Sourcing Swiss-type CNC lathes from China

UK duty and classification

Read from the UK Trade Tariff on 21 November 2026, heading 8458 covers lathes, including turning centres, for removing metal. The relevant horizontal numerically controlled lines all carry 2% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty and no suspensions.

The tariff attaches an import control of fluorinated greenhouse gases to these lines. Ask whether the machine or an included refrigeration unit contains refrigerant, and obtain its specification. Official guidance includes pre-charged equipment within other products. The importer should confirm the applicable requirement and declaration with their customs broker before shipping.

The table lists classification alternatives, not interchangeable codes. Give your broker the sliding-head arrangement, spindle configuration and machining functions, and confirm the commodity code. Use the lathes and CNC turning centres guide for the wider heading.

Specify the sliding head, guide bush and bar feeder

Specify bar diameter and material, guide-bush or guide-bushless operation, headstock travel, usable turning length and the guide bush supplied for your stock. Agree bar straightness and diameter tolerances with the builder. Identify driven tools, sub-spindle transfer, back-working operations and the parts catcher needed for your drawings.

Name the control and enabled options, feeder interface, collets, cutting tools, coolant filtration, chip removal and electrical supply. Agree an acceptance run using your bar stock and drawings, including dimensions, surface finish and performance after warming up. Confirm the applicable UK machinery supply rules, declaration of conformity, accepted marking and English instructions with the relevant authority.

Worked duty example

Illustrative example, not a quote: Illustrative order: 6 Swiss-type sliding-head CNC turning centres for a machining business under 8458 11 20 00, invoiced at £150,000 free on board, with £9,000 of freight and insurance to the UK. The customs value is £159,000. Duty at 2% is £3,180. Import VAT at 20% is charged on the customs value plus duty, £162,180, so it is £32,436. Import taxes total £35,616; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £3,180 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Bar support: check the supplied guide bush and collets against the agreed stock, and run the feeder to check alignment, vibration and bar-end handling.

Cutting accuracy: measure agreed parts after warming up, including slender sections, concentric features and back-worked surfaces; repeat the test after installation and levelling.

Transfer and options: demonstrate sub-spindle pick-up, driven-tool operations, parts collection and the quoted control options using the agreed programme.

Safety and documents: test door interlocks and emergency stops, check feeder guarding, and match the declaration, English manual and machine identity. See quality inspection explained.

What goes wrong

A guide bush that does not suit the bar stock can cause scoring, unstable dimensions or feed problems. Feeder misalignment can produce vibration, while poor chip evacuation can interrupt unattended cutting. A machine demonstrated on short, easy parts may not prove its ability to cut your slender components.

Missing driven-tool options, incompatible feeder interfaces and unreliable sub-spindle transfer can leave quoted operations unfinished. Record the acceptance setup, tooling and measured parts before crating, then reproduce that setup on arrival. Check paperwork against the delivered machine rather than a similar model.
