Sourcing cored aluminium wire from China
Cored aluminium soldering wire from China carries 0% UK duty under the soldering and brazing line, with no trade remedy recorded. Hazardous chemicals supplied for workplace use require a safety data sheet. Confirm the alloy, flux and intended joining process. Cambridge China Bridge sources cored aluminium soldering wire.
Duty on cored aluminium soldering wire
Read from the UK Trade Tariff on 1 October 2026, heading 8311 covers base-metal products coated or cored with flux for soldering, brazing, welding or metal deposition. The relevant line for cored aluminium soldering wire is 8311 30 00 00, covering coated rods and cored wire for soldering, brazing or welding by flame.
The supplied record shows 0% duty for goods from China, with no anti-dumping or countervailing duty, suspension or attached import control recorded for this line. The table shows packaging variants under the same code, rather than separate tariff lines. Import VAT is normally 20%; see UK import duty and VAT.
Send your broker the alloy composition, flux-core details, product photographs and intended joining process to confirm the commodity code. Solid wire without flux is classified by its metal rather than as a flux-cored consumable. For the wider heading, see welding electrodes and cored wire.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Flux-cored aluminium soldering wire on spools | 8311 30 00 00 | 0% | None |
Specify the aluminium alloy and flux core
Describe whether the wire itself is aluminium-based or is another filler alloy sold for joining aluminium. Specify the filler composition, workpiece alloy, wire diameter, flux chemistry and content, melting range, heating method and joint geometry. Agree spool dimensions, net wire weight, winding, batch identification and moisture-resistant packaging.
Approve a sample joint on the actual workpiece material, using your intended surface preparation and heating method. Agree checks for wetting, joint strength, flux residue and cleaning. Ask for batch composition results and a safety data sheet matching the supplied formulation.
For chemical substances or mixtures, classification is the supplier's responsibility, including importers. Classification and labelling must be carried out by someone with scientific competence. Hazardous chemicals supplied for workplace use require a safety data sheet. Have the alloy and flux formulation reviewed through testing and certification support.
Worked duty example
Illustrative example, not a quote: 20 spools of flux-cored aluminium soldering wire; illustrative quantity, FOB value and freight under 8311 30 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 alloy and flux formulation, batch identification and composition report to the approved specification.
Wire and winding: measure diameter and net wire weight; check for flattened sections, cracks, tangled turns and damaged spools.
Joint trial: use sampled wire on the specified aluminium workpiece; check wetting, joint strength and residue against the agreed acceptance criteria.
Packing and documents: check seals, moisture protection, batch labels and the matching safety data sheet. Arrange a quality inspection.

What goes wrong
The description 'aluminium soldering wire' can leave the filler composition unclear. A sample may work on the supplier's demonstration piece but fail on your workpiece alloy or joint. Wrong flux chemistry, inconsistent core content or moisture exposure can produce poor wetting and variable joints.
Record the approved alloy, flux formulation, preparation and heating procedure together. Compare production batches with that specification and repeat the joint trial when the formulation changes. Agree how flux residue will be removed rather than accepting a general claim that cleaning is unnecessary.

Frequently asked questions
What is the UK import duty on cored aluminium soldering wire from China?
The supplied tariff record shows 0% under 8311 30 00 00, with no anti-dumping or countervailing duty recorded. Confirm that the wire is flux-cored and intended for soldering, brazing or flame welding.
Is aluminium soldering wire always made from aluminium?
Do not rely on the product name. Ask whether it describes the filler alloy or the material being joined, and obtain the filler composition and flux formulation before approving a sample.
Do I need a safety data sheet?
Hazardous chemicals supplied for workplace use require a safety data sheet. Obtain a sheet matching the actual alloy and flux formulation and have the chemical classification reviewed.
How should I test a sample before ordering?
Make a joint on your actual workpiece alloy with the intended preparation and heating method. Check wetting, joint strength, residue and cleaning against criteria agreed with the factory.
