Sourcing turbine combustion chambers from China
Gas turbine combustion chambers from China carry 0% UK duty across the relevant parts lines of heading 8411. Confirm which product safety rules cover the supplied component before selling or installing it, and match its alloy, cooling passages and interfaces to the approved drawing. Cambridge China Bridge sources gas turbine combustion chambers.
0% duty on the relevant turbine parts lines
Read from the UK Trade Tariff on 12 October 2026, heading 8411 covers turbojets, turbopropellers, other gas turbines and their parts. This guide concerns combustion chambers and liners supplied separately. The relevant parts lines carry 0% duty for goods from China, with no anti-dumping or countervailing measures, suspensions or attached import controls recorded in the supplied tariff data.
Industrial turbine chambers are candidates for 8411 99 00 99; turbojet and turbopropeller chambers have separate parts lines. Confirm the application and commodity code with your broker. Repeated table codes distinguish chamber and liner applications, rather than separate tariff subdivisions. For complete engines and the wider heading, see micro gas turbine engines. For separate shaft purchases, see our guide to sourcing gas turbine shafts. For complete turboshaft purchases, see our turboshaft engine sourcing guide.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Industrial gas turbine combustion chambers | 8411 99 00 99 | 0% | None |
| Turbojet or turbopropeller combustion chambers, other | 8411 91 00 90 | 0% | None |
Specify the chamber, liner and turbine interface
Give the factory the turbine model, part identity and approved drawing revision. Define whether the order includes the outer casing, liner, dome, transition connection, fuel injectors, igniter fittings and seals. Specify alloy composition, material condition, weld procedures, heat treatment, coating, cooling-hole geometry and mounting tolerances. Agree dimensional, weld and flow-test acceptance criteria before production. For casing procurement, see our gas turbine casing sourcing guide.
Ask a compliance adviser to determine the supply's status before sale in Great Britain. Machinery supply rules govern placing machinery on the market or putting it into service. If classified as partly completed machinery, the supply needs comprehensive safe-incorporation instructions and a declaration of incorporation. Where within scope, pressure-equipment rules regulate design, manufacture and conformity assessment above 0.5 bar maximum allowable pressure; ask the adviser to check exclusions for the exact design.
Worked duty example
Illustrative example, not a quote: Illustrative order: one replacement industrial gas turbine combustion chamber under 8411 99 00 99, invoiced at £8,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £9,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £9,200, so it is £1,840. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.
Inspection checklist
Identity: match the part marking, drawing revision and material certificates to the delivered chamber and its manufacturing records.
Geometry: measure mounting faces, flange positions, liner clearances and injector openings against the drawing; inspect cooling holes for blockage and machining burrs.
Welds and coating: review the agreed non-destructive examination records, inspect weld surfaces and check coating coverage, damage and recorded thickness.
Arrival: inspect for distortion, dents, corrosion and loose debris before assembly. Match seals and fittings to the packing list, and retain the inspection record.

What goes wrong
A chamber can fit its mounting flange yet have the wrong cooling-hole pattern, liner clearance or injector position. Alloy substitutions, incomplete heat-treatment records, weld defects and coating damage can undermine the agreed design. Compare production records with the actual part, rather than accepting photographs or a material certificate without traceability.
A generic CE certificate does not establish compatibility with your turbine. Have the integration engineer review the supplied configuration and agree commissioning checks before installation. Use testing and certification support to review the proposed assessment and evidence before committing to production.

Frequently asked questions
What is the UK import duty on gas turbine combustion chambers from China?
The relevant heading 8411 parts lines carry 0% duty in the supplied tariff data, with no anti-dumping or countervailing measures. Confirm the precise code from the turbine application and supplied configuration.
Which commodity code covers an industrial turbine combustion chamber?
8411 99 00 99 is a candidate for an industrial gas turbine chamber supplied as a part. Turbojet and turbopropeller parts use different lines. Give your broker the drawing, turbine application and contents of the shipment.
Does a combustion chamber need CE or UKCA marking?
Ask a compliance adviser to establish the supplied component's status and applicable rules. If it is partly completed machinery, obtain safe-incorporation instructions and a declaration of incorporation.
What should I request from the Chinese factory?
Request the approved drawing, traceable alloy certificates, heat-treatment and weld records, coating records, dimensional results and agreed flow-test results. Define whether injectors, igniter fittings and seals are included.
