The Customs Administration of Taiwan's Ministry of Finance announced temporary four-month anti-dumping (AD) duties on cold-rolled, flat-rolled non-oriented electrical steel products from South Korea and China, starting June 8, 2026.

Joint preliminary findings by the Ministries of Finance and Economic Affairs confirmed dumping practices that caused material injury to the domestic industry. These provisional measures protect local producers during the ongoing investigation.

Duty rates vary by origin and manufacturer. South Korean steelmaker POSCO, together with exporters POSCO International Corporation, Donghwa Corporation, Hyosung TNC Corporation, and Toyota Tsusho Korea Corporation, faces a 45.68% duty, with all other South Korean firms receiving a 49.84% rate. Chinese exporters uniformly face a 26.44% duty.

The Ministry of Finance expects to issue a final determination within 60 days of the preliminary announcement.
