Sourcing tungsten TIG blanks from China

Zero duty, with classification by supplied form

Read from the UK Trade Tariff on 1 October 2026, heading 8101 covers tungsten and its articles. Relevant forms include simply sintered rods, worked rod blanks and wire stock. The table gives candidate material forms, not interchangeable codes. HMRC's tungsten-alloy rod notice excludes the described blunt rods from classification as welding-machine parts. Match the actual manufacturing process and supplied condition before choosing a code.

The listed lines carry 0% duty for goods from China, with no anti-dumping or countervailing duty rate or suspension listed in the supplied snapshot. It attaches anti-dumping or countervailing registration to 8101 99 10 00. The published background guide identifies this registration with consignments from Laos and Thailand, rather than direct consignments from China; registered imports can face retrospective duty. Confirm the consignment route with your broker.

The snapshot attaches import and export waste controls to the wire and other-article lines. Environment Agency guidance for England says waste shipment controls apply only to waste. For material from China, ask your customs broker to confirm whether the attached control requires documents for your shipment, particularly if it contains rejects or reclaimed material. Confirm the commodity code; see tungsten rods for the wider product family.

Chemistry, rod condition and grinding allowance

Specify non-thoriated blanks, tungsten content, the identity and content of any oxide additions, diameter, length, straightness and dimensional tolerances. State whether the rods are simply sintered, drawn, ground or cut, and whether their ends remain blunt. Agree the stock allowance for final tip grinding, surface cleanliness, batch identification and protective packing. Approve a sample in the intended torch and welding process before releasing the production order.

Check the UK REACH position for the supplied material form. Registration applies to substances, substances in mixtures and, in limited cases, substances in articles. Ask for composition and intended-use information before deciding how the blanks should be treated.

Worked duty example

Illustrative example, not a quote: Illustrative distributor order: 500 kg of worked tungsten electrode rod blanks under 8101 99 10 00, invoiced at £30,000 free on board, with £800 of freight and insurance to the UK. The customs value is £30,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £30,800, so it is £6,160. 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

Composition: match the batch analysis to the ordered tungsten grade and oxide additions; arrange independent analysis where grade substitution would affect use.

Geometry: measure diameter, length and straightness against the drawing; check fit in the intended collet and the allowance left for tip grinding.

Surface and ends: inspect for cracks, chipped ends, grinding damage and contamination; compare the supplied finish with the approved sample.

Traceability and trial: match rod bundles and labels to batch certificates; prepare sample tips and compare arc starting and stability under the agreed welding conditions.

What goes wrong

Mixed grades can look alike, while incorrect diameter or bowed rods cause poor collet fit. Brittle blanks can arrive chipped or crack during tip preparation. Keep grades and batches separate, specify protective packing and record whether a defect was visible before grinding.

A description such as electrode blank does not explain the manufacturing stage. Record the process and end condition on the purchase specification and shipping paperwork. Investigate chemistry, tip preparation and welding conditions together when the trial gives unstable results, rather than accepting colour marks as proof of composition.
