Sourcing CNC tube bending machines from China

Duty and the tube-working commodity line

Read from the UK Trade Tariff on 30 September 2026, heading 8462 covers metal-forming machine tools, including tube-working machines. Numerically controlled machines for working tube, pipe, hollow section and bar, excluding presses, appear under 8462 51 00 00. The table shows product variants sharing this commodity line.

The supplied data records 0% duty for goods from China, with no anti-dumping or countervailing duty, suspension or attached import control. Confirm the commodity code from the machine's operating principle and specification, particularly whether it is a press. For wider heading coverage, see hydraulic plate rolling machines.

Specify the tube, bend geometry and tooling

Give the factory your tube material, outside diameter, wall thickness, section shape and part drawings. Specify bend centreline radius, bend angle, straight lengths between bends and finished-part tolerances. State whether the job needs rotary-draw bending or roll bending, and whether a mandrel and wiper die are needed.

Confirm which movements are controlled automatically: bending, tube feeding and tube rotation. List the bend dies, clamp dies, pressure dies and mandrels included for your parts. Agree trials using your actual tube material, controller language, programme backup access, software licences, electrical supply and spare tooling.

For new machines placed on the Great Britain market, CE or UKCA marking, a declaration of conformity and English instructions are required. Ask for documents matching the supplied machine and configuration, supported by testing and certification checks.

Worked duty example

Illustrative example, not a quote: Two CNC tube bending machines, illustrative order only under 8462 51 00 00, invoiced at £56,000 free on board, with £4,500 of freight and insurance to the UK. The customs value is £60,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £60,500, so it is £12,100. 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

Bend quality: measure finished angles, centreline radii and end positions against the drawing; inspect flattening, wrinkles, cracks and surface marks.

Repeatability: run the same saved programme with your tube material and check feeding, rotation, clamp grip and springback compensation.

Safety and controls: have a competent person check guards, interlocks and emergency stops; confirm English instructions, marking and the matching declaration.

Arrival condition: check tooling inventory, rust protection, hydraulic leaks, cabinet damage and transit restraints before commissioning. Agree the records through a quality inspection brief.

What goes wrong

A capacity claim without the tube material, wall thickness and bend radius leaves the purchase specification incomplete. Thin-wall tube may wrinkle or flatten, clamps may slip, and unsuitable tooling may mark the surface. A successful demonstration on the factory's tube does not establish performance on yours.

A machine described as CNC may leave feeding or rotation manual. Missing dies, locked controller parameters and unavailable programme backups can prevent production. Agree a finished-part acceptance test, tooling inventory and controller access before shipment, then repeat the agreed checks after installation.
