Section 301 China Tariffs: Complete Product List & Rates

Section 301 of the Trade Act of 1974 authorizes the United States Trade Representative (USTR) to investigate and act against foreign trade practices that are "unreasonable or discriminatory" and burden US commerce. Unlike Section 232 (national security) or Section 122 (balance of payments), Section 301 is targeted at a specific country's trade behavior, not a broad economic condition. The current Section 301 tariffs on Chinese goods originated from a USTR investigation launched in August 2017, which found that China's practices regarding technology transfer, intellectual property, and innovation were unreasonable, discriminatory, and burden US commerce. The first tariffs took effect July 6, 2018. Subsequent lists were published in 2018, 2019, and 2020, gradually expanding coverage to virtually all Chinese imports. In 2024, the USTR completed the mandatory four-year statutory review of Section 301 tariffs and announced targeted rate increases for strategic sectors: electric vehicles to 100%, solar cells and modules to 50%, Chinese semiconductors to 50%, non-EV lithium-ion batteries to 25%, and Chinese critical minerals to 25%. These increases took effect at various dates from September 2024 through January 2026. Section 301 has no statutory sunset provision. It remains in effect until the USTR determines that the trade practices have been corrected, which in practice has not occurred. China's trade practices with respect to technology transfer and intellectual property have continued, and no administration has moved to terminate the S301 tariffs. They are best modeled as a permanent cost of sourcing from China.

Section 301 tariffs are organized into four lists, each targeting a different set of Chinese goods at a specific rate. Understanding which list your product falls under is the first step in calculating your China-specific tariff burden. List 1 — 25% rate, covering $34 billion in annual trade. Published July 6, 2018. Covers industrial machinery (HTS Chapter 84), aerospace components, robotics, motor vehicles, and medical devices. These were the initial goods targeted for their connection to China's "Made in China 2025" industrial policy — strategic sectors where the US alleged technology theft and unfair subsidization. List 2 — 25% rate, covering $16 billion in annual trade. Published August 23, 2018. Covers semiconductors (certain subheadings of 8541-8542), chemicals (Chapters 28-29), plastics (Chapter 39), electric motors (8501), motorcycles (8711), and others. This list targeted goods where China's unfair practices were specifically found in the USTR Section 301 investigation record. List 3 — 25% rate (raised from 10% on May 10, 2019), covering $200 billion in annual trade. The largest list by trade value. Covers most intermediate manufacturing goods, consumer electronics (partial coverage), furniture (Chapter 94), and a wide range of manufactured products. The original 10% rate was raised to 25% after trade negotiations broke down in May 2019. List 4A — 7.5% rate (reduced from 15% on February 14, 2020), covering $120 billion in annual trade. Consumer goods, apparel (Chapters 61-62), footwear (Chapter 64), electronics accessories, toys and games (Chapter 95), and household goods. The rate was reduced from 15% to 7.5% as part of the Phase One trade deal signed January 15, 2020.

The 2024 USTR statutory review resulted in targeted rate increases for specific strategic sectors. These increases are structured as replacement rates — they replace the base list rate, not stack on top of it. An EV from China is at 100% total S301 rate; it is not 25% (List 3) + 75% = 100%. The replacement structure prevents double-counting. Electric Vehicles (HTS 8703): 100% since September 27, 2024 (previous rate: 25% under List 3). This is the highest individual tariff rate in the US tariff schedule. It effectively prohibits price-competitive Chinese EVs from entering the US market, which was the stated policy objective given BYD and other Chinese manufacturers' cost advantage. Solar Cells and Modules (HTS 8541): 50% since September 27, 2024 (previous rate: 25% under List 3). This affects crystalline silicon solar cells and assembled modules — the primary inputs for US solar installation projects. Combined with S122 (15%), Chinese solar panels face 65% total tariff, plus MFN. Semiconductors (HTS 8541-8542): 50% since January 1, 2025 (previous rate: 25%). This rate increase on Chinese semiconductors, combined with export control restrictions, is part of the US strategy to prevent China from achieving advanced chip manufacturing capability. Lithium-Ion Batteries, Non-EV (HTS 8507): 25% since January 1, 2026 (previous rate: 7.5%). Covers batteries used in consumer electronics, power tools, and energy storage. Combined with existing S122 (15%) and MFN (~0%), Chinese batteries now face 40% total before MPF. Critical Minerals (HTS Chapters 2601-2616): 25% since January 1, 2026 (previous rate: 0%). Covers cobalt, lithium, rare earth elements, and other minerals where China has dominant global market share.

