Malaysia launched an anti-dumping (AD) investigation targeting flat-rolled products of non-alloy steel plated or coated with aluminum and zinc from China, Taiwan, and Vietnam.

The Ministry of Investment, Trade and Industry (MITI) acted on a petition filed by domestic producer NS Bluescope Malaysia Sdn Bhd on June 19. The application alleged that foreign manufacturers exported these materials below domestic market prices, creating material injury to local competitors.

The authorities established the investigation period spanning from January 1, 2023, through December 31, 2025. A preliminary determination will be made within 120 days of the initiation. An affirmative preliminary ruling will trigger provisional AD duties to stop further injury to the domestic industry.

The subject goods are under HS codes 7210.61.11 00, 7210.61.12 00, 7210.61.91 00, 7210.61.92 00, 7210.61.99 00, 7212.50.23 00, 7212.50.24 00, 7212.50.29 00, 7225.92.90 00, 7225.99.90 00, 7226.99.19 00, and 7226.99.99 00.

Interested parties must submit written responses and evidence by August 17, 2026.
