Sourcing jewellery rolling mills from China

Zero duty on jewellery mills and relevant spares

Heading 8455 covers metal-rolling mills, their rolls and other parts. For jewellery workshops, the relevant complete-machine line is cold rolling mills. Replacement rolls need classification by material and manufacturing method; a grooved roll is not automatically an other-part item. See the wider rolling mills guide.

Read from the UK Trade Tariff on 3 October 2026, every selected line carries 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls. Import VAT is normally 20%. Zero customs duty does not establish that a powered mill meets machinery safety requirements.

Give your customs broker the mill specification, drive type and intended process. For spare rolls, include the material and manufacturing method; for other spares, provide drawings and their function. Confirm the commodity code before shipment.

Specify the sheet finish and wire grooves

State whether you need a hand-driven or powered mill, flat rolls, wire grooves or a combination. Specify usable flat width, roll diameter, opening range, groove profiles and the alloys and annealed condition you intend to process. Agree roll material, hardness, surface finish, parallelism and acceptable run-out against drawings.

Ask the factory to roll your intended sheet and wire samples. Agree the reduction sequence and check finished thickness across the sheet, surface marking, wire profile and adjustment repeatability. Specify bench fixings, handle clearance, lubrication instructions and replacement roll compatibility.

Powered mills supplied in Great Britain must meet the Supply of Machinery (Safety) Regulations 2008, including essential health and safety requirements, conformity assessment, UKCA or CE marking and a declaration of conformity. Check guarding, stops and the technical file arrangements. For hand-driven models, ask a compliance adviser to check the scope before specifying conformity paperwork. Our testing and certification service can help review the proposed evidence.

Worked duty example

Illustrative example, not a quote: Illustrative order: 12 replacement cold-rolling work rolls for jewellery mills under 8455 30 39 00, invoiced at £4,000 free on board, with £400 of freight and insurance to the UK. The customs value is £4,400. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £4,400, so it is £880. 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

Roll surfaces: inspect flat faces and grooves for rust, pitting, grinding marks and damaged edges; compare the material and hardness records with the agreed specification.

Alignment and adjustment: measure roll parallelism and run-out, operate the gap adjustment through its range and check bearings, gear engagement and handle movement for binding or excessive play.

Rolling trial: process the agreed sheet and wire samples safely, then measure thickness across the sheet and compare surface finish and groove output with approved samples.

Safety and packing: check mounting points, guards and powered controls against the approved design; match the model to its documents and inspect corrosion protection and crate restraint. Arrange quality inspection before dispatch.

What goes wrong

Use the trial to detect uneven sheet thickness from misaligned rolls, repeated marks from damaged roll faces and wire profiles that differ from the approved groove drawing. Loose adjustments and bearing play can make the result change between passes. Record the agreed acceptance checks before ordering.

A conformity mark alone does not guarantee safety. Check the actual machine before use, especially exposed gears, the roll entry and the stability of the bench mounting. Resolve missing guards or documents before accepting a powered mill; do not rely on paperwork for a different model.
