Sourcing ultrasonic gas meters from China

Zero duty on ultrasonic gas meters

Heading 9028 covers gas, liquid and electricity supply or production meters, including calibrating meters. Complete ultrasonic gas meters fall within the gas-meter line. The table repeats that line for different applications; these are not separate tariff subdivisions. Parts and accessories other than those for electricity meters have a separate line.

Read from the UK Trade Tariff on 1 October 2026, complete gas meters and the listed non-electricity meter parts carried 0% duty for goods from China. The supplied tariff record lists no anti-dumping or countervailing duty, suspensions or attached import controls for these lines.

Confirm the commodity code against the complete product description, particularly for separately supplied transducers, conversion devices and communications units. For the wider gas-meter heading, see rotary gas meters.

Specify the gas and measurement conditions

Tell the factory whether the meter is for billing or process monitoring. Specify the gas composition, flow range, operating pressure and temperature, connection type, installation orientation and permitted pressure loss. Agree whether the displayed volume is measured at operating conditions or converted to reference conditions, and which conversion inputs are supplied.

For regulated uses, confirm the applicable conformity assessment and conformity and metrology marking requirements under the Measuring Instruments Regulations with the relevant authority before market placement. Check the assessment route, accuracy class and model coverage with the factory. Both CE and UKCA marked meters can be placed on the Great Britain market. Arrange testing and certification checks against the intended use.

Specify the ultrasonic measurement arrangement, diagnostic outputs, battery replacement method and communications protocol. Ask for calibration results for the agreed gas and conditions. For supplier-installed smart meters, agree the applicable government smart metering equipment specification before sampling.

Worked duty example

Illustrative example, not a quote: A commercial batch of ultrasonic gas meters for a small metering business (illustrative) under 9028 10 00 00, invoiced at £45,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £47,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £47,000, so it is £9,400. 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

Identity and evidence: match the supplied model, serial numbers, accuracy class and applicable conformity and metrology markings to the assessment documents during inspection.

Measurement: test samples on a calibrated bench across the agreed flow range, including low flow, and compare performance at different temperatures. Check the displayed total against the recorded output.

Gas path and connections: inspect connection dimensions, sealing faces, flow direction and transit damage. Obtain leak-test records and check that protective caps kept debris out of the meter.

Power and communications: check battery condition, display, diagnostic messages, tamper seals and data transfer to the buyer's actual receiving system. Confirm that configuration settings match the approved sample.

What goes wrong

A meter can pass a factory test yet give unsuitable readings when the test gas, temperature, installation arrangement or volume reference differs from the buyer's application. Request the test conditions with the results, and compare samples under the intended conditions before accepting the production batch.

Other problems include documents covering a different model, damaged sealing faces, removable tamper seals and communications that work with the factory's reader but fail with the buyer's system. Put model identification, leak checks, configuration and data transfer into the purchase specification.
