U.S.-China solar cell trade case (2012)
The United States imposed antidumping and countervailing duties on solar cells made in China after finding that Chinese producers benefited from unfair subsidies and sold below fair value. China responded with its own duties on American polysilicon, a key solar input.
The duties raised prices for solar developers and split the supply chain between cells made in China and cells assembled elsewhere.
The case became a template for clean-energy trade disputes and pushed some manufacturing steps into Southeast Asia.
It shows how a narrow product case can escalate into retaliation and reshape where a product is made.
