Shipping Battery Appliances: UN 38.3 and Air Rules
Updated 2026-11-09
A battery-powered appliance ships under dangerous goods rules, and the rules differ by mode. Air freight follows the IATA Dangerous Goods Regulations, sea freight follows the IMDG Code, and both build on the UN Model Regulations. Before booking you need a UN 38.3 test summary, a safety data sheet, and a decision on whether the battery is installed in the device, packed with it, or shipped alone.
Shipping Battery Appliances: UN 38.3 and Air Rules
Three categories in this trade carry a battery: portable blenders, rechargeable hand warmers, and some heated lunch boxes. Each one turns an ordinary appliance shipment into a dangerous goods shipment, and the paperwork starts before the goods are packed.
This page explains what the rules are built on, what documents you need, and the design decisions that make shipping simpler.
The rule stack
| Level | Instrument | What it does |
|---|---|---|
| Global model | UN Model Regulations, with the Manual of Tests and Criteria | Defines classification, test requirements and packing concepts |
| Air | IATA Dangerous Goods Regulations | Turns the model regulations into airline requirements and packing instructions |
| Sea | IMDG Code, under SOLAS chapter VII | Sets packing, stowage, segregation and documentation for sea transport |
| National | Transport regulations in each country | Adds national requirements and enforcement |
Every mode builds on the same foundation, which is why a battery type that has passed the UN tests is accepted more easily everywhere. The test summary is the document that proves it.
UN 38.3 in one paragraph
Section 38.3 of the UN Manual of Tests and Criteria sets out the tests a lithium cell or battery type must pass before transport. The tests cover altitude simulation, thermal cycling, vibration, shock, external short circuit, impact or crush, overcharge and forced discharge. A test summary records the battery type, the tests and the results.
Two practical consequences:
- It is a type test, not a unit test. The summary covers a battery design, not each battery produced. If the cell or the protection circuit changes materially, the type may need retesting.
- The summary is a document you must be able to produce. Airlines and forwarders ask for it, and a supplier who cannot send it is a supplier whose battery you cannot ship by air.
What each mode asks for
| Mode | Regulation | Documents usually required | Who arranges |
|---|---|---|---|
| Air | IATA DGR | UN 38.3 test summary, safety data sheet, shipper’s declaration where applicable, approved packing | Shipper or a dangerous goods agent |
| Sea | IMDG Code | Classification, dangerous goods declaration, packing certificate, stowage away from heat sources | Shipper and forwarder |
| Road (destination) | National rules based on the UN Model Regulations | Transport document, packaging, driver instructions where required | Importer or haulier |
The air route is the stricter one in practice, because airlines screen cargo and can refuse it at the last moment. Sea is more forgiving on paperwork but slower and subject to carrier acceptance rules of its own.
Installed, packed with, or alone
This is the single most useful distinction for an appliance buyer, because it decides how much documentation and packaging work is involved.
| Configuration | What it means | Effect |
|---|---|---|
| Contained in equipment | Battery inside the appliance, appliance is the package | Simplest for appliances; terminals protected by the product |
| Packed with equipment | Battery in the same box, separate from the appliance | Needs individual protection and separate declaration |
| Shipped alone | Batteries without equipment | Most restrictive; highest documentation burden |
Design advice that follows: keep the battery inside the product for shipment, and do not ship spare batteries unless a customer requires them. Every spare battery you add is a document layer and a refusal risk.
Watt-hour limits and why they matter commercially
Battery capacity is expressed in watt-hours for lithium ion. Consumer appliances typically sit in the small battery band, while larger packs move into stricter provisions. The limits are set in the regulations, not by the carrier, but carriers apply their own acceptance rules on top.
Two commercial consequences:
- A bigger battery can change the shipping route, not just the price. If a design upgrade pushes the pack into a stricter band, the freight plan may need to change with it.
- The appliance’s retail claims depend on the battery. A hand warmer sold as a power bank carries a capacity claim, and that claim is the same number that decides its transport category. Marketing and logistics should read the same specification.
For passenger travel, the FAA sets limits for what individuals may carry: lithium ion batteries are limited per battery, and spare batteries must travel in cabin baggage with terminals protected. That is relevant to your listing text, because customers ask.
