Sourcing medical oxygen cylinders from China

Duty and the medical oxygen cylinder suspension

Read from the UK Trade Tariff on 1 October 2026, heading 7613 covers aluminium containers for compressed or liquefied gas. The supplied tariff file contains only commodity code 7613 00 00 90. The table shows medical oxygen cylinder configurations within that same line, rather than separate tariff lines. See the wider aluminium gas cylinder guide.

The ordinary duty for goods from China is 6%, with no anti-dumping or countervailing measure listed. The 0.00 % suspension covers empty portable aluminium medical oxygen cylinders fitted with a valve and a pressure and flow regulator. Do not assume a bare cylinder or a valve-only configuration qualifies. The other suspension concerns specified natural gas or hydrogen containers, outside this guide.

The tariff attaches an import control of fluorinated greenhouse gases. Official guidance reviewed does not establish the customs declaration requirement for these empty oxygen cylinders, so confirm it with your customs broker. Confirm the complete assembly and suspension eligibility through finding your commodity code.

Specify the cylinder, valve and filling connection

This guide concerns empty aluminium cylinders, rather than supplies of medical oxygen. Specify water capacity, working and test pressure, alloy, dimensions, weight, neck thread and oxygen service. State whether the order includes a valve and pressure and flow regulator, and agree the filling connection with the intended UK filler before approving the sample.

Ask for design approval, batch test records and the proposed permanent markings. Confirm with the relevant authority the conformity assessment and marking requirements for transportable pressure equipment before it is placed on the Great Britain market, and any periodic inspection and testing requirements in use. Rho marking is required for equipment following this route. Agree the applicable route with the assessment body, including whether the intended use is breathing apparatus.

Specify the regulator outlet, flow settings, gauge layout, valve protection and packing. Ask for oxygen-service cleaning records and an agreed cleanliness inspection method. Have a specialist assess the supplied valve and regulator assembly before approving production; use testing and certification support to organise the evidence review.

Worked duty example

Illustrative example, not a quote: Illustrative batch of empty aluminium medical oxygen cylinders without valves, using the ordinary duty rate 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: check that design approval and batch certificates identify the ordered cylinder, fitted accessories and shipment serial numbers.

Threads and function: gauge neck threads against the agreed drawing, confirm the filling connection and have a competent specialist check valve operation, leakage and regulator delivery.

Cleanliness and condition: review oxygen-service cleaning records and inspect for residue, moisture, dents, corrosion and damaged valve outlets.

Marking and packing: match permanent markings to certificates, check gauge and control labels, and confirm that protective packing prevents damage to necks and fittings. Plan these checks through the quality inspection guide.

What goes wrong

A certificate for a different cylinder design, an incompatible filling thread or incomplete marking can leave a shipment that the filler refuses. Dented cylinders, damaged valve outlets and inconsistent regulator operation also need resolving before acceptance.

A commercial description such as medical oxygen cylinder does not establish suspension eligibility. Record whether each cylinder is empty and portable and which fittings are supplied. Check that the purchase order, packing list and inspection report describe the same assembly.
