Sourcing tractor inner tubes from China

The tariff line for tractor inner tubes

Heading 4013 covers rubber inner tubes. Tractor tubes fall within the residual description, Other, under 4013 90 00 00. The table separates purchasing applications that share this tariff line; they are not separate commodity codes. For other applications within the heading, see the motorcycle inner tubes guide.

Read from the UK Trade Tariff on 30 September 2026, the supplied record shows 0% duty for goods from China across this heading. It lists no anti-dumping or countervailing duties, suspensions or attached import controls for the tractor tube line. These tariff findings do not establish product safety.

Confirm the commodity code using the product description, material and intended vehicle application. Describe the goods as inner tubes rather than complete tyres, and keep the supplier's specification with the classification decision.

Specify tyre fit, valve geometry and rubber

Give the factory the tyre markings, rim dimensions and valve-hole details for each application. Ask it to identify the supported tyre sizes and whether the tube is suitable for radial or cross-ply construction. Approve samples fitted by a competent tyre fitter to the intended wheel assembly.

Specify rubber type, agreed wall thickness, valve stem length, bend, base position and cap. For liquid-ballasted wheels, state the filling liquid and require confirmation of tube and valve compatibility. Agree an air-retention test method and acceptance criteria before production.

UK REACH restrictions address chemical risks in articles. Ask for a compound declaration and a review of restrictions relevant to the actual materials and use. Where tubes are supplied as consumer products, businesses importing or selling them are responsible for their safety.

Worked duty example

Illustrative example, not a quote: Illustrative order: 300 tractor inner tubes, mixed sizes under 4013 90 00 00, invoiced at £2,000 free on board, with £1,500 of freight and insurance to the UK. The customs value is £3,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,500, so it is £700. 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 measured dimensions with the approved sample; trial-fit samples to the intended tyre and rim.

Valve: check stem length, bend and position, valve-core sealing and bonding at the rubber base; confirm access for inflation.

Leakage: test assembled samples using the agreed procedure, checking the joint, valve core and valve base for air loss.

Condition and identity: inspect for cracks, thin areas, trapped folds and damaged stems; match packaging and batch identification to the order. Plan these checks with the quality inspection guide.

What goes wrong

A broad size-range claim can conceal poor fit: excess tube material folds inside the tyre, while an undersized tube stretches around the valve base. An unsuitable valve bend can leave the stem rubbing against the rim or inaccessible for inflation. Catalogue descriptions alone do not settle these questions.

Weak joints, uneven walls and poor valve bonding can cause slow leaks despite an acceptable appearance. Keep an approved sample for comparison, test production samples using the agreed method and investigate failures before releasing the affected batch.
