Section 232 tariff on semiconductors (certain advanced computing chips)

Advanced chip tariff (Section 232)

In effectSince Jan 15, 2026

What it is

Since Jan 15, 2026, a 25% tariff on top of the base rate applies to a narrow group of advanced computing chips from every country: logic integrated circuits, or articles containing one, that fall within set processing-performance and memory-bandwidth ranges and are classified in 8471.50, 8471.80 or 8473.30. Goods in those provisions that don't meet the technical parameters don't pay it (9903.79.02), and neither do qualifying chips imported for U.S. data centers, repairs or replacements, research and development, startups, consumer or civil industrial uses, or public sector uses. No drawback is available.

Legal authority: Section 232 of the Trade Expansion Act of 1962, as amended (19 U.S.C. 1862): Proclamation 11002 of Jan 14, 2026. Section 232 of the Trade Expansion Act of 1962 lets the President adjust imports of goods that the Commerce Department finds threaten to impair national security, including by adding duties.

It reaches 3 listed tariff codes or code groups (a listed heading or subheading covers every code under it).

"+" rates are added on top of the regular duty. Chapter 99 headings are the numbers filed on the entry along with the product's own code.

  • +25%Since Jan 15, 2026
    Only for goods that match: the imported products must be a logic integrated circuit, or an article that contains a logic integrated circuit, that meets the technical parameters of having: (1) a total processing performance greater than 14,000 and less than 17,500, and a total DRAM bandwidth greater than 4,500 GB/s and less than 5,000 GB/s; or (2) a total processing performance greater than 20,800 and less than 21,100, and total DRAM bandwidth greater than 5,800 GB/s and less than 6,200 GB/s

How it combines with other duties

Charged on top of the base rate and on top of any special (trade-agreement) rate. No other chapter 99 heading can lower it, and other chapter 99 duties are added on top (note 39(a)), except the Section 232 autos, trucks and metals duties and the IEEPA headings listed in note 39(a), which don't apply to these goods (Proclamation 11002, clause 5; CSMS 67400472), and three duties that exempt this heading: the forced-labor Section 301 tariff (note 52(f)(7)), Brazil's Section 301 duty under 9903.05.01 (note 50(a)(vi)(7)) and Canada's duty under 9903.03.13 (note 51(c)(7)). For chapter 98 goods under 9802.00.60 it's charged on the full value. Antidumping and countervailing duties still apply.
