§6303 Prohibition on Assisting Nuclear Proliferation Through Provision of Financing

Title 22 › Chapter 72— NUCLEAR PROLIFERATION PREVENTION › Subchapter I— SANCTIONS FOR NUCLEAR PROLIFERATION › § 6303

Last updated Apr 5, 2026|Official source

Summary

Stops anyone from giving money or other financing that they know, in a major way, will directly help get unsafeguarded special nuclear material or help make, develop, produce, stockpile, or otherwise get any nuclear explosive device. If the United States can lawfully stop the person, no U.S. person and no foreign person may do those things. If the President finds that a U.S. person or a foreign person did this, the President must order penalties. Penalties include removing or blocking a person from being a primary dealer in U.S. government debt, banning them from holding U.S. government funds, and stopping them from starting any new U.S. business lines or doing business from any U.S. location they did not use when the order was issued. For foreign persons, the President is urged to consult the foreign government and may delay the order up to 90 days (and up to another 90 days with written certification) while talks continue. The President must report to Congress within 90 days on consultations. Sanctions must last at least 12 months and end only if the President certifies the person stopped and gives reliable assurances they will not do it again. The President can waive sanctions if keeping them would seriously harm financial or payment systems. The Attorney General can go to court to stop violations. “Knowingly” means being aware or firmly believing the circumstance or result, or aware of a high probability unless one actually believes otherwise. The rules apply to activities on or after the subchapter’s start date.
