What This ECCN Covers

ECCN 4A101 controls analog computers, "digital computers," or digital differential analyzers, other than those controlled by 4A001, that are designed or modified for use in missile applications as defined in the entry (for example, ruggedized for severe environments). Because of that missile relevance it is controlled for Missile Technology and Anti-Terrorism reasons.

Who needs to check this?

Suppliers of ruggedized or environment-hardened computers that could meet the missile-related criteria in the entry.

Compliance tip

Rule out 4A001 first, then check the environmental/ruggedization criteria in 4A101. With MT among the reasons, license exceptions are limited — verify the Country Chart and apply Part 744 missile end-use diligence.
