Tariff classification of CNG dispensers turns on whether the device pumps fuel or automatically regulates flow and pressure.

A CNG dispenser was examined for tariff classification under Heading 8413 as a pump for dispensing fuel, or under Heading 9032 as an automatic regulating or controlling apparatus. The analysis found that a pump must use external force, such as pressure or suction, to raise, transfer, deliver, or compress fluid or gas. On the facts, the dispenser did not itself operate as a pumping mechanism; gas flowed due to pressure difference between the station and the vehicle tank. It did, however, use a pressure sensor, controller, and actuating mechanism to measure, regulate, and cut off dispensing automatically when the preset value was reached. The dispenser was therefore correctly classified under Heading 9032, not Heading 8413.

Issues: Whether the CNG dispenser was classifiable as a pump for dispensing fuel under Heading 8413, or as an automatic regulating or controlling instrument and apparatus under Heading 9032.

Analysis: The relevant tariff entry for Heading 8413 covers pumps for dispensing fuel or lubricants of the type used in filling stations or garages. The ordinary meaning of a pump, the Customs Tariff heading, and the explanatory notes show that the essential feature is the use of external force, such as pressure or suction, to raise, transfer, deliver, or compress fluids or gases. On the facts found, the CNG dispenser did not itself use pressure or suction as a pumping mechanism; the gas flowed because of pressure difference between the station and the vehicle tank. The device therefore did not satisfy the primary requirement of a pump. By contrast, Chapter Note 7 to Heading 9032 applies to apparatus that automatically control flow or pressure by measuring the variable, comparing it with the desired value, and actuating a starting, stopping, or operating device. The CNG dispenser had a pressure sensor, controller unit, and actuating mechanism that automatically measured and regulated the dispensing of gas and cut off supply when the preset value was reached. It therefore satisfied the requirements of an automatic control apparatus.

Conclusion: The CNG dispenser was not classifiable under Heading 8413 and was correctly classifiable under Heading 9032.

Ratio Decidendi: Where a dispensing device does not itself operate as a pump by using external force to transfer fluid or gas, but instead automatically measures and regulates flow or pressure through sensing, control, and actuation, it falls under the tariff heading for automatic regulating or controlling apparatus rather than the heading for pumps.
