How the Country Chart Works
The Country Chart in Supplement No. 1 to Part 738 is a matrix that cross-references Reasons for Control (columns) against destination countries (rows). When your item's ECCN lists specific Reasons for Control and an 'X' appears at the intersection with your destination country, a license is required for that export.
Each ECCN entry on the CCL specifies its applicable Reasons for Control. Common reasons include NS (National Security), MT (Missile Technology), NP (Nuclear Nonproliferation), CB (Chemical and Biological Weapons), RS (Regional Stability), and AT (Anti-Terrorism).
Reasons for Control
National Security (NS) is the broadest reason for control and applies to most controlled items. It restricts exports to countries outside U.S. allies. Anti-Terrorism (AT) applies to nearly all controlled items and restricts exports to state sponsors of terrorism. Missile Technology (MT) controls items usable in missile delivery systems and applies to a specific set of ECCNs.
Regional Stability (RS) controls items that could affect military balance in sensitive regions. Nuclear Nonproliferation (NP) and Chemical/Biological Weapons (CB) controls address weapons of mass destruction proliferation concerns.
Practical Application
When determining license requirements, check all Reasons for Control listed in your ECCN entry. If any reason produces an 'X' on the Country Chart for your destination, a license is required. Multiple Reasons for Control may apply simultaneously, and the most restrictive requirement governs.
Country Groups (listed in Supplement No. 1 to Part 740) categorize countries for license exception purposes. These groups do not directly correspond to Country Chart entries but are referenced by specific license exceptions to define eligible destinations.
