The Section 232 national security tariff of 25% continues to structure the US flat-rolled steel market. US domestic HRC at $1,116/st commands a premium of approximately $120-170/st over imported material after accounting for the tariff and shipping costs.
Import penetration in the US steel market remains stable at approximately 18% of total consumption, with major suppliers including Canada, Brazil, South Korea, and Mexico. Canada and Mexico, which are subject to Section 232 tariff-rate quotas rather than the full 25% tariff, account for the largest share of imports.
The tariff structure effectively creates a price floor for domestic producers. If domestic prices were to fall significantly, import volumes would decline as foreign suppliers redirect shipments to higher-priced markets, reducing competition and supporting domestic prices.
Trade cases under the antidumping and countervailing duty laws provide additional protection for specific product categories. Recent cases involving corrosion-resistant steel and tin mill products from multiple countries have resulted in additional duties that further support domestic prices.
The possibility of tariff rate adjustments under the new administration is a key risk factor. Any reduction in Section 232 tariff levels would pressure domestic prices as import volumes increased.
Section 232 tariffs provide a structural support for domestic HRC prices. Buyers should model their procurement under both current and potential tariff scenarios. Diversifying supply sources between domestic mills and allies (Canada, Mexico, Brazil) provides optionality.
