Sourcing stainless steel MIG wire from China
Stainless steel MIG welding wire from China under heading 7223 pays 0% UK duty across all listed lines, with no listed trade remedy. Confirm the solid-wire code from its composition and check chemical safety obligations before importing or supplying it. Cambridge China Bridge sources stainless steel MIG welding wire.
Duty and classification for solid stainless MIG wire
Read from the UK Trade Tariff on 1 October 2026, heading 7223 covers wire of stainless steel. This guide concerns solid stainless MIG welding wire. Select the line using the actual alloy composition. The table includes the heading's broader composition categories, including chromium-aluminium resistance wire; inclusion does not establish suitability for MIG welding. Coated welding wire belongs under heading 8311, as explained in the site's published stainless wire guide.
All listed lines carry 0% duty for goods from China. No anti-dumping or countervailing duty, steel measure or suspension is listed. The tariff attaches import and export waste controls; confirm their applicability with your customs broker. For a shipment from China entering England as waste under notification controls, the exporter must apply to the competent authority in the country of dispatch for consent.
Give your broker the composition certificate, product description and details of any coating or core to confirm the commodity code. For the wider heading context, see stainless steel TIG welding wire. Confirm with HMRC or your customs broker whether and when these lines fall within the UK carbon border adjustment mechanism; review the UK carbon border adjustment guide when planning future imports.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Stainless wire with nickel 2.5% or more, other compositions | 7223 00 19 00 | 0% | None |
| Stainless wire with nickel below 2.5%, other compositions | 7223 00 99 00 | 0% | None |
| Stainless wire with nickel 28% to 31% and chromium 20% to 22% | 7223 00 11 00 | 0% | None |
| Wire with nickel below 2.5%, chromium 13% to 25%, aluminium 3.5% to 6% | 7223 00 91 00 | 0% | None |
Specify the filler alloy and spool feeding behaviour
State the parent metal, intended joint and service conditions, then agree the filler designation with your welding specialist. Specify solid wire, chemistry, diameter and tolerance, surface cleanliness, spool dimensions, hub fit, net weight and winding pattern. Agree a feed-and-weld trial using your torch, liner, contact tip and shielding gas before accepting the production batch.
Ask for a heat-linked composition certificate and spool labels that identify the filler designation and batch. Include limits for wire cast and helix in the purchase specification, with an agreed checking method. Approve packing that keeps the wire dry and protects spool flanges during transport.
Confirm the product's chemical status before import. Where supplied as a substance or mixture, chemical hazard classification is the responsibility of suppliers, including importers. UK REACH registration applies to substances, including substances in mixtures and, in limited cases, articles. Ask a specialist to assess applicability. A safety data sheet is required where a chemical is hazardous and supplied for workplace use.
Worked duty example
Illustrative example, not a quote: Illustrative: 1 tonne of stainless steel MIG welding wire on spools under 7223 00 19 00, invoiced at £4,000 free on board, with £1,100 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
Chemistry and traceability: match spool labels to the heat certificate and independently check sampled wire against the agreed filler composition.
Diameter and shape: measure diameter and ovality; check cast and helix against the agreed specification.
Winding and feeding: inspect for crossed turns, trapped ends and damaged flanges; run a sample through the intended feeder and torch.
Surface and packing: check for rust spots, drawing residue, moisture and damaged wrapping; compare a sample weld with the approved trial.

What goes wrong
A spool can carry the requested designation while its chemistry or certificate belongs to another batch. Crossed winding and distorted spools interrupt feeding; diameter variation and contaminated surfaces can undermine the agreed weld result. A smooth-looking sample is insufficient evidence of batch consistency.
Keep the approved trial spool and acceptance criteria, inspect production samples and hold mismatched batches for investigation. Use the quality inspection guide to arrange checks that connect certificates, spool identity and practical welding performance.

Frequently asked questions
What is the UK import duty on stainless steel MIG welding wire from China?
Solid stainless steel wire under heading 7223 carries 0% duty on every listed line in the supplied tariff facts. No trade remedy or steel measure is listed.
Which commodity code should I use for stainless MIG wire?
Choose by actual nickel, chromium and aluminium content, rather than the MIG description alone. Give your broker the composition certificate and confirm whether the wire is solid, coated or cored.
What should I test before accepting Chinese MIG wire?
Check filler chemistry, diameter, cast, helix and winding. Run a feed-and-weld trial with your intended equipment and shielding gas, then compare production samples with the approved spool.
Do I need a safety data sheet for stainless welding wire?
A safety data sheet is required if the product is a hazardous chemical supplied for workplace use. Confirm its chemical classification and request product-specific safety information before supply.
