Sourcing aircraft inner tubes from China

Duty and classification

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

The supplied facts contain only one commodity line relevant to aircraft inner tubes, so the table contains that line. The wider heading is discussed in our motorcycle inner tubes guide. Confirm the commodity code with your broker using the material, product description and intended use.

HMRC says that claiming airworthiness customs relief requires the appropriate certificate to be held and declared. The ordinary duty in the supplied record is already 0%; ask your broker whether a relief claim serves any purpose for your shipment. Separately, agree the documents for the intended aircraft installation with the maintenance organisation.

Specify the tube, tyre and wheel together

Give the factory the aircraft application, tube manufacturer's part number, tyre size and wheel details. Specify valve type, stem angle, length and position, together with the rubber compound and any agreed storage-life conditions. Have the maintenance organisation review a proposed substitute before ordering; matching the nominal tyre size alone is a poor basis for choosing a tube.

Ask for a sample, dimensional drawing, batch identification and the proposed supporting documents. Agree air-retention testing and acceptance criteria with the maintenance organisation rather than choosing a generic road-tube test. Record the approved sample and document set in the purchase specification.

Worked duty example

Illustrative example, not a quote: 1,200 aircraft inner tubes for a distributor's stock order, illustrative only under 4013 90 00 00, invoiced at £40,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £42,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £42,000, so it is £8,400. 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

Identity: match tube and packaging markings, part number and batch identification against the order and supporting documents.

Valve fit: compare stem angle, length, position and valve-base construction with the approved drawing; arrange a fit check in the intended wheel.

Rubber condition: inspect for cracks, cuts, contamination, damaged folds and uneven joints, including the area around the valve base.

Air retention: obtain batch test records and arrange sample testing using the agreed method; check for leakage at the valve core, valve base and tube body. See quality inspection explained.

What goes wrong

A nominally matching tube can have a valve that fouls the wheel or sits under strain. Incorrect dimensions can leave folds or stretch the rubber. Leakage can arise at a damaged valve base, a poor joint or a puncture caused during packing. Set aside affected stock and ask the maintenance organisation to assess it before installation.

Documents can describe a different part or batch from the delivered goods. Check identifiers before shipment and again on arrival, and keep mixed batches separate. Do not accept a supplier's general aviation claim as your purchasing specification.
