The Commerce Department said solar power companies from four countries have received subsidies from the Chinese communist regime.
The U.S. Department of Commerce announced on Monday it plans to impose up to 3,521% of solar imports from four Southeast Asian countries to curb unfair trade practices.
“These are one of the first CVD (duty offset) surveys to positively identify businesses receiving cross-border subsidies,” he said.
The tariffs announced on Monday vary widely by company and country. Among the companies affected by tariffs are Jinko Solar, Trina Solar and Solar Long PV Technology, which are linked to Chinese companies.
Cambodian products will face more than 3,521% of their duties as producers choose not to cooperate with the US investigation.
Tariffs still require approval from the International Trade Commission. The International Trade Commission must issue a final injury decision until June 2nd. If the committee rules negatively, no orders will be issued, the department said.
The US Alliance for the US Solar Power Trade Commission, a coalition of US solar manufacturers leading the incident, hailing the final mandatory decision as a “decisive victory” for the US solar industry.
Tim Brightville, the council’s chief attorney, said the department’s decision confirms that “China-led solar companies are tricking the systems, covering US companies, and making their living for American workers.”
The final decision imposed a sudden taxation of around 60 countries identified as the “worst criminal” in the US trade imbalance amid President Donald Trump’s move to impose a minimum of 10% tariff on all trading partners.
After Trump announced a 145% tariff on all Chinese imports, China increased tariffs on US imports to 84-125%. The Chinese administration also halted exports of certain rare earth metals to the United States as part of its retaliation measures.
