What This ECCN Covers

ECCN 2B003 controls numerically controlled machine tools specially designed for shaving, finishing, grinding, or honing hardened (Rc 40 or more) spur, helical, and double-helical gears above a defined pitch diameter. Precision gear-cutting equipment is controlled for National Security and Anti-Terrorism reasons because high-quality gearing is essential to advanced propulsion and drivetrain systems.

Who needs to check this?

Gear-machinery manufacturers and exporters of gear grinding, honing, and finishing equipment for large or precision gearing.

Compliance tip

Control depends on the gear pitch diameter and hardness range the machine is designed for — confirm against the entry, as machines for softer or smaller gears may fall outside. Check the NS and AT columns and the License Exception paragraph.
