What Changed
Effective January 1, 2026Under the 2024 Section 301 review, non-EV lithium-ion batteries (HTS 8507) from China were raised from 7.5% to 25%, effective January 1, 2026. Critical minerals (HTS 2601-2616) from China were raised from 0% to 25%, also effective January 1, 2026. Medical gloves and PPE (HTS 4015, 6307) were raised from 7.5% to 25%. These rates replace base list rates.
Rate Changes
| Item | Before | After |
|---|---|---|
| Lithium-ion batteries non-EV (HTS 8507) | 7.5% S301 | 25% S301 |
| Critical minerals (HTS 2601-2616) | 0% | 25% S301 |
| Medical gloves/PPE (HTS 4015, 6307) | 7.5% S301 | 25% S301 |
Who's Affected
Energy storage manufacturers, battery pack assemblers, and critical mineral supply chain companies. The critical minerals tariff affects cobalt, lithium, rare earths, and other strategic materials sourced from China. Companies that haven't diversified away from Chinese critical mineral sources face significant cost increases.
Analysis
Section 301 China Tariffs: Batteries and Critical Minerals Increases (effective 2026-01-01). Under the 2024 Section 301 review, non-EV lithium-ion batteries (HTS 8507) from China were raised from 7. Section 301 of the Trade Act of 1974 authorizes the USTR to investigate and respond to unfair trade practices by foreign governments, including subsidies and discriminatory policies that harm US commerce. The ongoing Section 301 action against China was initiated in 2018 and covers tens of billions of dollars in Chinese imports across four product lists. A four-year statutory review conducted in 2024 resulted in targeted increases on strategic sectors — electric vehicles, solar cells, batteries, semiconductors, and critical minerals — reflecting bipartisan consensus on the need to protect US competitiveness in clean energy and technology. Section 301 tariffs stack on top of the base MFN rate and, for certain products, on top of the Section 122 surcharge as well, creating compound tariff rates that can exceed 100% for some Chinese goods. The 2024 review confirmed that existing tariffs on Chinese goods will remain in force, providing businesses with certainty that Section 301 rates are not a temporary measure. USTR's approach of using "replacement rates" — where the 2024 increases replace the base list rates rather than stacking on top of them — is critical to understand when calculating effective tariff costs. For example, Chinese EVs face a 100% Section 301 rate that replaces the prior 25% rate; they do not face 125%.
Impact & Next Steps
Importers of Chinese goods should verify the specific List (1, 2, 3, or 4A) that applies to their HTS codes, as rates vary by list. The 2024 review replacement rates (EVs at 100%, solar at 50%) apply as final rates, not as additions to prior rates. Country-of-origin rules apply: products substantially transformed in China are subject to S301 even if shipped from a third country. Consider supply chain diversification for strategic categories to reduce S301 exposure.
