Sourcing welded oval steel tubes from China

Duty and commodity codes for oval tubes

Read from the UK Trade Tariff on 1 October 2026, heading 7306 covers other iron or steel tubes, pipes and hollow profiles, including welded products. Welded oval tubes fit the other non-circular cross-section descriptions: 7306 69 10 00 for stainless steel and 7306 69 90 00 for other steel. The table repeats these codes for different finishes.

Both relevant lines record 50% third-country duty for goods from China, with no anti-dumping or countervailing duty, suspension or import control recorded. The related published guide discusses steel quota relief; ask your customs broker whether relief is available for the exact entry rather than assuming it applies.

Send your broker the cross-section drawing, steel specification and description of the goods as shipped. Confirm the code using finding your commodity code. For the wider heading, see welded precision steel tubes. For imports from 1 January 2027, review the UK carbon border adjustment guide and ask the mill for emissions information.

Specify the oval profile and downstream use

Define whether the profile is elliptical or has straight sides with rounded ends. Put the major and minor outside dimensions, wall thickness, length, straightness, twist and permitted variation on the drawing. State the steel grade, weld position, internal weld bead condition, end preparation and finish. Use an approved sample to settle appearance and fit.

Tell the factory whether the tube will be bent, welded into a frame, used decoratively or supplied for construction. For construction use, check the applicable product standard and conformity documents before ordering. Government guidance confirms that construction products bearing legitimately affixed CE marking can continue to be supplied to the Great Britain market. Arrange testing and certification around the actual use.

Worked duty example

Illustrative example, not a quote: Illustrative order: 6 tonnes of uncoated welded non-alloy steel oval tubes under 7306 69 90 00, invoiced at £6,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £10,000. Duty at 50% is £5,000. Import VAT at 20% is charged on the customs value plus duty, £15,000, so it is £3,000. Import taxes total £8,000; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £5,000 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Profile: measure the major and minor dimensions and wall thickness at several positions; check straightness, twist and fit in the receiving component.

Weld: inspect the seam for cracks and inconsistent bead removal; trial-bend or flatten samples where relevant to your fabrication process.

Material: match bundle identification and heat numbers to mill certificates; confirm that the supplied grade matches the order.

Finish and packing: check polishing direction, coating coverage, cut-end burrs and dents; inspect separators and moisture protection. Use an agreed quality inspection plan.

What goes wrong

An oval tube can match its overall width and height yet have the wrong curvature, so it will not fit a bracket or connector. Forming can leave uneven wall thickness, twist or a weld seam that opens during bending. A polished sample can also hide a seam that remains visible across the production batch.

Keep the drawing, approved sample and material records together. Repeat the fit and fabrication checks on arrival before releasing stock to production. Do not accept a circular-tube description for an oval shipment without reviewing the classification, or a generic certificate that cannot be matched to the supplied tube.
