US Commerce Dept imposed preliminary anti-dumping duties of 123% on Indian solar CSPV imports, total 234% with countervailing duties.
Export‑focused firms Waaree Energies and Vikram Solar saw shares fall up to 5%, with Waaree down 2.93% and VIKO down 2.11%.
The duties, based on AASMT petition alleging dumping from India, Laos, Indonesia, create pricing pressure and near‑term revenue uncertainty.
Final decision expected in July, prompting exporters to consider domestic market focus or alternative export destinations.
