Product classification
HS code for Voltage recorder: 9030.39
Instruments and apparatus, for measuring or checking voltage, current, resistance or power, with a recording device (excluding multimeters).
Classification of voltage recorder under HS 9030.39
The HS code 9030.39 applies to instruments and apparatus for measuring or checking voltage, current, resistance, or power, provided they are equipped with a recording device. This classification falls under Chapter 90, which covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments. The inclusion of a "recording device" is the critical differentiator for this subheading. While standard multimeters or voltmeters that only provide a real-time display are classified elsewhere, any device that can log, store, or print voltage data over time is directed to 9030.39. This includes both analog chart recorders and modern digital data loggers designed for electrical parameter monitoring. The classification ensures that sophisticated diagnostic equipment is separated from basic handheld measurement tools.

Codes often confused with 9030.39
Common mistake. Voltage recorders are frequently misclassified under 9030.31, which is specifically for multimeters without a recording function. They may also be confused with 9030.33, which covers other instruments for measuring voltage without a recording device. Another error is using 8543, which is a general category for electrical machines and apparatus with individual functions, but Chapter 90 is more specific for measuring and recording instruments. Finally, if the device is purely an oscilloscope, it should be under 9030.20.
Top exporters and importers of HS 903039 (the code used for voltage recorder), 2025
In 2025, the largest exporter of HS 903039 (the code used for voltage recorder) 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.
Figures cover everything classified under HS 903039, not only voltage recorder.

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).

Questions about voltage recorder
What is the HS code for Voltage recorder?
The HS code for Voltage recorder is 903039 (Instruments and apparatus; for measuring or checking voltage, current, resistance or power, with a recording device (excluding multimeters)). The HS code for instruments measuring voltage with a recording device is 9030.39.
How do I classify Voltage recorder for customs?
Voltage recorder is classified under HS code 903039 — Instruments and apparatus; for measuring or checking voltage, current, resistance or power, with a recording device (excluding multimeters). This is a 6-digit subheading level code.
How does a voltage recorder differ from a multimeter in HS codes?
A multimeter is typically 9030.31, while a voltage recorder must have a data logging or recording function to be classified under 9030.39.
Which countries are the top exporters of voltage recorder (HS 903039)?
In 2025, the top exporters of HS 903039 (the code used for voltage recorder) in UN Comtrade data were Germany ($399M, 18% of world exports), China ($369M) and the United States ($261M). World exports came to about $2.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
