Product classification
HS code for Operational amplifier: 8542.33
Electronic integrated circuits, amplifiers.
Classification of operational amplifier under HS 8542.33
Operational amplifiers, commonly known as op-amps, are classified under HS code 8542.33. This classification is determined by the product's nature as an electronic integrated circuit. Chapter 85 of the Harmonized System covers electrical machinery and equipment, while heading 8542 is dedicated specifically to electronic integrated circuits. Within this heading, subheading 8542.33 is reserved for amplifiers. The classification follows GRI 1, which prioritizes the terms of the headings and any relative section or chapter notes. Since an operational amplifier is a high-gain electronic voltage amplifier with a differential input, integrated onto a single semiconductor substrate (monolithic) or combined in a single package (hybrid/multi-chip), it meets the technical definition of an integrated circuit amplifier. This code is used regardless of the op-amp's specific application, whether it is used in consumer electronics, industrial control systems, or telecommunications, as long as it remains a discrete integrated component.

Codes often confused with 8542.33
Common mistake. Operational amplifiers are often misclassified under HS code 8518.40, which covers audio-frequency electric amplifiers. However, 8518.40 is intended for finished amplifier units or boards that perform a complete function, whereas 8542.33 is for the component-level integrated circuit. Another common error is using HS code 8543.70 for other electrical machines and apparatus. This is incorrect because heading 8542 is more specific for integrated circuits. Additionally, discrete transistor-based amplifiers should be classified under 8541, not 8542, as they are not integrated circuits.
Top exporters and importers of HS 854233 (the code used for operational amplifier), 2025
In 2025, the largest exporter of HS 854233 (the code used for operational amplifier) in UN Comtrade data was Malaysia, with 27% of world exports; the largest importer in UN Comtrade data was China, with 40% 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 854233, not only operational amplifier.

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).
