18650 vs 21700 battery guide recommends comparing Wh together with voltage and Ah rather than looking at mAh alone.
Packaging, Marks, Labels and Shipping Documents
Having a UN38.3 test summary does not complete a lithium battery shipment.
The battery still needs to be packed, marked, labelled and documented according to the applicable transport provisions.
IATA’s Battery Shipping Regulations cover packaging, marking, labelling and shipment handling, and the detailed requirements differ by UN number, Wh rating, packing instruction, section, quantity and aircraft type.
A shipment may need items such as:
- Lithium battery mark
- Applicable UN number
- Class 9 lithium battery hazard label
- Cargo Aircraft Only label
- Dangerous Goods Declaration
- Correct packaging
- Short-circuit protection
- Protection against unintended activation
The exact combination cannot be determined from the words “lithium battery” alone.
For example, IATA’s 2026 guidance shows different package limits and marking routes for UN3480 PI 965, UN3481 PI 966 and UN3481 PI 967.
Dangerous Goods Declaration
Some lithium battery consignments require a Shipper’s Declaration for Dangerous Goods, while other shipments may operate under provisions that do not require the same declaration.
IATA publishes current 2026 dangerous-goods documentation resources alongside the 67th Edition DGR.
The importer should ask:
Who will classify, pack, mark and declare the shipment?
Do not assume the freight forwarder will correct a poorly prepared battery shipment after collection.
Responsibilities Across the Supply Chain
Battery shipping usually involves several companies:
Battery cell maker → battery pack assembler → finished-product manufacturer → exporter/shipper → freight forwarder → airline or shipping line → importer
Each party can hold different information.
The battery supplier may control the cell and pack technical data.
The product manufacturer may control how the battery is installed or packed.
The shipper needs the correct classification and shipment documentation.
The forwarder and carrier review acceptance against their transport rules.
IATA offers dedicated dangerous-goods training for personnel responsible for preparing battery consignments, covering classification, packing, marking, labelling and documentation.
For an OEM buyer, decide who is responsible for dangerous-goods preparation before the production shipment reaches the warehouse.
Air Freight vs Sea Freight
Lithium battery rules do not stop at air cargo.
Air Freight
For air shipping in 2026, IATA DGR provides the commercial airline framework based on international aviation dangerous-goods requirements.
For rechargeable cordless cleaning products, buyers commonly encounter:
- UN3480
- UN3481
- PI 965
- PI 966
- PI 967
- Wh thresholds
- SoC restrictions
- Package limits
- Battery marks and hazard labels
Sea Freight
International maritime dangerous-goods transport operates under the IMDG Code rather than the IATA DGR.
The IMO states that the IMDG Code 2024 Edition, including Amendment 42-24, became mandatory on 1 January 2026. The Code covers packaged dangerous goods and includes requirements for packing, container handling, stowage and segregation.
UN38.3 remains relevant to lithium battery transport qualification, but air packing instructions such as PI 965, PI 966 and PI 967 should not simply be copied into a sea-freight shipment.
Your freight forwarder should review the actual shipment against the current IMDG Code.
Courier Services
Express carriers can apply their own acceptance rules on top of the regulations.
Before planning courier shipment, provide the carrier with:
- UN classification
- Battery Wh
- Battery quantity
- Installed, packed-with or battery-only status
- Destination
- Package configuration
A legal transport route does not guarantee that every courier service or lane will accept it.
Spare Detachable Batteries Need a Separate Shipping Plan
Removable batteries solve one product problem and can create a different logistics question.
Suppose an importer sells the Kinzir AD80 removable battery turbo jet fan with its battery fitted to the product. Kinzir’s current product page describes the AD80 as a user-removable battery model.
The original product shipment can be assessed as batteries contained in equipment when the battery is installed.
Months later, the importer needs to send a customer a spare battery with no fan.
That replacement pack is now a battery shipped by itself and may fall under UN3480 rather than UN3481.
This difference should be planned before launching a removable-battery product line.
