What This ECCN Covers

ECCN 4D906 controls "software" specially designed or modified for the development or production of the quantum computers and related items controlled by 4A906. Added in the September 2024 quantum-controls rule, it carries a worldwide license requirement for National Security, Regional Stability, and Anti-Terrorism reasons.

Compliance tip

Tie the software to the 4A906 hardware it supports. Review License Exception IEC and the general license that can permit certain "deemed exports" to qualifying foreign nationals; verify the §734.7 "published" exclusion and the current Country Chart.
