What This ECCN Covers

ECCN 4A090 controls computers, "electronic assemblies," and related equipment that meet defined advanced-computing parameters — the computer-level companion to the advanced integrated-circuit control in 3A090. It is part of the layered U.S. controls on advanced computing and is controlled for Regional Stability and Anti-Terrorism reasons.

Who needs to check this?

Makers and exporters of servers, accelerators, and computing systems built around advanced ICs, and the integrators and datacenters that deploy them.

Compliance tip

The 4A090 parameters track the 3A090 chip thresholds and the related country-specific and §744.23 end-use rules, which have changed repeatedly — check the current entry and latest BIS rules rather than older figures. Treat advanced-computing or supercomputing end uses as license-required pending review.
