An American solar manufacturing group is asking the United States to open a trade investigation into imports of solar cells from South Korea. The group, American Manufacturers for Energy Resilience, requests an anti-circumvention probe focused on whether certain shipments are being rerouted to avoid existing or expected US tariffs.

According to reports, the petition targets Hanwha’s Qcells, which the group says has shifted cell production from China to South Korea. The request alleges this change in manufacturing location is aimed at circumventing US trade measures rather than reflecting a genuine move in production capacity.

The outlets covering the development describe the filing as a tariff probe related to solar cell imports, with the central question being whether South Korean production is used to evade US duties. The sources do not indicate at this stage what specific products, tariff measures, or timelines the investigation would cover, nor do they provide responses from the company named in the request.
