22 U.S.C. § 2797a — Denial of transfer of missile equipment or technology by United States persons

(a)(1) If the President determines that a United States person knowingly exports, transfers, or trades an MTCR Annex item in violation of the listed laws or their regulations or orders, conspires or tries to do so, or helps another person do so, the President must impose (2)'s sanctions. (2)(A) For Category II missile equipment or technology, the President must deny the person for two years United States Government contracts concerning missile equipment or technology and licenses to transfer chapter-controlled missile equipment or technology. (B) For Category I equipment or technology, the President must deny for at least two years all United States Government contracts and all export licenses and agreements for United States Munitions List items. (b) The President may also pursue any penalty under section 2778(c). (c) For applying sanctions, there is a rebuttable presumption that an item is designed for an MTCR-listed missile if the President finds its final destination is a country whose government the Secretary of State has determined, for the cited title 50 purpose, repeatedly supported international terrorism. (d) The President may waive sanctions for a product or service if the President certifies to Congress that it is essential to United States national security and the person is its sole-source supplier, no reliable alternative is available, and improved manufacturing or technology cannot meet the need promptly.
