South Korea has enacted the K-Steel Act on June 16, 2026, the steel sector's most significant and long-awaited policy achievement, according to the Korean Law Information Center managed by the Ministry of Government Legislation.

This is designed to bolster its competitiveness and accelerate the transition toward carbon neutrality at a time when steelmakers face severe global and domestic pressures.

Under the new Special Act on Strengthening Steel Industry Competitiveness and Carbon Neutral Transition, which took effect on June 17, restructuring-approved steelmakers can bypass the nation's fair-trade law with consent from the trade ministry and the antitrust watchdog, permitting coordinated production cuts, delivery adjustments, joint procurement of energy and raw materials, and collaborative research and development.

Notably, the antitrust waivers apply retroactively to business activities conducted since January 1, 2025.

The legislation sets up a high-level Special Committee for Strengthening Steel Competitiveness, chaired directly by the prime minister, to oversee five-year master plans and annual implementation blueprints. It also introduces a formal low-carbon steel certification system paired with government priority purchasing commitments and designates "low-carbon steel special zones" that will receive targeted infrastructure support for hydrogen, power, and water supply networks.

A central pillar of the act addresses intensifying competition for ferrous scrap. The government is now authorized to build recycling and processing infrastructure, standardize scrap quality grades, diversify import sources and build strategic stockpiles.

Specialized scrap-processing enterprises can receive priority state backing, reflecting industry fears that the shift from blast furnaces to electric arc furnaces that rely heavily on recycled steel could trigger a global raw-material crunch.

Domestic titans have wasted little time. On the same day the law came into force, POSCO held a completion ceremony for a 2.5-million-tonne electric arc furnace at its Gwangyang plant, a 600-billion-won investment that cuts carbon emissions by up to 75% compared with traditional blast-furnace routes, local media reported.

Yet despite the regulatory flexibilities, industry voices have greeted the legislation with measured skepticism. The law lacks direct fiscal incentives, they argued, and fails to address soaring industrial electricity tariffs, which have climbed roughly 75% over the past three years. Unlike the EU and Germany, which offer explicit power-price rebates for energy-intensive manufacturers, Seoul has so far stopped short of comparable relief, leaving steelmakers to shoulder much of the transition cost.

The reprieve is strictly temporary, with the special provisions due to expire on December 31, 2028, though they may be extended once for up to three years following a mandatory necessity review.