The same issue applies to OEM removable battery car vacuums such as Kinzir’s VC16R and VC26R platforms.
Damaged, Defective and Recalled Lithium Batteries
After-sales shipments need extra care.
A new spare battery and a swollen, damaged or safety-recalled battery should not be treated as the same consignment.
IATA’s lithium battery rules include restrictions and prohibitions for batteries identified as defective for safety reasons or damaged in a way that could create dangerous heat, fire or short circuit.
Examples that need specialist review include:
- Swollen battery packs
- Fire-damaged packs
- Crushed batteries
- Batteries showing internal damage
- Batteries subject to a safety recall
Do not ask a customer to place a damaged battery into the same ordinary courier channel used for a new replacement pack.
For OEM brands building a removable-battery after-sales program, create separate procedures for new spare batteries and damaged returns.
Prototype and Low-Production OEM Batteries
Battery documents can become a bottleneck during OEM sampling.
A brand may change from:
- 18650 to 21700 cells
- 2S to 5S2P
- Built-in to detachable battery
- One battery supplier to another
- Lower capacity to higher capacity
The new prototype may not have the same transport status as the old production battery.
IATA and the UN framework contain special provisions for certain prototype or low-production batteries, subject to defined approval conditions. These routes should be handled by a dangerous-goods specialist rather than treated as a shortcut around normal testing.
If an OEM prototype battery does not yet have normal UN38.3 qualification, ask the forwarder and battery specialist before the sample is packed for air shipment.
Battery Changes and Document Change Control
This is one of the most important checks for private-label sourcing.
A supplier may have excellent paperwork for its standard model. Your custom version can change the battery.
Examples include:
- 18650 changed to 21700
- Different cell manufacturer
- Different cell model
- Higher battery capacity
- New series/parallel configuration
- Different BMS
- New battery housing
- Integrated pack changed to detachable pack
IATA states that the test summary remains valid when the cell or battery type has not been changed in a way requiring retesting. That means battery design changes should trigger a document review rather than an assumption that the old report still applies.
If your project moves from a standard battery to a custom 5S2P battery pack, put transport-document review into the engineering change process.
International Shipping Examples for Kinzir Products
The following examples show how product packaging can change the likely air-shipping route.
| Product Shipment | Typical Classification | Typical IATA PI |
|---|---|---|
| Cordless car vacuum with battery installed | UN3481 contained in equipment | PI 967 |
| Electric air duster with battery installed | UN3481 contained in equipment | PI 967 |
| Turbo jet fan with detachable battery installed | UN3481 contained in equipment | PI 967 |
| Turbo jet fan with battery beside product | UN3481 packed with equipment | PI 966 |
| Replacement battery shipped without product | UN3480 | PI 965 |
The table is a starting point, not a shipment declaration. Final classification depends on the real battery, product, packaging and shipment.
For buyers developing detachable-battery products, Kinzir’s turbo jet fan removable battery upgrade guide explains how battery architecture changes can affect terminals, BMS, housing, labels and export documentation.
EU Battery Regulation and International Shipping
UN38.3 and the EU Battery Regulation deal with different stages.
UN38.3 deals with transport testing.
Regulation (EU) 2023/1542 deals with batteries placed on the EU market and their wider lifecycle, including conformity, information, waste responsibilities and product-design requirements.
One does not replace the other.
A rechargeable car vacuum shipped successfully from China can still need separate EU battery compliance work before sale.
February 2027 Removable and Replaceable Battery Rules
Article 11 of Regulation (EU) 2023/1542 applies from 18 February 2027.
The European Commission’s updated July 2026 guidance says that the Article 11(1) obligation for portable batteries applies to the entire battery rather than individual internal cells. The guidance describes removal and replacement of the complete battery without damage to the battery or device.
This is directly relevant to Kinzir’s EU Battery Regulation 2027 product program and its removable-battery car vacuums, air dusters and turbo jet fans.
The same Commission guidance states that applicable portable batteries must be available as spare parts for at least five years after the last unit of the equipment model is placed on the market, under the conditions in Article 11(7).
