Sourcing Coriolis Mass Flow Meters from China

Zero duty on the relevant meter lines

Heading 9026 covers instruments measuring or checking variables of liquids or gases. For Coriolis meters, distinguish electronic liquid flow meters from electronic gas flow instruments and separately supplied parts. The other gas-instrument line is included for classification comparison, rather than as the default for an electronic Coriolis meter.

Read from the UK Trade Tariff on 30 September 2026, the selected lines carried 0% duty for goods from China. No anti-dumping duty, countervailing duty, suspension or attached import control was recorded for these lines. Mercury controls appear on pressure-instrument lines elsewhere in the heading, rather than the selected flow-meter lines.

Confirm the commodity code using the medium, measuring function, electronic construction and whether the shipment contains complete meters or parts. See the turbine flow meter guide for wider heading context.

Specify the measuring tube and operating conditions

State the liquid or gas, normal and extreme flow conditions, temperature, pressure, viscosity and any entrained gas or solids. Specify wetted materials, tube arrangement, process connections, permitted pressure loss and installation space. Ask the supplier to explain the zero-setting procedure and mounting arrangement for your pipework.

Agree mass-flow accuracy across the operating range, repeatability, density measurement if required, totaliser behaviour and output compatibility with your control system. Request calibration records matched to each serial number and covering the range you will use.

Electrical and electronic equipment liable to generate electromagnetic disturbance falls within the electromagnetic compatibility regulations, subject to exceptions. For hazardous-area instruments, confirm the applicable explosive-atmosphere requirements with the relevant authority. For meters measuring liquids for sale, ask the relevant authority whether the Measuring Instruments Regulations apply and whether conformity assessment is needed. Settle the intended use and documents before ordering.

Worked duty example

Illustrative example, not a quote: Illustrative batch of Coriolis liquid mass flow meters under 9026 10 21 00, invoiced at £96,000 free on board, with £3,500 of freight and insurance to the UK. The customs value is £99,500. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £99,500, so it is £19,900. 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: match sensor, transmitter and calibration records to the ordered model and serial numbers; check the supplied configuration and display units.

Measurement: check zero stability with the tube filled and flow stopped, then compare mass-flow readings and totalised mass with a suitable reference across the agreed operating range.

Mechanical condition: inspect measuring tubes, connections and sealing faces for damage; check connection dimensions, wetted-material records and agreed leak-test results.

Documents and outputs: check hazardous-area documents against the model and marking where applicable; test signal transmission, alarms and totaliser settings during inspection.

What goes wrong

A meter selected only by connection size can be unsuitable for the actual flow range or pressure-loss allowance. Entrained gas, pipe vibration, mounting stress or an unsuitable zero-setting procedure can undermine readings. Ask for an application review and test the sample under conditions representative of your process.

Sensor and transmitter substitutions can leave calibration records or hazardous-area documents mismatched. Incorrect output scaling can produce plausible display readings but wrong control-system values. Freeze the approved configuration and compare the delivered assembly, documents and transmitted readings before release.
