New US Tariff Strategy: The Global Impact of 301 Investigations

The US administration is building a new tariff regime based on the Section 301 of the Trade Act of 1974, following the Supreme Court decision that invalidated IEEPA tariffs. This strategy could generate up to $169 billion in annual revenue, according to estimates based on 2025 import levels.

301 Investigations and Tariff Proposals

On June 2, the Office of the United States Trade Representative (USTR) announced the proposed rates from the first 301 investigation on forced labor. The proposals distinguish between:

  • Countries with import bans on products made with forced labor (10% tariff)
  • Economies that have not honored such commitments (12.5% tariff)

Countries with IEEPA Agreements

Some countries have already negotiated agreements under the IEEPA regime, which could influence the application of new tariffs:

  • United Kingdom, Ecuador, Guatemala, Argentina, El Salvador: subject only to the forced labor investigation, with a proposed tariff of 10%
  • EU, Korea, Japan, Switzerland, and Liechtenstein: agreements that limit tariffs to 15%. The USTR has proposed tariffs between 10% and 12.5%, with possible overlaps on MFN rates
  • Canada and Mexico: excluded from this scenario thanks to USMCA

Economic Impact

Estimates indicate that:

  • Tariffs could generate $34 billion from the EU, $6.3 billion from Japan, $4.3 billion from Korea, and $3.2 billion from Switzerland
  • For countries without reciprocal agreements, a 12.5% tariff could bring an additional $13 billion
  • For countries like Vietnam, Thailand, India, and Malaysia that have renegotiated or postponed agreements, they may face additional tariffs of 10-20%, with a potential of $48 billion extra

The Case of Brazil

Brazil, already subject to 50% IEEPA tariffs, now faces a separate 301 investigation. The USTR has proposed a 25% tariff, which would likely be added to the 12.5% forced labor tariff, generating an additional $6.2 billion.

China's Position

Despite trade tensions, China remains a key player. In 2025, the US collected $92 billion in Chinese tariffs, representing 35% of the total. The tariff strategy towards China aims to:

  • Generate revenue
  • Create negotiating leverage
  • Restructure supply chains

Risks and Uncertainties

The new tariff architecture presents several risks:

  • Possible retaliation from trading partners, especially the EU
  • Uncertainties about the cumulative application of tariffs

While the US administration seeks to strengthen its commercial position, the economic and geopolitical consequences of this strategy remain uncertain.

Implications for Businesses and Mitigation Strategies

The new tariff architecture will not only influence trade relations between nations but will also have a significant impact on companies operating globally. Businesses must prepare to navigate a more complex trade landscape, characterized by:

  • Higher import costs: Companies relying on international supply chains will face additional costs, which may be passed on to consumers or absorbed by profit margins.
  • Supply chain reorganization: Companies may be forced to diversify their suppliers or move production to countries with more favorable tariffs, a process that requires significant time and resources.
  • Regulatory uncertainty: The overlap between different investigations and trade agreements creates an unstable regulatory environment, making it difficult for companies to plan long-term.

To mitigate these risks, businesses can adopt various strategies:

  • Supplier diversification: Identify and establish relationships with suppliers in countries less affected by the new tariffs.
  • Investments in local production: Consider the possibility of moving part of the production to the United States or other markets with lower tariffs.
  • Continuous monitoring of trade policies: Maintain a dedicated team to analyze regulatory developments and lobbying opportunities.

Sectoral Impact

Different sectors will be affected differently by the new tariff strategy. For example:

  • Technology and Manufacturing: Sectors like electronics and automotive, which depend on imported components, could face significant additional costs.
  • Agriculture: Agricultural products could become more expensive, affecting both consumers and producers.
  • Energy: Tariffs on key components could slow down the transition to renewable energy sources.

Geopolitical Perspectives

The new US tariff strategy could have significant geopolitical repercussions. While the US administration seeks to strengthen its commercial position, international partners may respond with:

  • Trade retaliation: The EU has already threatened to impose tariffs on American products in response to protectionist measures.
  • Alternative trade alliances: Countries affected by tariffs may seek to strengthen commercial ties among themselves, reducing dependence on the United States.
  • Global economic instability: The increase in trade barriers could slow down global economic growth and increase uncertainty in financial markets.

Conclusions

The new tariff architecture based on Section 301 represents a significant change in US trade policy. While it offers the opportunity to generate revenue and renegotiate trade agreements, it also presents significant risks for businesses and the global economy. The adaptability of companies and the response of the United States' trading partners will be crucial in determining the long-term impact of this strategy.

For businesses, the key will be to remain agile and proactive, closely monitoring regulatory developments and adapting their sourcing and production strategies accordingly. For governments, the challenge will be to balance the need to protect their economic interests with the risk of triggering a spiral of trade retaliation that could harm the global economy.
