Sourcing oxyhydrogen micro-welders from China

2% duty on heading 8468

Read from the UK Trade Tariff on 1 October 2026, heading 8468 covers soldering, brazing and welding apparatus other than equipment of heading 8515, together with gas-operated surface tempering equipment. For an oxyhydrogen micro-welding purchase, distinguish the complete gas-operated apparatus from separately imported hand-held blowpipes and parts.

All listed lines carry 2% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, tariff suspension or attached import control. Other machinery under 8468 80 00 00 is a residual category, rather than a default code for every electrically powered gas generator.

Ask your broker to confirm the commodity code using the gas-generation method, welding function, technical drawings and shipment contents. Identify separately supplied generators, torches and accessories rather than assuming that everything shares the machine’s code. For the wider heading, see automated gas brazing machines.

Specify the generator, gas path and micro-flame

Specify whether hydrogen and oxygen leave the generator separately or as a mixture, the gas output at the stated operating pressure, compatible torch tips and the intended joint materials. For electrolytic models, record water quality, electrolyte composition, refill method, cooling, cleaning and replacement seals. Agree a demonstration using your actual workpieces and filler material.

Ask for a gas-path drawing identifying flashback protection, non-return devices, pressure relief and any liquid traps. Require evidence that the protection suits the actual gas mixture and flow. Have the factory document low-liquid, overpressure and overheating shutdown behaviour. Arrange these demonstrations under the manufacturer’s safe test procedure.

For models within the machinery rules, require the technical file arrangements and relevant conformity marking, and confirm declaration requirements and whether UKCA or CE marking is appropriate with the relevant product safety authority. For electrical equipment within the electrical safety rules, confirm the applicable declaration and conformity marking requirements with that authority; importers must ensure understandable English instructions accompany it. Check electromagnetic compatibility evidence for the complete powered configuration. Use testing and certification support to review the model’s applicable requirements.

Record maximum allowable pressure: pressure-equipment rules cover equipment and assemblies above 0.5 bar, so have the supplier assess applicability to the gas circuit. Check hazardous-substance compliance for the electrical assembly; products within those rules must show the importer’s name or trademark and contactable address on the product or packaging. If your business is an electrical-equipment producer under the waste-equipment rules, annual registration is required.

Worked duty example

Illustrative example, not a quote: 12 benchtop oxyhydrogen micro-welding machines, illustrative order under 8468 20 00 00, invoiced at £8,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £9,200. Duty at 2% is £184. Import VAT at 20% is charged on the customs value plus duty, £9,384, so it is £1,876.80. Import taxes total £2,060.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £184 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the delivered generator, torch, gas-path components and control board to the approved specification, nameplate, declaration and test reports.

Gas circuit: have a qualified tester check leak-tightness, hose condition, connections and the fitted protection against the manufacturer’s procedure. Review protection test records rather than deliberately causing a flashback during receiving inspection.

Performance: demonstrate the agreed joint on your workpieces, checking flame stability, tip adjustment, joint appearance and behaviour during sustained operation. Verify shutdown functions using the approved test method.

Arrival condition: inspect the tank, liquid traps, cooling vents, wiring and transit restraints; reconcile tips, seals, spares and English instructions with the packing list. Our quality inspection guide explains how to organise checks.

What goes wrong

A quoted gas-output figure can refer to conditions different from your torch setup. An unsuitable tip, restricted hose or liquid carry-over can undermine the demonstration result. Prevent disputes by recording the operating conditions, consumables and acceptance sample before production.

Watch for substituted seals or control boards, protection intended for a different gas system, leaking fittings and paperwork covering another model. Resolve discrepancies before shipment and check the delivered configuration again before commissioning.
