Sourcing starter motor solenoids from China
Starter motor solenoids imported from China under the other-parts line carry 2% UK duty, with no trade remedy or suspension listed. Replacement parts must be safe; confirm classification and match the solenoid to the actual starter, rather than relying on a vehicle list alone. Cambridge China Bridge sources starter motor solenoids.
UK duty on starter motor solenoids
Heading 8511 covers electrical ignition and starting equipment for internal combustion engines and its parts. For a separately supplied starter motor solenoid, 8511 90 00 90 is a candidate parts line, subject to confirmation. The table also shows complete starters and associated repair parts; those rows do not describe separate solenoids.
Read from the UK Trade Tariff on 30 September 2026, the other-parts line carries 2% duty for goods from China, with no anti-dumping or countervailing measure, suspension or attached import control listed. Complete starters also carry 2%, but their narrowly described motor-generator suspension should not be treated as a solenoid exemption.
Give your broker the assembly drawing, electrical function and details of whether the shipment contains separate solenoids or complete starters. Confirm the commodity code. See the wider ignition and starting equipment guide for other products in this heading.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other starting-equipment parts, candidate line for separate starter solenoids | 8511 90 00 90 | 2% | None |
| Complete starter motors supplied with solenoids | 8511 40 00 90 | 2% | None |
| Specified starter drive end shields, for associated repair orders | 8511 90 00 20 | 2% | None |
| Specified starter commutators, for associated repair orders | 8511 90 00 30 | 2% | None |
Specify the solenoid against the starter
Send the factory the starter manufacturer's reference, an approved sample and a dimensioned drawing. Specify mounting centres, flange shape, plunger travel, linkage engagement, terminal position and thread, connector shape, coil voltage and earthing arrangement. Agree contact material and electrical acceptance criteria rather than accepting an unexplained vehicle compatibility list.
Agree pull-in, hold-in and release tests on the intended starter assembly, including hot operation and repeated switching. Record the test conditions and acceptable results in the purchase specification. Replacement starting parts must be safe, as explained in the wider guide; importers placing products on the UK market need to demonstrate compliance with relevant safety requirements.
Worked duty example
Illustrative example, not a quote: Illustrative mixed-part-number order of 2,000 starter motor solenoids under 8511 90 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, plunger travel and linkage engagement with the approved sample; trial-fit samples to the intended starter.
Electrical operation: check pull-in, holding and release, coil resistance and contact voltage drop under the agreed test conditions.
Construction: inspect terminal security, contact alignment, insulation, seals and plunger movement; look for loose studs, cracks and binding.
Arrival and identification: check for corrosion, damaged terminals and mixed references; reconcile carton labels with the order and retain batch test records. Arrange inspection by part number.

What goes wrong
A solenoid may resemble the original but have a different plunger stroke, terminal arrangement or mounting position. The result can be poor engagement, an incompatible connection or failure to release. Weak contacts and sticking plungers can produce intermittent starting or overheating.
Settle failures against the approved sample and recorded test conditions. Ask the factory to identify the affected batches and explain the corrective action before accepting replacements. Use your own branding or an authorised supply channel; cross-reference information should not suggest manufacture by another brand.

Frequently asked questions
What is the UK import duty on starter solenoids from China?
The candidate other-parts line, 8511 90 00 90, carries 2% duty from China. The supplied tariff data lists no trade remedy or suspension on that line. Confirm classification for the actual product.
Can I order using only a vehicle compatibility list?
Ask for the actual starter reference, drawing and sample. Compare mounting, plunger travel, terminal layout and electrical operation on the intended starter before approving production.
Does the starter motor duty suspension cover separate solenoids?
The suspension on the complete-starter line is restricted to a described motor-generator. No suspension is listed on 8511 90 00 90; do not assume a separate solenoid qualifies.
What should I test before accepting a batch?
Check fit, pull-in, holding, release and contact voltage drop under agreed conditions. Include hot operation, terminal security and batch identification, using the approved sample as the comparison.
