Sourcing rolling mill guide assemblies from China
Rolling mill guide assemblies from China provisionally fall under other mill parts, with 0% UK duty and no listed trade remedies. Check whether the supply is a replacement component or partly completed machinery; the latter needs assembly instructions and a declaration of incorporation. Cambridge China Bridge sources rolling mill guide assemblies.

Duty on rolling mill guide assemblies
Heading 8455 covers metal-rolling mills, their rolls and other parts. For guide assemblies identifiable as mill parts, 8455 90 00 00 is the starting point for classification. The table shows guide types against that same tariff line, rather than separate commodity lines.
Read from the UK Trade Tariff on 3 October 2026, the other-parts line carried 0% duty for goods from China. The supplied tariff facts list no anti-dumping or countervailing duty, suspensions or attached import controls. Import VAT is normally 20%.
Give your customs broker the assembly drawing, function and intended mill application to confirm the commodity code. For complete equipment and rolling rolls, see rolling mills and mill rolls.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Entry guide assemblies for metal-rolling mills | 8455 90 00 00 | 0% | None |
Specify the pass, mounting and guide rollers
Identify the mill stand, entry or exit position, rolled section and pass drawing. Specify mounting centres, locating faces, centre height, adjustment travel and clearances to neighbouring equipment. Include the drawing revision and whether rollers, inserts, bearings, fasteners and mounting brackets are included.
Specify body and wear-part materials, heat treatment, hardness with its measurement scale, roller profile, bearing designation, seals and lubrication connections. State the operating temperature, cooling arrangement and agreed wear criteria. Ask for material records and an inspection report tied to the assembly identification.
Confirm the supply category before ordering. Components outside specific product legislation can be supplied without conformity marking; do not assume every guide needs its own CE or UKCA mark. If the assembly is partly completed machinery, it needs assembly instructions and a declaration of incorporation. Agree who integrates it into the mill and checks the completed installation.
Worked duty example
Illustrative example, not a quote: Illustrative order of 12 replacement entry guide assemblies under 8455 90 00 00, invoiced at £28,000 free on board, with £4,000 of freight and insurance to the UK. The customs value is £32,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £32,000, so it is £6,400. 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
Fit: measure mounting holes, locating faces, centre height and guide opening against the approved drawing. Trial-fit the assembly to a mounting fixture where practical.
Rollers and bearings: check roller profile, alignment, free rotation and play. Confirm the bearing and seal designations and that lubrication reaches the intended points.
Materials and finish: match material and heat-treatment records to the parts. Check agreed hardness, contact surfaces, burrs, cracks and corrosion protection.
Arrival and records: check transport damage, missing inserts, fasteners and blocked lubrication ports. Match assembly identification to the packing list and inspection report. Use quality inspection to plan checks before dispatch.

What goes wrong
A guide can bolt into place yet sit off the pass centreline. Wrong roller profiles, unequal adjustment or loose bearing fits can mark the product and disrupt guidance. Copying a worn sample without the original drawing can reproduce wear as a manufacturing dimension.
Premature wear or seized rollers can follow unsuitable wear materials, inconsistent heat treatment, poor sealing or blocked lubrication. Keep an approved drawing and acceptance record, and agree which spare rollers, inserts and bearings remain interchangeable before accepting substitutions.

Frequently asked questions
What is the UK import duty on rolling mill guide assemblies from China?
The supplied tariff facts show 0% for other mill parts under 8455 90 00 00, with no listed anti-dumping or countervailing duty. Confirm that the assembly belongs in that line.
Do rolling mill guide assemblies need CE or UKCA marking?
Check the supply category. Components outside specific product legislation can be unmarked. Partly completed machinery needs assembly instructions and a declaration of incorporation.
What drawings should I send a Chinese guide manufacturer?
Send the pass and assembly drawings, mounting interfaces, centre height, roller profile and adjustment requirements. Identify the mill stand, drawing revision and included wear parts.
How do I check replacement guides before installation?
Measure mounting and locating features, check guide alignment and roller rotation, verify bearings and lubrication ports, and compare material and hardness records with the agreed specification.
