How to buy drone samples from China

Choose the right type of sample

Chinese drone suppliers usually offer three kinds of samples:

The further a sample moves from the standard model, the longer it takes and the more it costs. A custom sample also needs a clear agreement on who owns the design changes.

Lock the specification before you pay

Write down the configuration you expect to receive:

• Flight controller and firmware: proprietary or open platform (for example PX4 or ArduPilot), and the firmware versions.
• Positioning: the GNSS module and whether RTK is included.
• Radio links: the control, video and telemetry frequencies (such as 2.4 GHz, 5.8 GHz, 868 MHz or 915 MHz) and the transmit power setting.
• Camera or payload: the sensor, lens and gimbal.
• Battery: the cell type, capacity in Wh, connector and the number of spare batteries.
• Accessories: the remote controller, charger, cases and spare propellers.

Ask the supplier to confirm this list on the proforma invoice. It becomes the reference for testing the sample and, later, for approving a "golden sample" for volume production.

Check the destination market rules first

A sample built for the wrong market may be impossible to fly legally or to certify later.

• United States: drones that must be registered need Remote ID under FAA 14 CFR Part 89, either built in or by broadcast module. Radio equipment needs FCC equipment authorization.
• European Union: drones sold in the Open category carry a C-class label under Regulation (EU) 2019/945, with CE marking. Radio equipment must meet the Radio Equipment Directive. Transmit power limits in some bands, such as 5.8 GHz, are stricter than in other markets, so an export model for another region may not be compliant.
• Other markets: check local aviation registration, radio type approval and import rules before ordering.

Tell the supplier the destination country at the start. Ask which regional version of the hardware and firmware they will ship.

Check Chinese export controls

China controls the export of certain drones, payloads and components under its dual-use export control rules. A sample is not exempt because only one unit is shipped or because it is declared as a sample. Industrial aircraft, high-performance thermal cameras, long-range data links and some autopilots are among the items that may need an export licence, depending on their technical parameters.

Before paying, ask the supplier to state in writing whether the model and its payload fall under the current control list and, if so, who will apply for the licence and how long it may take. Rules change: confirm the current position for each order.

Understand sample pricing

Sample prices are normally higher than the unit price for volume orders. A single unit needs separate materials, calibration, a test flight and dangerous goods shipping. For standard models the sample price is often between one and three times the volume price. Custom samples are priced on the engineering work involved.

Agree in writing how the sample cost will be treated if you place a volume order. A common arrangement is that the sample premium, or the whole sample price, is credited against the first order once it reaches the agreed minimum quantity.

If you are comparing several suppliers, consolidating their samples in China before export usually costs less than receiving separate dangerous goods shipments from each factory.

Plan the shipping before the sample is ready

Most drones use lithium-ion or lithium-polymer batteries, which are Class 9 dangerous goods for transport.

• Batteries shipped on their own are UN 3480 and, by air, may only travel on cargo aircraft.
• Batteries packed with or installed in the drone are UN 3481.
• Capacity matters: batteries above 100 Wh need fully regulated dangerous goods shipping. A battery shipped by air under the relevant rules may also need to be at a reduced state of charge.

Ordinary express services may refuse a drone with batteries unless the shipper has a dangerous goods account. Ask the supplier for the battery's UN 38.3 test summary and Safety Data Sheet before booking. Our guide on shipping drones and lithium batteries from China explains the packing and documentation rules in more detail.

Allow realistic lead times

Total lead time is the build and test time, plus any export licence, plus transport:

• Standard samples: usually about one week to prepare, calibrate and test before dispatch.
• Light OEM samples: typically two to four weeks, depending on the changes.
• Custom samples: depend on the engineering work and are best agreed as a project schedule.
• Transport: a drone without batteries can travel by normal express in a few working days. With batteries, dangerous goods air services commonly take one to three weeks including document checks. Large batteries sent by sea take longer.

Ask for a written schedule with these stages separated, so delays can be traced.

Classify the sample correctly for import

Since HS 2022, unmanned aircraft have their own heading, 8806, subdivided by maximum take-off weight. Drone parts such as propellers and rotors are classified under 8807, and lithium-ion batteries under 8507.60.

Marking a sample "no commercial value" or under-declaring its price does not remove import duty or tax, and it can cause delays or penalties. Declare the real transaction value. Duty rates and any additional tariffs depend on the destination country and change over time, so check them before ordering.

Pay safely

Match the payment method to the value of the sample:

• For lower-value samples, use payment methods that offer buyer protection.
• For higher-value industrial samples, a bank transfer is common. The receiving account name must match the supplier's registered company name exactly. Do not pay into a personal account or an unrelated company's account.
• For custom samples, split the payment: a deposit to start the work and the balance after you have seen the test flight results, before dispatch.

You can check a Chinese supplier's registration details in the National Enterprise Credit Information Publicity System.

Test the sample before it leaves China

Returning a drone with batteries from abroad is difficult and often costs more than the sample itself. The most effective quality step is therefore an inspection and test flight in China before dispatch:

1. Configuration check: compare the flight controller, GNSS module, motors, speed controllers and battery against the agreed specification.

2. Bench checks: sensor and compass calibration, gimbal stability, video latency and link stability.

3. Flight test: at least one full battery cycle, including hover, manoeuvres, waypoint flight and the low-battery and signal-loss return-to-home functions. Keep the flight log.

4. Documents: confirm the battery documents, labels and serial numbers match the unit being shipped.

Ask for the test video and flight log with the unit's serial number visible.

Agree what happens if the sample is faulty

Because return shipping is hard, agree in advance how faults will be handled. Practical options include free replacement modules sent without batteries, such as a gimbal, speed controller or flight controller, remote diagnosis using the flight log, or a credit against the volume order. Write the chosen remedy into the order.

Approve the golden sample

When the sample passes your tests, record its configuration, firmware versions and any agreed changes. Keep one signed unit with each party where possible. This golden sample becomes the reference for production inspection.
