What This ECCN Covers

ECCN 4A001 covers electronic computers and related equipment that exceed certain performance thresholds defined by the Adjusted Peak Performance (APP). This includes general-purpose computers, vector processors, and array processors designed for high-performance computing applications. The control exists because advanced computing power can support weapons design, cryptanalysis, and other sensitive applications.

Who needs to check this?

Exporters of high-performance servers, supercomputing components, and custom computing hardware should verify whether their products exceed the APP thresholds specified in this entry.

Compliance tip

Calculate your system's APP value using the formula in EAR Supplement No. 1 to Part 774. If it exceeds the threshold, a license may be required depending on the destination country.
