Sourcing fibre-cement cable ducts from China

Duty and the asbestos restriction

Read from the UK Trade Tariff on 1 October 2026, heading 6811 covers articles of asbestos-cement, cellulose fibre-cement or similar materials. For asbestos-free cable ducts, check the other-articles line, 6811 89 00 00. The table includes the other heading lines for classification context; they are not alternative descriptions of tubular ducts.

All supplied lines carry 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls. This does not replace UK REACH checks: ask HSE to confirm the restrictions on new articles with intentionally added asbestos. Placing on the market includes import.

Give your customs broker the material composition, cross-section, drawings and intended use to confirm the commodity code. For the wider product family, see cellulose fibre-cement pipes.

Specify the bore, joints and installation

Specify an asbestos-free fibre-cement composition, internal bore, wall thickness, length, straightness and dimensional tolerances. Identify whether the route uses closed tubes or open troughs with removable covers. Draw the joint profile and list couplings, bends and end pieces. Agree smooth internal surfaces and joint alignment so cable pulling does not meet sharp lips.

Describe burial or exposed installation, support spacing, expected loading and the cable-pulling method. Ask for strength and joint-fit test evidence for the supplied design. For permanent installation, ask a compliance adviser to confirm the applicable standard, documentation and marking route. Government guidance says products not covered or fully covered by a designated standard may be covered by a technical assessment document. Use testing and certification support to define the evidence before ordering.

Worked duty example

Illustrative example, not a quote: Illustrative palletised batch of asbestos-free fibre-cement cable ducts and couplings under 6811 89 00 00, invoiced at £9,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £11,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £11,500, so it is £2,300. 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

Composition: check the asbestos-free order clause, material declaration and laboratory report against the supplied production batch.

Dimensions: measure bore, wall thickness, length and straightness against the approved drawing; check that the duct remains clear along its length.

Joints: assemble ducts with the supplied couplings and bends; check alignment, insertion fit and internal edges that could snag a cable.

Arrival condition: inspect for cracks, chipped ends, damaged joint faces and crushed packing; record batch identities and photograph damage before installation. Agree sampling through the quality inspection guide.

What goes wrong

A matching outside diameter can hide a smaller bore or thicker wall, while mismatched couplings leave steps inside the cable route. Rough internal faces can snag cable jackets. Poor curing, inadequate support during transport and unprotected ends can leave ducts cracked before installation. Approve an assembled sample and agree packing that supports the lengths and protects joint faces.

A report for boards or another duct design does not demonstrate the ordered duct's performance. Supplier material substitutions can also undermine the asbestos-free specification. Keep the drawing, composition, batch report and inspection record together, and hold damaged or suspect goods apart while the supplier resolves the issue.
