On November 24, 2025, Thailand's Anti-Dumping and Subsidy Consideration Committee issued a final affirmative determination against aluminum extrusions from China.

Thailand will levy definitive anti-dumping (AD) duties ranging from 5.12% to 21.94% on the CIF value of the Chinese products for a period of five years. Two companies, Guangdong Weiye Aluminium Factory Group Co., Ltd. and Jiangsu Asia-Pacific Light Alloy Technology Co., Ltd., were exempt from the duty.

The duties are effective from the day following the announcement.

The initial investigation was started in July 2024, following the application filed by domestic companies.
