Sourcing Cold Rolling Mills from China
Cold rolling mills and the selected replacement rolls and parts from China carry 0% UK duty, with no anti-dumping or countervailing duty recorded. A complete mill supplied in Great Britain must meet machinery safety requirements; confirm UKCA or CE marking and declaration of conformity requirements with HSE. Cambridge China Bridge sources cold rolling mills.

Zero duty on cold rolling mills
Heading 8455 covers metal-rolling mills and their rolls. Cold rolling mills fall under 8455 22 00 00; replacement rolls and other mill parts have separate lines. Roll-forming machines, wire-drawing machines and presses belong elsewhere. See the wider rolling mills and mill rolls guide.
Read from the UK Trade Tariff on 7 November 2026, cold rolling mills and the selected rolls and parts carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls for these lines. Import VAT is normally 20%. Machinery safety requirements still apply.
Confirm the commodity code against the machine's function, roll material and supplied components before shipment. Give your customs broker the layout and packing list, especially where motors, drives or other equipment are supplied separately.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Cold rolling mills | 8455 22 00 00 | 0% | None |
| Open-die forged steel back-up rolls for cold rolling | 8455 30 31 00 | 0% | None |
| Open-die forged steel cold-rolling work rolls | 8455 30 39 00 | 0% | None |
| Other parts of metal-rolling mills | 8455 90 00 00 | 0% | None |
Specify the strip, reduction and mill layout
State the metal grade, incoming strip thickness and width, target thickness, permitted thickness variation, flatness and surface finish. Define whether the mill reverses or runs continuously, the required rolling speed under load, coil handling and the scope of the uncoiler, recoiler, tension control and coolant system. Agree a factory trial using your material and record the measured output.
Specify work-roll and back-up-roll dimensions, material, hardness scale, hardened depth, surface finish and bearing seats. Name the drive, gearbox, bearing and control suppliers. Request roll chemistry, heat-treatment records, hardness maps and ultrasonic reports against agreed acceptance criteria.
A complete mill supplied in Great Britain must meet the Supply of Machinery (Safety) Regulations 2008. Confirm the applicable guarding, emergency stop, UKCA or CE marking and declaration of conformity requirements with HSE. The responsible person must compile the technical file and make it available on request. Agree who integrates the line and signs its declaration. Use factory verification to check the builder's capability.
Worked duty example
Illustrative example, not a quote: 12 replacement cold-rolling work rolls, illustrative order under 8455 30 39 00, invoiced at £180,000 free on board, with £9,000 of freight and insurance to the UK. The customs value is £189,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £189,000, so it is £37,800. 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
Rolling trial: check output thickness across the strip and along its length, flatness, surface marks, tension stability and repeatability using the agreed material.
Rolls: compare dimensions, run-out, hardness maps and ultrasonic results with the approved drawings and acceptance criteria.
Safety and documents: check access to roll nips, guarding, interlocks and emergency stops; match the machine identity to its marking and declaration, and review the English operating manual.
Arrival: check corrosion protection, damaged journals, loose components and missing guards; reconcile the packing list and record installation alignment before acceptance. Agree the inspection stages through quality inspection.

What goes wrong
A trial with a softer or narrower strip can hide insufficient rolling force, unstable tension or poor thickness control. Require the agreed grade and dimensions, and retain measured results rather than accepting a video of the mill running without load.
Roll defects and unsuitable heat treatment can cause cracking or spalling. Poor alignment, damaged bearing seats and uncontrolled coolant can leave strip marks or unstable operation. An unclear supply boundary can leave guards, controls or conformity documents unfinished; settle the integration responsibilities before ordering.

Frequently asked questions
What is the UK import duty on cold rolling mills from China?
Cold rolling mills under 8455 22 00 00 carry 0% duty. The selected replacement rolls and parts also carry 0%, with no anti-dumping or countervailing duty recorded in the supplied tariff snapshot.
Does a cold rolling mill need UKCA marking?
For a complete mill supplied in Great Britain, confirm UKCA or CE marking and declaration of conformity requirements with HSE under the machinery safety rules. Agree who takes responsibility for the assembled line.
How do I check a cold rolling mill before shipment?
Run your specified strip grade and dimensions. Measure thickness variation, flatness and surface finish, and check tension control, guarding and emergency stops against the agreed acceptance plan.
What documents should replacement cold-rolling rolls have?
Request material chemistry, heat-treatment records, a hardness map and an ultrasonic test report. Match each roll to its drawing and agreed dimensional, hardness and internal-defect acceptance criteria.
