Thailand Aluminum Extrusion Duties 2025
Thailand has confirmed new Thailand aluminum extrusion duties on imports from China. On 24 November 2025, Thailand’s Anti-Dumping and Subsidy Committee issued a final decision to impose definitive anti-dumping tariffs on Chinese aluminum extrusions. The measures apply for five years and are calculated as a percentage of the CIF value.
Background to Thailand’s Anti-Dumping Decision
The case began on 16 July 2024. Thailand opened an anti-dumping investigation after a formal petition from domestic aluminum producers. Local companies argued that low-priced aluminum extrusions from China were undercutting their sales.
This ruling follows an earlier investigation completed in June 2023. At that time, authorities confirmed dumping but found no material injury to Thai industry. As a result, no measures were imposed in 2023. The latest data, however, led to a different conclusion and to new Thailand aluminum extrusion duties on Chinese imports.
Duty Rates for Chinese Exporters
The final duty rates range from 5.12% to 21.94% of the CIF value. Different Chinese producers face different tariff levels based on the investigation findings.
Guangdong Golden Aluminum Co., Ltd. received the lowest rate at 5.12%. Guangdong Yonglong Aluminum Co., Ltd. was assigned a duty of 7.53%. Several suppliers, including Qingyuan XinYueYa Aluminum Industry Co., Ltd., face a 7.63% tariff.
A separate rate of 7.09% applies to cooperating but non-sampled producers. This group includes major names such as Foshan Sanshui Fenglu Aluminium Co., Ltd. and Guangdong XingFa Aluminium Co., Ltd. All other Chinese exporters not specifically listed will face the highest duty level of 21.94%.
Exempted Producers and Product Scope
Two Chinese companies are exempt from the anti-dumping duties. Guangdong Weiye Aluminium Factory Group Co., Ltd. and Jiangsu Asia-Pacific Light Alloy Technology Co., Ltd. will continue exporting without additional AD tariffs. Their shipments are subject only to normal customs rules.
The measures cover aluminum extrusions imported from China under specified Thai customs codes. These include codes such as 7604.10.10.000 and 7610.10.10.000, together with related subheadings. The duties take effect from 25 November 2025, the day after the official announcement.
Global Trade Context and Market Impact
Thailand’s move is part of a wider global trend in aluminum trade remedies. Several economies have introduced anti-dumping or countervailing duties on aluminum extrusions. The United States, for example, recently announced preliminary anti-dumping actions on imports from multiple countries, including China.
These measures reflect growing concerns over excess capacity, price undercutting and unfair trade practices. For Chinese exporters, the Thailand anti-dumping duties China aluminum extrusions ruling adds to a more complex global market. For Thai producers, the decision aims to restore fair competition and protect local jobs and investment.

Businesses should also verify the correct customs codes and ensure accurate declarations at the time of import.
Maintaining clear documentation for origin, producer identity and invoice values is critical. Failure to declare products correctly can lead to penalties, back-duties or shipment delays.
