Sourcing hook spanners from China

Zero duty on hook spanners

Heading 8204 covers hand-operated spanners and wrenches and interchangeable spanner sockets. For hook spanners, the relevant distinction is between a fixed working profile and an adjustable design. The table repeats the applicable tariff lines for individual tools and spanner-only sets.

Read from the UK Trade Tariff on 30 September 2026, the non-adjustable and adjustable lines both carried 0% duty for goods from China. The supplied tariff data lists no anti-dumping or countervailing duty, suspensions or attached import controls for these lines.

Give your customs broker the drawing, adjustment mechanism and contents of any set to confirm the commodity code. See the adjustable spanners guide for the wider heading.

Specify the hook and locknut together

Send a drawing or sample of the mating locknut. Specify its outside diameter, slot width and depth, hook tip width, engagement depth, head thickness and handle clearance. For adjustable designs, agree the usable diameter range and check engagement at its extremes. A catalogue diameter alone does not establish fit.

Agree the steel grade, heat treatment, hardness acceptance criteria, finish and a proof-load test using a representative locknut. Record the permitted deformation and inspection method before production. Product safety compliance must be demonstrated before sale; keep the agreed drawing, test results and safe-use information with your purchasing records.

Worked duty example

Illustrative example, not a quote: 1,000 fixed hook spanners, illustrative order under 8204 11 00 00, invoiced at £4,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £6,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £6,000, so it is £1,200. 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 hook profile against the drawing and seat it in the actual locknut slot. Check that the tip engages fully without bottoming out and that the handle clears adjacent parts.

Strength: check material and hardness reports against the order specification. Apply the agreed proof load and inspect the hook root, head and handle for cracks or permanent bending.

Adjustment: operate the pivot or adjustment mechanism throughout the agreed range. Check play, retention and whether the hook stays engaged under the agreed test load.

Finish and packing: check burrs, sharp edges, flaking plating and rust. Confirm size markings match the tools, sets are complete and protective packing prevents metal surfaces rubbing.

What goes wrong

A shallow or poorly matched hook can ride out of the slot and damage the locknut. An oversized head may fit the nut on a bench but foul the surrounding assembly. Test samples on the intended assembly before accepting the drawing.

Soft hooks bend, brittle hook roots crack and loose pivots let adjustable tools twist away from the nut. Separate fit defects from material defects in the inspection report, and repeat the agreed checks on replacement samples. Use an agreed inspection brief for production and arrival checks.
