Sourcing steel joist hangers from China

UK duty on steel joist hangers

Read from the UK Trade Tariff on 30 September 2026, heading 7308 covers iron or steel structures and their parts. Sheet-steel joist hangers may fit 7308 90 59 90; other fabricated structural supports may fit 7308 90 98 90. The table shows product variants sharing these candidate lines, rather than separate tariff classifications.

Both candidate lines carry 0% duty for goods from China. The supplied facts show no anti-dumping or countervailing duty, suspension, steel measure or attached import control on these lines. Import VAT is normally 20%. Confirm with HMRC or your customs broker whether and when the UK carbon border adjustment mechanism applies to goods under heading 7308; see the wider steel structures guide for background.

Send your customs broker the drawing, material, manufacturing method and intended structural use before declaring the goods. Confirm the classification through finding your commodity code; a supplier's description of the product as a bracket is insufficient.

Specify the hanger, support and fixing system

Specify whether the hanger fixes to timber, steel or masonry, and whether it is face-fixed, top-flange, concealed or skewed. Put the joist width, seat depth, steel thickness, hole layout, flange geometry and coating on the approved drawing. Agree the permitted dimensional tolerances and identify the exact nails, screws or bolts used with the hanger.

Ask for load evidence matching the hanger, supporting material, timber specification and fixing schedule. Have the project designer review its suitability. Do not accept a load table for a visually similar model or an installation using different fasteners.

For construction products, CE marking remains recognised in Great Britain. Products outside or not fully covered by a designated standard may use a technical assessment route. Ask the supplier to identify the route for the actual hanger and provide the corresponding performance declaration and assessment documents for review; do not assume a general structural-steel certificate covers it.

Worked duty example

Illustrative example, not a quote: Illustrative stock order of sheet-steel joist hangers for a building-products merchant under 7308 90 59 90, invoiced at £60,000 free on board, with £6,000 of freight and insurance to the UK. The customs value is £66,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £66,000, so it is £13,200. 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

Fit: measure the seat, side plates, flanges and fixing holes against the approved drawing; trial-fit the specified joist and fasteners.

Material: compare steel thickness and material certificates with the purchase specification; inspect bends and any welds for cracks or distortion.

Coating: check the agreed galvanising or coating thickness, coverage around holes and bends, bare patches and corrosion after unpacking.

Identity: match carton labels, hanger models, batch records and performance documents. Repeat the arrival checks before releasing stock. Use quality inspection to plan factory checks.

What goes wrong

A hanger can fit the timber yet differ from the tested design in steel thickness, hole positions or fasteners. Treat those differences as a reason to hold the batch for technical review. Agree that tooling, materials and fixing instructions cannot change without your approval.

Crushed cartons can bend flanges, while nested parts can rub through coatings. Separate damaged or unidentified stock on arrival. Do not supply construction products in Great Britain if you have reason to believe they fail the applicable requirements.