Section 301 is always additive. The stacking formula is: Total = MFN + max(S122, S232, Bilateral) + S301. Unlike S122 and S232, which are in a "max" relationship with each other (you pay the higher of the two, not both), Section 301 adds on top of whatever is in the middle tier. This makes Chinese goods the most expensive to import from among all countries, all else equal. Worked example: $10,000 shipment of Chinese furniture (List 3, 25% S301 rate). MFN for furniture (HTS Chapter 94): approximately 5%. S122: 15% (furniture is not S232-exempt, no bilateral deal for China). S301: 25%. Total tariff: 5% + 15% + 25% = 45%. Dollar amount: MFN $500 + S122 $1,500 + S301 $2,500 = $4,500. MPF: 0.3464% of $10,000 = $34.64. Total import cost: $4,534.64 on a $10,000 shipment. Worked example: $10,000 shipment of Chinese EVs (100% S301 rate). MFN for passenger vehicles: 2.5%. S122: 0% (passenger vehicles are S122-exempt, covered by S232 instead). S232 for autos: 25%. S301: 100% (replacing List 3 base of 25%). Total: 2.5% + 25% (S232, since it exceeds S122) + 100% = 127.5%. Dollar: $12,750 in duties on a $10,000 declared value. This makes Chinese EV imports commercially impossible. Worked example: $10,000 shipment of Chinese electronics accessories (List 4A, 7.5% S301 rate). MFN: ~3.4%. S122: 15%. S301: 7.5%. Total: 25.9%. Dollar: $2,590.

The four Section 301 lists together cover approximately $370 billion in Chinese goods — essentially all Chinese imports to the United States. In practice, imports from China have declined since the tariffs began but have not stopped. China remains the largest source of US goods imports despite the tariff burden. The economic impact has been partially absorbed by currency adjustments (the Chinese yuan depreciated against the dollar between 2018-2020), by suppliers absorbing some margin, and by US importers raising prices. Studies by the Federal Reserve and academic economists have found that US importers and consumers have borne the majority of the tariff cost, not Chinese exporters, contrary to the stated policy intent. For specific product categories, the impact varies enormously. Chinese apparel (List 4A at 7.5%) remains cost-competitive despite the tariff, because China's labor and manufacturing cost advantages are larger than 7.5%. Chinese EVs (100% S301) are completely excluded from the US market. Chinese solar panels (50% S301) have declined sharply in US market share, replaced by panels from Vietnam, Cambodia, and other Southeast Asian countries. The exclusion process allows specific companies to petition USTR for product-specific exclusions from Section 301 tariffs. Exclusions are granted on a case-by-case basis for goods that are not available from US or non-China sources, where the tariff causes severe economic harm to the petitioner. The exclusion process has had limited success overall — USTR has granted exclusions for niche industrial equipment and certain raw materials, but consumer product exclusions are rare.

As of March 2026, the USTR has announced new Section 301 investigations targeting additional Chinese trade practices. The March 2026 investigations focus on shipbuilding and maritime logistics (Chinese state subsidies for ship construction), agricultural biotechnology (Chinese investment in US farmland near military installations), and digital trade practices (Chinese data localization requirements that disadvantage US technology companies). These investigations could lead to new tariff lists or rate increases, but the timeline from investigation to tariff action is typically 12-18 months. Importers in the targeted sectors should monitor USTR docket filings, but no immediate rate changes are expected from these investigations before 2027. The more immediate March 2026 development is the ambiguity surrounding bilateral deals negotiated under IEEPA authority. China was not party to any bilateral deal — the administration's China policy was to maintain and increase S301 tariffs, not to negotiate them down. However, the IEEPA ruling has created broader legal uncertainty that China has cited in WTO dispute filings challenging the overall tariff regime. The WTO dispute panel process is slow (typically 3-5 years to final ruling) and the US has not complied with previous WTO adverse rulings on steel tariffs. For practical planning purposes, model Section 301 tariffs as permanent. A scenario where S301 rates are reduced would represent a major shift in US-China trade policy requiring either a comprehensive trade deal or a change in administration policy, neither of which is imminent.
