ECCN 4A090
RSATComputers as follows and related equipment, electronic assemblies, and components therefor.
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.
Items Covered
- a.Computers, "electronic assemblies," and "components" containing integrated circuits, any of which meets or exceeds the limits in 3A090.a.
- b.Computers, "electronic assemblies," and "components" containing integrated circuits, any of which meets or exceeds the limits in 3A090.b.
Control Reasons
Items controlled for regional stability reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
