Sourcing braided gas hoses from China

Zero duty on metal-core gas hoses

Read from the UK Trade Tariff on 30 September 2026, heading 8307 covers flexible tubing of base metal, with or without fittings. Stainless steel gas hoses with flexible metal inner tubing fall within 8307 10 00 90. The supplied tariff data lists 0% duty for China, with no trade remedies, suspensions or attached import controls for this line.

A stainless steel braid does not establish the classification. Rubber inner tubing with an external metal braid is classified under heading 4009; plastic inner tubing belongs under heading 3917. Ask for a construction drawing and confirm the commodity code. See the flexible metal hose guide for the wider heading. Only the supplied steel line is relevant to this product family.

Specify the gas duty and complete assembly

State whether the hose connects a domestic appliance or serves industrial gas pipework. Specify the gas, working pressure and temperature, inner tube and braid materials, bore, finished length, minimum bend radius, end fitting materials, thread form and sealing arrangement. Approve the complete assembly, including seals and any protective covering.

The site's published hose guide identifies BS EN 14800 for domestic gas appliance connectors and ISO 10380 for industrial corrugated metal hose assemblies. Ask for test reports that identify the actual hose construction and fittings being supplied. A report for an industrial hose is not evidence that the domestic connector specification has been met.

For Great Britain, pressure equipment rules apply above a maximum allowable pressure of 0.5 bar, subject to exclusions. Ask your compliance adviser to establish whether the intended assembly is in scope before agreeing its documentation and markings. Arrange testing and certification checks against the agreed product specification.

Worked duty example

Illustrative example, not a quote: Illustrative small-business batch of stainless steel braided gas hoses in assorted lengths under 8307 10 00 90, invoiced at £2,500 free on board, with £810 of freight and insurance to the UK. The customs value is £3,310. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,310, so it is £662. 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

Construction: compare the inner tube, braid, end fittings and seals with the approved drawing and material records; inspect welds, broken braid wires and corrosion.

Fit: measure finished length and bore, gauge fitting threads, and check sealing faces and nut movement against the approved assembly.

Performance: review batch leak and pressure test records; agree qualified testing of bending and fitting retention against the applicable specification.

Traceability: match hose identifiers, packaging and test reports to the delivered batch. Check instructions describe the intended gas and installation arrangement. Use the quality inspection guide to brief the inspector.

What goes wrong

The braid can conceal a substituted inner tube. Thin corrugations can crack when bent too tightly, braid wires can corrode, and poorly attached end fittings can leak or pull away. Wrong threads or sealing faces can make a hose unsuitable even when its overall length matches.

A sample can pass while production uses different fittings, seals or welding settings. Agree the construction and acceptance tests before ordering, then compare the delivered batch with the approved sample and its records. Hold suspect assemblies for investigation rather than trying to resolve a gas leak by tightening an incompatible fitting.
