Introduction ------------ Greater use of Sections 122, 232, and 301 would increase uncertainty by expanding the legal routes through which the United States can impose tariffs or trade restrictions. Because these authorities operate under different rationales, timelines, and sectoral scopes, firms and trading partners would face greater difficulty predicting tariff exposure, supply chain costs, and possible retaliation. Contextual background --------------------- Section 122 of the Trade Act of 1974 allows the President to impose temporary import surcharges or quotas in response to fundamental international payments problems. Import surcharges may reach 15% and last up to 150 days unless extended by Congress[1]. Section 232 of the Trade Expansion Act of 1962 allows trade restrictions when imports are found to threaten national security. Investigations may be requested by interested parties or government agencies, or initiated by the Secretary of Commerce[2]. Section 301 of the Trade Act of 1974 allows the United States to investigate and respond to foreign practices considered unreasonable, discriminatory, or burdensome to commerce in the United States. Recent Section 301 activity has focused on structural excess capacity and production across multiple economies and manufacturing sectors[3]. Together, these tools reflect a shift toward more unilateral, security-linked, and corrective trade policy, increasing the risk that trade restrictions are imposed outside ordinary tariff schedules or multilateral dispute processes Why uncertainty would rise -------------------------- ### 1. Tariff policy would become more legally fragmented Greater reliance on Sections 122, 232, and 301 would make tariff exposure harder to predict because each authority rests on a different legal basis. Section 122 is tied to balance-of-payments pressures, Section 232 to national security, and Section 301 to foreign trade practices[1][2][3]. Firms would therefore need to assess not only standard customs rules, but also whether products could later be linked to emergency economic conditions, security concerns, or unfair trade practices. ### 2. More sectors and countries would face potential exposure The scope of affected products and trading partners would likely widen. Section 232 investigations have covered strategic sectors such as semiconductors, pharmaceuticals, critical minerals, trucks, drones, wind turbines, polysilicon, robotics, and industrial machinery[2]. Section 301 investigations into structural excess capacity have covered multiple economies, including China, the European Union, Japan, Korea, India, Mexico, Vietnam, and Singapore[3]. A broader use of Section 301 against multiple trading partners would increase uncertainty over whether the objective is negotiation, deterrence, tariff escalation, or supply chain restructuring[4]. ### 3. Retaliation and policy spillovers would become more likely Expanded use of these authorities would increase the risk of retaliatory tariffs, World Trade Organization disputes, export controls, procurement restrictions, or offsetting industrial subsidies. The value of world goods imports affected by new tariffs and other import measures rose more than fourfold from mid-October 2024 to mid-October 2025, reaching the highest level in over 15 years [5]. In this environment, firms may front-load imports, shift suppliers, hold extra inventory, or delay investment, raising costs even before final measures are imposed[6]. Conclusion ---------- Greater use of Sections 122, 232, and 301 would increase uncertainty by multiplying the legal justifications, sectoral targets, and country exposures associated with US trade restrictions. Section 122 would add uncertainty through temporary emergency measures; Section 232 through broader national security claims; and Section 301 through targeted investigations into foreign trade practices. The cumulative effect would be a more volatile trade environment, with higher planning costs for firms and greater risk of retaliation among trading partners.
