Sourcing aggregate log washers from China

Zero duty on log washers and their parts

Heading 8474 covers machinery for processing solid mineral materials. Aggregate log washers scrub stone in a water-filled trough using rotating shafts and paddles. Washing machines fall under 8474 10 00 00; separately imported parts have their own lines. The table includes companion screens and parts, rather than treating every item as a complete washer.

Read from the UK Trade Tariff on 30 September 2026, all supplied lines carried 0% duty for goods from China. The snapshot records no anti-dumping or countervailing duties, suspensions or attached import controls. These tariff findings do not replace machinery safety checks.

Confirm the commodity code against the machine's function, assembly drawings and separately shipped components. For the surrounding plant, see aggregate washing plants.

Specify clay removal and the complete drive

Describe the stone type, feed grading, clay content and whether clay arrives as sticky lumps or loose fines. Agree the required cleaned product and throughput using representative feed. Specify trough dimensions, shaft arrangement, paddle layout, shaft speed, drive power, water supply, overflow position and discharge height.

Record paddle and liner materials, replacement method, bearing and gearbox specifications, shaft seals, lubrication access and spare-part drawings. Agree support loads and connections to neighbouring equipment. Trial the washer with material close to yours and record clay removal, stone loss, water use and drive behaviour.

For new machinery placed on the Great Britain market, UKCA or CE marking, a declaration of conformity and English instructions are required. Ask for these for the supplied configuration, and check guarding, emergency stops and isolation arrangements before shipment.

Worked duty example

Illustrative example, not a quote: An electric aggregate log washer, illustrative order only under 8474 10 00 00, invoiced at £32,000 free on board, with £6,000 of freight and insurance to the UK. The customs value is £38,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £38,000, so it is £7,600. 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

Trough and shafts: inspect welds, shaft alignment, paddle spacing, liner fixing and drain access against approved drawings; check for transport distortion on arrival.

Wear components: compare paddle and liner materials with the order, inspect fastening and replacement access, and match delivered spares to the parts drawings.

Drive and seals: verify motor, gearbox and bearings against the specification; during an agreed run, check for vibration, overheating, leakage and lubricant contamination.

Safety and documents: check guards, emergency stops and isolation; match the machine identity to its declaration, marking and English manual. Use an agreed inspection brief.

What goes wrong

A trial with clean gravel can hide poor clay removal on sticky feed. Worn paddles reduce scrubbing, abrasive slurry damages seals, and misaligned shafts can overload bearings and the drive. Check the cleaned stone and rejected material together so that apparent cleaning does not conceal excessive stone loss.

Installation problems arise when discharge height, support positions or water connections differ from the plant drawings. Agree interfaces before manufacture, preserve trial records and inspect transport damage before assembly. Set acceptance criteria around your feed and cleaned product rather than the supplier's general capacity claim.
