U.S. imports of instruments for measuring voltage, current, resistance, or power — without recording device (nesoi) (HS 903033) totaled $47.8M in April 2026, traded with 67 countries.
Importers of Instruments for Measuring Voltage, Current, Resistance, or Power — Without Recording Device (NESOI) paid $4.1M in duties in April 2026 — an effective duty rate of 12% on $34.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataNon-recording instruments for measuring or checking voltage, current, resistance, and power form a workhorse category for electrical testing across industrial, utility, and electronics manufacturing sectors. The US schedule subdivides this heading into four 10-digit lines — covering voltage/current/resistance testers (9030330040), power-measuring apparatus (9030330080), dedicated resistance instruments (9030333400), and a residual NESOI line (9030333800) — allowing precise classification by measured parameter. Mexico is the leading supplier to the US market, with Germany, China, Taiwan, and Japan also significant sources. Goods of Chinese origin in this heading warrant a Section 301 tariff review prior to entry.

Classification follows the instrument's primary or predominant function. A device designed principally to measure power (watts, VA, power factor) belongs under 9030330080, while one focused on voltage, current, or resistance testing falls under 9030330040. When a single instrument performs all functions equally, the importer should consult the General Rules of Interpretation and, if needed, seek a binding ruling from CBP.
The presence or absence of a recording device is a classification criterion, not necessarily a duty-rate driver — both categories may carry the same general rate of duty. However, the distinction matters for correct tariff-line selection, and misclassification can trigger penalties. Always verify the current rate in the Harmonized Tariff Schedule, as rates can be modified by trade-remedy orders.
