Ultrasonic flow meter classification: measurementonly gas flowmeters fall under tariff heading for measuring instruments, not automatic control.

An ultrasonic flowmeter designed solely to measure gas flow and incapable of automatic regulation is classifiable as a measuring instrument under Heading 9026; therefore it falls under the residual eightdigit subheading for other flowmeters. The classification rests on the device's measurement-only function and on interpreting tariff headings and Explanatory Notes so that instruments specifically covered by one heading are not reclassified as automatic control apparatus when imported standalone. If the same device is imported together with starting, stopping or control components as a complete automatic control apparatus, it may instead qualify under the heading for automatic regulating instruments.

Issues: Whether the ultrasonic flow meters (DigitalFlow GC868, DigitalFlow GF868, PanaFlow and TransPort PT878GC) are classifiable under CTI 9026 80 90 of the First Schedule to the Customs Tariff Act, 1975 as instruments for measuring/checking flow of gases, or alternatively under CTH 9032 as automatic regulating or controlling instruments.

Analysis: Applicable classification framework comprises GRI 1, Note 2(a) and Note 7 to Chapter 90, and the Explanatory Notes to Headings 9026 and 9032. Heading 9026 covers instruments and apparatus for measuring or checking flow of liquids or gases, including devices using ultrasound, and permits instruments fitted with transmitters or signalling devices. Heading 9032 covers automatic regulating or controlling apparatus which, in their imported condition, must perform the integrated functions of (a) measuring the variable, (b) comparing measured values with desired values, and (c) actuating starting/stopping/operating devices to restore or maintain the variable. The decisive factual/legal test is whether the goods, as imported, perform only the measuring function or additionally perform the comparison and actuation functions that constitute automatic control apparatus. The subject products operate on transit-time ultrasonic principles to measure gas flow and, in some models, convert and transmit measurement data via MODBUS/HART/Foundation Fieldbus to external systems. The products are not imported with valves, actuators, controllers, or starting/stopping devices and do not themselves compare measured values with setpoints or directly actuate control devices. Note 2(a) to Chapter 90 directs that parts and accessories which are goods included in any heading of Chapter 90 are to be classified in their respective headings even when used in larger systems. The communication capability of certain models is limited to transmission of measurement data and does not convert the goods into automatic regulating apparatus in their as-imported condition. The TransPort PT878GC lacks even the data-transmission capability and functions solely as a standalone measuring instrument.

Conclusion: The ultrasonic flow meters DigitalFlow GC868, DigitalFlow GF868, PanaFlow and TransPort PT878GC are classifiable under CTI 9026 80 90 of the First Schedule to the Customs Tariff Act, 1975. The ruling is in favour of the appellant.
