Shipping Battery Products to the US: Built-in, Accompanied and Standalone Compared
Built-in lithium batteries ship with paperwork; standalone batteries are a different game. Know the three categories, the documents, and the packing that prevents rejection.
Three Categories, Three Sets of Rules
| Category | Examples | Shipping rules |
|---|---|---|
| Built-in lithium | Earbuds, small appliances | Battery-accepted channels, UN38.3 + MSDS, ≈15% uplift |
| Accompanied lithium | Spare batteries shipped with a device | Stricter packing; batteries separated and protected |
| Standalone lithium | Power banks, spare cell packs | Most limited — some channels refuse; dedicated battery line |
The Paperwork
- UN38.3 test summary — issued by the battery manufacturer; ask for it before stocking a product.
- MSDS — describes chemistry (lithium-ion vs lithium-metal matters: metal cells face air restrictions).
- Correct labeling — the lithium battery mark on the carton, with the watt-hour rating where required.
Packing That Prevents Rejection
- Power each device off, not standby.
- Terminal protection on every battery: original retail packaging or non-conductive caps.
- Cushion so devices cannot shift; one moving item in transit is how X-ray operators flag a carton.
Watt-Hour Rules of Thumb
Under 100Wh per battery is the broadest acceptance band — most consumer products qualify. 100-160Wh needs carrier approval. Above 160Wh is effectively cargo-freight territory.
Declare honestly and send documents with the first inquiry — we confirm channel acceptance before anything ships.
