U.S. imports of instruments for measuring or checking other variables of liquids or gases (HS 902680) totaled $36.8M in April 2026, traded with 52 countries.
Importers of Instruments for Measuring or Checking Other Variables of Liquids or Gases paid $3.2M in duties in April 2026 — an effective duty rate of 12% on $27.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataBeyond pressure, this heading captures instruments that measure flow, level, temperature, viscosity, and other physical variables of liquids or gases — critical inputs for utilities, petrochemicals, food processing, and water treatment. The US tariff schedule distinguishes electrical instruments (9026802000), heat meters incorporating liquid supply meters (9026804000), and non-electrical types (9026806000), each potentially carrying different duty rates. Germany leads US import supply under this heading, with Mexico and Japan also significant sources. Heat meters in particular are subject to close scrutiny at classification because they may overlap with metering equipment in Chapter 90 or utility-grade instruments governed by NIST traceability requirements.

Subheading 9026804000 specifically covers combination units that integrate a heat-quantity calculator with a liquid flow meter — commonly used in district heating and cooling systems. Stand-alone heat calculators or flow meters without the combined function classify elsewhere in the heading or potentially under a different subheading. Documentation from the manufacturer confirming the integrated design is essential to support this classification.
Canada is among the top suppliers under this heading, and goods originating in Canada that meet USMCA rules of origin are eligible for preferential tariff treatment. Importers must ensure a valid USMCA certification of origin is on file and that the product satisfies the applicable tariff shift or regional value content requirement.
