Classification Details
| Category | 4 — Computers |
| Product Group | A — Systems, Equipment & Components |
| Description | Electronic computers and related equipment, having any of the following (see List of Items Controlled), and "electronic assemblies" and "specially designed" "components" therefor. |
| Control Reasons | ATMTNPNS |
| License Exceptions | GBSLVSSTA |
Items Controlled
a. "Specially designed" to have any of the following: a.1. [Reserved] a.2. Radiation hardened to exceed any of the following specifications: a.2.a. A total dose of 5 × 10 3 Gy (Si); a.2.b. A dose rate upset of 5 × 10 6 Gy (Si)/s; or a.2.c. Single Event Upset of 1 × 10 − 8 Error/bit/day;
Related Controls
(1) See also 4A101 and 4A994. Equipment designed or rated for transient ionizing radiation is "subject to the ITAR" (see 22 CFR parts 120 through 130). (2) The act of incorporating a radiation hardened integrated circuit into a computer that is specified under ECCN 4A994 or designated as EAR99 does not, in and of itself, cause the computer to meet the parameters of ECCN paragraph 4A001.a.2.
Items may also be controlled under the ITAR (22 CFR 121) administered by the State Department Directorate of Defense Trade Controls (DDTC).
Related Definitions
For the purposes of integrated circuits in 4A001.a.2, 5 × 10 3 Gy(Si) = 5 × 10 5 Rads (Si); 5 × 10 6 Gy (Si)/s = 5 × 10 8 Rads (Si)/s.
See EAR Part 772 (15 CFR 772) for complete definitions of terms used in the CCL.

Export Control Context
Category 4 covers digital computers, hybrid computers, and related assemblies. High-performance computing equipment is controlled due to its potential use in nuclear weapons design, advanced simulations, and signals intelligence. APP (Advanced Computing) controls were significantly updated in 2022.
