What This ECCN Covers

ECCN 9D990 covers "software," not elsewhere specified, for the development or production of the equipment controlled by 9A990 or 9B990 — the Anti-Terrorism companion software entry for those commercial engine and test items. As an AT-only entry, it reaches a limited set of destinations.

Who needs to check this?

Vendors of development and production software for the diesel engines, tractors, and vibration test equipment in 9A990/9B990.

Compliance tip

Tie the software to the 9A990 or 9B990 commodity it supports. AT-only control limits licensing to a destination list; verify the §734.7 "published" exclusion and screen all parties.
