Sourcing gear grinding machines from China

Zero duty and the correct gear-machine code

Read from the UK Trade Tariff on 1 October 2026, heading 8461 covers gear cutting, grinding and finishing alongside other metalworking machine tools. All supplied lines carry 0% duty for goods from China. The supplied data lists no anti-dumping or countervailing duty, suspensions or attached import controls. Import VAT is normally 20%.

For a grinding machine, check the gear-finishing descriptions against its function and adjustment system. The micrometric branches specify positioning in any axis to an accuracy of at least 0,01 mm, then distinguish numerically controlled machines from others. The abrasive gear-cutting row is a comparison for machines that cut gears, rather than an automatic classification for every grinder.

Send the process description, control specification and adjustment accuracy to your customs broker to confirm the commodity code. For related gear-cutting equipment within the heading, see gear hobbing machines.

Specify the grinding process and test gear

State whether you need generating or profile grinding, external or internal gears, and the gear materials and heat-treatment condition. Specify module, gear diameter, face width, helix range, bore or shaft mounting, wheel dressing, coolant filtration and the control system. Agree the electrical supply, installation needs, tooling and software included.

Attach a production gear drawing and agree acceptance criteria for tooth profile, lead, pitch, runout and surface finish. Request measured results from gears ground on the machine being supplied. For new machines supplied to Great Britain, confirm the applicable machinery safety, conformity marking, declaration of conformity and English-instruction requirements with HSE. The responsible person must compile the technical file and make it available on request.

Worked duty example

Illustrative example, not a quote: A gear grinding machine with tooling for a small gear shop (illustrative) under 8461 40 71 00, invoiced at £42,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £46,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £46,000, so it is £9,200. 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

Grinding trial: grind the agreed heat-treated blank with the supplied tooling and wheel, then compare the measured gear with the drawing and agreed acceptance criteria.

Wheel and coolant: check dressing operation, wheel mounting, coolant delivery, filtration and leaks; inspect the trial gear for burn, chatter and uneven finish.

Safety and documents: check guards, interlocks, emergency stops, conformity marking, declaration of conformity, English instructions and wiring diagrams.

Arrival and installation: inspect corrosion protection, transit restraints, spindle and fixture damage, and the tooling inventory; repeat the agreed grinding trial after installation. Use the inspection guide to plan the checks.

What goes wrong

A demonstration gear can hide problems if its material, heat treatment or geometry differs from your production parts. Poor dressing, unstable workholding or inadequate coolant can produce profile errors, chatter or grinding burn. Require a trial using your agreed blank and retain its measurement report.

Missing fixtures, unavailable control software or an incomplete English manual can delay commissioning even when the machine runs. Put the tooling, software access, documentation and repeat acceptance trial into the purchase specification.
