What is Section 232 and why does it matter for steel, aluminum, and copper imports?

Section 232 of the U.S. Trade Expansion Act allows the president to impose tariffs if imports threaten national security. Since 2018, this has led to significant tariffs on steel and aluminum, and in 2025, copper was added. Importers must now provide detailed supply chain data (such as country of smelt, cast, melt, and pour) to avoid duties up to 200%.

How can importers stay compliant with Section 232 reporting requirements?

Importers should:Collect mill test certificates, certificates of analysis, or supplier attestationsEngage suppliers early to ensure smelt/melt data is availableUse trade compliance software to trace metals back to the smelterWork with compliance experts to interpret CBP updates and avoid costly penalties

What are the risks of not complying with Section 232 tariff requirements?

If importers cannot prove the country of smelt, cast, melt, or pour, U.S. CBP may assume the material originated from a restricted country (such as Russia). This can trigger a 200% duty, shipment delays, or even having goods stopped at the border. Lack of documentation creates significant financial and operational risks.
