In re GE Oil & Gas India Private Limited (CAAR Mumbai)
Classification of Ultrasonic Flow Meter intended for liquid applications, bearing model no. (i) AquaTrans AT600 (ii) PanaFlow LC (iii) PanaFlow LZ (iv) PanaFlow HT (v) TransPort PT900 & (vi) PanaFlow Z3.
Background & Issue
GE Oil & Gas India petitioned the Customs Appellate Authority for Advance Rulings (CAAR) in Mumbai over the tariff classification of six ultrasonic flow meter models—AquaTrans AT600, PanaFlow LC, LZ, HT, Z3, and TransPort PT900. The central question was whether these devices qualify as:
-
Automatic regulating/controlling instruments under Customs Tariff Heading (CTH) 9032, or
-
Measurement instruments under CTH 9026.
This distinction affects duty treatment upon import.
Legal Framework
-
Section 28H(2) Customs Act, 1962 governs classification rulings
-
Customs Tariff Act, 1975 and General Rules of Interpretation (GRIs) stipulate classification starts from the heading’s literal description, aided by section and chapter notes
Two pertinent headings:
-
CTH 9032 – “Automatic Regulating or Controlling Instruments and Apparatus.” Per Chapter 90 Note 7, such instruments must:
-
measure a variable,
-
compare it with a setpoint,
-
actuate a mechanism to adjust/control automatically.
They may be standalone or functional units with control systems incorporated.
-
-
CTH 9026 – “Instruments and apparatus for measuring or checking the flow… for example, flowmeters.” Excludes items in headings 9014, 9015, 9028, 9032. Arguably the appropriate fallback category for simple flowmeters.
Technical Features of the Devices
-
All six models are ultrasonic transit‑time flow meters designed to measure liquid flow in open or closed conduits.
-
They output data via LCD displays and communication protocols (MODBUS, HART, Fieldbus).
-
They transmit measurements, but do not:
