U.S.-China solar panel trade war (2012)
Commerce imposed antidumping and countervailing duties on Chinese solar panels in 2012 after U.S. manufacturers alleged dumping. Chinese producers responded within two years by opening factories in Malaysia, Thailand, and Vietnam to keep serving the U.S. market.
Chinese panel imports fell, but shipments from Southeast Asian plants rose to take their place.
Commerce opened an anti-circumvention inquiry in 2022 and, in 2024, extended duties to panels assembled in Cambodia, Malaysia, Thailand and Vietnam.
The trailer coalition is already warning that trailers assembled in Canada from Chinese subassemblies could dodge today's U.S. orders — a pattern the solar case shows plays out in years, not decades.
