Title 50 › Chapter CHAPTER 56— - EXPORT ADMINISTRATION › § 4612
The President must block export licenses and can ban imports when a U.S. person or a foreign person knowingly exports, tries to export, conspires to export, or helps move missile-related items listed in the MTCR Annex in ways that break U.S. export controls or that help a non‑MTCR country build missiles. For U.S. people, if the item is Category II the President must deny missile transfer licenses for 2 years. If the item is Category I the President must deny all relevant export licenses for at least 2 years. For foreign people (after November 5, 1990) the same rules apply, and if the transfer substantially helped a non‑MTCR country’s missile work, the President must ban imports of that person’s products for at least 2 years. The Secretary can seek other penalties. The President can waive sanctions if the product or service is essential to U.S. national security and is from a sole source with no timely alternative. For foreign persons the President can also waive for national security but must tell Congress at least 20 working days ahead and explain why. Transfers allowed by the laws of an MTCR adherent or to end users in MTCR adherent countries are not covered. The Secretary can give advisory opinions; relying in good faith on a favorable opinion protects a person. Import bans have listed exceptions for certain defense contracts, spare parts, maintenance, and prior contracts. It defines: “missile” — a Category I system or similar unmanned delivery system and their special production facilities; “MTCR” — the policy announced April 16, 1987 among the United States, the United Kingdom, the Federal Republic of Germany, France, Italy, Canada, and Japan to restrict missile-related transfers; “MTCR adherent” — a country that follows MTCR rules; “MTCR Annex” — the MTCR Guidelines and Equipment and Technology list; “missile equipment or technology”/“MTCR equipment or technology” — items in Category I or II of the MTCR Annex; “foreign person” — anyone who is not a United States person; “person” — a person, company, organization, or government entity acting like a business (with broader rules for some governments); and “otherwise engaged in the trade of” — roles like freight forwarder, exporter’s agent, consignee, or end user.
