U.S. Supreme Court ruled that imported low enriched uranium processed outside the United States is subject to anti-dumping laws, since it can be considered "goods" rather than "services". The ruling in two consolidated cases - U.S. v. Eurodif and USEC Inc., v. Eurodif - reversed an earlier decision of the Court of Appeals for the Federal Circuit, which ruled that enrichment is a service.
