Sourcing railway brake blocks from China

Duty and classification for railway brake blocks

Read from the UK Trade Tariff on 30 September 2026, heading 8607 covers railway and tramway rolling stock parts, including brakes and their parts. The listed brake lines carry 0% duty from China, with no anti-dumping or countervailing duty and no suspension recorded. The table distinguishes cast iron, cast steel and other air brake parts from other brake parts; it does not establish the classification of every brake block.

The UK Trade Tariff attaches a restriction on entry into free circulation relating to ozone-depleting substances to these brake lines. Confirm the applicable declaration with your customs broker. The extract also lists a DCMS Export Licence measure; ask the broker to confirm its relevance to the intended movement rather than treating it as an import licence.

Give your broker the material composition, drawing, mounting arrangement and intended brake system to confirm the commodity code. For other parts in this heading, see the railway rolling stock parts guide.

Specify the brake block and its wheel interface

State whether you need cast iron or composite blocks, the vehicle application, wheel tread profile, block curvature, mounting slot and retaining arrangement. Supply the controlled drawing and identify its revision. Agree the friction performance, wear behaviour and wheel compatibility that the railway buyer will accept, together with the test evidence needed for that exact material and design.

Confirm with the relevant authority whether the blocks are interoperability constituents and which conformity assessment requirements apply, and ask tram and heritage railway buyers about their approval requirements. Establish the applicable acceptance route with the buyer before production. Ask for material declarations and asbestos test evidence where appropriate. HSE states that placing vehicle parts containing asbestos on the market is strictly prohibited, including parts for heritage vehicles.

Worked duty example

Illustrative example, not a quote: 40 vehicle sets of railway brake blocks, illustrative only under 8607 29 00 00, invoiced at £32,000 free on board, with £6,000 of freight and insurance to the UK. The customs value is £38,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £38,000, so it is £7,600. 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

Fit: measure curvature, length, thickness, mounting slots and retaining features against the agreed drawing; check a sample in the intended holder.

Material: match cast material or composite formulation to the purchase specification and review the corresponding material and performance reports.

Traceability: match block markings and carton labels to production batches, material records and inspection reports; check that different formulations are kept separate.

Arrival condition: inspect for cracks, chipped friction surfaces, loose inserts, corrosion and moisture damage before releasing stock for fitting.

What goes wrong

A block can fit its holder yet have the wrong curvature or friction behaviour for the wheel and brake system. Substituting a composite formulation or backing arrangement after sample approval can invalidate the buyer's acceptance evidence. Freeze the material and drawing in the order, and require approval before changes.

Mixed batches and reports that describe a different block make defects difficult to trace. Keep rejected stock separate and ask the factory to link its investigation to the affected batch. Agree the checks and reporting format through quality inspection before dispatch.
