Sourcing centreless grinding machines from China

Zero duty on the relevant grinding machine lines

Read from the UK Trade Tariff on 1 October 2026, heading 8460 covers machine tools finishing metal or cermets using grinding stones, abrasives or polishing products. Numerically controlled centreless grinding machines have a dedicated line. Non-numerically controlled machines grinding cylindrical surfaces fall within the broader cylindrical-surface line.

Both relevant lines carry 0% duty for goods from China. The supplied tariff facts list no anti-dumping or countervailing duty, suspensions or attached import controls for either line. The table contains only these relevant lines because the heading does not provide further separate centreless commodity lines.

Confirm the commodity code using the grinding process and control specification. A powered feed alone should not be your basis for selecting the numerically controlled line. See the wider grinding machines guide for other machines within the heading.

Specify the workpiece and centreless grinding setup

State whether the job needs through-feed or plunge grinding. Supply drawings and representative workpieces, identifying material, incoming condition, diameter, length, shoulders and stock removal. Agree the finished diameter, roundness, taper and surface finish to demonstrate on your parts.

Specify grinding and regulating wheels, work-rest blade, dressing arrangements, feed guides, coolant filtration and loading method. Agree what the control actually adjusts and which settings are retained with each job. Include installation services, lifting arrangements and the spares list in the purchasing brief.

For machinery supplied in Great Britain, confirm with the relevant authority or your customs broker the applicable essential health and safety requirements under the Supply of Machinery (Safety) Regulations 2008, including conformity documentation, marking and English instructions. CE marking remains recognised indefinitely in Great Britain. Check the conformity route for the supplied machine before shipment.

Worked duty example

Illustrative example, not a quote: Illustrative order: 5 numerically controlled centreless grinding machines under 8460 22 00 00, invoiced at £110,000 free on board, with £7,000 of freight and insurance to the UK. The customs value is £117,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £117,000, so it is £23,400. 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

Workpiece trial: grind your agreed parts using the intended feed method; record diameter, roundness, taper and surface finish against the contract, including results after the machine has warmed up.

Grinding setup: check wheel specifications, regulating-wheel adjustment, work-rest blade condition, dressing operation and feed-guide alignment. Look for chatter, scoring and inconsistent part feeding.

Safety and documents: check wheel guards and speed limits against the supplied wheels, test emergency stops and guard interlocks, and match the declaration and English manual to the machine identification.

Arrival condition: inspect corrosion protection, transit restraints, loose fittings and coolant equipment. After installation, repeat the agreed grinding trial. Use the quality inspection guide to plan factory and arrival checks.

What goes wrong

An acceptable sample can hide an unstable process. Wheel dressing, work-rest setup, regulating-wheel settings and coolant condition can change the result. Agree a repeatable trial on your workpieces rather than accepting a demonstration on the factory's easiest material.

Transit movement or poor installation can change alignment and introduce vibration. Photograph restraints before packing, inspect them on arrival and repeat the trial after installation. Do not accept a supplier's general catalogue accuracy claim as evidence that your delivered machine meets the agreed workpiece specification.
