HS Code 9030.39 – Instruments and apparatus; for measuring or checking voltage, current, resistance or power, with a recording device (excluding multimeters)
HS code 9030.39 is the 6-digit subheading for instruments and apparatus, for measuring or checking voltage, current, resistance or power, with a recording device (excluding multimeters). It is used for power quality analyzers, data logging voltmeters, recording ammeters, energy consumption recorders and resistance data loggers.
What HS 9030.39 covers
This HS code covers specialized instruments and apparatus designed for precisely measuring or checking electrical quantities like voltage, current, resistance, or power, crucially featuring a built-in recording device. Unlike simpler multimeters, these tools are engineered for continuous monitoring, data logging, and trend analysis over time. They are indispensable in industrial automation, power generation and distribution, electrical maintenance, and advanced research and development laboratories. Key users include utility companies monitoring grid stability, manufacturers performing quality control on electrical components, and engineers troubleshooting complex systems. The recording capability allows for historical data analysis, predictive maintenance, and compliance verification, making them vital for ensuring the reliability and efficiency of electrical infrastructure and equipment globally. Major importers and exporters are typically countries with robust industrial sectors and advanced technological infrastructure.

Codes often confused with 9030.39
Common mistake. This code is often confused with 903033 (multimeters with recording devices) or 903084 (other recording electrical instruments not specifically for V/C/R/P). The distinction lies in its focus on specific electrical parameters and the recording function, excluding general multimeters.
Top exporters and importers of HS code 903039, 2025
In 2025, the largest exporter of HS code 903039 in UN Comtrade data was Germany, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
