Sourcing combine diesel engines from China
The selected combine-harvester diesel engine lines carry a uniform 4% UK duty from China, with no anti-dumping duty recorded. Confirm the engine type-approval and marking requirements for new non-road mobile machinery in Great Britain with the Vehicle Certification Agency. Cambridge China Bridge sources combine-harvester diesel engines.
4% duty on the selected engine lines
Heading 8408 covers compression-ignition piston engines. This guide concerns diesel engines supplied separately for combine harvesters. Choose the line using the engine's condition, intended application and rated power. Do not select a tractor-engine line simply because the engine will work on a farm.
Read from the UK Trade Tariff on 1 October 2026, the selected used and new engine lines carried 4% duty on goods from China. These rows record no anti-dumping or countervailing duty, suspension or attached import control. This tariff position does not establish emissions compliance.
Give your broker the engine specification, rated power, condition and intended harvester installation to confirm the commodity code. For the wider heading and tractor applications, see agricultural tractor diesel engines.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Used combine-harvester diesel engines | 8408 90 27 90 | 4% | None |
| New combine-harvester engines, over 100 kW up to 200 kW | 8408 90 61 90 | 4% | None |
| New combine-harvester engines, over 200 kW up to 300 kW | 8408 90 65 90 | 4% | None |
| New combine-harvester engines, over 300 kW up to 500 kW | 8408 90 67 90 | 4% | None |
Specify the harvester installation
Identify the harvester model and original engine before asking for a replacement. Specify the torque curve at working speed, flywheel and housing, mounting positions, rotation, accessory drives and available engine-bay space. Agree whether the supply includes the cooling pack, wiring, controller, sensors and exhaust after-treatment.
For a new-machine installation in Great Britain, confirm the applicable engine emission type-approval and marking requirements with the Vehicle Certification Agency. Type approval demonstrates that the engine meets the latest emissions standards. Ask which approval certificate applies and match it to the engine offered. For an older harvester replacement, have an approval specialist confirm the applicable route before ordering.
Specify cooling performance under sustained harvesting load and dusty conditions. Agree radiator access for cleaning, air-intake routing, exhaust clearances, diagnostic access and a parts list. Record the controller settings and software identification so later replacements match the delivered engine.
Worked duty example
Illustrative example, not a quote: Illustrative order: a new combine-harvester diesel engine under 8408 90 61 90, invoiced at £28,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 4% is £1,280. Import VAT at 20% is charged on the customs value plus duty, £33,280, so it is £6,656. Import taxes total £7,936; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,280 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the engine model, serial number, approval marking and documents to the purchase order. Photograph the identification plate before dispatch and on arrival.
Fit: measure mounting points, flywheel connections, sump clearance and cooling connections against the agreed installation drawing. Check the supplied harness and controller connectors.
Loaded running: witness a bench test at the agreed working speeds and loads. Record torque, power, coolant temperature and oil pressure; inspect for leaks after the engine is warm.
Arrival: check mounting brackets, connectors, exhaust components and protective caps for transit damage. Confirm accessories, manuals and spares against the packing list. Agree the scope through quality inspection.

What goes wrong
An engine can fit the mounting frame yet fail to match the harvester's torque demand or control system. A brief unloaded demonstration does not show sustained cooling performance. Missing after-treatment components, incompatible sensors and altered controller settings can turn an apparently complete engine into an installation project.
Avoid accepting a shared engine-family name as proof of compatibility. Put the installation drawing, accessory list, approval documents and loaded-test acceptance criteria into the order. Agree responsibility for diagnosis, installation support and replacement parts before shipment.

Frequently asked questions
What is the UK import duty on combine-harvester diesel engines from China?
The selected used and new engine lines carry 4% duty, with no anti-dumping or countervailing duty recorded in the supplied tariff snapshot.
Does a new combine-harvester engine need emissions approval?
Confirm the engine type-approval and marking requirements for new non-road mobile machinery sold in Great Britain with the Vehicle Certification Agency. Obtain the applicable matching approval certificate before ordering.
Can I buy an engine to replace an older combine engine?
Start with the original engine identity and harvester details. Ask an approval specialist to confirm the applicable route, then verify fit, controls, cooling and torque.
What test should I request before shipment?
Request a loaded bench test at the agreed working speeds. Record power, torque, coolant temperature and oil pressure, then check for warm-engine leaks.
