What This ECCN Covers

ECCN 3E991 covers "technology" for the development, production, or use of the electronic devices and components in the entry's scope — the Anti-Terrorism companion technology entry for Category 3. As an "E" entry it governs intangible technology, including "deemed exports" to foreign nationals.

Who needs to check this?

Electronics R&D and production teams transferring know-how for the relevant Category 3 commodities across borders or to foreign nationals.

Compliance tip

Map the technology to the commodities the entry references. AT-only control limits licensing to a destination list, but intangible transfers and foreign-national access ("deemed exports") still require analysis; verify the Country Chart.
