Sourcing ignition coils from China
Ignition coils from China carry 2% UK duty, or 0% where a specific suspension applies. Confirm the applicable product safety requirements and importer responsibilities with the relevant authority. Match the engine application, connector and electrical behaviour before ordering. Cambridge China Bridge sources ignition coils.
Ignition coil duty and conditional suspensions
Read from the UK Trade Tariff on 17 October 2026, heading 8511 includes ignition coils alongside other ignition and starting equipment. Ordinary replacement coils fall under 8511 30 00 90 at 2% duty from China. The supplied tariff record lists no anti-dumping or countervailing measures for the selected lines. See the wider ignition and starting equipment guide for other products in this heading.
The listed integrated igniter assembly under 8511 30 00 30 has a 0% suspension. Specified coils for manufacturing vehicle engines under 8511 30 00 55 have a 0% suspension subject to authorised-use customs supervision. Neither relief applies automatically to every coil. The tariff attaches a supplementary-unit import measure to 8511 30 00 30: check the required measurement or quantity with your customs broker before declaring goods from China.
Confirm the commodity code against the complete description, dimensions, electrical ratings and intended use. Have your broker check the suspension conditions against the actual assembly rather than its catalogue name. Separately imported coil parts need their own classification.
| Goods | Commodity code | Duty | Anti-dumping or countervailing duty on China |
|---|---|---|---|
| Other ignition coils | 8511 30 00 90 | 2% | None |
| Integrated igniter coil-on-plug assemblies meeting the listed specification | 8511 30 00 30 | 2% | None |
| Specified ignition coils for manufacturing motor vehicle engines | 8511 30 00 55 | 2% | None |
| Other parts of ignition equipment, including separately classified coil parts | 8511 90 00 90 | 2% | None |
Specify the coil and engine application
Give the factory an engine application list, reference part numbers and an approved physical sample. Specify whether the order is for individual coil-on-plug units or a coil pack, whether the igniter is integrated, and the connector pin layout. Record mounting positions, boot length, plug contact arrangement, supply voltage and the required operating temperature range.
Agree a coil-test procedure covering secondary output and insulation, including the test equipment, operating conditions and acceptance criteria. Ask for results tied to the supplied part number. Confirm the applicable product safety requirements and importer responsibilities for replacement ignition parts with the relevant authority. Use testing and certification support to settle the evidence needed for your application.
Worked duty example
Illustrative example, not a quote: 2,000 ignition coils, illustrative order under 8511 30 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 the connector keying, pin layout, mounting holes, boot and plug contact with the approved sample and engine application.
Electrical performance: test sampled coils for secondary output and insulation using the agreed conditions; compare results across the production batch.
Construction: inspect housings, potting, boots and terminals for cracks, voids, loose contacts or damage from packing.
Identification: check part numbers, batch references and box contents against the order. Reject unauthorised third-party trade marks. Arrange inspection by part number rather than treating mixed coils as one product.

What goes wrong
A similar housing can hide a different connector layout, igniter arrangement or boot length. The coil may appear to fit while its electrical behaviour differs from the approved sample. Weak insulation, cracked boots or loose contacts can cause intermittent misfiring. Check performance under the agreed operating conditions as well as physical fit.
A factory's claim that every coil is duty-free can also distort the landed cost. Compare the actual goods with the suspension description and resolve authorised-use conditions before shipment. Cross-reference numbers may describe fitment, but check the packaging presentation with the relevant authority if it could suggest the coil was made by another brand.

Frequently asked questions
What is the UK import duty on ignition coils from China?
Ordinary ignition coils carry 2% duty. Listed assemblies and specified engine-manufacturing coils can receive 0% under conditional suspensions. The supplied tariff record lists no anti-dumping or countervailing measures.
Are all coil-on-plug ignition coils duty-free?
No. The suspension under 8511 30 00 30 applies to the listed integrated igniter assembly specification. Other replacement coils generally fall under 8511 30 00 90 at 2%.
What should I ask a Chinese ignition coil factory to test?
Ask for secondary-output and insulation tests under agreed operating conditions, with results tied to the part number. Check connector layout, mounting, boots and plug contacts against an approved sample.
Can I put vehicle brand part numbers on ignition coil boxes?
Cross-reference numbers can show fitment, but check the presentation with the relevant authority if it could imply manufacture by that brand. Do not accept coils or packaging carrying another company's trade mark without permission.
