Sourcing Vernier height gauges from China

2% duty on Vernier height gauges

Read from the UK Trade Tariff on 30 September 2026, heading 9017 covers drawing, marking-out and calculating instruments and specified length-measuring instruments. Mechanical Vernier height gauges normally belong in the micrometers, callipers and gauges line, 9017 30 00 00, carrying 2% duty on goods from China.

The supplied record shows no anti-dumping or countervailing duty, suspension or attached import control for the listed lines. The table includes neighbouring classification lines and separately imported parts; these are not interchangeable codes for a complete height gauge.

Confirm the commodity code using the instrument's construction, measuring function and supplied accessories. See the micrometers guide for the wider heading.

Specify the beam, base and scriber

Specify a mechanical Vernier model, measuring range, scale units, scale resolution and permitted indication error. Include base dimensions, beam construction, fine adjustment, carriage lock and the scriber's material and mounting. State whether the protective case and replacement scriber are included.

Agree checks on a calibrated surface plate with reference blocks, including readings across the usable range and repeated readings after moving the carriage. Request calibration results matched to each instrument's serial number. Employers providing equipment for use at work need arrangements to maintain it safely; calibration checks should be agreed separately.

Worked duty example

Illustrative example, not a quote: Illustrative order: 10 Vernier height gauges under 9017 30 00 00, invoiced at £3,000 free on board, with £860 of freight and insurance to the UK. The customs value is £3,860. Duty at 2% is £77.20. Import VAT at 20% is charged on the customs value plus duty, £3,937.20, so it is £787.44. Import taxes total £864.64; a VAT-registered importer can usually reclaim the VAT, so the lasting cost is the £77.20 of duty. The import duty and VAT guide explains each step.

Inspection checklist

Base: check for rocking on a clean reference plate, burrs underneath, corrosion and damage to the contact surface.

Readings: compare indications with calibrated reference blocks across the range, repeat after carriage movement and check whether locking changes the reading.

Carriage and scriber: check smooth travel, fine adjustment, clamp security, scriber seating and the condition of the contact edge.

Identification and packing: match serial numbers to calibration results, check legible graduations and confirm the case restrains the base and protects the scriber.

What goes wrong

A fine scale division does not establish measurement accuracy. A rocking base, loose carriage or poorly seated scriber can give inconsistent readings even when the scale looks clear. Agree acceptance limits and the measuring setup before approving the sample.

Transit damage and corrosion can spoil an accepted instrument. Compare arrival checks with the factory results before releasing stock, and investigate any shift rather than adjusting the zero to conceal it.
