HS code for Ohmmeter: 9030.33

Instruments and apparatus, for measuring or checking voltage, current, resistance or power, without a recording device (excluding multimeters).

Classification of ohmmeter under HS 9030.33

An ohmmeter is classified under HS code 9030.33, which pertains to instruments and apparatus for measuring or checking electrical quantities. Chapter 90 of the Harmonized System covers optical, photographic, cinematographic, measuring, checking, precision, medical, or surgical instruments. Within this chapter, heading 9030 is dedicated to oscilloscopes, spectrum analyzers, and other instruments for measuring or checking electrical quantities. Subheading 9030.33 specifically identifies instruments for measuring voltage, current, resistance, or power that do not have a recording device and are not multimeters. The classification is driven by the device's specific function—measuring electrical resistance—and the absence of integrated features like data recording or multi-functionality. If the device were capable of measuring multiple parameters like voltage and current simultaneously, it would be classified as a multimeter. The technical distinction between a recording and non-recording device is also critical; a recording device would include internal memory or a paper chart output to track measurements over time.

Codes often confused with 9030.33

Common mistake. The most frequent misclassification occurs with HS code 9030.31, which is reserved for multimeters. A multimeter can measure resistance, but because it also measures voltage and current, it is more specific than an ohmmeter. Another common error is using HS code 9030.39, which is for instruments that include a recording device. If the ohmmeter has a built-in data logger, it must be moved to 9030.39.

Top exporters and importers of HS 903033 (the code used for ohmmeter), 2025

In 2025, the largest exporter of HS 903033 (the code used for ohmmeter) in UN Comtrade data was Germany, with 17% of world exports; the largest importer in UN Comtrade data was the United States, with 17% 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).

Questions about ohmmeter

What is the HS code for Ohmmeter?

The HS code for Ohmmeter is 903033 (Instruments and apparatus; for measuring or checking voltage, current, resistance or power, without a recording device (excluding multimeters)). The standard HS code for a dedicated ohmmeter without a recording device is 9030.33.

How do I classify Ohmmeter for customs?

Ohmmeter is classified under HS code 903033 — Instruments and apparatus; for measuring or checking voltage, current, resistance or power, without a recording device (excluding multimeters). This is a 6-digit subheading level code.

Does this code include multimeters that measure resistance?

No, multimeters are classified under HS code 9030.31 because they are multi-functional instruments capable of measuring more than just resistance.

Which countries are the top exporters of ohmmeter (HS 903033)?

In 2025, the top exporters of HS 903033 (the code used for ohmmeter) in UN Comtrade data were Germany ($526M, 17% of world exports), China ($498M) and the United States ($452M). World exports came to about $3.2B, 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.

Which countries are the top importers of ohmmeter (HS 903033)?
