Sourcing automatic screw feeders from China

UK duty and classification for screw feeders

Read from the UK Trade Tariff on 4 October 2026, the selected lines carry 0% ordinary duty for goods from China, with no anti-dumping or countervailing duty and no suspensions recorded. Heading 8479 covers machines with individual functions not specified elsewhere in the chapter. The table includes candidate lines for standalone feeders, machinery parts and robotic assemblies; these are not interchangeable classifications.

The residual machine line carries fluorinated greenhouse gas and waste import controls, plus a waste export control. The residual parts line also carries a fluorinated greenhouse gas import control. For waste imported into England under notification controls, the Chinese exporter must seek consent from the dispatch authority. Imported fluorinated-gas equipment must be correctly labelled. Have your customs broker confirm which attached controls and declaration requirements apply to the actual shipment.

Confirm the commodity code using the feeder's function, construction and supplied configuration. Identify whether it only presents screws, blows them through a tube, or forms part of a robotic fastening system. See industrial robot arms for the wider heading and import duty and VAT for the calculation method.

Specify the screw and the delivery interface

Send production screws and drawings showing thread diameter, overall length, head shape, head diameter, recess and coating. Specify whether screws are presented for manual pickup or delivered through a tube to a screwdriver. Agree the hopper, track, escapement, tube and nozzle configuration for each screw family, including the changeover parts.

Define accepted feed performance using your screws, the intended hopper fill range and the actual pickup or driver interface. Record jams, empty deliveries, doubled screws and damaged finishes. Specify power supply, compressed-air conditions where used, control signals and access for cleaning. Agree replaceable wear parts and obtain a parts drawing.

For complete machines supplied in Great Britain, confirm the applicable machinery safety assessment, conformity marking, declaration of conformity and instruction-language requirements with the relevant authority. Ensure the technical file is compiled and available on request. Match the documentation to the actual feeder configuration before shipment.

Worked duty example

Illustrative example, not a quote: Illustrative batch of automatic screw feeders for an assembly workshop, not a quotation under 8479 89 97 90, invoiced at £8,000 free on board, with £1,200 of freight and insurance to the UK. The customs value is £9,200. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £9,200, so it is £1,840. 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

Screw compatibility: run the production screws through the supplied track and escapement, checking head orientation, pickup position and surface damage.

Feed reliability: test replenishment, low hopper fill, stop and restart, and recovery from a jam; record missed and doubled deliveries against the agreed acceptance criteria.

Interface and safety: check the tube, nozzle and control signals with the intended driver; inspect guarding and maintenance isolation, and test the fitted safety functions.

Arrival and documents: inspect transit damage and displaced track settings, repeat the feed trial, and match the nameplate, conformity declaration, English instructions and supplied spares. Plan the factory trial through quality inspection.

What goes wrong

A demonstration with the supplier's screws can conceal incompatibility with your head geometry, coating or length variation. Screws can bridge in the hopper, overlap on the track or catch at the escapement. A feeder may deliver reliably on the bench yet fail when connected to the production tube or driver.

Treat a change in screw supplier or finish as a reason to repeat the agreed trial. Record the accepted track settings and changeover procedure. Resolve mismatched documentation, missing guards and unreliable jam recovery before shipment, then check that transport has not disturbed the setup.
