In a judgment issued on August 22 of last year, the U.S. Court of International Trade (CIT) ruled that the Biden administration’s two-year suspension of anti-dumping/countervailing duty collections on solar products was illegal. This ruling allowed for retroactive tariffs to be collected on billions of dollars of these products imported from Chinese producers in Southeast Asia. The ruling has been appealed to the Court of Appeals for the Federal Circuit (CAFC), with opening briefs in the case setting out the legal arguments of the producers.
