Sourcing passenger car inner tubes from China

Duty and classification

Read from the UK Trade Tariff on 30 September 2026, heading 4013 covers rubber inner tubes. Passenger car inner tubes fall under 4013 10 00 00, which also covers tubes for buses and lorries. This is the only commodity line in the supplied tariff data relevant to passenger car inner tubes.

The recorded duty for goods from China is 0%. The supplied data lists no anti-dumping or countervailing duties, suspensions or attached import controls for this line. For the wider motor-vehicle tube category, see truck inner tubes.

Give your customs broker the material, intended vehicle use and product description to confirm the commodity code. Budget separately for import VAT at 20%; see UK import duty and VAT.

Specify tyre fit, rubber and valve

List the tyre sizes and rim designs the tube is intended to fit. Agree rubber composition, tube dimensions, wall thickness, valve position, stem shape, valve core and cap. Ask for a compatibility statement for the intended assembly, including whether a rim flap is needed. Approve a sample fitted by your tyre specialist before ordering.

Consumer products supplied in Great Britain must be safe under the General Product Safety Regulations 2005. Ask the factory for batch-linked test records covering air retention, tube joints and valve attachment. Agree test conditions and acceptance criteria in writing rather than accepting an unspecified claim that the tubes are suitable for cars.

Worked duty example

Illustrative example, not a quote: Illustrative order of 2,000 passenger car inner tubes under 4013 10 00 00, invoiced at £3,500 free on board, with £2,000 of freight and insurance to the UK. The customs value is £5,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,500, so it is £1,100. 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

Fit and identification: compare tube size markings, valve position and packaging descriptions with the approved sample and intended tyre and rim assembly.

Rubber and joints: check for cracks, pinholes, contamination, uneven walls and poorly bonded joints; compare sampled dimensions with the agreed specification.

Air retention: test sampled tubes using the agreed inflation and leak-test method, checking the valve core, valve base and tube joint.

Packing and batch records: check batch identification, valve protection and carton contents; separate damaged or mixed-size stock on arrival. Use a written inspection brief.

What goes wrong

A tube can carry the expected size marking yet fit badly because its shape or valve position differs from the approved sample. A mismatched stem can rub against the rim opening, while folded or stretched rubber can be damaged during fitting. Confirm compatibility with the complete assembly.

Slow leaks may come from a loose valve core, a weak valve bond or a defective tube joint. Surface checks alone can miss them. Compare production samples with the approved sample and retain batch-linked leak-test results so complaints can be traced to the affected stock.
