What This ECCN Covers

ECCN 5E001 controls telecommunications "technology" — under the General Technology Note — for the development, production, or use of the equipment, functions, and features controlled in Category 5 Part 1 (notably 5A001 and related entries). Because part of this technology relates to interception capability, the entry carries a Surreptitious Listening reason alongside National Security and Anti-Terrorism.

Who needs to check this?

Telecom R&D and engineering teams, and firms transferring development or production know-how for controlled communications equipment to foreign nationals or partners.

Compliance tip

Map the technology to the specific 5A001 function it supports — controls follow the underlying equipment, and SL-related technology faces broad licensing. Intangible transfers and foreign-national access ("deemed exports") require authorization analysis; verify the License Exception paragraph.
