Sourcing gas turbine casings from China
Gas turbine casings from China carry 0% UK duty across the selected parts lines, with no anti-dumping or countervailing duty recorded. Choose the code from the turbine type and exact housing specification, and check product-safety scope separately. Cambridge China Bridge sources gas turbine casings.
Gas turbine casing duty and classification
Read from the UK Trade Tariff on 4 October 2026, heading 8411 covers turbojets, turbopropellers and other gas turbines, including their parts. The selected casing-related lines all carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, steel measure or suspension for these lines.
Separate turbojet and turbopropeller casings from casings for other gas turbines. The aircraft-specific line has a particular intended-use description; ask your broker to confirm that it fits the order. The turbocharger housing line applies to its stated wheel insertion hole dimensions. It is a boundary case, rather than a general code for stationary turbine casings.
The tariff attaches a supplementary-unit import measure to 8411 99 00 30. HMRC requires the supplementary-unit field where the commodity code requires it; ask your broker to confirm the unit and quantity for the China import declaration. Confirm the commodity code using the drawing and intended turbine. For wider heading coverage, see gas turbine combustion chambers.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other gas turbine parts, including casings where appropriate | 8411 99 00 99 | 0% | None |
| Turbojet or turbopropeller parts, including casings, other | 8411 91 00 90 | 0% | None |
| Aircraft engine parts for aircraft imported duty free or built within the Community | 8411 91 00 20 | 0% | None |
| Turbocharger turbine housings with wheel insertion holes from 28 to 181 mm | 8411 99 00 30 | 0% | None |
Specify the casing interfaces and material
Supply the turbine model, part drawing and revision, casing function, alloy grade, casting or fabrication route, heat treatment and operating conditions. Define flange flatness, bore alignment, bolt patterns, sealing grooves, wall thickness and surface finish. State whether matched casing halves, fasteners, coatings and inspection records are included.
Before selling the casing in Great Britain, ask a compliance adviser to assess its supplied form and function. Official guidance defines pressure equipment as vessels, piping, safety accessories and pressure accessories, with attached elements where applicable. Ask for a written scope assessment rather than treating a factory's generic CE certificate as acceptance evidence.
Agree material traceability, permitted repair methods and the inspection acceptance criteria before production. Use factory verification to check whether the supplier performs the casting, heat treatment and final machining itself or subcontracts them.
Worked duty example
Illustrative example, not a quote: Illustrative order: 40 small stationary gas turbine casings under 8411 99 00 99, 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 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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: check the part marking, drawing revision and material heat reference against the order and material records.
Geometry: measure flange flatness, bore alignment, bolt locations and sealing features against the approved drawing; check matched halves together.
Integrity: review the agreed non-destructive examination and heat-treatment records; inspect for cracks, porosity, unapproved weld repairs and damaged machined surfaces.
Arrival: check corrosion protection, blocked openings, internal cleanliness and transport damage before releasing the casing for assembly. Record findings using an agreed quality inspection brief.

What goes wrong
A casing can match the outside dimensions yet fail at the split line, sealing groove or mounting flange. Distortion after heat treatment, an undocumented casting repair or a material certificate that cannot be matched to the delivered part can prevent acceptance. Agree how rejected parts will be investigated and replaced.
Using a turbocharger housing description for an unrelated stationary turbine casing creates a classification mismatch. Keep the turbine application and drawing with the broker's classification record. Quarantine damaged or unidentified arrivals until the buyer's engineer has assessed them.

Frequently asked questions
What is the UK import duty on gas turbine casings from China?
The selected heading 8411 parts lines carry 0% duty in the supplied tariff record read on 4 October 2026, with no anti-dumping or countervailing duty recorded.
Which commodity code covers a stationary gas turbine casing?
8411 99 00 99 is a candidate for other gas turbine parts. Ask your broker to confirm it from the casing drawing and turbine application; the turbocharger housing line has a specific dimensional description.
Does a gas turbine casing need CE or UKCA marking?
Ask for a scope assessment for the casing as supplied. Identify its function and any pressure-equipment classification before agreeing marking or conformity documents with the factory.
What should I inspect on a gas turbine casing?
Check material traceability, drawing revision, flange flatness, bore alignment, sealing features, agreed examination records and transport damage. Inspect matched casing halves together.
