Former President Donald Trump is signaling a potential new phase of his "America First" trade agenda, indicating that if he returns to office, his administration would launch fresh investigations into the trade practices of several key U.S. partners. These actions would primarily leverage Section 301 of the Trade Act of 1974, a powerful tool that allows the U.S. to investigate and respond to foreign government practices that are deemed unfair or discriminatory to U.S. commerce. This move suggests a significant expansion of trade enforcement, potentially leading to new tariffs and trade barriers impacting a broad range of imported goods.

The potential investigations target several major trading partners, focusing on specific policies deemed detrimental to U.S. interests. The European Union (EU) could face scrutiny over its digital services taxes and emerging "green subsidies," such as carbon border adjustment mechanisms, which the Trump team views as protectionist. Mexico's energy policies, particularly those affecting U.S. energy companies operating within the country, are also flagged for a potential Section 301 review. Additionally, Canada's dairy and other agricultural policies are under consideration for investigation, reflecting long-standing trade disputes in these sectors.

Beyond these new potential investigations, the former president has also reiterated his stance on trade with China. While his previous administration imposed significant tariffs on Chinese goods, he has indicated a willingness to go further, floating the possibility of a sweeping 60% tariff on all Chinese imports. Importers sourcing goods from the EU, Mexico, Canada, and China should be aware that these are not immediate actions but rather potential policy directions that could be pursued if the political landscape shifts. The specific rates and commencement dates for any new tariffs would only be determined following formal investigations and subsequent determinations by the U.S. Trade Representative (USTR).

Given these signals, importers, customs brokers, and trade compliance officers should proactively monitor developments in U.S. trade policy. It is crucial to understand the potential implications for your supply chains and landed costs. Companies should review their sourcing strategies, assess the origin of their goods, and evaluate the potential impact of new tariffs on profitability and competitiveness. Engaging with industry associations and trade counsel can provide valuable insights and help prepare for potential changes in the global trade environment. Staying informed and agile will be key to navigating any future shifts in trade policy.
