When a DJI smart battery starts misbehaving — swollen cells, refusal to charge, sudden voltage drops — most owners instinctively think, “I’ll ship it to a repair specialist.” That’s exactly the right impulse, but getting a lithium battery from Hong Kong to a Japanese repair facility via FedEx or DHL quickly turns into a compliance puzzle. This guide pulls together what you need to know to build a reasoned, documentation-complete shipment. It is written from an operational perspective, not as legal advice, and it acknowledges that regulations change — you must verify everything with your carrier and the relevant authorities.

We will focus on the Hong Kong–Japan corridor, but the same principles apply when you are shipping batteries from Austin to China for a trade-in, sending a drone from the Netherlands to DJI’s repair centre in Shenzhen, or moving a used DJI unit from China to the UK. Where those routes impose extra local checks, we highlight what to look for, without inventing specifics we cannot source.

Understanding your battery: UN3480 vs UN3481

The IATA Dangerous Goods Regulations classify lithium-ion batteries under two core UN numbers that determine how strict your shipment preparations need to be.

UN3480 – Lithium-ion batteries shipped alone (spare/loose) This covers a standalone intelligent flight battery, not packaged with the drone and not installed in any equipment. UN3480 is the most tightly regulated category. For most passenger-aircraft scenarios, standalone lithium-ion batteries are forbidden unless explicitly permitted under a competent authority approval. FedEx and DHL typically move such batteries on cargo-aircraft-only (CAO) services, and specific operator variations apply. If you are sending a battery back for repair without the drone, you will almost certainly be shipping under UN3480.

UN3481 – Lithium-ion batteries packed with or contained in equipment When you ship the whole drone with the battery installed in the aircraft body, or you pack the battery in the same box alongside the drone, it falls under UN3481. This classification is comparatively less restrictive — passenger aircraft acceptance is often possible, subject to the carrier’s own approval. Many repair services prefer to receive the full aircraft so they can test the battery with the drone’s power management board. That works in your favour: UN3481 generally simplifies the logistics.

A practical starting point is to ask the repair centre whether they can accept the whole unit and, if so, to follow their shipping instructions precisely.

IATA 2024 dangerous goods framework: what matters for DJI batteries

You don’t have to memorise the entire DGR. Focus on these operational takeaways:

• State of charge: The current IATA recommendation is that lithium-ion batteries not exceed 30% state of charge for transport. For a DJI battery, use the built-in LED indicator or leave the battery to self-discharge to roughly two solid LEDs before packaging.
• Packing instructions:
• PI 965 (UN3480, standalone)
• PI 966 (UN3481, packed with equipment)
• PI 967 (UN3481, installed in equipment)
• Label and mark your package: The lithium battery handling label is required, along with a “Cargo Aircraft Only” label if the battery is restricted to CAO. Outer packaging must have a clear UN number and proper shipping name, e.g. “UN3480, Lithium-ion batteries”.
• Quantity limits: Carriers impose net-quantity limits per package, often stricter than IATA’s baseline. FedEx and DHL publish their own variation sheets; confirm the latest edition before booking.
• DG training: Anyone offering a dangerous goods shipment must have appropriate training. If you are an individual sender, you will likely work with the carrier’s DG desk, who will guide you through the formalities. You cannot simply drop a battery off at a service point.

These rules also govern shipments from Austin to China, the Netherlands to Shenzhen, or China to the UK. The IATA framework is global, but individual states add import controls and operator approvals on top — a fact we address later in the customs section.

FedEx vs DHL for a Hong Kong–Japan battery shipment

Both integrators handle lithium-battery dangerous goods, but the day-to-day experience varies depending on your account setup. The table below captures operational differences that help you choose a path. These points are based on general practice; always check live service advisories.

The choice often comes down to which carrier your repair centre already works with and whether your shipment is UN3480 or UN3481. For UN3481 with the drone installed, passenger-aircraft shipping may be available, which can lower cost and transit time.

Required documentation: MSDS, DGD, and repair invoice

Material Safety Data Sheet (MSDS/SDS)

A Safety Data Sheet for the DJI battery model you are shipping demonstrates to the carrier and customs that you know the chemical composition, watt-hour rating, and emergency response information. DJI publishes data sheets for their intelligent flight batteries; request the current version from DJI support or download it from their official support portal. The MSDS must be from the battery manufacturer or a qualified third party — you cannot write your own.

Dangerous Goods Declaration (DGD)

The DGD is a formal document required for UN3480 and many UN3481 shipments. It describes the goods, UN number, packing instruction, quantity, and emergency contact number. FedEx and DHL provide templates that match IATA’s layout. A 24-hour emergency response telephone number for the shipper is mandatory; many specialised DG service providers sell this service if you do not have an in-house number.

