Sourcing magnetic welding holders from China

Zero duty on magnetic welding holders

Heading 8505 covers permanent magnets, electromagnets and magnetic holding devices, among other goods. For a complete magnetic welding holder, 8505 90 29 99 is the holding-device line to check. The table also includes loose magnets and parts bought for manufacture or repair; these are distinct from complete holders.

Read from the UK Trade Tariff on 30 September 2026, all selected lines carried 0% duty for goods from China. The supplied record lists no anti-dumping or countervailing duty, suspension or attached import control for these lines.

Confirm the commodity code using the assembly drawing, magnetic mechanism and intended function. For the wider magnetic workholding family, see permanent magnetic workholding chucks.

Specify angles, contact faces and holding force

Specify fixed or adjustable angles, angle tolerance, contact-face dimensions, magnet material, coating and maximum working temperature. State whether the holder is permanently active or has a mechanical magnetic switch. Agree a holding-force test that records steel grade, thickness, surface finish, contact area and pull direction. Ask for a separate sliding-resistance test on the material you actually weld.

For supply as workplace equipment, importers have duties to ensure safety so far as reasonably practicable, arrange necessary testing or examination and provide safe-use information. Request instructions covering release, cleaning, heat exposure and trapping fingers. Keep the test results tied to the supplied model.

If holders are intended or reasonably likely to be used by consumers in Great Britain, general product safety rules apply. Importers must ensure applicable products are safe before placing them on that market. Where reasonable, the product or packaging must identify the producer's name and address and the product reference or batch.

Worked duty example

Illustrative example, not a quote: Illustrative order: 125 switchable magnetic welding holders 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

Geometry: measure the working angles and contact-face flatness against the drawing; check adjustable joints for movement after locking.

Grip: test samples using the agreed steel and surface conditions; record pull-off force and resistance to sliding rather than accepting a catalogue rating.

Release and construction: operate the magnetic switch repeatedly; inspect fasteners, exposed magnet edges, burrs and loose covers.

Arrival and packing: check for corrosion, cracked magnets and damaged faces; compare model markings and instructions with the approved sample. Use the same checks during quality inspection.

What goes wrong

A pull rating measured on clean, thick steel can give a misleading expectation on thin sheet, painted surfaces or curved tube. A holder may resist direct pull yet slide during assembly. Burrs, distorted plates and loose adjustable joints can also leave the joint at the wrong angle.

Heat beyond the magnet's working-temperature rating can permanently reduce strength. Agree the intended welding sequence and heat exposure with the factory, then compare holding force before and after a representative trial. Specify welding positioning as the intended use; do not treat a pull-force claim as evidence of suitability for lifting.
