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 foreign or U.S. person if the President finds in writing that, on or after this law started, that person helped, by exporting goods or technology from the United States or another country, a person, group, or non‑nuclear‑weapon state try to get unsafeguarded special nuclear material or to make, use, produce, or stockpile a nuclear explosive device. The ban covers the named person, any successor company, parents or subsidiaries that knowingly and meaningfully helped, and affiliates that are controlled by and knowingly helped the person. The President is urged to talk right away with the foreign government that has primary authority over a foreign person. The President may delay the ban up to 90 days to hold talks, and may delay another 90 days if that government is trying to fix the problem. The President must report to the Senate Foreign Relations Committee, the Senate Governmental Affairs Committee, and the House Foreign Affairs Committee within 90 days on those talks and any decision to delay. The main punishment is a government procurement ban, but there are exceptions for certain defense contracts (including existing contracts and vital sole‑source items), contracts made before the President announced an intent to impose the ban, essential spare or component parts and maintenance when no alternatives exist, essential information or technology for U.S. production, and medical or humanitarian items. The Secretary of State, with the Secretary of Defense, may give written advisory opinions on whether an activity would cause the ban; someone who relies in good faith on a written opinion saying it would not be subject cannot later be punished for that activity. The ban lasts at least 12 months. After that, it ends only if the President certifies to Congress that the person stopped helping and has given reliable assurances they will not do so again. The President may waive the ban after the 12 months if keeping it would seriously harm vital U.S. interests, but must tell Congress at least 20 days before the waiver and explain why.
