Sourcing grinding chucks from China
Electromagnetic grinding chucks and their other parts carry 0% UK duty from China, with no listed trade remedies. Where electrical safety rules apply, the importer must ensure instructions are in understandable English. Confirm holding performance on your actual workpieces. Cambridge China Bridge sources electromagnetic grinding chucks.
Zero duty on grinding chucks
Heading 8505 includes electromagnetic chucks and similar holding devices. Electromagnetic grinding chucks fall within the holding-device description at 8505 90 29 99; other parts are listed at 8505 90 90 90. The table shows chuck formats sharing the same commodity line, alongside the other-parts line.
Read from the UK Trade Tariff on 16 October 2026, the supplied records show 0% duty for these lines on goods from China, with no anti-dumping or countervailing duty, suspensions or attached import controls. Import VAT is normally 20%; see import duty and VAT.
Confirm the commodity code against the chuck's function and the contents of the shipment, particularly when a controller is supplied separately. For the wider product family, see magnets and magnetic holding devices.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Rectangular electromagnetic grinding chucks | 8505 90 29 99 | 0% | None |
| Other parts for electromagnetic grinding chucks | 8505 90 90 90 | 0% | None |
Match the chuck to the grinder and workpiece
Specify the working face, mounting arrangement, pole pattern, usable holding area and agreed flatness. Give the factory representative workpiece drawings, material, thickness and contact surface condition. Agree a holding test using those workpieces rather than accepting a pull-force claim measured on an unspecified steel block.
Specify the chuck supply, compatible controller, cable connections, coolant exposure and demagnetisation function. Ask the machine integrator to assess power-loss behaviour and the interface with grinding controls. Where the Electrical Equipment (Safety) Regulations apply, the importer must ensure understandable English instructions accompany the equipment; arrange a scope review through testing and certification.
Worked duty example
Illustrative example, not a quote: Illustrative order of 2 electromagnetic grinding chucks under 8505 90 29 99, invoiced at £3,000 free on board, with £600 of freight and insurance to the UK. The customs value is £3,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £3,600, so it is £720. 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
Face and mounting: measure flatness against the agreed drawing, inspect pole joints and edges, and confirm mounting holes and cable exit positions.
Holding: test representative workpieces across the usable face with the agreed method. HSE guidance says holding depends on material, surface condition and contact area.
Controller and release: confirm the supplied controller matches the chuck, check connections and run magnetisation and demagnetisation trials under competent supervision.
Condition and records: inspect for corrosion, transit damage and cable defects; match identification and test records to the delivered equipment. Use an agreed inspection plan.

What goes wrong
A chuck can hold a thick, clean test block yet perform poorly on the buyer's thin or uneven components. Unsuitable pole spacing, limited contact and contamination can undermine the trial result. Compare production samples with the approved workpiece test and record the surface preparation used.
Face distortion can affect grinding accuracy, while ineffective demagnetisation can leave parts attracting swarf after release. A mismatched controller or unclear wiring can delay installation. Agree acceptance tests and request matching connection drawings before approving shipment.

Frequently asked questions
What is the UK import duty on electromagnetic grinding chucks from China?
The supplied tariff records show 0% duty for 8505 90 29 99 and other parts at 8505 90 90 90, with no listed anti-dumping or countervailing duty.
How do I check the chuck will hold my parts?
Agree a holding trial using your actual material, thickness and contact surface. Record the test method and compare delivered chucks with the approved sample.
Should I buy the controller with the chuck?
Specify whether it is included. Match the controller output, connections and demagnetisation function to the chuck and have the grinder integration assessed.
What documents should I request?
Request mounting and connection drawings, matched test records and operating instructions. Where electrical safety rules apply, the importer must ensure understandable English instructions accompany the equipment.
