| The product covered by this order is all LEU. LEU is enriched uranium hexafluoride (UF6) with a U235 product assay of less than 20 percent that has not been converted into another chemical form, such as UO2, or fabricated into nuclear fuel assemblies, regardless of the means by which the LEU is produced (including LEU produced through the down-blending of highly enriched uranium).
Certain merchandise is outside the scope of this order. Specifically, this order does not cover enriched uranium hexafluoride with a U235 assay of 20 percent or greater, also known as highly enriched uranium. In addition, fabricated LEU is not covered by the scope of this order. For purposes of this order, fabricated uranium is defined as enriched uranium dioxide (UO2), whether or not contained in nuclear fuel rods or assemblies. Natural uranium concentrates (U3O8) with a U235 concentration of no greater than 0.711 percent and natural uranium concentrates converted into uranium hexafluoride with a U235 concentration of no greater than 0.711 percent are not covered by the scope of this order.
Also excluded from this order is LEU owned by a foreign utility end-user and imported into the United States by or for such end-user solely for purposes of conversion by a U.S. fabricator into uranium dioxide (UO2) and/or fabrication into fuel assemblies so long as the uranium dioxide and/or fuel assemblies deemed to incorporate such imported LEU (i) remain in the possession and control of the U.S. fabricator, the foreign end-user, or their designed transporter(s) while in U.S. customs territory, and (ii) are re-exported within eighteen (18) months of entry of the LEU for consumption by the end-user in a nuclear reactor outside the United States. Such entries must be accompanied by the certifications of the importer and end-user.