This creates an important link between EU product design and international logistics:
If you plan to offer spare replacement batteries for five years, you also need a workable shipping route for those battery-only after-sales consignments.
QR Code From February 2027
Regulation (EU) 2023/1542 states that from 18 February 2027 all batteries must carry the Article 13 QR code, with the linked information depending on battery type. For batteries outside the passport categories, the QR code links to applicable Article 13 information, the declaration of conformity and specified waste-battery information.
A QR code is an EU market-information requirement. It is not a replacement for the UN38.3 test summary or transport documentation.
Latest July 2026 EU Guidance
On 14 July 2026, the European Commission published updated guidelines on removability and replaceability of portable and LMT batteries. It also adopted a delegated act adding six categories to the list of products eligible for specific removability derogations, including certain wearable devices, electric toys and equipment covered by ATEX rules. The Commission stated that the delegated act was subject to European Parliament and Council scrutiny before entry into force.
Cordless car vacuums, electric air dusters and turbo jet fans should not be assumed to fall within those new categories.
Battery Due Diligence Date Moved to 2027
Older battery-compliance articles may still show an outdated 2025 due-diligence date.
Regulation (EU) 2025/1561 amended Article 48 and moved the battery due-diligence application date from 18 August 2025 to 18 August 2027.
For importers, the practical lesson is simple: use current EU sources rather than relying on a battery compliance checklist written before the amendment.
EU WEEE Is Another Separate Layer
Cordless car vacuums, air dusters and turbo jet fans are electrical products, so battery compliance does not cover every end-of-life duty for the appliance itself.
Kinzir’s EU WEEE Requirements guide covers WEEE producer registration, marking, reporting and recycling responsibilities separately.
Importer Pre-Shipment Battery Document Checklist
Before approving an international shipment, collect and verify the battery information as one package rather than as unrelated PDFs:
- Battery identity: manufacturer, pack model, cell model, chemistry, cell count, pack configuration, nominal voltage, Ah and Wh.
- Transport file: UN38.3 test summary, supporting test report when requested, current SDS/MSDS when applicable or requested, correct UN classification, packing instruction and state-of-charge confirmation.
- Shipment preparation: packaging, marks, labels, package limits and Dangerous Goods Declaration where the applicable provisions require it.
- Product safety file: IEC 62133-2 documentation where relevant to the market or certification program, BMS specification, charger data and battery protection information.
- EU file: Regulation (EU) 2023/1542 conformity review, battery marking, QR-code planning, Article 11 removability review, spare-battery plan and applicable EPR or due-diligence obligations.
The value of this checklist is not the number of documents.
It is whether every document describes the battery you are actually buying and shipping.
Supplier Document Verification
When a supplier sends a folder named “Battery Certificates,” do not approve it from the filenames.
Check:
1. Battery model
Does the test summary identify the pack used in your SKU?
2. Voltage and Wh
Do they match the production specification?
3. Physical battery
Does the construction described in the file correspond with the pack in your approved sample?
4. Test-report reference
Is the laboratory and report identification present in the test summary?
5. OEM changes
Has the cell, BMS, configuration or capacity changed since testing?
6. Shipment configuration
Will the pack ship alone, beside the appliance or installed inside it?
7. State of charge
Does the planned air shipment meet the current 2026 SoC provisions?
8. Transport mode
Is the shipment being prepared for air, sea or another mode under the correct current rules?
A supplier can possess genuine battery documents and still send the wrong file for a custom model.
Common Battery Shipping Document Mistakes
Mistake 1: Treating MSDS as UN38.3 evidence
SDS/MSDS communicates hazards. It does not demonstrate completion of the UN38.3 transport tests.
Mistake 2: Treating IEC 62133-2 as a transport certificate
IEC 62133-2 addresses portable rechargeable lithium battery safety during use and foreseeable misuse, not the UN transport-test program.
Mistake 3: Asking only for a “UN38.3 certificate”
Ask for the test summary and confirm that it covers the actual battery type.
