Semiconductors and Integrated Circuits: Statutory & Effective Tariff Rates

Statutory HTS duty rates for 20 semiconductors and integrated circuits tariff lines (MFN Free), from USITC. Effective rate May 2026: 1.79%; monthly history since 202

The short answer

  • The effective U.S. tariff on semiconductors and integrated circuits was 1.79% in May 2026, down from 4.12% a year earlier — calculated duties actually paid divided by customs value, from USITC data. The statutory MFN rate is Free across 20 HTS lines in the 2026 schedule. Taiwan is the largest source, holding 24% of 2025 imports.

Statutory rates from the schedule

  • Diodes, transistors, power devices, LEDs, and integrated circuits — the silicon inside every control and drive. This family covers HTS headings 8541, 8542: 20 eight-digit rate lines with MFN (column 1, general) rates of Free in the 2026 schedule.
  • Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.91.05) that apply on top of the MFN column.

What importers actually paid

  • Latest month on record (2026-05): 1.79% effective on $4.9B of imports, versus 4.12% in the same month a year earlier. The monthly archive holds 41 observations from 2023-01 through 2026-05.
  • In 2025, U.S. imports for consumption in this family totaled $52.5B in customs value and paid $1.7B in calculated duties: an effective tariff rate of 3.22%. The effective rate captures Section 301/232 overlays, exclusions, and special-program use that the statutory column cannot.
  • A year earlier the effective rate was 1.12%, so the duty burden rose 2.1 points.
  • Top source countries in 2025: Taiwan ($12.6B at 0.2%), Malaysia ($11.1B at 0.98%), Israel ($4.5B at 0.01%), Indonesia ($3.1B at 11.35%), South Korea ($2.4B at 2.67%).
  • For scale, 2025 imports in this family equal 12.1% of the U.S. computer and electronic products industry's $434B gross output (2025, BEA).

Frequently asked questions

  • What is the U.S. tariff rate on semiconductors and integrated circuits? Importers paid an effective rate of 1.79% in May 2026 (calculated duties ÷ customs value, USITC DataWeb). The statutory MFN rate is Free; Section 301/232 overlays and special programs explain the difference.
  • What is the statutory MFN duty rate for semiconductors and integrated circuits? Free across the family's 20 eight-digit HTS lines in the 2026 Harmonized Tariff Schedule (headings 8541, 8542).
  • Which countries supply the most semiconductors and integrated circuits to the U.S.? Top sources in 2025: Taiwan ($12.6B at 0.2%), Malaysia ($11.1B at 0.98%), Israel ($4.5B at 0.01%). Sourcing is diversified: Taiwan holds 24% of imports.
  • How much semiconductors and integrated circuits does the U.S. import? $52.5B of customs value in 2025, paying $1.7B in calculated duties — an effective tariff of 3.22%.
  • Is the U.S. a net importer of semiconductors and integrated circuits? Yes — a net importer in 2025: $52.5B imported vs $31.0B exported (exports are 59% of imports).
