At ITC Diligence International, we continue to monitor changes surrounding Section 232 tariffs, enacted as part of the Trade Expansion Act of 1962. This authority allows the U.S. government to adjust imports that may affect national security, and in 2025 it has become a major source of new tariff activity.
Companies that manage global supply chains are now dealing with a more complex trade tariff environment, and importers are revisiting their compliance processes to stay prepared.
What Key Tariff Changes Were Made Under Section 232?
Recent actions and big changes reflect a broader use of Section 232:
- Steel & aluminum: In February 2025, new proclamations expanded existing tariffs on steel and aluminum imports.
- Medium- and heavy-duty vehicles & buses: A proclamation issued in October set new tariffs under Section 232. 25 % on certain trucks and key parts, 10 % on buses, effective November
- Ongoing investigations: In September, the U.S. initiated Section 232 probes into medical devices, robotics, industrial machinery and pharmaceuticals.
These actions show that tariffs tied to Section 232 are being applied to raw materials and to finished goods and components.
Why These Developments Matter for Tariff Strategy
Section 232 actions mean importers must re-evaluate duties, supply chains and sourcing strategies:
- Tariff exposure is rising in categories previously regarded as lower-risk, including parts and finished vehicles.
- Products already under trade tariff obligations may now fall into additional national-security duties.
- Customs agents and trade teams must flag Section 232 code triggers, prepare for retroactive liability, and manage tracking systems accordingly.
Tariffs tied to national security concerns often move quickly, which means a single oversight can affect pricing, delivery timelines and landed cost accuracy.