Mistake 4: Accepting paperwork for another battery
A report for another capacity, voltage or pack architecture should not be accepted without checking whether it covers the production battery.
Mistake 5: Ignoring Wh
A capacity change can move a lithium-ion battery above 100Wh and change its air-transport treatment.
Mistake 6: Confusing UN3480 and UN3481
Battery-only and equipment-related shipments follow different transport provisions.
Mistake 7: Confusing PI 966 with PI 967
A battery packed beside equipment is different from a battery contained in equipment.
Mistake 8: Missing the 2026 PI 966 SoC change
From 1 January 2026, PI 966 shipments are subject to the new 30% SoC rules described by IATA.
Mistake 9: Shipping spare packs as though they were contained in equipment
A replacement battery shipped without the appliance can fall under UN3480.
Mistake 10: Shipping a damaged battery through an ordinary parcel route
Damaged and safety-defective lithium batteries require separate review under the applicable dangerous-goods rules.
Mistake 11: Changing battery cells without reviewing transport documents
Cell, pack or BMS changes can affect whether existing testing remains applicable.
Mistake 12: Treating EU Battery Regulation compliance as transport approval
EU market requirements and international dangerous-goods transport requirements are separate regulatory layers.
UN38.3 vs MSDS vs IEC 62133 FAQs
Is UN38.3 mandatory for lithium-ion batteries?
Lithium cells and batteries offered for normal dangerous-goods transport need to meet the applicable UN 38.3 requirements, subject to the provisions and limited exceptions in the transport rules. IATA’s 2026 guidance bases lithium-ion transport classification on compliance with UN Manual of Tests and Criteria subsection 38.3.
Is UN38.3 a certificate?
It is better described as a UN transport-test requirement. Importers should request the applicable test summary and supporting test evidence rather than rely on the word “certificate.”
What is the difference between a UN38.3 test report and test summary?
The report contains detailed test evidence. The test summary provides the required identifying and test information in a shorter format that manufacturers and subsequent distributors must make available on request.
Who should provide the UN38.3 test summary?
Manufacturers and subsequent distributors of applicable lithium cells and batteries must make the test summary available. It can be supplied electronically and does not have to travel as a paper document in every shipment.
Does MSDS replace UN38.3?
No. An SDS/MSDS communicates hazard and handling information. It is not evidence that the battery has passed UN38.3 transport testing.
Is an MSDS mandatory for every lithium battery shipment?
Do not apply one universal rule to every route and jurisdiction. SDS requirements can arise from hazard-communication laws, and logistics companies commonly request them. Shipment acceptance still depends on the applicable dangerous-goods rules and carrier requirements.
What is the difference between SDS and MSDS?
SDS means Safety Data Sheet. MSDS means Material Safety Data Sheet, an older term still widely used in sourcing and logistics.
Does IEC 62133-2 replace UN38.3?
No. IEC 62133-2 addresses safety requirements and testing for portable rechargeable lithium cells and batteries. UN38.3 addresses lithium battery transport testing.
What is IEC 62133-2 used for?
IEC 62133-2:2017+A1:2021 covers safe operation of portable sealed secondary lithium cells and batteries under intended use and reasonably foreseeable misuse. It can be relevant to battery safety evaluation and product-certification programs.
What is UN3480?
UN3480 is the classification used for lithium-ion batteries shipped by themselves. For air transport, it is associated with PI 965.
What is UN3481?
UN3481 covers lithium-ion batteries packed with equipment or contained in equipment. Air shipment normally uses PI 966 for packed-with and PI 967 for contained-in configurations.
What is the difference between PI 965, PI 966 and PI 967?
PI 965 applies to lithium-ion batteries shipped alone. PI 966 applies to batteries packed with equipment. PI 967 applies to batteries contained in equipment.
Is a removable battery packed with or contained in equipment?
It depends on how it is physically shipped. If it is installed in the product, it can be contained in equipment. If it is packed beside the product rather than installed, it can fall under packed-with-equipment provisions.
What documents are needed to ship a cordless car vacuum internationally?
