Quick Summary: Almost every modern diagnostic tablet contains a lithium-ion battery, which makes your shipment dangerous goods in transport. The rules are entirely manageable — UN 38.3 evidence, correct classification, packaging, marking and declaration — but skipping any one of them gets shipments delayed, rejected or fined. Here’s the working process for China → Australia/New Zealand.
Why Your Scan Tool Is “Dangerous Goods”
Lithium batteries can short-circuit, overheat and propagate fire, so transport law treats them as Class 9 dangerous goods with their own regime of testing, packaging and documentation. It doesn’t matter that the product is a professional tool rather than a hoverboard — classification follows the battery, not the marketing category.
For a typical diagnostic tablet shipment, the goods fall under the “lithium-ion batteries contained in equipment” classification (UN 3481). Spare battery packs shipped on their own are a different classification (UN 3480) with stricter air rules — including state-of-charge limits and, as cargo, exclusion from passenger aircraft. Mixing the two in one consignment without declaring both is a classic self-inflicted hold-up.
The Non-Negotiable: UN 38.3
Every lithium battery in transport must have passed the UN 38.3 test series (altitude, thermal, vibration, shock, short circuit and more), and since 2020 manufacturers and distributors must be able to produce a UN 38.3 test summary on request. Before your first order:
- Ask the factory for the UN 38.3 test summary for the exact battery model in your device.
- Check the summary matches the cell/pack model and manufacturer on the battery label — mismatches are common when factories switch cell suppliers.
- Keep it on file and give it to your freight forwarder before booking, not when asked.
Warning: A missing or mismatched UN 38.3 summary is the single most common reason lithium shipments get stopped. It costs nothing to verify before production and can cost weeks after booking.
Air vs Sea: How the Rules Differ
| Factor | Air (IATA DGR) | Sea (IMDG) |
|---|---|---|
| Strictness | Strictest — per-package limits, airline-specific rules on top | More forgiving for volume shipments |
| Batteries in equipment (UN 3481) | Generally accepted with correct marking and limits | Accepted; standard DG process |
| Spare batteries alone (UN 3480) | Cargo aircraft only, state-of-charge limits apply | Accepted with DG declaration |
| Cost of errors | Offload, rejection, airline blacklisting | Rollovers, port storage fees |
| Best for | Urgent small consignments | Planned replenishment |
The mode decision itself is covered in the sea vs air decision framework; batteries shift the equation toward sea for anything that can be planned.
The Shipping Process That Works
- Classify honestly. Batteries in equipment, packed with equipment, or alone — plus watt-hour ratings per battery. Your forwarder classifies from what you tell them; wrong input, wrong paperwork.
- Collect documents before booking: UN 38.3 summary, MSDS/SDS for the battery, packing list showing battery details, and the DG declaration where required.
- Pack and mark to the rule set: the lithium battery mark with UN number on the outer carton, quantities within per-package limits, batteries protected from short circuit and movement.
- Use a forwarder who ships DG weekly, not one who “can handle it”. Ask directly how many lithium consignments they move on your lane — the answer tells you everything.
- Brief the factory on carton marking. Most rejections start on the factory floor with the wrong label printed — or the right label covered by tape.

Frequently Asked Questions
Do small quantities escape the rules?
Smaller batteries within certain watt-hour limits ship under simplified provisions — less paperwork, but still marking, quantity limits and UN 38.3 evidence. “Excepted” never means “exempt from everything”, and courier channels enforce this aggressively.
Can I ship spare battery packs by air with the tablets?
Yes, but they’re declared separately (UN 3480 rules for the spares), and as cargo they move on freighter aircraft with state-of-charge limits. Many importers simply put spares on sea freight and keep air for finished units.
Whose job is DG compliance — mine or the forwarder’s?
The shipper owns the declaration; the forwarder executes it. In practice it’s collaborative, but if the paperwork is wrong, the consequences land on the party who declared — which is why you keep your own copies of the UN 38.3 summary and SDS rather than trusting that “the factory sent something”.
Key Takeaways
- Lithium batteries make your shipment dangerous goods — classification follows the battery, not the product category.
- UN 38.3 test summary: verify it matches your exact battery before production, hold it on file.
- Batteries in equipment (UN 3481) and spare packs (UN 3480) follow different rules — declare both.
- Sea freight for planned volume, air for genuine urgency, and a forwarder who moves DG weekly.
- Keep the quick reference next to your booking process.
