The South Korean government has announced a significant policy to bolster its critical mineral supply chains.
This move comes at a critical time, largely driven by immediate geopolitical instability. Since late February 2026, repeated disruptions in the Strait of Hormuz, a key global shipping lane, have caused oil prices to spike and created major logistical headaches. With shipping and insurance costs becoming highly volatile, the government's decision to waive import duties provides a much-needed buffer, reducing the baseline landed cost of essential materials for Korean industries precisely when they are most vulnerable to external shocks.
Beyond the immediate crisis, the policy is a strategic response to the escalating tech competition between the U.S. and China. For years, Korea has been navigating China's tightening grip on key materials. Beijing expanded its export controls on rare-earth elements in 2025 and imposed licensing on graphite back in 2023, creating significant supply risks. At the same time, the U.S. Inflation Reduction Act (IRA) includes Foreign Entity of Concern (FEOC) rules, which penalize electric vehicles using minerals from entities linked to China. Korea's tariff waiver perfectly addresses both pressures; it incentivizes companies to develop their own supply chains outside of China, aligning with U.S. policy while reducing dependence on a single supplier.
The need for this diversification is acute. In recent years, Korea's reliance on China for materials like graphite has been over 90%. To counter this, Korean companies like POSCO have been building up domestic processing capabilities, such as lithium hydroxide plants in Gwangyang. The new tariff exemption is designed to connect these domestic facilities with a stable, Korean-controlled upstream supply. By making it cheaper to bring home minerals from overseas mines developed by Korean firms, the policy encourages more direct investment and offtake agreements abroad.
The economic impact, while not a silver bullet, is tangible. Waiving tariffs of 3-8% could save Korean companies an estimated $15 to $160 million annually, depending on the volume of imports. For battery manufacturers, this could translate to a margin improvement of up to 1.28 percentage points. This policy operationalizes a legal change made in late 2025, which created the framework for such tariff relief, demonstrating a planned, strategic rollout by the government. It's a clear signal that Korea is using every tool at its disposal to de-risk its economy.
