The Department of Homeland Security is expanding its scrutiny of solar companies in the US, asking for information about their supply chains, an indication the Biden administration is poised to toughen enforcement of a ban on products linked to Chinese forced labor.
An extensive questionnaire was sent to companies by US Customs and Border Protection earlier this month, according to two people familiar with the matter, marking a widening effort to seek disclosure about the provenance of modules, panels and other products. Previously, importers only had to provide such information to the agency if it detained their shipments for inspection.
