Sourcing wood-chip boilers from China
Wood-chip central heating boilers from China carry 2% UK duty; boiler parts carry 0%. Solid-fuel ecodesign rules cover boilers with rated heat output up to 500 kilowatts. Match the model and its test evidence to the intended wood-chip fuel before ordering. Cambridge China Bridge sources wood-chip central heating boilers.
2% duty on boilers, 0% on boiler parts
Read from the UK Trade Tariff on 1 October 2026, heading 8403 covers central heating boilers other than those of heading 8402, together with their parts. For wood-chip boilers, distinguish cast-iron construction from other construction. Separate boiler parts have their own lines.
The supplied tariff facts show 2% duty on complete boilers from China and 0% on boiler parts. They record no anti-dumping or countervailing measures, suspensions or attached import controls for these lines. Import VAT is normally 20%; see UK import duty and VAT.
Confirm the commodity code using the construction, function and shipment contents. Do not assume that separately supplied fuel-handling machinery belongs under the boiler-parts code. For related products within this heading, see wood-pellet central heating boilers.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cast-iron wood-chip central heating boilers | 8403 10 10 00 | 2% | None |
| Other wood-chip central heating boilers | 8403 10 90 00 | 2% | None |
| Cast-iron parts for central heating boilers | 8403 90 10 00 | 0% | None |
| Other parts for central heating boilers | 8403 90 90 00 | 0% | None |
Specify the chips, feed system and heat demand
Specify the intended chip size, moisture range, fines content and acceptable contaminants. Agree heat output, operating pressure, water connections, hopper arrangement, agitator, auger geometry, ash removal and access for cleaning. Ask the installer to review the flue connection, buffer arrangement, electrical supply and controls before approving the model.
For Great Britain, solid-fuel ecodesign requirements cover ordinary wood-chip heating boilers with rated heat output up to 500 kilowatts. In-scope boilers up to 70 kilowatts also have energy-labelling and supplementary product-information requirements. A declaration of conformity must be supported by technical documentation. Request model-specific efficiency and emissions reports, the applicable label and installation instructions.
The ecodesign test rules address the preferred fuel and other declared suitable fuels, with a specific allowance for chipped-wood moisture categories. Check what fuel was actually tested. Before choosing a boiler for a smoke control area, check that the exact appliance is exempt for the intended wood fuel. Confirm site permitting with the relevant authority; permit requirements depend on the fuel type and amount burned.
Worked duty example
Illustrative example, not a quote: Illustrative order: 2 wood-chip 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 handling: run representative chips through the hopper, agitator and auger; check bridging, blockage detection, motor loading and safe access to moving parts.
Combustion and controls: witness ignition, steady operation and shutdown; check sensor readings, overheating protection and the agreed measures against fire travelling back towards the fuel store.
Water circuit: inspect welds, seals and connections; witness the agreed pressure test and check for leaks, insulation gaps and damage to the heat exchanger.
Documents and arrival: match model identifiers to the declaration, reports and applicable energy label; check manuals, spare parts, lifting points, packing damage and moisture ingress. Agree the scope through quality inspection.

What goes wrong
A pellet demonstration leaves chip handling unproven. Oversized pieces can obstruct the auger, while uneven moisture can make combustion unstable. Specify acceptance tests with representative chips and record the fuel used alongside the operating results.
A changed controller, heat exchanger or feed system can leave the delivered model different from the tested model. Compare the final specification with the evidence before shipment, then inspect connections and packing on arrival. Agree access to grates, igniters, sensors and control parts before ordering.

Frequently asked questions
What is the UK import duty on wood-chip boilers from China?
The supplied tariff facts show 2% on complete central heating boilers and 0% on boiler parts, with no recorded anti-dumping or countervailing measures.
Do wood-chip boilers need an energy label?
Ordinary wood-chip central heating boilers with rated heat output up to 70 kilowatts fall within the solid-fuel boiler energy-labelling rules. Check the exact model and its product information.
Can I use a wood-chip boiler in a smoke control area?
Wood can only be burned in an exempt appliance in a smoke control area. Check the exact boiler and its permitted fuel before ordering.
Is a test using pellets enough for a wood-chip boiler?
Check reports covering the declared wood-chip fuel. The ecodesign rules address preferred and other suitable fuels, with an allowance between specified chipped-wood moisture categories.
