U.S. imports of memory integrated circuits (HS 854232) totaled $747.3M in July 2026, traded with 54 countries.
Importers of Memory Integrated Circuits paid $4.7M in duties in July 2026 — an effective duty rate of 48% on $9.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Memory Integrated Circuits imports of $747.3M in July 2026 ran 30% above the year-to-date monthly average of $573.4M.
Last updated: July 2026 dataDRAM, SRAM, EEPROM, EPROM, and other memory ICs are classified here, with the US tariff schedule subdividing DRAM by capacity thresholds ranging from 128 MB and below up to over 1 GB — distinctions that reflect successive generations of memory technology. Taiwan and South Korea are the dominant suppliers, with the latter home to the world's largest DRAM and NAND flash producers; Japan and Malaysia round out the top sources. Antidumping and countervailing duty orders have historically targeted certain memory products, so importers should verify whether any active orders cover the specific memory type and origin before entry. The breadth of lines under this heading means that capacity specifications on commercial invoices must be precise to avoid misclassification.

CBP requires the memory capacity per chip (in MB or GB) to assign the correct 10-digit line. Commercial invoices should state the capacity, memory type (DRAM, SRAM, etc.), and part number for each SKU. Mixed-capacity shipments must be entered on separate lines corresponding to each capacity band. Manufacturer datasheets or product specifications should be retained as supporting documentation.
Yes, antidumping duty orders have been imposed on certain DRAM and other memory products in past trade cases. Importers should search the USITC and Commerce Department's antidumping/countervailing duty order database by HTS code and country of origin before each shipment, as orders can be revoked, modified, or reinstated through sunset reviews. Working with a licensed customs broker familiar with semiconductor trade remedies is advisable for high-volume memory imports.
