Section 232 Tariff FAQ
What is Section 232?›
Section 232 of the Trade Expansion Act of 1962 allows the President to impose tariffs or quotas on imports that threaten national security. The U.S. used Section 232 to impose a 25% tariff on steel and a 10% tariff on aluminum beginning in 2018, with rates maintained and expanded through 2025.
Do Section 232 tariffs apply to Canada and Mexico?›
Yes. While Canada and Mexico were temporarily exempted, those exemptions ended. As of 2025, Section 232 tariffs apply to steel and aluminum imports from Canada and Mexico at the standard 25%/10% rates. USMCA/CUSMA does not exempt products from Section 232 duties.
What is the South Korea TRQ?›
South Korea negotiated a Tariff-Rate Quota (TRQ) arrangement for steel imports. Within an agreed-upon quota volume, steel enters the U.S. at 0% Section 232 duty. Imports above that quota face the standard 25% rate. Quota availability resets periodically — verify current status with your customs broker.
How do Section 232 and Section 301 tariffs interact for China?›
Both tariffs can apply simultaneously to the same shipment. Section 232 tariffs apply based on the product (steel/aluminum), while Section 301 tariffs apply based on country of origin (China) and HTS code. The rates stack additively, which can push effective duty rates well above 30% for Chinese steel or aluminum products.
Are there product exclusions from Section 232?›
Yes. The Commerce Department has granted product-specific exclusions for certain HTS codes where domestic supply is insufficient. Exclusions must be applied for and are product-specific. Check the Federal Register and Commerce Department portal for current exclusion status on your specific products.
