Sourcing wheelchair inner tubes from China

Wheelchair inner tube duty

Read from the UK Trade Tariff on 30 September 2026, heading 4013 covers rubber inner tubes. The other inner tubes line, 4013 90 00 00, carries 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls.

The table shows wheelchair applications sharing the same other inner tubes line, rather than separate tariff subdivisions. Confirm the classification from the product description and intended use with your broker using finding your commodity code. For the wider heading, see bicycle inner tubes.

Specify tyre fit and valve clearance

Specify the compatible tyre and rim, tube size range, rubber compound, wall thickness tolerance, valve type, stem length and angle. Send photographs of the rim hole and access around the wheel. Agree air-retention testing, packing and batch identification. Approve a sample fitted to the intended wheelchair wheel, including access for the user's pump.

For Great Britain, MHRA guidance says replacement parts for an already UKCA-marked medical device are usually not medical devices unless they are likely to significantly change its characteristics or performance. Accessories are classified separately as medical devices. Ask the supplier to document the tube's intended use and confirm which description applies before ordering.

Businesses importing or selling consumer products are responsible for ensuring they are safe for consumers. Keep compatibility information, fitting instructions and test results with the approved sample. Use testing and certification support to agree evidence appropriate to the intended product.

Worked duty example

Illustrative example, not a quote: Illustrative order of 1,200 wheelchair inner tubes under 4013 90 00 00, invoiced at £3,500 free on board, with £910 of freight and insurance to the UK. The customs value is £4,410. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,410, so it is £882. 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 the tube and packaging size with the approved specification, then fit samples to the intended tyre and rim without folds or trapped rubber.

Valve: check stem length, angle, rim-hole fit and clearance from spokes or wheel components. Connect the intended pump and check the valve core and base for leaks.

Air retention: test inflated samples using the agreed pressure and duration. Inspect joints and valve bases for bubbles, weak bonding, cracks or local thinning.

Packing: check caps, size labels and batch identification against the order. Inspect for crushed stems, sticky rubber or damaged packaging on arrival. See quality inspection explained.

What goes wrong

A matching nominal tyre size can conceal the wrong tube width or valve geometry. The tube may fold inside the tyre, the valve may rub against the rim, or the pump may not reach it. Slow leakage can come from the valve core, the valve-base bond or the tube joint.

Approve the assembled wheel rather than an unmounted tube alone. Record the approved valve geometry and test method, and compare incoming batches with that sample. Quarantine leaking or visibly damaged stock while the supplier investigates the cause.
