Sourcing wood pellet boilers from China
Wood pellet central heating boilers from China carry 2% UK duty; boiler parts carry 0%. For Great Britain, check the model's applicable solid-fuel ecodesign and energy-labelling requirements before ordering, alongside its suitability for smoke control areas. Cambridge China Bridge sources wood pellet central heating boilers.
2% on complete boilers, 0% on boiler parts
Heading 8403 covers central heating boilers other than those of heading 8402. This guide focuses on wood pellet boilers supplying a water-based heating circuit, together with identifiable boiler parts. The tariff separates cast iron boilers and parts from those of other materials.
Read from the UK Trade Tariff on 11 October 2026, complete boilers from China carry 2% duty and boiler parts 0%. The supplied tariff data lists no anti-dumping or countervailing measures, suspensions or attached import controls for these lines. Import VAT is normally 20%.
Confirm the commodity code from the construction and the goods actually shipped. Do not assume that separately supplied feeders, pumps or controllers qualify as boiler parts. See the wider central heating boiler guide for other boiler types.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cast iron wood pellet central heating boilers | 8403 10 10 00 | 2% | None |
| Other wood pellet central heating boilers | 8403 10 90 00 | 2% | None |
| Cast iron parts of central heating boilers | 8403 90 10 00 | 0% | None |
| Other parts of central heating boilers | 8403 90 90 00 | 0% | None |
Specify the pellet feed, combustion and water circuit
Specify heat output, modulation, accepted pellet characteristics, hopper arrangement, auger access, ignition system and ash removal. Agree the water connections, operating pressure, buffer arrangement, flue connection and service clearances with the intended installer. Ask for model-specific combustion and efficiency reports using the proposed fuel.
For models within the applicable ecodesign scope, obtain the declaration of conformity and supporting technical documentation. The importer first placing a regulated product on the Great Britain market is responsible for compliance. For models within energy-labelling scope, obtain the energy label, product fiche and supporting documentation; dealers must display the label when selling.
For intended use in a smoke control area, check the exact model and fuel combination before ordering. Unauthorised fuels such as wood can only be burned in exempt appliances there, and users must follow the manufacturer's permitted fuel types. Use testing and certification support to review the model evidence.
Worked duty example
Illustrative example, not a quote: Illustrative order: 40 wood pellet central heating boilers under 8403 10 90 00, 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 2% is £640. Import VAT at 20% is charged on the customs value plus duty, £32,640, so it is £6,528. Import taxes total £7,168; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £640 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Fuel feed and ignition: run the agreed pellets through the hopper and auger; check bridging, ignition, flame stability, restart and the specified protection against burn-back.
Combustion and cleaning: compare sampled performance with the agreed reports; check door seals, ash drawers, cleaning mechanisms and access to the heat exchanger.
Water circuit and controls: inspect welds and connections, record pressure-test results against the specification, and exercise sensors, pumps, alarms and safety shutdowns.
Documents and arrival condition: match model identifiers to reports, label and fiche where applicable; check manuals, spare igniters and seals, pallet restraint, crushed panels and moisture damage. Plan quality inspection before dispatch and record arrival defects.

What goes wrong
A sample can run well while production units use different igniters, controllers or auger motors. Pellet feed can bridge, door seals can leak, and inaccessible ash passages make servicing difficult. Agree the component list and test fuel, retain the approved sample, and require approval before substitutions.
A report for a related model does not establish the performance of the shipped boiler. Smoke-control suitability also needs a separate model-and-fuel check. Arrange replacement igniters, sensors, seals and controller support before committing to stock, and have the intended installer review the hydraulic and flue drawings.

Frequently asked questions
What is the UK import duty on wood pellet boilers from China?
The supplied tariff data shows 2% on complete central heating boilers and 0% on boiler parts, with no listed anti-dumping or countervailing measures.
Do wood pellet boilers need an energy label?
Models within energy-labelling scope need an energy label, product fiche and supporting technical documentation. Dealers must display the label when selling, including online.
Can a wood pellet boiler be used in a smoke control area?
Check the exact appliance and fuel. Unauthorised fuels such as wood can only be burned in exempt appliances in smoke control areas; use only fuel types permitted by the manufacturer.
What should I ask the Chinese boiler factory for?
Ask for model-specific combustion and efficiency reports, the applicable conformity documents, hydraulic and flue drawings, the component list, a pellet-feed demonstration and a spare-parts plan.
