Section 301 Tariffs Explained: 2026 List & Current Status

What began as a targeted measure to protect American intellectual property has rapidly transformed into the structural cornerstone of modern U.S. trade policy. For supply chain managers and global importers, navigating the landscape of Section 301 tariffs is no longer just a compliance exercise—it is a critical factor in financial survival. With recent legal rulings cementing legacy duties and new enforcement mechanisms expanding to dozens of global economies, understanding these surcharges is essential for accurate cost forecasting. This guide breaks down how the current tariff lists operate, who bears the economic burden, and what businesses can expect from future regulatory changes.

What Are Section 301 Tariffs and Why Do They Still Matter in 2026?

Section 301 of the Trade Act of 1974 grants the Office of the U.S. Trade Representative (USTR) the authority to investigate and impose sanctions—typically tariffs—on foreign countries whose trade practices unfairly burden or restrict U.S. commerce. Originally utilized to penalize intellectual property theft and forced technology transfers, Section 301 has become the structural foundation of U.S. trade policy in 2026. Following the Supreme Court's February 2026 ruling that struck down blanket tariffs under the International Emergency Economic Powers Act (IEEPA), the executive branch pivoted to Section 301 to legally reconstruct its global tariff wall.

The application of Section 301 tariffs has expanded dramatically over the past year, shifting from a China-specific deterrent to a multinational enforcement mechanism. The most significant 2026 developments include:

• The 60-Economy Forced Labor Probe: In June 2026, USTR Ambassador Jamieson Greer proposed a 12.5% ad valorem tariff on up to 60 economies that fail to adequately prohibit the importation of goods produced with forced labor. This single action is designed to effectively replace IEEPA-era policies and is projected to target approximately $166 billion in imports.
• Supreme Court Validation of China Tariffs: On June 15, 2026, the U.S. Supreme Court declined to review HMTX Industries LLC v. United States. This denial exhausted the primary legal challenge to the original Section 301 tariffs on Chinese goods, cementing those duties and forcing importers to rely strictly on the USTR's Section 301 exclusions list for relief.
• Targeted Sector Investigations: The USTR has initiated new, highly specific investigations, such as the June 2026 probe into Germany’s pharmaceutical pricing models and ongoing reviews of Brazilian trade practices.

Importers often confuse Section 301 duties with other prominent trade actions. The precise boundary between them lies in the statutory trigger and the investigating agency.

Section 301 vs. Section 232 Tariffs

The expansion of Section 301 carries distinct trade-offs for domestic supply chains. While these tariffs generate substantial federal revenue and provide unilateral leverage in bilateral negotiations, they require rigorous administrative processes—including Federal Register notices, public comment periods, and formal hearings—before implementation. Companies relying on foreign inputs must continuously monitor the USTR's Section 301 tariff lookup tools, as the list of affected products and temporary exclusions fluctuates heavily based on these ongoing administrative reviews.

Which Goods Are Currently Covered by the Section 301 Tariff List?

As of mid-2026, the Section 301 tariff list covers thousands of Chinese industrial and consumer products, alongside a newly proposed expansion targeting goods from 60 additional economies over forced labor enforcement failures. The scope encompasses two distinct enforcement actions.

First, the legacy Section 301 tariffs on China (Lists 1 through 4A) penalize technology transfer and intellectual property practices. This inventory heavily weights semiconductors, clean energy equipment (including solar cells and electric vehicle batteries), medical supplies, industrial machinery, and raw metals. Second, the June 2026 forced labor investigations expand Section 301 coverage globally. If formalized, this secondary list will capture textiles, apparel, agricultural imports, and manufactured goods from economies lacking explicit bans on goods produced wholly or partly with forced labor.

What Rate Does Each Product Category Face Right Now?

Current Section 301 tariffs range from 7.5% on legacy consumer goods to a prohibitive 100% on specific high-tech imports. The Office of the United States Trade Representative (USTR) applies these ad valorem duties on top of standard Most-Favored-Nation (MFN) rates.

