Sourcing tool and cutter grinders from China
Tool and cutter grinding machines from China carry 0% UK import duty, whether numerically controlled or otherwise. Confirm applicable machinery safety, conformity marking, declaration of conformity and English instruction requirements with the relevant authority. Cambridge China Bridge sources tool and cutter grinding machines.
Duty and classification for tool and cutter grinders
Read from the UK Trade Tariff on 25 October 2026, heading 8460 covers machine tools finishing metal or cermets using grinding stones, abrasives or polishing products. This guide covers its sharpening machines for tools and cutters. See the wider grinding machines guide for other machine types.
Chinese-origin tool and cutter grinding machines carry 0% duty under 8460 31 00 00 when numerically controlled and 8460 39 00 00 otherwise. The supplied tariff facts list no anti-dumping or countervailing duty, suspensions or attached import controls for these lines. The table separates tool and cutter descriptions within the same codes.
Confirm the commodity code using the machine's actual sharpening function and control system. A supplier's description of a machine as automatic does not establish that it is numerically controlled.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Numerically controlled tool grinding machines | 8460 31 00 00 | 0% | None |
| Tool grinding machines, other than numerically controlled | 8460 39 00 00 | 0% | None |
Specify the cutter geometry and grinding setup
Identify the tools to sharpen, their material, shank diameter, cutting length and required flute, relief and rake geometry. Agree the wheel type, diameter and bore, spindle speed range, indexing arrangement, collets, fixtures, dressing system and coolant filtration. Specify the electrical supply and extraction connections for your workshop.
For numerically controlled machines, agree which tool geometries the supplied software can produce, which functions need separate licences, and how programmes are backed up. Make acceptance depend on grinding your representative tools and measuring the agreed geometry, run-out and finish.
Confirm with the relevant authority the applicable essential health and safety requirements of the Supply of Machinery (Safety) Regulations 2008, conformity marking, declaration of conformity and English instruction requirements for machines placed on the market. CE marking remains recognised in Great Britain. Arrange a review of the exact machine's documentation through testing and certification.
Worked duty example
Illustrative example, not a quote: Illustrative order: 5 numerically controlled tool and cutter grinding machines under 8460 31 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
Tool geometry: grind the agreed sample tools and measure cutting diameter, relief angles, flute consistency and cutting-edge finish against the purchase specification.
Workholding and movement: check collet fit, spindle run-out, indexing repeatability and slide movement; repeat the sample grind after releasing and reclamping the tool.
Guarding and operation: check wheel guards and wheel speed compatibility, test emergency stops, and run the coolant and extraction arrangements during grinding.
Documents and shipment: match the declaration and English manual to the machine identity, verify supplied fixtures and software access, and check transport locks before crating. Repeat the agreed accuracy checks after installation using the quality inspection guide.

What goes wrong
A demonstration tool can hide unsuitable workholding or missing software functions. A machine may sharpen a simple cutter but struggle with your flute geometry or relief profile. Loose collets, indexing play and spindle vibration can produce unequal cutting edges or chatter. Use your own representative tools for acceptance rather than accepting a video of an unrelated grind.
Shipping movement can disturb alignment, while poor coolant filtration can spoil the cutting edge. Record the factory test setup, secure moving assemblies and repeat the same grind after installation. Confirm with the relevant authority how the Provision and Use of Work Equipment Regulations 1998 apply to workplace use and what responsibilities your business has for wheel mounting, guarding and operator training.

Frequently asked questions
What is the UK import duty on tool and cutter grinders from China?
The supplied tariff facts show 0% duty for both 8460 31 00 00 and 8460 39 00 00, with no anti-dumping or countervailing duty.
Which code covers a numerically controlled tool grinder?
8460 31 00 00 covers numerically controlled sharpening machines for tools or cutters. Other tool and cutter sharpening machines fall under 8460 39 00 00.
What paperwork should accompany a tool grinding machine?
Check the declaration of conformity, conformity marking and English instructions for the exact machine. Review the safety documentation alongside the physical guarding and controls.
How should I test a cutter grinder before shipment?
Have the factory grind your representative cutters using the supplied fixtures and software. Measure geometry, run-out and finish, then repeat after reclamping to check repeatability.
