Sourcing heat meters from China

Zero duty on heat meters

Heading 9026 expressly includes heat meters. The table distinguishes complete electronic and non-electronic instruments, separately supplied electronic liquid flow meters, and parts. A complete heat meter measures heat rather than just liquid flow; describe the complete assembly when confirming its classification.

Read from the UK Trade Tariff on 30 September 2026, the selected lines carried 0% duty for goods from China, with no listed anti-dumping or countervailing duty, suspensions or attached import controls. The wider heading's pressure-instrument lines have a mercury import control attached; if these are included in your shipment, confirm the requirement with your customs broker.

Confirm the commodity code using the technical description and whether the shipment contains complete meters or separate components. See the flow meters and pressure gauges guide for the wider heading.

Specify the heat-meter assembly and installation

Specify heating or cooling use, the heat-transfer liquid, flow range, temperature range and temperature difference, installation position, pipe connections and pressure rating. Agree the matched temperature probes, pockets, cable lengths, calculator, power supply and reading interface. Ask for calibration evidence covering the assembled meter's intended operating conditions, and test sample data with your actual reading system.

Confirm with the relevant authority whether the Electromagnetic Compatibility Regulations apply to electronic equipment liable to generate electromagnetic disturbance, and whether the Radio Equipment Regulations apply to wireless models. Request model-specific declarations and supporting reports through testing and certification. For products potentially within the hazardous-substance rules, confirm with the relevant authority whether and where the importer’s name or trademark and contactable address must appear.

Confirm the applicable heat-network regulatory requirements in Great Britain with Ofgem. Agree the proposed meter's suitability for billing with the network operator before ordering, including how readings reach its billing system. Check with the relevant authority whether your business is an electrical-equipment producer and what registration or renewal requirements apply.

Worked duty example

Illustrative example, not a quote: Illustrative order: 100 electronic heat meters under 9026 80 20 00, 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

Assembly: match the meter, calculator and paired temperature probes to the approved specification; check serial numbers against calibration records.

Measurement: compare flow, temperatures and accumulated heat against reference measurements under the agreed test conditions; check the displayed units and exported readings.

Installation: check connection threads, installation length, flow-direction marking, probe pockets, cable condition and seals; test for leakage at the agreed conditions.

Documents: match declarations and reports to the delivered model and reading interface; check importer details where required. Use quality inspection to organise the checks.

What goes wrong

Mismatched temperature probes, swapped supply and return positions, an unsuitable flow range or the wrong liquid setting can produce misleading heat readings. A working display does not prove that the complete assembly measures correctly. Test the supplied combination rather than accepting separate component certificates as the whole test.

A reading interface can work with the factory's software yet fail with the buyer's gateway or billing platform. Connection dimensions and probe pockets can also differ from the approved sample. Record the accepted configuration and repeat the agreed functional and fit checks on arrival.
