Product classification
HS code for Ammeter: 9030.33
Instruments and apparatus, for measuring or checking voltage, current, resistance or power, without a recording device (excluding multimeters).
Classification of ammeter under HS 9030.33
An ammeter is classified under HS code 9030.33. This code is designated for instruments and apparatus for measuring or checking voltage, current, resistance, or power, without a recording device, and specifically excluding multimeters. As an instrument designed solely to measure electrical current in amperes, the ammeter fits the criteria for this subheading perfectly. This classification falls under Chapter 90, which encompasses optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. The classification logic follows the principle that specialized instruments are categorized based on their primary function and the absence of additional features like data logging or multi-parameter measurement. If an ammeter were to include a mechanism for recording measurements over time, it would be reclassified under 9030.32. Furthermore, if the device were integrated into a multimeter capable of measuring multiple electrical properties, it would fall under 9030.31. Ammeters are essential in various sectors, including automotive diagnostics, industrial power management, and laboratory research, and their classification remains consistent regardless of whether they use analog or digital display technology.

Codes often confused with 9030.33
Common mistake. Ammeters are often misclassified under HS code 9030.31, which is specifically for multimeters. They are also confused with HS code 9030.32, which is for instruments that include a recording device. Additionally, some importers mistakenly use 9030.39, which is a residual category for other instruments not elsewhere specified, but since ammeters measure current without recording, 9030.33 is the more specific and correct code.
Top exporters and importers of HS 903033 (the code used for ammeter), 2025
In 2025, the largest exporter of HS 903033 (the code used for ammeter) 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.
Figures cover everything classified under HS 903033, not only ammeter.

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).
