Section 301 China tariff increases from the 2024 four-year review

2024 China tariff increases (Section 301)

In effectSince Sep 27, 2024

What it is

After its four-year review of the 2018 China tariffs, and at the President's direction, USTR raised or added Section 301 tariffs on products of China in strategic sectors, in stages. From Sep 27, 2024: 25% on steel and aluminum products, critical minerals, lead-acid battery parts, lithium-ion batteries for electric vehicles, respirators, non-disposable face masks and ship-to-shore cranes; 50% on solar cells; 100% on electric vehicles and on syringes and needles. From Jan 1, 2025: 50% on semiconductors, polysilicon and wafers, and 25% on tungsten products; during 2025 only, 50% on medical gloves and 25% on disposable face masks. From Jan 1, 2026: 25% on natural graphite, permanent magnets and all lithium-ion batteries, 50% on respirators and face masks, and 100% on medical gloves. Enteral syringes were exempt until the end of 2025, and ship-to-shore cranes under contracts dated before May 14, 2024 were exempt if entered before May 14, 2026; other cranes of the same subheading pay nothing extra. These rates replaced the 2018-19 list rates on the same products rather than adding to them. USTR has said the semiconductor rate will rise on Jun 23, 2027, by an amount it will announce at least 30 days before.

Legal authority: Section 301 of the Trade Act of 1974, as amended; modification under section 307 by the U.S. Trade Representative, at the direction of the President (memorandum of May 14, 2024). Section 301 of the Trade Act of 1974 lets the U.S. Trade Representative act against foreign acts, policies and practices that are unreasonable or discriminatory and burden U.S. commerce, including by adding duties on imports.

It reaches 394 listed tariff codes or code groups (a listed heading or subheading covers every code under it).

How it combines with other duties

Charged on top of the base rate: covered products of China “shall also be subject to the general rates of duty” (note 31(a)), and goods eligible for trade-agreement rates (general note 3(c)(i)) or for subchapter II duty exemptions still pay it. It doesn't apply to goods properly entered under chapter 98, except under 9802.00.40, .50, .60 and 9802.00.80: for the first three it applies to “the value of repairs, alterations, or processing performed abroad”, and for 9802.00.80 to “the value of the article less the cost or value of such products of the United States” (note 31(a)). Covered goods remain subject to “antidumping, countervailing, or other duties, fees, exactions and charges that apply to such products”. It is not added to the 2018-19 List 1 to 4A duties (note 20): USTR took each product off the note 20 lists when its note 31 rate began (89 FR 76581, Annex C items 9 to 20, for example “note 20(b) to subchapter III of chapter 99 is modified by deleting the following 8-digit subheading numbers”, p. 76607; 89 FR 101682, Annex B item 2), and in Revision 20 none of the note 31 subheadings is on a note 20 list (the respirator and face-mask statistical numbers are named as exceptions in note 20(s)(ii)).
