Sourcing PVC electrical conduit from China

UK duty on PVC electrical conduit

Heading 3917 covers plastic tubes, pipes, hoses and their fittings. For PVC electrical conduit, distinguish rigid from flexible construction, seamless from otherwise worked rigid tube, and flexible tube with or without fittings. The table gives classification candidates for the described constructions, rather than a code assignment for every cable-protection product.

Read from the UK Trade Tariff on 30 September 2026, the selected lines carried 6% duty for goods from China, with no anti-dumping or countervailing duty, suspension or attached import control. Elsewhere in the heading, specified car fuel-hose connectors have a suspension and hardened-protein sausage casings have veterinary control. These are outside this guide; importers of those casings should confirm the control requirements with their customs broker.

Give your broker the resin specification, cross-section, manufacturing details, reinforcement and supplied fittings to confirm the commodity code. For the wider family, see insulating electrical conduit and fittings.

Specify the conduit and its installation conditions

State rigid or flexible, smooth or corrugated, resin composition, recycled content, colour, outside diameter, usable bore, wall thickness and supplied length. Agree dimensional tolerances, bend behaviour, compression and impact performance, and the intended installation temperature. Identify indoor, exposed outdoor or concealed use, and name the actual couplers, bends and boxes the conduit must fit.

REACH restrictions can limit, ban or set conditions on substances being placed on the market or used, including substances in articles. Obtain material information covering stabilisers, plasticisers and recycled feedstock, then assess applicable restrictions. Ask for test reports supporting the agreed flame behaviour and sunlight-resistance claims; match the tested formulation and conduit construction to the order.

For building use, confirm with the relevant authority whether the exact product is covered by a designated construction-product standard or a UK technical assessment before agreeing marking and documentation. Where that regime applies, ask the authority to confirm the declaration of performance, marking and importer name and address requirements for the product, including whether compliant CE-marked products are accepted in Great Britain.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 coils of unreinforced flexible PVC electrical conduit without fittings under 3917 32 00 90, invoiced at £2,400 free on board, with £1,500 of freight and insurance to the UK. The customs value is £3,900. Duty at 6% is £234. Import VAT at 20% is charged on the customs value plus duty, £4,134, so it is £826.80. Import taxes total £1,060.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £234 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Dimensions: measure outside diameter, usable bore, wall thickness around the circumference and sampled lengths against the order.

Fit: assemble the actual couplers and boxes; check insertion, retention and cable passage through the agreed bends.

Performance: compare sampled conduit with the approved sample using the agreed bend, compression and impact checks; inspect for cracks and excessive flattening.

Traceability: match batch identification, agreed markings and material reports to the shipment; count bundles or coils and check crushed sections and damaged ends.

What goes wrong

Uneven walls can leave weak sections that split during bending or handling. An undersized bore makes cable pulling difficult, while incompatible couplers leave loose joints. Corrugated conduit can flatten at tight bends. Long rigid lengths can arrive bowed or with cracked ends when bundles lack support.

A sample made from a different formulation can conceal changes in flexibility, impact behaviour or colour. Keep the approved sample and tie the material specification and test reports to the supplied batch. Repeat the agreed checks on arrival before releasing stock for installation; see quality inspection explained.
