USITC finds material injury from solar imports from India, Indonesia, and Laos

The U.S. International Trade Commission has ruled that solar cells and panels imported from India, Indonesia, and Laos are hurting American solar manufacturers, clearing the way for steep new tariffs on those imports. The U.S. Department of Commerce is expected to issue formal tariff orders in early November 2026, with combined duty rates reaching as high as 249% for India, 268% for Indonesia, and 219% for Laos. These tariffs will stack on top of existing trade duties already in place, not replace them.

The case was brought by a coalition of U.S. solar manufacturers, including First Solar, Hanwha Qcells USA, and Mission Solar Energy, who argued that these countries were selling panels below fair value and benefiting from government subsidies. It follows an earlier round of similar tariffs placed on solar imports from Cambodia, Malaysia, Thailand, and Vietnam.

For homeowners, this is worth knowing mainly because it could affect the price of solar panels and installation in the coming months. Tariffs raise the cost of importing cells and panels from these countries, and that cost can get passed along to buyers. If you are planning a solar installation, it may be worth asking your installer where their panels come from and whether pricing is expected to change once the new duties take effect. The tariffs themselves do not apply retroactively to panels already installed on existing homes.