To have these Section 301 tariffs explained in the context of other trade actions, buyers must differentiate between overlapping statutes. While Section 232 and 301 tariffs both currently target metals like steel and aluminum, they rely on different legal frameworks. Section 232 addresses national security threats, whereas Section 301 retaliates against unfair trade practices. Chinese steel imports routinely face both duties concurrently.

Have Any Items Been Removed or Exempted Since the Original Lists?

Yes, but the window for relief has narrowed significantly as the USTR shifts from granting temporary relief to enforcing permanent supply chain decoupling. An exemption permanently carves a Harmonized Tariff Schedule (HTS) code out of the target list, while an exclusion provides temporary duty relief for specific product categories that importers cannot source elsewhere.

Importers historically submitted petitions to secure relief if a product was unavailable outside the target country. However, the current landscape strictly limits this mechanism:

• Mass Expirations (2024): The USTR allowed the vast majority of the original 352 general exclusions and 77 COVID-related exclusions to expire in mid-2024. Importers who failed to demonstrate active, quantifiable efforts to move sourcing out of China lost duty-free access.
• Current Extended Exclusions: As of 2026, the active Section 301 exclusions list is limited primarily to 164 critical machinery items and 14 specific solar manufacturing equipment categories. These extensions were granted exclusively where alternative global capacity remains functionally non-existent.
• Future Exclusion Windows: With the June 2026 proposal targeting 60 new economies, the USTR will establish a separate public comment and exclusion docket.

Because the regulatory status of specific goods changes frequently through USTR notices, manual tracking is risky. Supply chain managers must use the official USTR Section 301 tariff lookup tool or download the latest Section 301 tariff list PDF directly from the Federal Register to verify if their specific 8-digit HTS subheadings still qualify for relief.

How Did Section 301 Tariffs Get to Where They Are Today?

Understanding which items are currently penalized requires looking at how these duties have evolved. Section 301 tariffs originated in 2018 as a targeted penalty on $370 billion of Chinese imports but evolved by mid-2026 into a near-universal 10% to 12.5% levy on 60 major economies. The shift transformed the statute from a narrowly applied intellectual property enforcement mechanism into a broad tool for global trade restructuring.

How Did the Original 2018–2019 Lists Expand Over Time?

The initial Section 301 action against China escalated through four distinct tranches between July 2018 and February 2020, ultimately capturing approximately $370 billion in import value. The Office of the U.S. Trade Representative (USTR) structured these penalties to systematically pressure Beijing over forced technology transfers and intellectual property theft.

• List 1 (July 2018): Imposed a 25% tariff on $34 billion of Chinese industrial and technological goods.
• List 2 (August 2018): Added $16 billion in additional industrial imports at 25%.
• List 3 (May 2019): Captured $200 billion in consumer and intermediate goods, eventually raised to 25%.
• List 4A (February 2020): Applied a 7.5% tariff on $120 billion in remaining consumer goods, while List 4B was indefinitely suspended following the Phase One Trade Agreement.

Importers absorbed an estimated 20.7% effective tariff rate, driving supply chain reconfiguration to countries like Mexico and Vietnam. While the tariffs successfully generated roughly $80 billion annually in U.S. customs revenue by 2024, the primary trade-off fell on domestic manufacturers who faced higher input costs for intermediate goods.

What Did the 2024 Biden-Era Review Change?

The statutory four-year review concluded in May 2024 by maintaining the existing baseline tariffs while aggressively spiking rates on $18 billion of strategic Chinese imports to counter state-subsidized overcapacity. Rather than unwinding the 2018 lists, the Biden administration embedded them as permanent structural barriers targeting critical minerals, green energy supply chains, and legacy semiconductor manufacturing.

A parallel executive action tightened de minimis exemptions, closing a loophole that previously allowed sub-$800 shipments to bypass these duties. This phase confirmed a bipartisan consensus: Section 301 tariffs on China were no longer temporary negotiating leverage, but long-term industrial policy designed to insulate domestic producers from artificially cheap foreign competition.

What Has the Trump Administration Done to Section 301 Rates in 2025–2026?

Following the Supreme Court's invalidation of his initial IEEPA tariffs, President Trump leveraged Section 301 in early 2026 to propose near-universal levies of 10% to 12.5% on 60 economies. This unprecedented expansion targets nations accounting for 99.4% of all U.S. imports.

