HS Code 8542.32 – Electronic integrated circuits; memories
HS code 8542.32 is the 6-digit subheading for electronic integrated circuits, memories. It is used for DRAM (Dynamic Random Access Memory), SRAM (Static Random Access Memory), NAND Flash memory, NOR Flash memory and EEPROM (Electrically Erasable Programmable Read-Only Memory).
What HS 8542.32 covers
This HS code is dedicated to memory integrated circuits, which are fundamental components for storing data in all digital electronic devices. This includes volatile memory like DRAM and SRAM, and non-volatile memory such as NAND flash, NOR flash, and EEPROM. The global trade in memory chips is enormous and highly cyclical, driven by demand from computing, mobile devices, data centers, and automotive industries. Major importers are countries with large-scale electronics assembly operations, including China, Vietnam, and various European nations, where these chips are integrated into smartphones, servers, PCs, and consumer electronics. The primary exporters are a concentrated group of nations with advanced semiconductor manufacturing capabilities, particularly South Korea, Taiwan, and the USA. Key factors in this trade include storage capacity, speed, power consumption, and packaging type. The market is characterized by significant capital investment in fabrication plants and continuous innovation in memory technology.

Codes often confused with 8542.32
Common mistake. Can be confused with processors (854231) if memory is integrated, or with discrete memory modules (847330 for computer parts), but 854232 is for the memory *chip itself*.
Top exporters and importers of HS code 854232, 2025
In 2025, the largest exporter of HS code 854232 in UN Comtrade data was South Korea, with 29% of world exports; the largest importer in UN Comtrade data was China, with 36% 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).
