What This ECCN Covers

ECCN 2A991 covers bearings and bearing systems not controlled by 2A001 — the Anti-Terrorism companion entry for commercial bearings that fall below the precision thresholds of 2A001. As an AT-only entry, it applies to a limited set of destinations rather than worldwide.

Who needs to check this?

Bearing manufacturers and distributors exporting commercial bearings that have been ruled out of the precision-controlled 2A001.

Compliance tip

Confirm the bearing's tolerance class is below the 2A001 thresholds first. AT controls require a license only to a limited destination list, but screen the end user and end use against the Entity and SDN lists regardless of the low classification.