In March 2026, the USTR launched investigations into these trading partners based on systemic failures to enforce forced labor prohibitions. By June 2, 2026, the USTR issued affirmative findings across all 60 economies, proposing a two-tiered tariff system where most nations face a 12.5% levy, with select partners like Indonesia receiving 10% due to reciprocal trade commitments. Certain targeted actions run concurrently, including a proposed 25% levy on imports from Brazil.

The policy marks a definitive break from historical application. The statute is no longer exclusively a country-specific punitive measure, but a primary mechanism for systemic tariff collection. As the July 24, 2026 expiration for temporary Section 122 tariffs approaches, major corporations like Ford Motor Co. and Nestlé have aggressively petitioned the USTR for relief. These firms are actively lobbying to expand the Section 301 exclusions list, citing a lack of domestic manufacturing capacity to substitute the heavily taxed foreign supply.

Who Actually Pays Section 301 Tariffs and How Much Does It Cost?

Regardless of whether a company is a multinational giant or a mid-sized buyer, the financial mechanics remain the same. United States importers pay Section 301 tariffs directly to U.S. Customs and Border Protection (CBP). While the political intent of the statute is to penalize foreign trade practices, the economic burden falls almost entirely on domestic firms and end consumers through immediate margin compression and subsequent price inflation.

Do U.S. Importers or Chinese Exporters Bear the Cost?

U.S. importers of record bear the direct financial burden, paying the duties to CBP at the port of entry before goods can clear customs. The foreign exporter does not write a check to the U.S. government. To calculate the precise landed costs, supply chain managers utilize a Section 301 tariff lookup tool to cross-reference their specific Harmonized Tariff Schedule (HTS) codes against active USTR schedules.

Economic consensus from the National Bureau of Economic Research (NBER) and the U.S. International Trade Commission (USITC) shows a near 100% pass-through rate. Exporters have historically maintained their free-on-board (FOB) prices rather than discounting them to offset the tariff impact. As a result, the U.S. buyer absorbs the full surcharge of Section 301 tariffs on China.

Faced with these added costs, domestic firms must choose between absorbing the hit to their profit margins or raising retail prices. This dynamic is rapidly expanding. While originally confined to China, the USTR’s June 2026 forced-labor investigations push this identical payment mechanism onto imports from 60 economies. Companies seeking relief from these specific duties must petition through the formal Section 301 exclusions list, though approvals outside of medical supplies or highly scarce industrial inputs remain exceptionally rare.

Which Industries Are Paying the Highest Effective Rates?

The automotive, semiconductor, and clean energy sectors face the highest peak rates under China-specific actions, while the apparel and broad manufacturing sectors face the widest exposure under the 2026 global forced-labor tariffs.

The legacy framework targeting China relies on hyper-targeted, punitive rates to reshape industrial supply chains. Rates on Chinese EVs sit at 100%, effectively closing the U.S. market, while 50% levies on legacy semiconductors force a direct restructuring of hardware sourcing. Importers often face compounding financial penalties when these levies stack with other protective measures, such as combined Section 232 and 301 tariffs applied to targeted steel and aluminum imports.

The mid-2026 USTR actions fundamentally alter the cost structure for global consumer goods. By proposing blanket 10% to 12.5% tariffs on 60 economies—deployed largely to replace the judicially struck-down IEEPA measures—the USTR exposes the global apparel and textile industries to steep new baseline costs. To manage this specific sector risk, the USTR engineered a specialized textile mechanism that allows certain import volumes to enter at reduced rates, strictly on the condition that the trading partner purchases matching volumes of U.S. cotton.

Are Section 301 Tariff Rates or Exemptions Expected to Change Soon?

Yes—sweeping expansions are currently underway in 2026 that shift Section 301 tariffs from a China-specific tool to a global enforcement mechanism. At the same time, legacy rates on Chinese goods are now legally permanent, and the baseline for new exemptions is narrowing.

