C2.5.1. Materiel Notices inform countries of events that impact their ability to acquire or support an item through Foreign Military Sale (FMS). They normally call for submission of a LOR officially requesting the items or associated support. IAs prepare notice messages or letters when U.S. production of an item is scheduled to end, or the United States is making a periodic buy of items that may have foreign demand. The IA coordinates proposed notices with the involved DoD Components and then with DSCA (which in turn coordinates with the DoS prior to release. Correspondence should include a rationale for issuing the notification, the deadline for receipt of an LOR, and the final date for acceptance of the LOA. Notices are sent only to countries that have shown interest in the items and are eligible to purchase the items under the National Disclosure Policy (NDP) as implemented in DoD Directive 5230.11, Disclosure of Classified Military Information to Foreign Governments and International Organizations. “Interest” includes previous purchase (via FMS or commercial), request for Price and Availability (P&A) data, or purchase of related weapon systems that use the items.
