Standing Office 81

4A003"Digital computers", "electronic assemblies", and related equipment therefor, as follows and specially designed components therefor:

List
EU dual-use list – Annex I to Regulation (EU) 2021/821, updated annually
Originating regime
Thỏa ước Wassenaar
Note 1:
4A003 includes the following:
—
'Vector processors';
—
Array processors;
—
Digital signal processors;
—
Logic processors;
—
Equipment designed for "image enhancement".
Note 2:
The control status of the "digital computers" and related equipment described in 4A003 is determined by the control status of other equipment or systems provided:
a. The "digital computers" or related equipment are essential for the operation of the other equipment or systems;
b. The "digital computers" or related equipment are not a "principal element" of the other equipment or systems;
and
N.B.1.
The control status of "signal processing" or "image enhancement" equipment specially designed for other equipment with functions limited to those required for the other equipment is determined by the control status of the other equipment even if it exceeds the "principal element" criterion.
N.B.2.
For the control status of "digital computers" or related equipment for telecommunications equipment, see Category 5, Part 1 (Telecommunications).
c. The "technology" for the "digital computers" and related equipment is determined by 4E.
a. Not used;
b. "Digital computers" having an "Adjusted Peak Performance" ("APP") exceeding 70 Weighted TeraFLOPS (WT);
c. "Electronic assemblies" specially designed or modified for enhancing performance by aggregation of processors so that the "APP" of the aggregation exceeds the limit specified in 4A003.b.;
Note 1:
4A003.c. controls only "electronic assemblies" and programmable interconnections not exceeding the limit specified in 4A003.b. when shipped as unintegrated "electronic assemblies".
Note 2:
4A003.c. does not control "electronic assemblies" specially designed for a product or family of products whose maximum configuration does not exceed the limit specified in 4A003.b.
d. Not used;
e. Not used;
f. Not used;
g. Equipment specially designed for aggregating the performance of "digital computers" by providing external interconnections which allows communications at unidirectional data rates exceeding 2,0 Gbyte/s per link.
Note:
4A003.g. does not control internal interconnection equipment (e.g. backplanes, buses), passive interconnection equipment, 'network access controllers' or 'communications channel controllers'.
Technical Notes:
For the purposes of 4A003.g. Note:
1. A 'network access controller' is a physical interface to a distributed switching network. It uses a common medium which operates throughout at the same "digital transfer rate" using arbitration (e.g., token or carrier sense) for transmission. Independently from any other, it selects data packets or data groups (e.g., IEEE 802) addressed to it. It is an assembly that can be integrated into computer or telecommunications equipment to provide communications access.
2. A 'communications channel controller' is the physical interface which controls the flow of synchronous or asynchronous digital information. It is an assembly that can be integrated into computer or telecommunications equipment to provide communications access.
