What This ECCN Covers

ECCN 2A101 controls radial ball bearings having all tolerances specified in accordance with the ISO standard and the dimensional limits in the entry. Precision bearings of this class have missile-relevant applications, so they are controlled for Missile Technology and Anti-Terrorism reasons.

Who needs to check this?

Bearing manufacturers and distributors exporting precision radial ball bearings within the specified tolerance and size range.

Compliance tip

Confirm the bearing's tolerance class and dimensions against the entry; bearings outside the range may be 2A991 (AT-only) instead. With MT among the reasons, verify the Country Chart and screen for missile-related end uses.
