Sourcing petrol model aero engines from China
Selected heading 8407 lines carry 0% to 4% UK duty on goods from China, depending on classification. Confirm the code before using the aircraft-engine rate. Engines supplied for consumer use in Great Britain must be safe. Check propeller mounting, ignition and running performance. Cambridge China Bridge sources petrol model aircraft engines.
UK duty and model-engine classification
Heading 8407 covers spark-ignition reciprocating or rotary internal combustion piston engines. This guide concerns separate petrol engines for model aircraft. The table compares general engine lines by displacement and power, alongside the aircraft-engine line. Its inclusion does not establish that a model engine qualifies for that line.
Read from the UK Trade Tariff on 1 October 2026, the selected general engine lines carried 2% or 4% duty on goods from China, while the selected aircraft-engine line carried 0%. These selected lines showed no anti-dumping or countervailing duty, suspensions or attached import controls. Garden-equipment suspensions elsewhere in the heading do not establish eligibility for a model-aircraft order.
Give your customs broker the engine drawings, displacement, rated power, ignition details and intended application to confirm the commodity code. For the wider heading, see petrol motorcycle engines. Confirm classification before using the illustrative order calculation.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other engines, cylinder capacity not exceeding 250 cm³ | 8407 90 10 90 | 2% | None |
| Other engines above 250 cm³, power not exceeding 10 kW | 8407 90 80 90 | 4% | None |
| Other engines above 250 cm³, power exceeding 10 kW | 8407 90 90 90 | 4% | None |
| Aircraft engines, other: comparison line requiring classification confirmation | 8407 10 00 90 | 0% | None |
Specify the propeller mounting and ignition
Specify displacement, cylinder arrangement, operating cycle, installed weight and mounting-hole positions. Record the propeller-hub dimensions, fixing threads, rotation direction and permitted propeller combinations. Include the carburettor position, throttle travel, exhaust outlet and clearance around the cylinder and spark-plug cap. Identify whether the ignition module, muffler, mounting hardware and fuel fittings are included.
Agree the fuel and lubricant specification, starting procedure and running test with the factory. Ask a compliance adviser to assess the engine and supplied ignition assembly for the intended market before agreeing marking or certification claims. For consumer supply in Great Britain, the product must be safe; assess propeller contact, hot surfaces, fuel leakage, exhaust exposure and vibration.
Worked duty example
Illustrative example, not a quote: Illustrative batch of 20 petrol model aircraft engines, subject to code confirmation under 8407 90 10 90, invoiced at £2,000 free on board, with £300 of freight and insurance to the UK. The customs value is £2,300. Duty at 2% is £46. Import VAT at 20% is charged on the customs value plus duty, £2,346, so it is £469.20. Import taxes total £515.20; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £46 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Fit: measure mounting positions and propeller-hub fittings against the approved drawing; check threads, fasteners and exhaust clearance.
Running: use a securely mounted test rig and an agreed propeller; record starting, idle stability, throttle response, vibration and ignition cut-off.
Condition: inspect castings, crankshaft movement, spark-plug connections and fuel fittings; check for leakage after running and transit damage on arrival.
Identification: match engine and ignition-module references to the order; check batch identification and instructions covering fuel, propeller fitting and safe starting. Arrange quality inspection around these checks.

What goes wrong
A factory demonstration can conceal a mismatch with your installation. A different propeller, fuel mixture or ignition supply may change starting and running behaviour. Loose hubs, damaged plug caps, poor carburettor adjustment and exhaust interference are useful failure points to check. Retain the approved sample, test conditions and results so a repeat batch can be compared.
Do not accept an aircraft-engine description as sufficient support for zero duty. Resolve classification before dispatch and agree how defective engines will be identified, investigated and replaced. Once the product is on the market, responsibility for its safety continues. Include gaskets, ignition components and carburettor parts in the support agreement.

Frequently asked questions
What is the UK import duty on petrol model aircraft engines from China?
The selected general engine lines carry 2% or 4%; the aircraft-engine comparison line carries 0%. Confirm the model engine's classification before declaring it. These selected lines show no anti-dumping or countervailing duty.
Does a model aircraft engine automatically qualify for zero duty?
Do not assume it does. Ask your broker to confirm the code using the engine specification and intended application before using the aircraft-engine rate.
What should I ask the Chinese factory to test?
Agree a propeller, fuel specification and ignition supply. Check starting, idle stability, throttle response, vibration, leakage and ignition cut-off, and retain the results against the engine reference.
What safety information should accompany the engines?
Ask for clear instructions on propeller fitting, fuel preparation, starting, stopping, hot surfaces and maintenance. Check that the instructions match the supplied engine and ignition module.
