What This ECCN Covers

ECCN 5B991 covers telecommunications test equipment, not elsewhere specified — the Anti-Terrorism companion for commercial telecom test gear below the higher Category 5 Part 1 thresholds. As an AT-only entry, it reaches a limited set of destinations.

Who needs to check this?

Suppliers of protocol analyzers, network and transmission test sets, and other commercial telecom test equipment.

Compliance tip

Rule out the more specific 5B001 first. AT-only control means a license is needed only to a limited destination list; verify the Country Chart and screen all parties against the Entity and SDN lists.
