Sourcing gas turbine nozzle rings from China
Gas turbine nozzle rings from China carry 0% UK duty across the relevant parts lines of heading 8411. Choose the code from the turbine type and exact part description. Suppliers must supply safe work equipment; agree alloy, geometry and inspection evidence before ordering. Cambridge China Bridge sources gas turbine nozzle rings.
Nozzle-ring parts lines carry 0% duty
Heading 8411 covers turbojets, turbopropellers and other gas turbines, including their parts. Nozzle rings are stationary components that guide gas towards the rotor blades. Distinguish a complete ring from separate ring segments, and identify the turbine it fits. See the related gas turbine stator vanes guide for wider parts sourcing.
Read from the UK Trade Tariff on 4 October 2026, the selected parts lines carried 0% duty for goods from China. The supplied tariff extract records no anti-dumping or countervailing duties, suspensions or attached import controls for these lines. This duty snapshot does not establish that a ring is suitable for installation.
The ring-segment line has specific alloy, operating-temperature and dimensional conditions; a complete nozzle ring does not qualify merely because it uses a nickel alloy. The aircraft-use line also has a specific intended-use description. Give your customs broker the drawing, material specification and turbine application, then confirm the commodity code.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Turbojet or turbopropeller parts meeting the specified aircraft-use description | 8411 91 00 20 | 0% | None |
| Other turbojet or turbopropeller parts | 8411 91 00 90 | 0% | None |
| Stationary turbine ring segments meeting the alloy, temperature and size description | 8411 99 00 45 | 0% | None |
| Other gas turbine parts, including nozzle rings where this description applies | 8411 99 00 99 | 0% | None |
Specify the nozzle geometry and material history
State the turbine model, part identity, drawing revision, stage position and whether you need a complete ring or matched segments. Specify mounting datums, inner and outer diameters, vane profile and angle, throat area, seal interfaces and segment joints. For cooled designs, define passage geometry and cooling-hole positions.
Agree the alloy, casting route, heat treatment, coating system and finished inspection criteria. Request material certificates linked to the casting batch, dimensional reports and agreed crack-detection results. Record whether the parts are new or refurbished, and require written approval for repair welds or material substitutions.
For workplace supply, HSE states that suppliers must supply safe work equipment, and its guidance includes adequate information for safe use and maintenance. Request installation, handling and maintenance information relevant to the ring and its intended turbine. Use factory verification to check the proposed casting, machining and inspection processes.
Worked duty example
Illustrative example, not a quote: 20 industrial gas turbine nozzle rings; illustrative order under 8411 99 00 99, invoiced at £28,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £29,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £29,200, so it is £5,840. 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 delivered ring, drawing revision and batch identification to the order and material records.
Geometry: measure mounting faces, concentricity, vane angles, throat openings and segment joints against the agreed drawing.
Material and surface: check alloy and heat-treatment records, agreed crack-detection results, coating condition and cooling passages for blockage.
Arrival condition: inspect for distorted rings, chipped vane edges, coating damage and loose debris before release for installation. Agree protective packing and the scope of quality inspection.

What goes wrong
A ring can fit the casing yet have the wrong vane angle or throat area, changing gas flow through the turbine. Distortion after heat treatment can prevent correct seating; coating build-up can obstruct cooling holes. Material substitutions and certificates that cannot be linked to the delivered batch leave the buyer unable to verify the agreed specification.
Set acceptance criteria before production and ask the turbine engineer to review the sample and inspection reports. Keep suspect arrivals separate while discrepancies are investigated. Avoid accepting a dimensional check alone as evidence of material condition or service suitability.

Frequently asked questions
What is the UK import duty on gas turbine nozzle rings from China?
The relevant heading 8411 parts lines carried 0% duty on 4 October 2026, with no anti-dumping or countervailing duties recorded in the supplied tariff extract.
Which commodity code covers a gas turbine nozzle ring?
It depends on the turbine and part description. Check whether the goods are turbojet or turbopropeller parts, qualifying stationary turbine ring segments, or other gas turbine parts.
What should I ask a Chinese nozzle-ring factory for?
Request the drawing revision, alloy and heat-treatment specification, batch-linked material certificates, dimensional report, coating details and agreed crack-detection results.
Can I approve a nozzle ring just because it fits?
Fit alone does not verify vane geometry, alloy, heat treatment or cooling passages. Have the turbine engineer review the agreed inspection evidence before installation.
