HS Code 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

HS code 9030.90 is the 6-digit subheading for 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. It is used for geiger counters, scintillation detectors, dosimeters, radiation survey meters and gamma spectrometers.

What HS 9030.90 covers

This HS code is unique as it covers two distinct areas: parts and accessories for the electrical measuring instruments of heading 9030, and instruments specifically for measuring or detecting various types of radiation (alpha, beta, gamma, x-ray, cosmic, and other radiations). Focusing on the latter, these radiation detection instruments are crucial for nuclear safety, medical diagnostics, scientific research, environmental monitoring, and industrial applications. Importers and exporters include research institutions, hospitals, nuclear facilities, and specialized manufacturers of safety and scientific equipment. Key aspects involve high sensitivity, accuracy, and robust design to ensure reliable detection and measurement of radiation levels, which is vital for protecting personnel, monitoring environmental impact, and advancing scientific understanding in fields like physics and chemistry.

Codes often confused with 9030.90

Common mistake. The 'parts and accessories' aspect can lead to confusion with parts for other electrical instruments. Radiation detection instruments might be confused with medical diagnostic equipment (e.g., 9022 for X-ray apparatus) if their primary function isn't just 'measuring or detecting radiation.'

Top exporters and importers of HS code 903090, 2025

In 2025, the largest exporter of HS code 903090 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.

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).
