What This ECCN Covers

ECCN 4A994 is the Anti-Terrorism companion entry for computers, "electronic assemblies," and related equipment not controlled by 4A001 or 4A003 — including computers essential to the operation of other controlled equipment and certain robotics-related controllers. As an AT-only entry, it applies to a limited set of destinations rather than worldwide.

Who needs to check this?

Exporters of industrial computers, embedded controllers, and related equipment who have confirmed the item is not caught by 4A001 or 4A003.

Compliance tip

AT-only control means most destinations need no license, but terrorism-designated destinations are restricted and may also fall under OFAC programs. Screen the end user and end use against the Entity and SDN lists regardless of the low classification.

  • b.The "digital computers" or related equipment are not a "principal element" of the other equipment or systems; and
  • B. 1: The control status of "signal processing" or "image enhancement" equipment specially designed for other equipment with functions limited to those required for the other equipment is determined by the control status of the other equipment even if it exceeds the "principal element" criterion.
  • B. 2: For the control status of "digital computers" or related equipment for telecommunications equipment, see Category 5, Part 1 (Telecommunications).
  • c.The "technology" for the "digital computers" and related equipment is determined by 4E.
  • a.Electronic computers and related equipment, and "electronic assemblies" and specially designed "parts" and "components" therefor, rated for operation at an ambient temperature above 343 K (70 °C);
