Sourcing stainless I-beams from China

Duty depends on how the beam is made

Read from the UK Trade Tariff on 2 October 2026, heading 7222 covers other stainless steel bars and rods, and angles, shapes and sections. This guide concerns stainless steel I-beams supplied as sections. The table separates manufacturing and processing routes; it does not give interchangeable codes for the same beam.

The supplied tariff snapshot lists 0% for 7222 40 10 00, 7222 40 90 10 and 7222 40 90 90, and 50% for 7222 40 50 00. These lines show no anti-dumping or countervailing duty, suspension or attached import control. No separate steel measure is flagged in the supplied facts. Have your broker check the live tariff before shipment.

Send your broker the section drawing, material certificate and manufacturing description, including welding, cladding and further processing, to confirm the commodity code. For the wider heading, see our stainless channel sections guide.

Specify the flange, web and manufacturing route

Specify the stainless grade, overall depth, flange width, web and flange thickness, length, straightness, twist and dimensional tolerances on an approved drawing. State whether the beam is rolled or assembled by welding, and agree the surface treatment and weld inspection needed. Ask for heat-linked material certificates with chemistry and mechanical test results.

For building projects, ask your compliance adviser to confirm the applicable construction-product standard, performance documentation and marking before ordering. CE marking remains recognised for construction products in Great Britain. Obtain the declaration of performance and supporting assessment documents appropriate to the proposed supply, and have the project engineer review suitability for the intended load and environment.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of hot-rolled stainless steel I-beams under 7222 40 10 00, invoiced at £56,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £59,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £59,000, so it is £11,800. 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

Material: match beam and bundle heat markings to the mill records, and arrange sampled grade verification.

Geometry: measure depth, flange width and thickness, web thickness and length; check flange alignment, straightness and twist against the drawing.

Welds and finish: for welded beams, check the agreed weld profile and test reports; inspect for cracks, distortion, surface damage and treatment residue.

Packing and records: check bundle identification, separation from carbon steel and protection of flange edges. Plan arrival checks using our quality inspection guide.

What goes wrong

An order described only as a stainless I-beam leaves room for a different manufacturing route, thinner flanges or a substituted grade. Weld distortion can prevent fit-up, and material certificates may belong to another heat. Put the drawing, route, tolerances and document list into the purchase specification before approving production.

A quotation can assume the wrong tariff line, while a generic certificate may not support the proposed building use. Confirm classification with the broker and review construction documentation before dispatch. Compare the factory's equipment and records through factory verification.