Design decisions that simplify shipping
| Decision | Simpler option | Why |
|---|---|---|
| Battery location | Installed inside the housing, not user-removable | Fewer loose batteries, fewer documents |
| State of charge at shipment | Follow the limit for the packing instruction in use | Reduces risk and satisfies carrier requirements |
| Terminal protection | Integrated connector, no exposed contacts | Removes a packaging step |
| Packaging | Battery retained so it cannot move in transit | Prevents damage that turns into a reportable incident |
| Spare parts | Ship separately, or not at all | Avoids mixed-cargo complications |
State of charge deserves a note. The air regulations limit the charge level for batteries shipped on their own, and the limit has been 30% in recent editions of the packing instruction. Confirm the current figure with your dangerous goods provider, because it is revised.
What to ask a supplier before you book
- Which battery type and capacity, in watt-hours?
- Do you have the UN 38.3 test summary for that type, and does it match the battery in my product?
- Is there a safety data sheet for the battery?
- Is the battery installed, packed with, or separate?
- What state of charge will the units be at when packed?
- Which markets has this battery configuration shipped to before, and by which mode?
Question six is the practical one. A supplier who has shipped the product by sea to Europe and by air to the United States has already solved problems you are about to discover.
What to tell the customer
Battery rules do not stop at the port. Customers ask whether they can take the product on a flight, and the answer belongs in your listing, not only in your inbox.
Three sentences cover most of it: the battery capacity in watt-hours, the fact that spare batteries must travel in cabin baggage with terminals protected, and an instruction to check with the airline because limits vary. Do not promise that the product is accepted on board. Airlines apply their own rules on top of the regulations, and a promise you cannot keep becomes a return.
The same discipline applies to marketplace listings. A battery product needs its capacity and transport information stated clearly, and a listing that omits it attracts exactly the questions that turn into disputes.
Where this fits the rest of the order
Battery status changes the freight booking, so it belongs in the freight decision before rates are compared. It changes the document set described in customs documents. And it changes the inspection plan, because a battery that is not retained in its compartment is a damage risk in transit; the packing checks are in pre-shipment inspection.

Frequently asked questions
What battery documents such as UN 38.3 and MSDS do portable appliances need?
A UN 38.3 test summary for the cell or battery type, a safety data sheet for the battery, and a declaration of dangerous goods if the mode and packing instruction require one. The test summary names the battery type and the tests passed; the safety data sheet describes the hazards. Your forwarder will ask for both before quoting, and an airline will ask again.
How are spare batteries declared for shipping?
Spare batteries travel under different provisions from batteries installed in equipment, and the difference is where the risk sits: a loose battery has exposed terminals. Spare batteries need terminal protection, individual packaging, and a declaration that names them separately from the appliances. If you can avoid shipping spares, do: it removes a document layer and a refusal risk at the airline.
Can a portable blender go by air freight?
Yes, if the battery is declared and the packing instruction is followed. Consumer appliances usually fall within the small battery provisions, which have their own limits for cells and batteries. The practical constraint is that many forwarders accept battery cargo only on specific routings, so check acceptance before you promise a delivery date. The alternative is sea freight, which is slower but simpler.
Can I take a portable blender on an airplane?
As a passenger, you can usually carry battery-powered devices in cabin baggage, with spare batteries restricted to carry-on only and terminal protection required. Rules differ by airline and by country, and they change. For your listing, describe the battery capacity and advise the customer to check with the airline rather than promising that the product is accepted.
What is the difference between a battery installed in equipment and one packed with it?
Installed means the battery is inside the device and the device is the package. Packed with means the battery is in the same box but separate from the device. Installed is the simpler case for most appliances and the one most forwarders prefer, because the terminals are protected by the product. Packed-with shipments need the battery protected individually as well.
Which UN numbers apply to lithium ion appliances?
UN 3480 covers lithium ion batteries shipped on their own, and UN 3481 covers lithium ion batteries packed with equipment or contained in equipment. Lithium metal batteries use UN 3090 and UN 3091. The appliance you are shipping usually falls under UN 3481 when the battery is inside it. Your forwarder will confirm which entry applies to your packing configuration.
Does a hand warmer need air transport documents if it ships by sea?
Sea freight follows the IMDG Code rather than the air regulations, but the battery is still dangerous goods, so the shipment needs classification, packaging and documentation. The UN 38.3 test summary is still the underlying evidence that the battery type is safe to transport. Ask your forwarder which documents the carrier requires for a class 9 shipment on your route.
What happens if the battery is not declared?
The shipment can be refused, offloaded or held, and the shipper carries the consequences. Undeclared batteries are one of the reasons carriers audit appliance bookings. The cost is not only the delay: a refused booking near a sailing date usually means re-booking at a higher rate or switching mode. Declare the battery at quotation stage, not at booking.
