Sourcing low-hydrogen electrodes from China

Duty on low-hydrogen welding electrodes

Read from the UK Trade Tariff on 1 October 2026, heading 8311 covers flux-coated or cored welding and related consumables. Low-hydrogen coated electrodes of base metal for electric arc-welding fall within 8311 10 00 00. The table shows variants sharing this code, rather than separate tariff lines.

The supplied record shows 0% duty for goods from China under this line, with no anti-dumping or countervailing duty, suspension, steel measure or attached import control recorded. Import VAT is normally 20%; see the UK import duty and VAT guide.

Send the product description, coating details and intended welding process to your customs broker to confirm the commodity code. For cored wire and other consumables within this heading, see the welding electrodes and cored wire guide.

Specify the low-hydrogen coating and batch evidence

State the steel to be welded, electrode classification and applicable standard, diameter, length, welding positions, current and polarity. Agree the required weld-metal properties and hydrogen classification. Ask for test evidence identifying the exact product and batch, rather than accepting a catalogue description of low-hydrogen performance.

Specify sealed moisture-barrier or vacuum packaging, pack identification and batch traceability. Obtain the manufacturer's written storage, handling and any re-drying instructions for the exact electrode. Agree how opened packs will be handled at your workshop before approving the packaging.

Ask for a safety data sheet for the consumable. Employers must protect workers by controlling the health risks from welding fume. For electrodes supplied as construction products, check the applicable assessment route with testing and certification support. Construction products legitimately bearing CE marking can continue to be supplied in Great Britain.

Worked duty example

Illustrative example, not a quote: 20 cartons of low-hydrogen welding electrodes for a distributor's trial order; quantity, FOB value and freight are illustrative under 8311 10 00 00, invoiced at £2,000 free on board, with £600 of freight and insurance to the UK. The customs value is £2,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £2,600, so it is £520. 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

Identity: match the classification, diameter, length and batch number on sampled packs to the purchase specification and manufacturer's batch certificate.

Coating: check for cracks, chipped ends, loose coating and uneven coverage; compare sampled electrodes with the approved sample.

Moisture protection: check seals, vacuum-pack condition and evidence of wet cartons; retain the manufacturer's storage and handling instructions with the batch.

Trial weld: check arc stability, slag removal and bead condition; agree weld-metal testing against the required properties. Include these checks in the shipment inspection.

What goes wrong

A low-hydrogen description on the carton does not establish the batch's properties. Certificates may describe a different classification or fail to identify the delivered batch. Moisture in basic coatings can cause porosity or cracking, while damaged coatings can make welding inconsistent.

Keep questionable packs separate pending assessment. Obtain handling or re-drying instructions from the manufacturer for that product rather than applying a generic oven setting. Compare production batches with the approved sample and repeat trial welds when changing supplier or classification.
