Sourcing brushed DC motors from China

Duty and classification for brushed DC motors

Heading 8501 covers electric motors and generators, excluding generating sets. Brushed DC motors use brushes and a commutator; classify the actual motor or actuator by its output, construction and intended use. The table contains specialist descriptions that can cover brushed products, rather than interchangeable codes for any small motor.

Read from the UK Trade Tariff on 30 September 2026, the selected lines carried 0% duty for goods from China. The supplied records show no anti-dumping or countervailing duty, suspensions or attached import controls on these lines. Import VAT is separate from duty.

Match every condition in the full description before using a specialist line. Give your broker the datasheet, mechanical output, voltage and intended application to confirm the commodity code. For related products within the wider heading, see brushless DC motors. For induction motors, see our three-phase induction motor sourcing guide.

Specify brushes, torque and operating duty

Specify rated voltage, loaded speed and torque, starting current, operating duty and allowable temperature rise. Agree the brush material, commutator construction, bearing or bush type, suppression components and brush-life test conditions. Include shaft diameter, projection, mounting holes, connector polarity and any gearbox ratio. Test an approved sample in the intended mechanism, including repeated starts and reversals.

For Great Britain, confirm the electrical safety scope for the motor's DC voltage and any technical documentation, declaration of conformity, CE or UKCA marking and importer identification requirements with the relevant authority. Where the electrical safety Regulations apply, the importer must ensure instructions are in easily understandable English. Electromagnetic compatibility rules cover equipment liable to generate electromagnetic disturbance, with exceptions; confirm scope for the supplied motor and assembly.

Worked duty example

Illustrative example, not a quote: Illustrative order of 400 brushed DC motors meeting the full line description under 8501 10 99 56, invoiced at £12,000 free on board, with £600 of freight and insurance to the UK. The customs value is £12,600. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £12,600, so it is £2,520. 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

Performance: measure loaded speed, torque, current and temperature rise using the agreed supply and duty cycle. Compare production samples with the approved sample.

Brushes and commutator: inspect brush seating, spring pressure and commutator finish. Run samples through the agreed endurance test and record wear, sparking and intermittent operation.

Fit and wiring: measure shaft and mounting dimensions, check shaft runout and bearing noise, and verify connector polarity and suppression components.

Arrival condition: check for bent shafts, corrosion, cracked brush holders and damaged terminals. Match batch identification and applicable documents to the delivered model; use the inspection guide.

What goes wrong

A motor can meet its no-load speed claim yet stall or overheat in the buyer's mechanism. Changed brush material, weak springs, rough commutators and substituted bearings can shorten service life. Fix acceptance criteria around the actual load and operating cycle, and retain an approved sample for comparison.

Brush sparking can disturb nearby electronics, so test the motor with the intended wiring and suppression components. A matching outer casing does not prove matching windings, torque or brush life. Do not treat a report for another motor rating as evidence for the delivered model.
