HS Code 8542.33 – Electronic integrated circuits; amplifiers
HS code 8542.33 is the 6-digit subheading for electronic integrated circuits, amplifiers. It is used for operational amplifiers (Op-amps), audio power amplifiers, low-noise amplifiers (LNAs), RF amplifiers and instrumentation amplifiers.
What HS 8542.33 covers
This category covers integrated circuits specifically designed to amplify electrical signals, making them stronger or increasing their power. These ICs are vital in a wide range of applications, from audio systems and radio frequency (RF) communications to sensor interfaces and industrial control. They can be operational amplifiers (op-amps), power amplifiers, low-noise amplifiers (LNAs), or audio amplifiers. Countries with significant electronics manufacturing bases, particularly for consumer audio, telecommunications equipment, and industrial electronics, are the main importers, including China, Mexico, and various EU members. Exporters are typically nations with strong analog and mixed-signal semiconductor design and fabrication expertise, such as the USA, Germany, Japan, and Taiwan. Key considerations in this trade include gain, bandwidth, power efficiency, noise performance, and linearity. The demand is driven by the proliferation of wireless devices, high-fidelity audio equipment, and precision instrumentation.

Codes often confused with 8542.33
Common mistake. Sometimes confused with discrete transistors (854121) used for amplification or other general-purpose analog ICs (854239), but 854233 is specifically for *integrated circuit* amplifiers.
Top exporters and importers of HS code 854233, 2025
In 2025, the largest exporter of HS code 854233 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.

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).
