Sourcing Nitrile Rubber Sheets from China

UK duty on nitrile rubber sheets

Heading 4008 covers plates, sheets, strip, rods and profiles of vulcanised rubber other than hard rubber. Solid nitrile sheet and strip normally fall under 4008 21 90 00; cellular sheet and strip have a separate line, as do solid floor coverings and mats. Finished cut gaskets and seals fall under heading 4016.

Read from the UK Trade Tariff on 1 October 2026, the listed lines carried 2% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls. The duty range is therefore a single rate for these lines.

Confirm the form and intended use through finding your commodity code. For the wider heading, see solid neoprene rubber sheets. The hypothetical order values are illustrative; see UK import duty and VAT for the calculation method.

Specify the nitrile compound and oil exposure

State whether the sheet is solid or cellular, the compound formulation, permitted recycled content, hardness, thickness, width, surface finish and tolerances. Describe the actual oil or fuel, working temperature and sealing conditions. Agree oil-swell acceptance criteria using ISO 1817, rather than accepting an unsupported oil-resistant description.

Specify hardness to ISO 48-4, tensile strength and elongation to ISO 37, and compression set to ISO 815-1 where sealing performance matters. Tie the approved sample and test reports to the production compound and batch.

UK REACH restrictions can limit, ban or set conditions on placing substances on the market or using them. For rubber parts in articles with prolonged or repeated skin contact, confirm with HSE whether the PAH restrictions in entry 50 apply. For food-contact grades, confirm the applicable food-contact requirements and supporting evidence with the relevant food safety authority; an oil-resistance report does not establish food-contact suitability.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of solid nitrile rubber sheet under 4008 21 90 00, invoiced at £40,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £43,000. Duty at 2% is £860. Import VAT at 20% is charged on the customs value plus duty, £43,860, so it is £8,772. Import taxes total £9,632; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £860 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Compound: compare batch identification, hardness, tensile strength, elongation and density with the approved specification.

Oil resistance: test production samples against the agreed fluid and conditions, recording swelling and changes in physical properties.

Dimensions: measure thickness across the width and along each roll; check width, usable length and agreed tolerances.

Condition: inspect for cracks, voids, bloom, strong odour, damaged edges and telescoping rolls; obtain applicable skin-contact test evidence.

What goes wrong

A substituted polymer or excessive filler can meet a hardness target while failing oil resistance, tensile strength or sealing performance. Accepting a sample without tying it to the production formulation leaves the buyer exposed to a different compound in the shipment.

Uneven thickness causes inconsistent gasket compression, while bloom, voids and damaged roll edges reduce usable material. Compare arrival samples with retained approved samples and batch reports before cutting the sheets into parts.
