Sourcing ship rudder trunks from China
Ship rudder trunks from China carry 0% UK duty across the selected heading 8487 lines, provided classification here is correct. This residual heading does not cover every marine component. Specify the vessel drawing, material and bearing interfaces before ordering. Cambridge China Bridge sources ship rudder trunks.
Zero duty on the selected material lines
Heading 8487 covers machinery parts without electrical features that are not specified elsewhere in the chapter. For rudder trunks, the selected rows are candidate material-based lines, rather than dedicated rudder-trunk codes. Their inclusion does not establish that a material is suitable for your vessel.
Read from the UK Trade Tariff on 1 October 2026, all selected lines carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duties, suspensions, steel measures or attached import controls for these lines.
Confirm the commodity code using the drawing, material, manufacturing process and supplied assembly. Heading 8487 is residual: identifiable machine parts and separately specified components may belong elsewhere. For the wider product family, see ship rudder assemblies.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cast-steel rudder trunks, subject to classification | 8487 90 51 90 | 0% | None |
| Forged iron or steel rudder trunks, subject to classification | 8487 90 57 90 | 0% | None |
| Other iron or steel rudder trunks, including fabricated versions | 8487 90 59 90 | 0% | None |
| Rudder trunks of other materials, subject to classification | 8487 90 90 90 | 0% | None |
Specify the trunk and its vessel interfaces
Define the casing around the rudder stock, its hull connection and the exact supply boundary. State whether bearing bushes, gland housing, seals and attachment flanges are included. Provide drawing revisions, material grade, wall thickness, machining allowance, bearing-seat dimensions, bore alignment, flange orientation and coating requirements.
Agree material certificates, heat treatment records and a dimensional report before production. Specify weld preparation, examination methods and acceptance criteria for fabricated trunks. Ask the vessel designer or surveyor to confirm the intended approval route. Official guidance requires UK approval for marine equipment within the applicable UK ship approval scheme; confirm whether your supply falls within its scope.
Worked duty example
Illustrative example, not a quote: 40 fabricated steel rudder trunks for a boatyard repair programme, illustrative under 8487 90 59 90, invoiced at £27,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £29,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £29,000, so it is £5,800. 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
Material: match component identification to material certificates and the ordered grade; review casting or forging examination records where specified.
Geometry: measure bearing seats, bore alignment, flange faces and attachment positions against the vessel drawing; repeat critical checks on arrival.
Welds and sealing: review examination reports and inspect accessible welds; verify gland interfaces and any agreed watertightness test records.
Packing: check bore protection, supports and corrosion protection before dispatch and on arrival. Solid wood packaging must meet import requirements; make the exporter responsible for checking it before shipment.

What goes wrong
Welding distortion can move bearing seats out of alignment, while machining from inconsistent datums leaves flanges and bores mismatched. Porosity, incomplete weld fusion or damaged gland faces can compromise the intended sealing arrangement. A drawing that omits the hull connection leaves the yard to resolve fit during installation.
Approve the inspection plan before manufacture and hold components with missing traceability or failed critical dimensions for review. Do not accept coating as evidence of sound welds. Record transit damage and inspect protected machined surfaces before releasing the trunks for installation.

Frequently asked questions
What is the UK import duty on ship rudder trunks from China?
The selected heading 8487 lines carry 0% duty from China in the supplied tariff record. Confirm the material-based code and whether the trunk belongs in this residual heading.
Are ship rudder trunks always classified under 8487?
No. Heading 8487 is residual. Use the drawing, material, manufacturing process and assembly details to confirm classification before ordering.
What should I specify for a rudder trunk?
Specify the vessel drawing revision, material, hull connection, bearing seats, bore alignment, gland interfaces and included components. Agree weld examination and inspection records.
Does zero import duty mean the trunk is approved for installation?
Confirm the intended approval route separately with the vessel designer or surveyor. Check whether the supply falls within the UK marine equipment approval scheme.
