How to Import Steel from South Korea to the US
Importing Steel, Iron & Metal Products from South Korea
Importing steel from South Korea into the United States carries medium compliance risk, with an effective duty rate of Section 232 TRQ under KORUS: 0% within quota; 25% above. A Section 232 Tariff Rate Quota (TRQ) arrangement applies: steel and aluminum products within quota limits may enter at reduced or zero Section 232 duty, while above-quota imports face the full 25% surcharge.
Steel imported from South Korea to the United States is subject to CBP entry requirements, applicable HTS-based duty rates, and agency compliance clearances. This guide covers the complete import process for 2026.
South Korea negotiated a Section 232 TRQ during KORUS renegotiation (2018). Within quota: 0% Section 232. Above quota: 25%. Quota volumes are substantial but capped. POSCO and Hyundai Steel are major exporters.

US Compliance Requirements for Steel Imports
Regardless of origin country, steel imports must satisfy the following US regulatory requirements before or at the time of CBP entry filing:
- Section 232 national security tariffs: 25% on most steel, 10% on aluminum — stacks on MFN base rate
- Antidumping and countervailing duty (AD/CVD) orders active on steel from many countries — check Commerce enforcement database
- Country of origin must reflect where steel was melted and poured — transshipment through third countries heavily scrutinized by CBP
- Mill certificates (chemistry, mechanical properties, heat number) required for most structural steel imports
