What This ECCN Covers

ECCN 4E001 controls "technology" for the development, production, or use of computing equipment and software in Category 4 — including technology for building digital computers above defined "Adjusted Peak Performance" (APP) levels and for processor "aggregation." It captures the design and integration know-how behind high-performance and supercomputing systems, and also covers technology associated with certain network-surveillance items.

Who needs to check this?

High-performance-computing system designers, processor and interconnect engineers, and firms transferring computer-architecture or aggregation know-how across borders or to foreign nationals.

Compliance tip

Like all "E" entries, 4E001 governs intangible technology transfers and "deemed exports." The APP-based sub-paragraphs change as policy evolves, so recompute APP against the current threshold in the entry. Note that the Crime Control reason adds destination restrictions for surveillance-related technology.
