Sourcing carbide glass wheels from China

UK duty on unmounted carbide glass-cutting wheels

Heading 8209 covers unmounted plates, sticks, tips and similar tool parts of cermets. For the unmounted carbide wheels covered here, the relevant supplied line is 8209 00 80 00, “Other”. The table shows buying variants sharing that line, rather than separate tariff subdivisions. Keep complete glass cutters and wheels supplied in holders separate when checking classification.

Read from the UK Trade Tariff on 4 October 2026, the supplied heading lines carry 0% duty for goods from China. The record lists no anti-dumping or countervailing duties, suspensions or attached import controls. Import VAT is normally 20%; see UK import duty and VAT.

Confirm the commodity code using the wheel's material, function and supplied condition. Give your broker the drawing and photographs showing whether the wheel is unmounted. For the wider heading, see carbide inserts and tool tips.

Specify the scoring edge and axle fit

Specify outside diameter, thickness, axle bore, bore finish and dimensional tolerances against a drawing. Identify the cutter head and axle the wheel must fit. State the cutting-edge angle and whether the edge is smooth or serrated; agree the serration geometry where relevant. Describe wheels supplied loose separately from assembled cutter heads.

Agree the cemented-carbide grade, binder composition and any coating. State the glass type, thickness range, scoring direction, speed, pressure and lubrication for the intended application. Approve samples by scoring and breaking your own representative glass, recording score continuity, break accuracy, edge chipping and wear.

Tools supplied for use at work must be accompanied by adequate information for safe use. Confirm the applicable safety obligations with HSE. Request instructions covering intended glass, mounting, operating conditions and recognising damaged wheels. Keep the approved drawing, trial record and batch identification together.

Worked duty example

Illustrative example, not a quote: Illustrative order: 2,000 unmounted carbide glass-cutting wheels for a tooling distributor under 8209 00 80 00, invoiced at £2,000 free on board, with £800 of freight and insurance to the UK. The customs value is £2,800. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £2,800, so it is £560. 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

Dimensions: measure outside diameter, thickness and bore against the drawing; check sample wheels on the intended axle for free rotation and unwanted play.

Scoring edge: inspect under magnification for chips, burrs and uneven grinding; compare edge angle and any serrations with the approved sample.

Glass trial: score and break representative glass under the agreed conditions; compare score continuity, break line, edge chipping and wheel wear.

Arrival condition: check protective separation, damaged edges, variant labels, batch identification and instructions. Set out these checks in the inspection brief.

What goes wrong

A wheel can match the outside diameter but bind on its axle or wobble because the bore or thickness is wrong. An unsuitable edge angle or serration pattern can give interrupted scores and chipped breaks. Trial the wheel in the actual cutter head with the intended glass, rather than accepting appearance alone.

Changes in carbide grade or grinding can shorten working life between batches. Loose wheels can chip each other during transport, while mixed labels conceal different edge geometries. Retain an approved sample for each variant, compare shipment samples with it and require packing that separates the cutting edges.
