Sourcing stone slab polishers from China

Duty on stone slab polishing machines

Read from the UK Trade Tariff on 30 September 2026, heading 8464 covers machine tools for working stone and other mineral materials, and for cold working glass. Stone slab grinding and polishing machines fall within the other grinding or polishing machines line, 8464 20 80 00. The table distinguishes machine types sharing that tariff line.

The supplied tariff record shows 2% duty for goods from China throughout this heading, with no listed anti-dumping or countervailing measures, suspensions or attached import controls. This tariff position does not replace machinery safety requirements.

Confirm the machine's function and commodity code, especially where polishing is combined with cutting or profiling. See the wider stone and tile cutting machines guide for other machines within the heading.

Specify the slab, finish and water system

State the stone materials, slab width and thickness range, required surface or edge finish, and acceptable variation against an approved sample. Specify polishing head arrangement, spindle speed adjustment, tool holders, conveyor or table support, feed adjustment and access for maintenance. Agree a trial using material representative of your production.

Confirm the workshop power supply, water demand, drainage, slurry collection, controller language and spare parts. HSE guidance recommends effective water suppression and controlling the mist it generates. Ask how the machine connects to your proposed dust and mist controls.

For Great Britain, confirm with the relevant authority which UKCA or CE marking, declaration of conformity and English-instruction requirements apply to these machines under the Supply of Machinery (Safety) Regulations 2008. The responsible person must ensure the technical file is compiled and available on request. Match the machine identity to its documents before shipment.

Worked duty example

Illustrative example, not a quote: Two stone slab polishing machines, illustrative order under 8464 20 80 00, invoiced at £58,000 free on board, with £4,200 of freight and insurance to the UK. The customs value is £62,200. Duty at 2% is £1,244. Import VAT at 20% is charged on the customs value plus duty, £63,444, so it is £12,688.80. Import taxes total £13,932.80; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,244 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Finish: polish representative slabs and inspect for dull bands, scratches, swirl marks, uneven edges and damage at entry or exit. Compare the result with the approved sample.

Mechanics: check head movement, spindle noise, tool retention, conveyor tracking, slab support and repeatability after changing the feed setting.

Safety and water: check guards, interlocks, emergency stops and earthing. Run the water system and inspect for blocked jets, leaks near electrics and escaping mist.

Arrival: inspect transit restraints, frame alignment, corrosion and missing tooling. Match the nameplate, declaration and English manual to the delivered machine. Use an agreed quality inspection brief.

What goes wrong

A demonstration on an easy slab can hide poor finish on your actual stone. Uneven head pressure or worn tooling can leave bands; poor slab support can damage edges. Water leaks, spindle bearing problems and a controller available only in Chinese can interrupt production.

Agree the trial material, finish acceptance, tooling list and spare parts before ordering. Check the maker's ability to assemble and test the complete machine through factory verification. Repeat the agreed checks after installation.
