ECCN 3B992
ATEquipment not controlled by 3B002, 3B993, or 3B994, for the inspection or testing of electronic components and materials, and specially designed parts, components and accessories therefor.
What This ECCN Covers
ECCN 3B992 covers equipment, not controlled by 3B002, 3B993, or 3B994, for the inspection or testing of semiconductor materials and devices, as specified in the entry — the Anti-Terrorism companion for commercial semiconductor inspection/test equipment. As an AT-only entry, it reaches a limited set of destinations.
Who needs to check this?
Suppliers of semiconductor inspection, metrology, and test equipment below the higher-control thresholds.
Compliance tip
Rule out 3B002, 3B993, and 3B994 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.
