United States v. Eurodif S. A.

Summary

The Court held that the Commerce Department may reasonably treat transactions under SWU contracts, where utilities provide feed uranium plus cash in exchange for enriched uranium, as sales of goods subject to antidumping duties under the Tariff Act of 1930. The Court found the statute ambiguous and deference proper under Chevron, concluding the economic reality of the transactions supported the agency's interpretation. Justice Souter delivered the opinion.
