KORUS — qualifying goods may enter duty-free

Among US trading partners for iron and steel, South Korea plays a notable role, with approximately $169B in total bilateral trade.

The current tariff framework for iron and steel from South Korea reflects the post-SCOTUS landscape: a 10% Section 122 tariff replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The Section 122 tariff is subject to a 150-day statutory time limit and is set to expire approximately July 24, 2026, unless Congress acts to extend or replace it. Importers should monitor legislative developments closely as this deadline approaches.

Iron and Steel (HTS Chapter 72) carry an average MFN duty rate of 1.8% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from South Korea.

South Korea is party to the KORUS, which may provide preferential or duty-free access for qualifying iron and steel. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 72 imported from South Korea include Hot-rolled steel coils, Cold-rolled steel sheets, Steel rebar, Stainless steel, Steel wire, and Steel pipe and tube.
