Sourcing automated gas brazing from China

UK duty on automated gas brazing machines

Read from the UK Trade Tariff on 1 October 2026, heading 8468 covers soldering, brazing and welding machinery other than equipment of heading 8515, and gas-operated surface tempering equipment. The gas-operated machinery line is the starting point for an automated flame-brazing machine. The table also identifies parts and accompanying manual equipment; these are separate goods descriptions.

All listed lines carry 2% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspension or attached import control. This tariff position does not replace machinery safety checks.

Confirm the commodity code using the heat source, operating sequence and supplied components. An electric controller does not describe how the joint is heated. For the wider heading, see gas welding torches and blowlamps.

Specify the joint, burners and automatic sequence

Send drawings and samples showing the parent metals, joint clearance, filler and flux, and the required finished joint. Specify fuel and oxygen arrangements, burner positions, gas connections, heating sequence, cooling, loading method and fixture adjustment. Agree acceptance checks for joint appearance, leakage and strength where relevant to the intended part.

Specify the electrical supply, controller language, recipe storage, guarding, emergency stops and gas shut-off behaviour. For supply in Great Britain, confirm with the relevant authority how the Supply of Machinery (Safety) Regulations 2008 apply to the machine and which declaration of conformity and CE or UKCA marking arrangements are appropriate. The technical file must be compiled and available on request. Ask for an English manual, gas schematic and electrical schematic matching the delivered configuration.

Worked duty example

Illustrative example, not a quote: An automated gas brazing machine with its workpiece fixtures, illustrative only under 8468 20 00 00, invoiced at £30,000 free on board, with £2,500 of freight and insurance to the UK. The customs value is £32,500. Duty at 2% is £650. Import VAT at 20% is charged on the customs value plus duty, £33,150, so it is £6,630. Import taxes total £7,280; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £650 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Joint quality: run your actual parts, filler and flux through repeated cycles; inspect alignment, filler flow, overheating and distortion against agreed acceptance samples.

Gas system: have a competent person check connections, leak-tightness, regulator compatibility, flashback protection and shut-off operation under the agreed test procedure.

Automatic sequence: check fixture location, burner movement, ignition, heating and cooling recipes, guard interlocks and emergency-stop response.

Arrival condition: compare the machine, burners, fixtures, spare parts, nameplate and conformity documents with the order; inspect transit damage before commissioning. Use the quality inspection guide to plan shipment checks.

What goes wrong

A demonstration using the supplier's parts can hide poor fit on your joints. Fixture movement, inconsistent joint clearance and uneven burner heating can produce incomplete filler flow or distortion. Agree trials using your own production materials and retain accepted samples and controller recipes.

Other failure points include incompatible gas connections, omitted flashback protection, undocumented component substitutions and paperwork describing a different configuration. Agree installation, commissioning, training and access to replacement burners and fixtures before ordering.
