Sourcing twin welding hoses from China

Duty on twin welding hoses

Read from the UK Trade Tariff on 1 October 2026, heading 4009 covers tubes, pipes and hoses of vulcanised rubber other than hard rubber, with or without fittings. For twin oxygen-acetylene welding hoses, classification depends on reinforcement material and whether fittings are supplied.

The relevant lines carry 2% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls for these lines. The suspension for a specifically described automotive brake hose does not cover twin welding hoses.

Confirm the construction and fittings with your broker using finding your commodity code. The rubber compressed-air hoses guide provides wider heading context; an air-hose description is not evidence of oxygen or acetylene suitability.

Specify each gas passage and its fittings

State oxygen and acetylene service separately, bore and outside diameter, reinforcement, working pressure, coil or assembly length, and whether the joined hoses can be separated at the ends. Agree the identification colours, marking, batch traceability and packing. For assemblies, supply drawings of the regulator and torch connections, including thread direction, sealing face and crimp details.

HSE advises using hoses designed for acetylene and oxygen respectively, marked and manufactured to the correct standards. Ask for the applicable gas-hose standard and test reports covering the actual construction ordered, rather than accepting a compressed-air hose report. Agree leak, pressure and fitting-retention checks with a competent test provider through testing and certification.

Businesses supplying workplace products are responsible for meeting their legal obligations. Before selling, establish which product safety requirements apply to the hose or assembly and obtain the supporting documents and safe-use instructions.

Worked duty example

Illustrative example, not a quote: Illustrative small-business order of textile-reinforced twin welding hose coils under 4009 31 00 90, invoiced at £3,000 free on board, with £1,260 of freight and insurance to the UK. The customs value is £4,260. Duty at 2% is £85.20. Import VAT at 20% is charged on the customs value plus duty, £4,345.20, so it is £869.04. Import taxes total £954.24; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £85.20 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Construction: measure each passage against the drawing, examine a cut sample for reinforcement and check the joining web for uneven bonding or tearing.

Identification: compare gas identification, pressure marking and batch references with the approved sample and the reports for the production lot.

Connections: check thread direction, sealing faces, crimp dimensions and fitting retention against the agreed drawings; obtain recorded leak and pressure checks for assemblies.

Condition and packing: examine covers for cracks, bubbles and exposed reinforcement; check for flattened bores, tight kinks, dirty open ends and damage where the joined hoses separate.

What goes wrong

A supplier can reproduce the appearance of a twin welding hose while offering evidence for a different compound or reinforcement. Treat a report that does not identify the ordered hose as an unresolved specification issue. Colour and a pressure marking alone do not establish suitability for either gas.

Mismatched fittings, damaged sealing faces, loose crimps and a splitting joining web can make an assembly unusable. Separate suspect stock on arrival and compare it with the approved sample before releasing it for sale. Keep the hose batch and assembly test records together.
