Title 22 › Chapter 72— NUCLEAR PROLIFERATION PREVENTION › Subchapter I— SANCTIONS FOR NUCLEAR PROLIFERATION › § 6301
The President must stop the U.S. government from buying goods or services from any person or company that, on or after the subchapter’s effective date, knowingly and importantly helped others get unsafeguarded special nuclear material or acquire or build nuclear explosive devices by exporting goods or technology. The rule covers the person found responsible, their successors, and related parent, subsidiary, or affiliate companies if they also knowingly helped. “Requisite knowledge” means the person’s state of mind called “knows” in 15 U.S.C. 78dd–2. These procurement sanctions are in addition to any other penalties. If the person is foreign, the President should talk with that person’s government and may delay the sanction up to 90 days (and up to another 90 days if the government is taking steps). Within 90 days of the President’s determination, the President must report to the Senate Foreign Relations and Governmental Affairs Committees and the House Foreign Affairs Committee on those talks and any corrective actions. The main sanction is that the U.S. government cannot enter into contracts to buy from the sanctioned person. The President may allow exceptions for vital defense contracts already in place or needed for national security, sole-source defense items, defense coproduction, contracts made before the announcement, essential spare or component parts and routine servicing when no alternatives exist, technology needed for U.S. production, and medical or humanitarian items. The Secretary of State, with the Secretary of Defense, may give a written advisory opinion to anyone asking whether a proposed activity would trigger the sanction; someone who relies in good faith on a “no” opinion cannot later be penalized for that activity. Sanctions must last at least 12 months. They stop only after the President certifies to Congress that the person has stopped assisting and has given reliable assurances not to do it again. After those 12 months, the President may waive the sanction if continuing it would seriously harm vital U.S. interests, but must notify Congress at least 20 days before the waiver and explain why.
