The U.S. Commerce Department is set to issue a preliminary ruling on potential anti-subsidy duties targeting solar imports from India, Indonesia and Laos.
The decision follows a trade complaint filed by the Alliance for American Solar Manufacturing and Trade, representing parts of the U.S. solar sector.
Officials will assess whether manufacturers in the three countries benefited from unfair government subsidies that disadvantage American producers.
A separate ruling next month will determine whether companies dumped products in the U.S. market at below-cost prices.
Alliance members include South Korea’s Hanwha Qcells and U.S.-based First Solar, both investing heavily in domestic production.
The petition alleges Chinese firms shifted output to Indonesia and Laos after earlier U.S. tariffs targeted other Southeast Asian nations.
The group also accuses Indian manufacturers of selling low-cost panels in the U.S., undermining local investments.
Commerce is expected to issue final determinations later this year, a move that could reshape the U.S. solar supply chain.
