Sourcing bicycle inner tubes from China

Bicycle inner-tube duty and classification

Read from the UK Trade Tariff on 30 September 2026, heading 4013 covers rubber inner tubes. Bicycle inner tubes fall under 4013 20 00 00 and carry 0% duty on goods from China. The table shows product variants sharing this single bicycle commodity line.

The supplied tariff facts record no anti-dumping or countervailing duty, suspensions or attached import controls for the bicycle line. The safety guidance below concerns sales in Great Britain: general product safety rules require safe consumer products.

Confirm the material and bicycle use from the supplier's specification before selecting the commodity code. For another product family within this heading, see motorcycle inner tubes.

Specify tyre fit, rubber and valves

Give the factory the tyre's marked size and intended width range, rather than a wheel nickname alone. Specify butyl or latex rubber, tube weight and wall thickness, valve type, valve length, stem angle and whether the valve core is removable. Approve the valve against the actual rim hole and rim depth.

Agree how the factory will check seams, valve bonding and air retention, including the inflation method and acceptance criteria. Use a fitted tyre and wheel for the functional trial. Specify retail size markings, fitting information and protective packing around the valve stem.

For Great Britain, the legal baseline is a safe consumer product. Keep records identifying your suppliers so the goods' origins can be traced. Retain the approved sample, specification and inspection results alongside those records.

Worked duty example

Illustrative example, not a quote: Illustrative order: 1,200 bicycle inner tubes; FOB and freight values are illustrative under 4013 20 00 00, invoiced at £2,000 free on board, with £910 of freight and insurance to the UK. The customs value is £2,910. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £2,910, so it is £582. 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 tube and pack size markings with the order, then fit samples into the intended tyre and rim. Check valve access for the intended pump.

Valves: check stem length, straightness, threads and core operation. Look for leaks at the valve and separation around its rubber base.

Rubber and seams: compare weight and wall thickness with the approved sample. Inspect for thin patches, cracks, contamination and uneven seam joints.

Air retention and packing: test samples using the agreed method, recording pressure and test conditions. Check that packing protects valve stems and keeps different sizes identifiable. See quality inspection explained.

What goes wrong

A tube can match the carton description yet have a valve too short for the rim, an unsuitable width range or a leaking valve core. Thin patches, weak seams and poor valve bonding can cause air loss. Test the fitted assembly as well as inspecting the loose tube.

A replacement rubber formulation or valve supplier can change performance after sample approval. Record the approved construction and require agreement before substitutions. Keep suspect batches separate while investigating leaks or fit complaints.
