In its meeting last Friday, the commission determined there is a reasonable indication that a US industry is “materially injured” by imports of CSP cells, whether or not assembled into modules, from the four countries.

In its statement, the USITC said the products are allegedly sold in the US “at less than fair value and subsidised” by the governments of Malaysia, Thailand, Cambodia and Vietnam.

The vote was taken during a meeting attended by four commissioners including chairman David S Johanson, the statement said.

The USITC had commenced an inquiry in response to petitions filed in April by several US companies with the US Department of Commerce and the commission.

The Department of Commerce is conducting its own anti-dumping and countervailing duty investigations of imports of solar cells and modules from the four Southeast Asian countries.

As a result of the commission’s decision, the Department of Commerce will continue its investigations with its preliminary countervailing duty determinations due on or about July 18, 2024, and its preliminary anti-dumping duty determinations due on or about Oct 1, 2024.
