What This ECCN Covers

ECCN 4A003 covers digital computers, assemblies, and related equipment not controlled under 4A001. This is a broad entry that captures computing systems that, while not reaching the highest performance thresholds, still have capabilities warranting export controls for national security and anti-terrorism reasons.

Who needs to check this?

Manufacturers and distributors of commercial computing equipment, especially those shipping to embargoed or sanctioned destinations.

Compliance tip

Many items under 4A003 qualify for License Exception APP or other exceptions. Check the License Exception section carefully before assuming a license application is needed.
