What This ECCN Covers

ECCN 4D994 controls "software" — other than that covered by 4D001 — specially designed or modified for the development, production, or use of the Anti-Terrorism-controlled computing commodities (such as 4A994 and related entries). It is an AT-only entry, so it reaches a limited set of destinations.

Who needs to check this?

Suppliers of firmware and control software for AT-level industrial computers and embedded systems that fall outside 4D001.

Compliance tip

Match the software to the exact AT-controlled hardware it supports. AT controls limit licensing to a small list of destinations, but always verify the §734.7 "published" exclusion for publicly available code and screen all parties against the Entity and SDN lists.
