U.S. imports of semiconductors (End-Use 21320) totaled $10.2B in April 2026, traded with 109 countries.
Importers of Semiconductors paid $125.9M in duties in April 2026 — an effective duty rate of 13% on $944.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Semiconductors imports of $10.2B in April 2026 ran 15% above the year-to-date monthly average of $8.9B.
Last updated: April 2026 dataImported semiconductors — including memory, logic, analog, and discrete devices — are foundational inputs for US electronics manufacturing, defense supply chains, and consumer technology. Taiwan is the dominant supplier of advanced logic chips, reflecting the concentration of leading-edge foundry capacity there, while South Korea is a primary source for memory devices. Supply chain resilience has become a central concern for importers given geopolitical risk concentration, and the CHIPS and Science Act has introduced domestic incentive programs that may influence long-term sourcing strategies.

Some semiconductor subheadings are subject to Section 301 tariffs when the country of origin is China, while others may be excluded or subject to modified rates. The applicability depends on the specific 10-digit HTS classification and the current status of any product exclusions. Importers should verify the Section 301 list status for each subheading and monitor USTR notices for exclusion updates.
CBP generally treats the country where the wafer fabrication (diffusion) occurs as the country of origin for semiconductor devices, as this is considered the substantial transformation step. Subsequent assembly, testing, and packaging in a different country typically do not change the origin. However, the analysis can be fact-specific, and importers with complex multi-country supply chains should consider seeking a CBP binding ruling to confirm origin before entry.
