Solar imports from India, Indonesia, Laos injured US manufacturers: ITC

A federal trade panel has found that solar panel imports from India, Indonesia and Laos have hurt U.S. solar manufacturers, a decision that sets up new tariffs on panel components from those countries. The U.S. International Trade Commission's vote follows a similar finding last month from the Commerce Department, which is now expected to finalize the tariffs, called anti-dumping and countervailing duties, around November 2. Rates could be steep: one trade group representative cited dumping margins of 123% and countervailing duty rates of 126% on Indian imports alone.

This follows an earlier, similar case in 2023 that targeted Malaysia, Thailand, Cambodia and Vietnam, after manufacturers were found to be routing Chinese-made solar parts through those countries to dodge tariffs. Backers of the new tariffs say companies had shifted the same tactic to India, Indonesia and Laos, and that closing this path may just push the workaround elsewhere. They point to Ethiopia, where solar imports have surged more than 3,000% in the past year, as a likely next target for scrutiny.

For homeowners, the practical effect is uncertainty around solar panel pricing and supply. Tariffs like these have historically raised costs or tightened availability for panels made with components from targeted countries, though it is not yet clear how soon or how much any price changes might reach the retail market. A separate federal tariff on polysilicon, a raw material used in solar cells, is set to take effect December 4, which could also factor into future panel costs.
