Product classification
HS code for Oscilloscope probes: 9030.90
Instruments, apparatus for measuring, checking electrical quantities, not meters of heading no. 9028, parts and accessories, for measuring or detecting alpha, beta, gamma, x-ray, cosmic and other radiations.
Classification of oscilloscope probes under HS 9030.90
Oscilloscope probes are classified under HS code 9030.90. This classification is determined by the status of the probes as essential accessories for instruments used to measure or check electrical quantities. Heading 9030 covers a wide range of electrical measuring tools, including oscilloscopes (9030.20). According to Note 2(b) to Chapter 90, parts and accessories that are suitable for use solely or principally with a particular kind of machine, instrument, or apparatus are to be classified with those machines or instruments. Since oscilloscope probes are specifically designed to interface with oscilloscopes to facilitate signal measurement, they are classified under the "parts and accessories" subheading of the same heading as the oscilloscope itself. This subheading, 9030.90, encompasses parts for all instruments within heading 9030, provided they are not more specifically described elsewhere in the nomenclature. These probes are sophisticated devices that may include active circuitry to ensure high-impedance input and signal fidelity, but their identity remains as an accessory to the primary measuring instrument.

Codes often confused with 9030.90
Common mistake. Oscilloscope probes are often misclassified as simple insulated wire or cables under HS code 8544.42. While they do contain wire, their specialized function as a measurement interface makes them accessories of heading 9030. They are also sometimes confused with the main instrument code 9030.20, but as separate components, they must be classified under the parts and accessories code 9030.90.
Top exporters and importers of HS 903090 (the code used for oscilloscope probes), 2025
In 2025, the largest exporter of HS 903090 (the code used for oscilloscope probes) in UN Comtrade data was Malaysia, with 21% of world exports; the largest importer in UN Comtrade data was Taiwan, with about 16% 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 903090, not only oscilloscope probes.

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 oscilloscope probes
What is the HS code for Oscilloscope probes?
The HS code for Oscilloscope probes is 903090 (Instruments, apparatus for measuring, checking electrical quantities, not meters of heading no. 9028; parts and accessories, for measuring or detecting alpha, beta, gamma, x-ray, cosmic and other radiations). The HS code for Oscilloscope probes is 9030.90.
How do I classify Oscilloscope probes for customs?
Oscilloscope probes is classified under HS code 903090 — Instruments, apparatus for measuring, checking electrical quantities, not meters of heading no. 9028; parts and accessories, for measuring or detecting alpha, beta, gamma, x-ray, cosmic and other radiations. This is a 6-digit subheading level code.
Can a probe be classified under 8544 if it is just a cable?
Generally, no. If the cable is specifically designed and marketed as an oscilloscope probe with the necessary connectors and impedance matching, it is classified as an accessory under 9030.90.
Which countries are the top exporters of oscilloscope probes (HS 903090)?
In 2025, the top exporters of HS 903090 (the code used for oscilloscope probes) in UN Comtrade data were Malaysia ($2.5B, 21% of world exports), Japan ($1.9B) and the United States ($1.5B). World exports came to about $11.8B, 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 oscilloscope probes (HS 903090)?
In 2025, the top importers of HS 903090 (the code used for oscilloscope probes) in UN Comtrade data were Taiwan (about $1.8B, 16% of world imports), the United States ($1.2B) and South Korea ($1.2B). World imports came to about $11.1B, 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.
Is the HS code for Oscilloscope probes the same in all countries?
The base HS code 903090 for Oscilloscope probes is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for oscilloscope probes in Brazil?
Brazil splits HS 903090 into 2 NCM codes, so the right one for oscilloscope probes depends on the product's details: 9030.90.10 (Parts and accessories, ionising radiation meters), 9030.90.90 (Parts and accessories, electrical test instruments).