The 2026 Global Expansion: Tariffs on 60 Economies

Section 301 is no longer confined to intellectual property disputes with Beijing. Following a judicial shift away from emergency International Emergency Economic Powers Act (IEEPA) measures, the Office of the United States Trade Representative (USTR) pivoted to Section 301 as a legally durable, globally applied enforcement mechanism.

On June 2, 2026, USTR Jamieson Greer finalized determinations against 60 economies for failing to effectively prohibit goods produced with forced labor. To correct the market distortion caused by these practices, the USTR proposed two new ad valorem duty tiers:

These rates are strategically designed to restore the broader baseline tariff levels previously enacted under the IEEPA framework, effectively raising the cost basis for 97% of U.S. goods imports.

Finality for Section 301 Tariffs on China

Importers banking on judicial relief for legacy Section 301 tariffs on China have exhausted their options. As noted earlier, on June 15, 2026, the U.S. Supreme Court formally denied certiorari in HMTX Industries LLC v. United States. By declining to review the U.S. Court of Appeals for the Federal Circuit's decision, the Supreme Court effectively ended the multi-year refund litigation. This ruling definitively cements the legal authority of the existing tariffs on Chinese imports, confirming that these duties are permanent under current trade law.

The Section 301 Exclusions List and Exemption Outlook

The pathway to securing exemptions is narrowing, with the administration prioritizing broad enforcement over corporate carve-outs. While the USTR's June 2026 proposal includes an annex of product-specific exclusions for the new forced-labor tariffs, the baseline criteria are strictly limited to prevent circumvention.

When evaluating the Section 301 exclusions list, the USTR has explicitly carved out only a tight set of categories from the new 10% and 12.5% rates:

• Goods already subject to overlapping Section 232 and 301 tariffs (to prevent double taxation on steel and aluminum).
• USMCA-compliant goods originating natively in North America.
• Specific textile and apparel imports from CAFTA-DR countries.
• Informational materials and humanitarian donations.

Importers consulting a Section 301 tariff lookup must now factor in this 60-country dragnet. Because the USTR intends for these tariffs to protect domestic manufacturing from artificially cheap forced-labor goods, securing new exemptions will require proving an absolute lack of domestic availability. This represents a significantly higher burden of proof than importers faced during prior administrative cycles.

FAQs about section 301 tariffs

What are the Section 301 tariffs?

Section 301 tariffs are trade penalties authorized by Section 301 of the U.S. Trade Act of 1974. They allow the government to impose duties on foreign countries that engage in unfair trade practices, such as intellectual property theft or discriminatory trade policies. In recent years, these tariffs have been most prominently applied to a wide range of goods imported from China.

What is the difference between 232 and 301 tariffs?

The primary difference lies in the legal justification used to implement the trade penalties. Section 232 tariffs are imposed under the Trade Expansion Act of 1962 to restrict imports that are deemed a threat to U.S. national security, such as foreign steel and aluminum. In contrast, Section 301 tariffs are used specifically to penalize foreign nations for unfair, unreasonable, or discriminatory trade practices.

Are the Section 301 tariffs still in effect?

Yes, Section 301 tariffs are still actively in effect as of 2026. The Office of the U.S. Trade Representative (USTR) continues to enforce them and has recently expanded its investigations to propose new tariffs targeting issues like forced labor and manufacturing overcapacity across multiple countries.

How to avoid Section 301 tariffs?

Importers can legally mitigate or avoid these tariffs by applying for product-specific tariff exclusions granted by the USTR. Companies often alter their supply chains by relocating manufacturing and sourcing to countries that are not subject to the duties. Other common strategies include utilizing duty drawback programs for re-exported goods, leveraging foreign trade zones, or using tariff engineering to adjust product classifications.

Conclusion

The transformation of Section 301 from a narrow punitive tool into a comprehensive, multi-nation tariff framework fundamentally alters the cost of importing goods into the United States. Domestic businesses bear the immediate financial burden of these duties, making proactive supply chain management and continuous monitoring of the USTR’s regulatory updates essential. As temporary exclusions expire and permanent legal barriers settle into place, companies must adapt their sourcing strategies to maintain competitive margins in an increasingly protectionist global market.
