U.S. imports of parts & accessories for liquid & gas measuring instruments (HS 902690) totaled $64.8M in April 2026, traded with 60 countries.
Importers of Parts & Accessories for Liquid & Gas Measuring Instruments paid $5.3M in duties in April 2026 — an effective duty rate of 13% on $41.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReplacement and aftermarket components for flow meters, pressure gauges, level sensors, and heat meters fall under this heading, making it a high-volume category for MRO procurement in the energy, chemical, and water-utility sectors. The US schedule separates parts for electrical instruments (9026902000), parts for flow and heat meters (9026904000), and other non-electrical parts (9026906000). Mexico and Germany are the leading sources, with Switzerland — home to several precision-instrument manufacturers — also a notable supplier. Correct parts classification requires linking the component back to the parent instrument's heading, and misidentification of a subassembly as a finished instrument is a common entry error.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A printed circuit board assembly that is identifiable as solely or principally used in a pressure measuring instrument of heading 9026 should classify as a part under 9026902000 (for electrical instrument parts) rather than as a standalone electronic assembly under Chapter 85. The key is demonstrating dedicated use through technical documentation or the manufacturer's bill of materials.
Yes. Parts classified under heading 9026.90 that originate in China are generally subject to Section 301 tariffs. Importers should verify the applicable Section 301 list for the specific 10-digit subheading, as coverage and rates can differ across product lines within the heading.
