Sourcing spark plugs and starter motors from China
Spark plugs, magnetos, distributors, ignition coils, starter motors, alternators and parts from China pay 2% UK duty, with no anti-dumping duty. No type approval is needed for these replacement parts, but they must be safe, and counterfeit branded plugs are a common trap. Fitment data and bench tests matter. Cambridge China Bridge sources ignition and starting parts for UK and overseas buyers.
Spark plugs, ignition coils, starter motors and alternators pay 2% UK duty from China. Brand marks, fitment and remanufacturing explained.

Duty at 2%
Read from the UK Trade Tariff on 25 September 2026, sparking plugs, ignition magnetos and magnetic flywheels, distributors and ignition coils, starter motors and starter-generators, other generators such as alternators, other ignition and starting equipment, and parts carried 2% duty on goods from China, with no anti-dumping measure.
Some specific coil and module designs have their own codes at the same rate; confirm the commodity code for each part.

Brands and counterfeits
Plugs and coils sold under well-known brand names are among the most counterfeited car parts. Buy under your own brand or from the brand's authorised channel, and never accept goods carrying another company's mark without its permission; the IP guide explains why seizures fall on the importer.
Cross-reference part numbers can be quoted for fitment, but should not be printed in a way that suggests the part is made by that brand.
Safety and fitment
These parts do not need type approval when sold as replacements, but they must be safe under UK product safety law, and that duty sits with the importer of record. Ask for heat range, thread and reach for plugs, and voltage, output current, pinion teeth and mounting for starters and alternators.
Remanufactured starters and alternators must be sold as remanufactured, with the core return terms agreed.
Bench tests and inspection
Bench-test starters and alternators on samples for current draw and output, and check plug gap and insulation. At inspection, sample by part number and check boxes, labels and cross-reference lists.
