Sourcing MIG contact tips from China

Contact-tip duty and the attached control

Read from the UK Trade Tariff on 17 October 2026, heading 8515 covers electric welding and soldering apparatus and parts. For separately supplied MIG contact tips, the relevant candidate in the supplied data is 8515 90 80 90, other parts. The table shows contact-tip variants sharing that candidate code, rather than separate tariff classifications.

The supplied tariff data lists 0% duty for goods from China, with no additional anti-dumping or countervailing duty rate and no suspension recorded. However, the UK Trade Tariff attaches an anti-dumping or countervailing registration control to this line. The importer should confirm its applicability and requirements with their customs broker before shipment.

Give your broker the material specification, drawing and intended torch application to confirm the commodity code. For complete equipment, see welding and soldering machines.

Specify the bore, thread and copper grade

Specify the torch make and model, mating tip holder, thread diameter and pitch, overall length, shoulder position and wire diameter. Agree the bore dimensions and tolerances on a drawing. A catalogue description saying compatible is insufficient without a sample fitted to your actual holder.

State the copper or copper-alloy grade, hardness, surface finish and any coating. Ask for material evidence tied to the production batch. Agree a sample welding trial using your wire, torch and operating conditions, with acceptance criteria for feeding, heating and wear.

HSE guidance says workplace-product supply obligations include safe-use information and the testing or examination necessary for compliance. Request fitting and replacement instructions identifying the intended torch applications and operating restrictions.

Worked duty example

Illustrative example, not a quote: 5,000 MIG welding contact tips, illustrative order only under 8515 90 80 90, invoiced at £4,500 free on board, with £600 of freight and insurance to the UK. The customs value is £5,100. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,100, so it is £1,020. 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

Dimensions: check bore size and concentricity, thread fit, length and shoulder seating against the approved drawing and sample.

Material: match the declared copper grade and hardness to batch evidence; investigate unexplained changes in appearance, weight or finish.

Function: check smooth wire passage and secure seating, then run a sample welding trial and inspect for sticking, excessive heating and bore wear.

Packing: check size labels, batch identification and quantities; inspect for damaged threads and mixed variants using an agreed inspection plan.

What goes wrong

Tips can screw into a holder yet seat incorrectly, leaving the working end in the wrong position. Burrs or an uneven bore can drag on the wire, while an oversized bore or inconsistent material can undermine the agreed welding performance. Check the complete fit and trial performance rather than appearance alone.

Mixed wire sizes and unapproved material substitutions make repeat orders difficult to control. Keep an approved drawing and sample for each variant, require approval before changes, and compare incoming batches with the same inspection criteria.
