From MFG Calcs data: Semiconductors and integrated circuits

U.S. imports of semiconductors and integrated circuits (headings 8541, 8542) came to $52.46B in 2025, with $1.69B in calculated duty: an effective duty of 3.2%, every duty included.

Effective duty in Sep 2026: 1.2%, against 4.1% in Sep 2025.

Largest sources in 2025: Taiwan $12.58B at 0.2% effective duty; Malaysia $11.13B at 1.0% effective duty; Israel $4.48B at 0.0% effective duty; Indonesia $3.08B at 11.3% effective duty; South Korea $2.42B at 2.7% effective duty.

These are family totals from U.S. import statistics published through USITC DataWeb, not this heading's rate alone; effective duty is calculated duty as a share of customs value, an estimate, not a ruling.

About these rates

The rates are those printed in the 2026 HTS Revision 23, published by the U.S. International Trade Commission. A 10-digit statistical line takes the rates printed on the 8-digit line above it. Chapter 99 duties (Section 232, Section 301, IEEPA) depend on the product, the origin and the date, are charged on top, and are not included. A code here is a strong lead, not a ruling: confirm it with a customs broker or a CBP binding ruling.
