Sourcing vehicle alternators from China
Vehicle alternators and the selected alternator parts from China carry 2% UK duty, with no duty variation across these lines. Replacement units must be safe, with product safety responsibility resting on the importer. Specify vehicle fitment, regulator compatibility and tested output before ordering. Cambridge China Bridge sources vehicle alternators.
UK duty on vehicle alternators
Read from the UK Trade Tariff on 18 October 2026, complete vehicle alternators under 8511 50 00 90 carried 2% duty for goods from China. Heading 8511 covers generators used with internal combustion engines alongside ignition and starting equipment. The selected alternator parts also carried 2%, with no anti-dumping or countervailing measures, suspensions or attached import controls recorded for these lines.
The table separates passenger-car and commercial-vehicle applications under the same complete-alternator code. The drive end shield line applies only to its listed manufacturing and material specification. Confirm each commodity code against the actual product description. For adjacent products, see spark plugs and starter motors.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Passenger-car alternators | 8511 50 00 90 | 2% | None |
| Alternator drive end shields meeting the listed casting specification | 8511 90 00 20 | 2% | None |
| Other alternator parts | 8511 90 00 90 | 2% | None |
Specify alternator fitment and charging output
Give the factory the vehicle application, engine variant and reference part number, supported by a drawing or approved sample. Specify mounting positions, pulley profile and alignment, rotation, connector layout, regulator compatibility, rated voltage and output current. Agree the output test conditions rather than accepting a rating printed on the box.
State whether units are new or remanufactured. Describe remanufactured alternators clearly as remanufactured and confirm any applicable sales-description requirements with the relevant authority; agree core return terms before ordering. Replacement parts must be safe, and the importer carries that responsibility. Once a product has been placed on the market, the business remains responsible for its safety.
Worked duty example
Illustrative example, not a quote: 2,000 vehicle alternators across assorted replacement part numbers, illustrative only under 8511 50 00 90, invoiced at £60,000 free on board, with £3,000 of freight and insurance to the UK. The customs value is £63,000. Duty at 2% is £1,260. Import VAT at 20% is charged on the customs value plus duty, £64,260, so it is £12,852. Import taxes total £14,112; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £1,260 of duty. The import duty and VAT guide explains each step.
Inspection checklist
Fitment: compare mounting holes, pulley alignment, connector shape and terminal positions with the approved sample and vehicle cross-reference.
Charging: bench-test output current against speed using the agreed ISO 8854 method, and check regulator voltage and compatibility with the intended vehicle.
Condition: check bearing noise, pulley movement, housing cracks and terminal damage; compare supplied units with the agreed new or remanufactured condition.
Identification: check part numbers, cross-reference lists, agreed branding and protective packaging. Sample each part number during quality inspection.

What goes wrong
An alternator can bolt into place yet have an incompatible regulator or connector. Wrong regulator settings and weak bearings are known failure points. A box label cannot establish charging performance: compare the supplied units with the approved sample and retain the bench-test results.
Mixed part numbers can hide fitment errors within a shipment. Keep applications separate during inspection and agree how the supplier will handle failed units. Cross-reference numbers may describe fitment, but check the packaging presentation with the relevant authority if it could suggest that the alternator was made by another brand.

Frequently asked questions
What is the UK import duty on vehicle alternators from China?
The supplied tariff data shows 2% for complete alternators and the selected alternator parts, with no anti-dumping or countervailing duty.
How do I check an alternator will fit my vehicle?
Match the vehicle application and reference part number, then compare mounting positions, pulley alignment, connector layout and regulator compatibility with an approved sample.
What tests should I request from the factory?
Request output current against speed, regulator voltage checks and bearing checks under agreed conditions. Use ISO 8854 for the agreed alternator output test method.
Can I import remanufactured alternators?
Specify their condition clearly. Describe remanufactured units as remanufactured and confirm any applicable sales-description requirements with the relevant authority, with core return terms agreed. Check condition and charging performance against the approved sample.
