Sourcing concrete cable troughs from China

Zero duty, with classification confirmed

Heading 6810 covers articles of cement, concrete or artificial stone, whether reinforced or unreinforced. For cable troughs and covers, assess the prefabricated structural-component line against the other-articles line. The table separates trough bodies and covers within these possible classifications; it does not establish a final code for your design.

Read from the UK Trade Tariff on 30 September 2026, all supplied heading 6810 lines carry 0% duty for goods from China. The supplied data records no anti-dumping or countervailing measures, suspensions or attached import controls. Import VAT is separate from customs duty.

Give your customs broker the material specification, drawings, reinforcement details and intended installation, then confirm the commodity code before shipment.

Trough geometry, cover seating and load evidence

Specify internal cable space, external dimensions, wall and base thickness, joint profile, bends, junctions and drainage openings. Set dimensional tolerances on the approved drawing. Agree whether covers must support pedestrians, maintenance equipment or vehicles, and ask for test evidence matching the proposed trough-and-cover assembly and support arrangement.

For a CE route, a construction product must be covered by a harmonised European standard or have a European Technical Assessment before it can be CE marked. CE marking continues to be recognised for construction products in Great Britain. Confirm coverage for the actual design and intended use, rather than accepting a certificate for a different drainage product.

Agree reinforcement layout, concrete performance, lifting arrangements, unit weights and packing supports with the factory. Trial-assemble production samples with their covers before approving the order.

Worked duty example

Illustrative example, not a quote: Illustrative order of 60 precast concrete cable trough sections with matching covers under 6810 91 00 00, invoiced at £15,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £18,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £18,000, so it is £3,600. 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

Geometry: measure cable space, wall thickness, joint alignment and cover seating against the approved drawing; assemble adjacent sections and check that covers sit without rocking.

Concrete and reinforcement: inspect for cracks, honeycombing, exposed reinforcement and damaged lifting points; compare production records and test reports with the agreed specification.

Cover performance: check cover identity, bearing surfaces and the load-test report against the supplied assembly, including its support conditions.

Packing and arrival: check separators, edge protection, stack supports and restraint at inspection; photograph cracks and chipped seating edges before unloading and compare delivered quantities with the packing list.

What goes wrong

Troughs can arrive intact but fail to assemble because joints differ between moulds or covers do not match the seating rebate. Chipped bearing edges make covers rock, while poorly supported stacks can crack bases during transport. Approve an assembled sample and record packing supports before shipment.

A report for a cover alone does not demonstrate the performance of the complete installed assembly. Settle the support arrangement and intended loading before choosing the design, and check that reports identify the product being supplied.