The exact set depends on battery Wh, how the battery is packed, transport mode and destination. An importer should review UN38.3 documentation, battery identification, shipping classification, packaging and marks, plus an SDS where applicable or requested. IEC 62133-2 may be relevant to product safety but does not replace the transport file.
What documents are needed to ship a turbo jet fan internationally?
Start with the exact battery pack, Wh rating and whether it is installed, packed beside the fan or shipped separately. From there, determine the applicable UN classification, transport instructions and supporting battery documents.
How are spare removable batteries shipped?
A spare lithium-ion pack shipped without the appliance is typically treated as a battery by itself, UN3480 for the lithium-ion scenario covered here, rather than a battery contained in equipment.
What is the 100Wh lithium battery threshold?
IATA distinguishes lithium-ion batteries at or below 100Wh from batteries above 100Wh in its air-shipping framework. The threshold can affect packing section and package requirements.
What changed for lithium battery air shipping in 2026?
A key change is the 30% state-of-charge restriction for lithium-ion batteries packed with equipment under PI 966 from 1 January 2026. IATA’s 67th Edition DGR applies in 2026.
Does a PI 966 battery need to be below 30% charge in 2026?
For PI 966 Section I, yes, unless the applicable State approvals are used. Section II batteries above 2.7Wh are likewise subject to the 30% rule under the 2026 guidance.
Does a PI 967 battery contained in equipment need to be below 30%?
IATA’s 2026 guidance strongly recommends reduced SoC for lithium-ion batteries contained in equipment, but states that the reduced SoC is not universally mandatory for those items under the cited provision.
Can a battery above 100Wh be shipped internationally?
Yes, in many cases, but it can fall under more stringent transport provisions. The exact route depends on transport mode, battery classification, packing method and carrier acceptance. IATA uses 100Wh as an important threshold in its lithium-ion air-transport framework.
Can damaged lithium batteries be shipped by air?
Damaged or safety-defective batteries can be prohibited from normal air transport. They require specialist assessment under the current dangerous-goods rules rather than ordinary new-battery procedures.
Does changing battery capacity require a new UN38.3 review?
It requires a review of whether the existing testing still covers the revised battery type. IATA states that test-summary validity depends on the battery type not being changed in a way that requires retesting.
Does EU Battery Regulation 2023/1542 replace UN38.3?
No. Regulation (EU) 2023/1542 deals with placing batteries on the EU market and their lifecycle obligations. UN38.3 is part of the international dangerous-goods transport framework.
What changes for removable batteries in the EU in 2027?
Article 11 applies from 18 February 2027 and sets removability and replaceability requirements for applicable portable batteries incorporated into products. The Commission’s July 2026 guidance confirms that the portable-battery obligation concerns the entire battery rather than its individual internal cells. All batteries are also scheduled to carry the Article 13 QR code from 18 February 2027.
What should I request from a lithium battery supplier?
At minimum, ask for the exact battery specification, Wh rating, UN38.3 test summary, supporting transport test evidence where needed, SDS/MSDS where applicable or requested, and IEC 62133-2 evidence when it is relevant to your product-safety or market-access program.
International Lithium Battery Shipping With Kinzir
For a private-label car vacuum, electric air duster or turbo jet fan, battery documentation should be confirmed before mass production, not after the finished cartons arrive at the freight warehouse.
Tell the manufacturer:
- Which countries you will import into
- Whether the product will travel by air or sea
- Whether the battery will be installed or packed separately
- Whether spare batteries will be included
- Whether replacement packs will be sold later
- Your required battery capacity and Wh
- Your EU market plan
This makes it possible to review the battery architecture together with packaging and shipping requirements.
Kinzir supplies cordless cleaning products with built-in and removable battery options and supports private-label buyers through product development and export preparation. Buyers preparing for Europe can pair the shipping review in this article with Kinzir’s EU Battery Regulation 2027 guide and EU WEEE Requirements guide.
The point is not to collect the largest folder of certificates.
The point is to have the right battery, the right documents and the right shipping classification for the product that is actually leaving the factory.
