POSCO Group, a leading steelmaker in South Korea, plans to invest in Hyundai Steel’s new US$5.8 billion steel mill in Louisiana, aligning with its global expansion strategy.

The partnership will also focus on EV battery materials, supporting Hyundai’s goal to sell 3.26 million electric vehicles by 2030.

The plant, set to begin production in 2029, will supply 2.7 million tons of steel annually to Hyundai, Kia, and other US automakers.

POSCO and Hyundai Steel signed an MOU for the project and will explore joint efforts in the steel and rechargeable battery sectors.

POSCO’s exact investment is still under discussion, as the move follows US tariffs on steel imports and supports supply chain localization.

🧠 Food for thought

1️⃣ Tariff-driven manufacturing localization is reshaping the global steel landscape

POSCO’s investment in Hyundai Steel’s U.S. plant represents a broader industry pattern of foreign steelmakers establishing local production to navigate trade barriers.

This strategy follows POSCO’s difficult experience with tariffs, as its joint venture USS-POSCO Industries (UPI) reported losses for six consecutive quarters primarily due to duties of up to 60% on South Korean steel imports1.

The impact of tariffs is quantifiable. Domestic steel prices rose 5% shortly after Trump’s previous tariffs were implemented, changing the economics of steel importing versus local production2.

Other Asian steelmakers have followed similar strategies, with manufacturers shifting from exporting to establishing U.S. manufacturing presence to ensure market access despite trade barriers.

This investment pattern reflects the historical impact of the Section 232 tariffs, which significantly reshaped trade flows and forced international steel producers to reconsider their U.S. market strategies.

2️⃣ Vertical integration between automakers and steel suppliers accelerating in EV era

The POSCO-Hyundai collaboration highlights the deepening integration between automotive and steel industries as they navigate the transition to electric vehicles.

Hyundai Motor Group has set ambitious targets to sell 3.26 million electric vehicles globally by 2030, creating unprecedented demand for specialized steel and battery materials.
