Sourcing optical tachometers from China

UK duty on optical tachometers

Heading 9029 covers counters, speed indicators, tachometers and stroboscopes. Noncontact optical tachometers measure rotational speed without touching the shaft. The relevant starting point is 9029 20 38 90, other speed indicators and tachometers. The table also identifies related counters, stroboscopes and parts; these are distinct goods, not interchangeable descriptions.

Read from the UK Trade Tariff on 30 September 2026, all supplied lines carried 0% duty for goods from China. The supplied data records no anti-dumping or countervailing measures, suspensions or attached import controls. Import VAT is normally 20%; see import duty and VAT.

Confirm the commodity code using the instrument's function, whether it displays speed or accumulated revolutions, and whether it is a complete instrument or a part. For other products in this heading, see counters and speedometers.

Specify the optical measurement setup

Specify the speed range, accuracy, resolution, reading update behaviour, working distance and target size in the purchase specification. State whether the instrument uses a laser or another light source, needs reflective tape, stores readings or exports data. Agree how the factory will compare readings with a reference instrument across the intended operating range.

For electronic models within electromagnetic compatibility rules, the importer must check the manufacturer's conformity assessment and provide importer identification. Ask for model-matched documents and arrange a review through testing and certification. UK laser safety guidance says laser products sold in the UK should be classified in accordance with British standards.

Confirm with the relevant authority which waste electrical and battery producer responsibilities apply to electronic and battery models. Review these through the WEEE importer guide. Agree the battery arrangement, supplied accessories, instructions and replacement reflective tape before approving a sample.

Worked duty example

Illustrative example, not a quote: Illustrative small-business stock order of handheld optical tachometers under 9029 20 38 90, invoiced at £10,000 free on board, with £900 of freight and insurance to the UK. The customs value is £10,900. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £10,900, so it is £2,180. 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

Accuracy: compare sampled instruments with a reference at agreed speeds, using the specified target and distance; record unstable readings and deviations.

Optical pickup: check acquisition under the intended lighting, at different angles and distances, and with the supplied reflective tape.

Controls and power: check trigger operation, display readability, memory functions, battery contacts and any data connection.

Documents and packing: match the model to the supplied conformity documents and laser classification information; check instructions, accessories and protection of the optical window.

What goes wrong

Extra reflective patches or shiny surfaces can produce misleading readings. Poor tape adhesion, a dirty optical window or unsuitable aiming distance can cause intermittent pickup. A display that appears stable can still show the wrong speed, so repeat the reference comparison using the agreed target arrangement.

A supplier may substitute the sensor, electronics or battery arrangement after sample approval. Match production units to the approved specification and request a document review when the design changes. A report bearing a similar product photograph is insufficient evidence that it covers the delivered model.
