Sourcing gas turbine rotor blades from China

0% duty, with classification tied to the turbine

Heading 8411 covers turbojets, turbopropellers and other gas turbines, including their parts. Rotor blades need a parts code matched to their application. Stationary gas turbine blades and turbojet or turboprop engine blades have different lines; a description such as ‘turbine spare’ is insufficient for checking the classification.

Read from the UK Trade Tariff on 4 October 2026, the supplied tariff snapshot records 0% duty for goods from China on every selected line. It lists no anti-dumping or countervailing duty, suspensions or attached import controls for these lines. This describes the supplied snapshot; check the entry again before shipment.

For 8411 99 00 45, the tariff description specifies nickel-based superalloys, an operating temperature above 600 K and not above 1600 K, and maximum length, width and height of 500 mm, 900 mm and 1300 mm respectively. Give your broker the drawing, material specification and intended turbine use to confirm the commodity code. For the wider heading, see gas turbine combustion chambers. For compressor parts, see our guide to sourcing gas turbine compressor blades.

Specify the blade root, alloy and cooling design

Provide the turbine model, blade stage, part identity and drawing revision. Specify the root profile, aerofoil geometry, tip and shroud arrangement, cooling passages, alloy, casting structure, heat treatment and coating system. Agree dimensional acceptance criteria and the inspection methods before production. Ask for material and process records linked to the actual batch.

Goods supplied for use at work must be safe, so far as reasonably practicable, and accompanied by adequate information for safe use. Agree what installation, handling and maintenance information accompanies the blades. Where relevant product supply legislation applies, appropriate conformity marking and documentation are required; ask a compliance specialist to assess the particular supply.

For aircraft-engine blades intended for installation in a type-certificated product, HMRC guidance states that the part must be accompanied by an authorised release certificate or an equivalent certificate. Ask the intended maintenance organisation to review the proposed release paperwork before ordering. Keep this review separate from the commercial drawing and material inspection.

Worked duty example

Illustrative example, not a quote: Illustrative order: 40 stationary gas turbine rotor blades under 8411 99 00 45, 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: match blade markings, drawing revision, batch records and carton contents to the purchase order; keep batches distinguishable.

Geometry: check root fit, aerofoil profile, twist, tip, shroud and cooling-hole positions against the approved drawing and inspection plan.

Material and surface: match alloy, heat-treatment and coating records to the batch; review agreed crack and internal-defect inspection results.

Arrival condition: check for edge damage, coating chips, corrosion, blocked cooling passages and contact between blades in transit. Record findings through quality inspection.

What goes wrong

A blade can resemble the sample while having a different root profile, cooling pattern or coating system. A generic alloy certificate can also conceal a missing link to the delivered batch. Resolve drawing revisions and record traceability before accepting the goods; visual checks alone cannot establish compliance with the agreed material specification.

Unapproved weld repair, blending or coating rework can leave the buyer with a blade whose production history is unclear. Require the supplier to disclose proposed repairs and obtain written technical acceptance before proceeding. On arrival, separate damaged or unidentified blades from stock awaiting installation.
