Sourcing ATV inner tubes from China

Duty and classification for ATV inner tubes

Read from the UK Trade Tariff on 30 September 2026, heading 4013 covers rubber inner tubes. The relevant candidate for ATV inner tubes is 4013 90 00 00, described as other. The table shows buying variants sharing this code, rather than separate tariff lines.

The supplied tariff facts show 0% duty on goods from China throughout this heading. For the other inner-tube line, no anti-dumping or countervailing duty, suspension or attached import control is listed. These findings concern the rubber inner tube supplied separately.

Give your customs broker the intended vehicle application, material description and product photographs to confirm the classification. See finding your commodity code. For the wider heading, see motorcycle inner tubes.

Specify tyre fit, rim fit and valve clearance

Specify the tyre size designation, rim diameter and width, front or rear application, and whether the tyre and rim arrangement is intended to use a tube. Provide photographs of the valve hole and surrounding clearance. Agree valve shape, stem length, orientation and attachment construction against an approved sample.

Name the rubber compound, agreed wall thickness and tolerances, seam construction and air-retention acceptance criteria. Ask the factory to identify the sizes covered by each tube rather than accepting an unrestricted compatibility claim. Trial samples in the intended tyre and rim assembly.

For consumer sales in Great Britain, the general product safety requirement is to supply safe products. Support your buying decision with documented fit trials and leak-test results. Agree fitting information covering valve alignment, trapped folds and checks for damage inside the tyre.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2,000 ATV inner tubes under 4013 90 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: compare size markings and relaxed dimensions with the approved sample, then trial the tube in the intended tyre and rim.

Valve: check stem shape, orientation, valve-core sealing and clearance; inspect the rubber-to-valve bond for cracks or lifting.

Air retention: inflate samples using an agreed test method, check for bubbles at seams and valves, and record pressure loss over the agreed holding period.

Condition and packing: inspect for thin areas, split seams, contamination and creased rubber; match product and carton identification to the purchase order.

What goes wrong

A tube can match the advertised tyre size yet bunch inside the casing or pull the valve sideways. A bent valve pointing the wrong way can contact the wheel or prevent access for inflation. Over-broad size claims and substituted valve designs are reasons to repeat the fitting trial before accepting a batch.

Slow leaks can come from valve cores, seam defects or weak valve bonds. Installation damage can resemble a manufacturing defect, so retain failed tubes and fitting records for investigation. Agree defect photographs, batch identification and acceptance criteria before shipment; see quality inspection explained.
