According to a preliminary decision published on the US Department of Commerce website on November 29, 2024, the agency has imposed anti-dumping duties ranging from 21.31% to 271.2% on solar panels imported from Cambodia, Malaysia, Thailand and Vietnam.

The American Alliance for Solar Manufacturing Trade Committee filed a complaint in April alleging that major Chinese solar panel manufacturers with factories in Malaysia, Cambodia, Vietnam and Thailand were dumping their products on the market, causing global prices to plummet. The complaint prompted the US Department of Commerce to open an investigation into these imports.

The US Department of Commerce’s decision marks a victory for US solar panel manufacturers. Currently, most of this equipment in the United States is imported from Southeast Asian countries. The US Department of Commerce has released the preliminary results of an independent investigation, saying that solar products imported from Southeast Asia benefit from local government support, which is a form of unfair competition for US companies.

Previously, after the US imposed similar tariffs on solar products imported from China, one of the countermeasures China took was to set up manufacturing plants in some Asian countries that were not affected by US tariffs.
