U.S. Polysilicon Tariffs Split Korean Industry: Semiconductor Burden, Solar Opportunity

What happened

The U.S. imposed Section 232 tariffs on polysilicon and derivatives, including a 15% tariff on wafers. Korean firms reacted differently: SK Siltron (semiconductor wafers) fears higher costs and market shrinkage; OCI (polysilicon) expects windfall gains as Chinese products become less competitive; Hanwha Q CELLS sees short-term cost burdens but potential long-term benefits from U.S. local production expansion. The Korean government is gathering industry feedback and seeking clarification from the U.S.

Why it matters

The tariffs could alter global supply chains, impacting Korea's semiconductor and solar exports. U.S. onshoring incentives and tax credits (like 45X AMPC) may prompt Korea to introduce similar support measures. The industry is watching whether such trade measures could extend to other advanced sectors, affecting Korea's industrial competitiveness.
