Sourcing aluminium argon cylinders from China

Duty on aluminium argon cylinders

Read from the UK Trade Tariff on 1 October 2026, heading 7613 covers aluminium containers for compressed or liquefied gas. Aluminium argon cylinders fall within the supplied line 7613 00 00 90, carrying 6% duty for goods from China. No anti-dumping or countervailing duty is listed. The table shows product variants sharing that commodity line.

The listed 0.00 % suspensions concern specified carbon-fibre-overwrapped natural gas or hydrogen containers and empty portable medical oxygen cylinders fitted with a valve and pressure and flow regulator. They do not cover argon cylinders. The UK Trade Tariff also attaches an import control of fluorinated greenhouse gases. The importer should confirm the requirement for the actual shipment with their customs broker; an argon-cylinder-specific declaration requirement has not been established here.

Confirm the material, gas service and whether cylinders arrive empty or filled through finding your commodity code. Agree how separately supplied valves and regulators will be classified. For related products within the wider heading, see aluminium compressed-air cylinders.

Specify argon service and filling compatibility

Specify pure argon or the intended gas mixture, water capacity, working and test pressure, alloy, dimensions, weight and finish. State whether the order includes valves and whether cylinders will arrive empty. Agree neck threads, valve outlet connections and valve protection with the intended filler before approving the sample.

For cylinders used to transport gas, confirm the applicable conformity-assessment and in-use periodic inspection and testing requirements with the relevant authority. For direct supply of finished transportable cylinders from China into Great Britain, specify the required Rho marking and obtain approval evidence matching the design. Ask for design approval, batch test records and a serial-number list before production.

Worked duty example

Illustrative example, not a quote: 2,000 empty aluminium argon cylinders for distributor stock; illustrative only under 7613 00 00 90, invoiced at £48,000 free on board, with £2,400 of freight and insurance to the UK. The customs value is £50,400. Duty at 6% is £3,024. Import VAT at 20% is charged on the customs value plus duty, £53,424, so it is £10,684.80. Import taxes total £13,708.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £3,024 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Approval: match the design approval and batch certificates to the cylinder model, gas service and serial numbers.

Threads and valves: gauge neck threads, compare valve connections with the approved sample and arrange a fit check with the intended filling equipment.

Testing: match hydraulic test records and batch burst-test results to the shipment; check agreed valve leak-test records where valves are supplied.

Condition and packing: inspect for dents, corrosion, damaged threads and illegible markings on arrival; check caps and packing protect necks and valve outlets.

What goes wrong

A cylinder can match the drawing yet be refused by the filler because its approval evidence, neck thread or valve outlet is unsuitable. Certificates covering another design and incomplete stampings create problems that a painted finish cannot resolve. Confirm the filler will accept the approved design before placing the production order.

Dents, damaged neck threads and loose valve protection can turn usable stock into rejected deliveries. Compare the shipment with the approved sample and serial-number records at quality inspection, then repeat the condition check on arrival before arranging filling.
