Sourcing cylindrical grinders from China

Duty on cylindrical grinding machines

Read from the UK Trade Tariff on 21 November 2026, heading 8460 covers abrasive finishing machine tools for metal or cermets. Cylindrical grinding machines include machines grinding external or internal cylindrical surfaces and centreless machines. For context within the wider heading, see our surface grinding machines guide.

The relevant lines carry 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. The table separates external and internal numerically controlled configurations sharing the same commodity line; they are not separate tariff subdivisions.

Confirm the commodity code from the grinding process, whether the machine is centreless and whether it is numerically controlled. Gear grinding machines fall under heading 8461. Import VAT is separate from duty; see UK import duty and VAT.

Specify the workpiece and grinding process

State whether you need external, internal, plunge, traverse or centreless grinding. Specify workpiece material, grinding diameter and length, workholding, wheel dimensions, spindle speed, dressing, coolant filtration and measuring options. For centreless work, agree the regulating wheel, work-rest blade and feeding arrangement.

Agree a representative test part and acceptance criteria for diameter, roundness, taper and surface finish. Record the wheel, dressing settings and coolant used during acceptance so the arrival trial can reproduce the factory trial.

Confirm with the relevant authority which essential health and safety requirements, conformity documentation, marking and English instructions apply to the machine under the Supply of Machinery (Safety) Regulations 2008. Responsible persons must ensure the technical file is compiled and available on request. Request the exact machine's supporting documentation before shipment.

Worked duty example

Illustrative example, not a quote: 5 numerically controlled cylindrical grinding machines, illustrative order under 8460 23 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

Geometry and finish: grind the agreed workpiece and measure diameter along its length, roundness, taper and surface roughness. Record spindle run-out and look for chatter or grinding burn.

Workholding and feeds: check centres, chuck or collet alignment, tailstock movement and slide travel. On centreless machines, check blade condition, regulating wheel adjustment and stable feeding.

Guarding and documents: check wheel guards, spindle speed limits and the supplied wheel's speed marking. Test emergency stops and match the machine identity to its conformity declaration and English manual.

Arrival condition: inspect for corrosion, displaced slide locks, coolant leaks and damaged cables. Level and install the machine as instructed, then repeat the agreed grinding trial. Our quality inspection guide explains inspection stages.

What goes wrong

A short demonstration on an easy workpiece can conceal taper, chatter or unstable centreless feeding on your actual part. Agree the workpiece and measurement method before ordering, and retain the factory results for comparison after installation.

Poor transport restraint can disturb alignment, while inadequate coolant filtration can degrade the finish. Record slide locking, bracing and corrosion protection before crating. Confirm which centres, blades, dressers and measuring accessories are included rather than relying on catalogue photographs.
