A flat 6%

Read from the UK Trade Tariff on 25 September 2026, monofilament with a cross-section over 1 mm, rods, sticks and profile shapes of polyethylene, PVC and other plastics carried 6% duty on goods from China, with no anti-dumping measure.

Assembled windows and doors are in heading 3925, and tubes and hoses in 3917; confirm the commodity code.

Windows and standards

Unplasticised PVC profiles for windows and doors are specified to BS EN 12608, which classifies wall thickness, weathering and impact performance. The profile is a component: the fabricated window must meet the Building Regulations for thermal performance and, where required, security, and windows are construction products where a designated standard applies. Ask the extruder for the BS EN 12608 test report and the reinforcement specification.

Worked duty example

Illustrative example, not a quote: 5,000 metres of PVC window profile under 3916 20 00 99, invoiced at £8,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £9,500. Duty at 6% is £570. Import VAT at 20% is charged on the customs value plus duty, £10,070, so it is £2,014. Import taxes total £2,584; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £570 of duty. The import duty and VAT guide explains each step.

What goes wrong

Profiles fail through the formulation. Too little UV stabiliser or cheap filler makes white profile yellow and chalk outdoors, and thin walls crack at welded corners in cold weather. Colour-foiled profiles delaminate if the adhesive is wrong. Dimensions drift between batches, so gaskets and hardware stop fitting.

At inspection, measure wall thickness and chamber dimensions against the drawing, test a welded corner, check colour against the approved sample and protective film, and confirm lengths and bundling.
