HS code for Chart recorder: 9030.84

Instruments and apparatus, n.e.c. in heading no. 9030, with a recording device.

Classification of chart recorder under HS 9030.84

HS code 9030.84 applies to instruments and apparatus for measuring or checking electrical quantities, provided they are equipped with a recording device. Heading 9030 is reserved for oscilloscopes, spectrum analyzers, and other instruments for measuring voltage, current, resistance, or power. The subheading 9030.84 is used for other instruments in this category that possess the capability to record the measured data, whether on paper charts or digital media. This classification is distinct from instruments that merely display a value without storing or plotting it. Under the Harmonized System, the inclusion of a recording mechanism is a primary feature for sub-classification. It is essential to distinguish these from instruments measuring non-electrical quantities. The classification follows the principle that the primary function of the device is the measurement of an electrical parameter, with the recording function being the secondary, defining characteristic for the subheading.

Codes often confused with 9030.84

Common mistake. The most frequent misclassification occurs with HS code 9025.80 (temperature recorders) or 9026.80 (pressure recorders). If the device records temperature, it must be in 9025, even if it uses electrical sensors. HS code 9030.84 is strictly for electrical quantities like Volts, Amps, or Ohms. Another error is using 9030.33, which is for instruments without a recording device. Additionally, if the device is a general-purpose computer used for recording, it would fall under 8471, but dedicated measuring instruments remain in Chapter 90.

Top exporters and importers of HS 903084 (the code used for chart recorder), 2025

In 2025, the largest exporter of HS 903084 (the code used for chart recorder) in UN Comtrade data was Israel, with 20% of world exports; the largest importer in UN Comtrade data was China, with 26% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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 chart recorder

What is the HS code for Chart recorder?

The HS code for Chart recorder is 903084 (Instruments and apparatus; n.e.c. in heading no. 9030, with a recording device). The HS code for a chart recorder that measures electrical quantities is 9030.84.

How do I classify Chart recorder for customs?

Chart recorder is classified under HS code 903084 — Instruments and apparatus; n.e.c. in heading no. 9030, with a recording device. This is a 6-digit subheading level code.

What if the recorder measures both temperature and voltage?

According to GRI 3(b), the classification depends on the essential character of the device. If it is marketed primarily as an electrical tester, 9030.84 applies; if as a weather/process monitor, 9025 might be more appropriate.

Which countries are the top exporters of chart recorder (HS 903084)?
