Sourcing woven weatherstrip pile fabric from China

UK duty on woven weatherstrip pile fabric

Read from the UK Trade Tariff on 30 September 2026, the supplied heading 5801 lines cover woven pile fabrics and chenille fabrics. This guide focuses on pile fabric supplied for making door and window weatherstrips. The table gives possible fabric classifications by fibre and pile construction, rather than assigning a code to every finished seal. See the wider pile fabric guide.

All supplied lines carry 8% duty for goods from China. No anti-dumping duty, countervailing duty or tariff suspension is recorded. No import controls are recorded for the table rows. CITES import controls appear on the wool or fine animal hair and residual other-material lines; CITES export controls also appear on wool, silk, ramie and residual other materials. CITES-covered specimens from China need an import permit. Confirm species-specific requirements with your customs broker.

Confirm the commodity code using the fibre composition, weave, width, edge construction, backing and condition as shipped. Ask the broker to review narrow strips, coated fabric and finished seals separately rather than relying on the supplier's weatherstrip description.

Specify the pile, backing and mating channel

State whether you need fabric rolls for conversion or finished weatherstrip strips. Specify pile yarn, ground fabric, cut or loop pile, pile height and density, usable width, backing thickness, colour and pile direction. For finished samples, describe any adhesive, backing reinforcement or sealing fin and supply the actual channel profile.

Agree tolerances against a retained sample and drawing. Test the converted sample in the intended window or door: it should remain seated, contact the mating surface and allow movement without excessive drag. Agree checks for pile recovery, shedding, backing separation and exposure to moisture and sunlight.

UK REACH generally applies to substances in articles, and chemical restrictions can apply to article materials. Ask the factory to identify yarn treatments, dyes, backing coatings and adhesives, then review applicable restrictions for the intended use. Arrange testing and certification against the actual supplied construction.

Worked duty example

Illustrative example, not a quote: Illustrative order: 3,000 metres of polyester warp pile fabric for weatherstrip manufacture under 5801 37 00 00, invoiced at £6,000 free on board, with £400 of freight and insurance to the UK. The customs value is £6,400. Duty at 8% is £512. Import VAT at 20% is charged on the customs value plus duty, £6,912, so it is £1,382.40. Import taxes total £1,894.40; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £512 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Dimensions: measure usable fabric width, pile height and backing thickness against the drawing; check variation across and along the roll.

Pile: look for sparse areas, uneven cutting and flattened bands; rub and compress samples, then check shedding and recovery.

Backing: inspect for cracks, loose yarns and separation; convert a sample using your cutting and bonding process and inspect the edges.

Fit and packing: trial the converted strip in the mating channel, check retention and sliding resistance, and inspect rolls for dampness and crushed pile. Use the quality inspection guide to brief the inspector.

What goes wrong

A sample can look correct while the converted strip performs poorly. Pile that is too short leaves gaps; excessive pile height or stiffness increases sliding resistance. An unsuitable backing can pull out of the channel, curl after cutting or separate during bonding.

Roll compression can flatten the pile before installation, while changes in yarn or backing can alter recovery and fit between batches. Keep the approved fabric and converted seal samples together, record material changes and repeat the channel trial on production samples.
