Importer Asks for CCR as Part of Customs Suit on Ammonium Sulfate Isotope

Importer Cambridge Isotope Laboratories told the Court of International Trade in an Aug. 30 letter as part of its customs suit that it filed a request for a changed circumstances review with the Commerce Department. In the customs case, Cambridge Isotopes said an enriched ammonium sulfate isotope was incorrectly placed within the scope of the antidumping and countervailing duty orders on ammonium sulfate from China (see 2304280022). The changed circumstances review concerns the enriched 15N ammonium sulfate isotope (Cambridge Isotope Laboratories v. United States, CIT # 23-00080).
