SITCSection 8
U.S. imports of liquid meters (SITC 87313) totaled $21.2M in April 2026, traded with 24 countries.
Importers of Liquid Meters paid $944K in duties in April 2026 — an effective duty rate of 12% on $7.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataLiquid meters encompass a broad range of flow-measurement instruments — positive-displacement, turbine, electromagnetic, ultrasonic, and Coriolis types — used across petroleum distribution, water utilities, chemical processing, and food and beverage production. The choice of meter technology is driven by fluid viscosity, flow rate, and required accuracy class, making specification alignment between foreign manufacturer and end-user a critical procurement step. Custody-transfer meters used in petroleum trade are subject to API MPMS (Manual of Petroleum Measurement Standards) accuracy requirements, and utility water meters must meet AWWA standards and state weights-and-measures approval, paralleling the regulatory framework applicable to gas meters.

Custody-transfer meters are used at points where ownership of a liquid commodity — crude oil, refined products, LNG — changes hands, and they must meet stringent accuracy standards (typically API MPMS or OIML R117) with documented calibration traceability. General-purpose flow meters used for process monitoring or internal accounting do not carry the same legal-for-trade requirements. Importers supplying custody-transfer applications should obtain calibration certificates and type-approval documentation from the foreign manufacturer before shipment.
In practice, utility billing meters and industrial process meters are distinct product lines. Utility water meters must meet AWWA standards and receive state weights-and-measures approval for legal-for-trade use; industrial process meters are selected for chemical compatibility, pressure rating, and accuracy class rather than regulatory approval. A meter approved for utility billing can technically be used in a process application, but the reverse is generally not permissible for billing purposes without formal type approval.
