“Section 731 of the Tariff Act of 1930 calls for ‘antidumping’ duties on ‘foreign merchandise’ sold in the United States at ‘less than its fair value,’ 19 U.S.C. § 1673, but does not touch international sales of services. These cases test the application of this antidumping provision to imports of low enriched uranium (LEU), a highly processed derivative of natural uranium used as nuclear fuel, when domestic utilities contract to obtain LEU for cash plus unenriched uranium delivered to a foreign enricher. Although the parties’ contracts call these transactions sales of uranium enrichment services, the Commerce Department treats them as sales of ‘foreign merchandise’ subject to the antidumping provision. The issue is whether the Commerce Department’s way of seeing the transactions as sales of goods rather than services reflects a permissible interpretation and application of § 1673.”
“We hold that it does. . . . Where a domestic buyer’s cash and an untracked, fungible commodity are exchanged with a foreign contractor for a substantially transformed version of the same commodity, the Commerce Department may reasonably treat the transaction as the sale of a good under § 1673.”
