What This ECCN Covers

ECCN 2B121 controls positioning tables (equipment capable of precise rotary position in any axis), other than those controlled by 2B120, meeting the entry's criteria. These precision rotary stages support inertial-component testing and are controlled for Missile Technology and Anti-Terrorism reasons.

Who needs to check this?

Suppliers of precision rotary positioning tables and the test and calibration labs that use them.

Compliance tip

Rule out 2B120 first, then confirm the positioning accuracy against 2B121. With MT among the reasons, verify the Country Chart and screen for guidance/inertial end uses.
