The U.S. International Trade Commission (USITC) has made a final affirmative injury determination in its Solar IV investigation, covering crystalline silicon photovoltaic cells, whether or not assembled into modules, from India, Indonesia and Laos, pv magazine reported on 16 October 2026. The vote clears the last legal step for federal trade protection: it finds that dumped and subsidised imports from the three countries cause material injury to domestic solar manufacturers, so the U.S. Department of Commerce will issue antidumping (AD) and countervailing duty (CVD) orders.

The duty rates. Combined tariff rates reach as high as 249% for India, 268% for Indonesia and 219% for Laos. pv magazine reports that these case-specific duties, under the Tariff Act of 1930, stack on top of existing executive tariffs and Section 232 minimum-import-price floors rather than replacing them. The USITC vote locks in margins Commerce set the previous month: for India, dumping margins of 123.04% for all producers plus a countervailing rate of 126.09%; for Indonesia, dumping margins of 94.36% with countervailing rates from 73.2% to 173.7%; for Laos, dumping margins of 65.43% with countervailing rates from 82.03% to 153.67%.

Who brought it and what follows. The cases were filed by the Alliance for American Solar Manufacturing and Trade, with lead petitioners First Solar, Hanwha Qcells USA and Mission Solar Energy. They follow the earlier Solar III orders against Cambodia, Malaysia, Thailand and Vietnam. Commerce is scheduled to issue the official AD and CVD orders in early November 2026; on publication, U.S. Customs and Border Protection will require final duty cash deposits on all incoming cells and modules from the three countries. The commission's full public report (Inv. Nos. 701-TA-772-774 and 731-TA-1756-1758, USITC Publication 5804) is due on the USITC website by 23 November 2026.

This article is based on pv magazine's write-up; the numbers it cites are Commerce's margins and the commission's own determination, and the key dates (orders in early November, report by 23 November) come from that account.
