What This ECCN Covers

ECCN 6E003 controls specified "other technology" in Category 6 — itemized development or production know-how for certain sensors, lasers, and optical equipment defined in the entry. As an "E" entry it governs intangible technology, including "deemed exports" to foreign nationals, and is controlled for National Security and Anti-Terrorism reasons.

Who needs to check this?

Sensor, laser, and optics R&D teams, and firms transferring related development or production technology across borders.

Compliance tip

6E003 is itemized — only the specific technologies it lists are controlled, so map your know-how to the exact sub-paragraph. Foreign-national access and intangible transfers ("deemed exports") require authorization analysis; verify the NS and AT columns.
