Sourcing machine-tool dividing heads from China

Duty on dividing heads and supplied accessories

Read from the UK Trade Tariff on 30 September 2026, dividing heads and other special machine attachments under 8466 30 00 00 carried 0% duty from China. The supplied facts list no anti-dumping or countervailing duty, suspension or attached import control for this line.

Heading 8466 covers machine-tool parts and accessories, including dividing heads. The table also includes separately supplied fixtures, work holders and collets that buyers may order alongside a head; these are not alternative codes for the complete dividing head. Each selected line carries 0% duty.

Confirm the commodity code using the head's function, drive arrangement and supplied components. See machine-tool rotary tables for related attachments and UK import duty and VAT for the tax calculation.

Specify the indexing mechanism and machine fit

State whether you need simple, universal or powered indexing. Agree the worm ratio, available index-plate hole circles, spindle taper and nose thread, centre height, mounting slots, tilt range and workpiece capacity. For universal heads, identify the host machine and agree the change gears and drive connection needed for the intended operation.

Put indexing accuracy, spindle runout, backlash and tailstock alignment into the purchase specification, with an agreed measurement method. List the chuck, plates, sector arms, centres, tailstock and mounting hardware individually. Ask for operating instructions covering indexing, locking, lubrication and adjustment.

Accessories that alter guarding or workholding can affect machine conformity, so ask the machine builder or safety adviser to confirm compatibility. For products within machinery supply rules, the responsible person must ensure safety before placing them on the Great Britain market or putting them into service. Work-equipment rules also place duties on businesses that own, operate or control the equipment.

Worked duty example

Illustrative example, not a quote: Illustrative order of 20 manual dividing heads under 8466 30 00 00, invoiced at £4,980 free on board, with £900 of freight and insurance to the UK. The customs value is £5,880. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £5,880, so it is £1,176. 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

Indexing: test the agreed divisions around a complete rotation, check the plate hole circles and pin engagement, and record angular error against the purchase specification.

Spindle and alignment: measure runout with a test bar and dial indicator, check the spindle interface, and compare head and tailstock alignment on the intended mounting surface.

Backlash and locking: reverse the handle to measure lost motion, check worm engagement, and confirm that the spindle lock holds without shifting the indexed position.

Completeness and condition: check plates, gears and mounting hardware against the packing list; inspect machined faces for burrs, rust and transit damage. Arrange quality inspection around these checks.

What goes wrong

A head can fit the table yet leave insufficient clearance for the cutter or tailstock. A matching centre height does not establish spindle alignment. Missing plate circles or change gears can prevent the planned divisions, while excessive backlash makes results depend on the direction of approach.

A stiff handle can conceal poor worm adjustment, and tightening the lock can move the spindle off its indexed position. Inspect the complete supplied assembly and repeat the agreed accuracy checks after mounting, before accepting it for production.
