HS Code 8542.90 – Parts of electronic integrated circuits
HS code 8542.90 is the 6-digit subheading for parts of electronic integrated circuits. It is used for unmounted semiconductor dies (bare chips), IC lead frames, ceramic substrates for ICs, organic substrates for ICs and bonding wires for ICs.
What HS 8542.90 covers
This HS code covers the specialized parts and components used in the manufacturing and assembly of electronic integrated circuits (ICs). Unlike the finished ICs themselves, this category focuses on the intermediate materials and sub-components that are essential before an IC is fully encapsulated and functional. This includes items like unmounted semiconductor dies (chips before packaging), lead frames specifically for ICs, substrates, and certain packaging materials. Countries with significant semiconductor assembly, test, and packaging (ATP) operations, as well as advanced fabrication plants, are the primary importers, notably Taiwan, South Korea, China, and Singapore. Exporters are typically nations specializing in high-precision materials science, advanced chemical processing, and specialized manufacturing equipment, such as Japan, Germany, and the USA. The trade in these parts is highly technical, requiring stringent quality control and purity, as they directly impact the performance and reliability of the final integrated circuit.

Codes often confused with 8542.90
Common mistake. Often confused with parts for discrete semiconductor devices (854190) or even raw semiconductor wafers (which might fall under 381800 or 250610 if unprocessed), but 854290 is specific to parts *for* integrated circuits.
Top exporters and importers of HS code 854290, 2025
In 2025, the largest exporter of HS code 854290 in UN Comtrade data was Malaysia, with 33% of world exports; the largest importer in UN Comtrade data was Malaysia, with 35% 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).

What are common misclassifications for HS code 854290?
Often confused with parts for discrete semiconductor devices (854190) or even raw semiconductor wafers (which might fall under 381800 or 250610 if unprocessed), but 854290 is specific to parts *for* integrated circuits.
Which countries are the top exporters of goods under HS code 854290?
In 2025, the top exporters of HS code 854290 in UN Comtrade data were Malaysia ($12.0B, 33% of world exports), Taiwan (about $11.0B) and Hong Kong ($4.9B). World exports came to about $36.3B, 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.