Commercial invoice for repair and return

A regular sale invoice risks triggering import duties and VAT in Japan, even for a temporary repair. Instead, state the following clearly on the commercial invoice:

• “Temporary export for repair and return”
• Value for customs purposes only, not a sale
• Description: “Used DJI [model] battery, xx Wh, shipped for repair, no commercial value”
• HTS code: lithium-ion accumulator code appropriate to Japan (check with the repair centre or your customs broker)

This approach helps the Japanese customs office process the shipment under temporary admission relief, but it is never a guarantee. The repair centre in Japan must be prepared to provide an import declaration or a pro-forma repair order if requested. If you are sending from the Netherlands to DJI Shenzhen, China has its own repair-return procedure; similarly, China-to-UK shipments need to navigate UK customs rules. Always ask the receiving repair shop to specify exactly what they want on the face of the invoice.

Packing your DJI batteries so they arrive safely and compliantly

Even a seasoned shipper can miss packaging details that cause inspections or returns. Here is a practical sequence that lowers the chance of rejection:

1. Tape exposed terminals — Use electrical tape over the metal contacts of each battery to prevent short circuits. For an intelligent battery with flush contacts, consider placing it inside an anti-static bag and taping the bag closed.
2. Wrap each battery individually — Non-conductive cushioning material should separate batteries from each other and from other items in the same package.
3. Use a strong outer box — A double-wall corrugated fibreboard box rated for the weight. Lithium battery labels must not be affixed over seams or closures.
4. Add absorbent and cushioning — Enough foam or packing material to prevent movement and to contain any inadvertent electrolyte leakage, though this is a low-probability event with Li-ion pouches.
5. Attach the lithium battery mark and, if required, the CAO mark — The lithium battery handling label must include the UN number(s) and be at least 100 mm × 100 mm. For FedEx/DHL, you can usually print a combined label from their DG tools.
6. Package the documentation pouch — Attach a clear envelope containing the MSDS, DGD (if not submitted electronically), and the repair invoice.

If you would rather not perform every check yourself, see how Reboot Hub standardises its own multi-point bench test and grading process for pre-owned drones. That same rigour applies when we prepare units for shipment.

Customs: Hong Kong export and Japan import

Hong Kong side Hong Kong does not impose export duties on most goods, and lithium batteries leaving the territory are not subject to an export licence under typical circumstances. However, you must comply with the Civil Aviation Department’s dangerous goods regulations and the chosen carrier’s conditions. The carrier will file the Security and Dangerous Goods (Large Pack) declaration where needed; you must supply accurate DG data. For a non-commercial repair shipment, no separate Hong Kong customs export declaration is usually required for the invoice, but keep all records in case of post-shipment queries.

Japan side Japan strictly enforces lithium battery import regulations. A repair-return shipment can often enter under temporary admission, but the importer of record (typically the repair centre, or you if you act as a private importer) must arrange customs clearance. Japanese customs may request:

• The repair estimate or repair order letter from the receiving facility
• A statement explaining that the item will be re-exported after repair
• Evidence of ownership, such as original purchase invoice

If any duty or consumption tax is assessed, it is usually refunded or not collected when the repaired item is re-exported, provided the temporary admission procedure was correctly followed. These points illustrate the importance of coordinating ahead of shipment; a last-minute customs hold can cause delays or storage fees.

Region-specific scenarios in brief

Shipping from Austin, Texas to China for a DJI trade-in Under US export regulations, a lithium battery intended for trade-in is still a dangerous goods shipment. You must follow IATA PI 965 or 967, and provide a commercial invoice stating “trade-in repair / refurbishment” to help Chinese customs identify the non-sale nature. China requires battery importers to hold certain accreditation; a recognised repair centre like DJI Shenzhen will guide you through the correct consignee details. Check with the US Bureau of Industry and Security if you are uncertain about export classification.

Shipping from the Netherlands to DJI Shenzhen via DHL European operators must observe ADR rules for road transport to the DHL gateway, after which IATA applies. DHL’s DG desk in the Netherlands can advise on their specific lithium battery acceptance policy for UN3480. Dutch customs do not typically restrict the export of used lithium batteries for repair, but you should retain the export declaration proof. Shenzhen import clearance is facilitated when the consignee is a DJI-authorised repair centre that can provide import documents.

Shipping a used DJI drone from China to the UK Post-Brexit, UK customs treat the repair-return scenario under the Temporary Admission procedure. The consignee in the UK must be a known repair business or an individual prepared to complete a customs entry. A commercial invoice marked “goods sent for repair and return, not a sale” is essential. Lithium battery rules mirror the IATA framework, though operators may impose additional restrictions on China-originating lithium-battery shipments. Contact your chosen integrator’s UK DG team to verify current serviceability.

For any route not covered by the above, the safest approach is to request written shipping guidance from the repair centre and to telephone the DHL or FedEx dangerous goods hotline before preparing a single label.

Practical pre-shipment checklist

If any step feels uncertain, an experienced freight forwarder or the carrier’s own DG specialist can walk you through the specifics. What you should not do is guess and hope; a rejected shipment can strand a battery in a warehouse without proper storage conditions.
