Related controls

(1) Electronic items that are enumerated in USML Category XI or other USML categories, and technical data (including software) directly related thereto, are subject to the ITAR. (2) Application specific integrated circuits (ASICs) and programmable logic devices (PLD) that are programmed for defense articles that are subject to the ITAR are controlled in USML Category XI(c)(1). (3) See ECCN 3A001.a.7 for controls on unprogrammed programmable logic devices (PLD). (4) Printed circuit boards and populated circuit cards with a layout that is “specially designed” for defense articles are controlled in USML Category XI(c)(2). (5) Multichip modules for which the pattern or layout is “specially designed” for defense articles are controlled in USML Category XI(c)(3). (6) Electronic items “specially designed” for military application that are not controlled in any USML category but are within the scope of another “600 series” ECCN or a 9x515 ECCN are controlled by that “600 series” ECCN or 9x515 ECCN. For example, electronic components not enumerated on the USML or a “600 series” other than 3A611 that are “specially designed” for a military aircraft controlled by USML Category VIII or ECCN 9A610 are controlled by the catch-all control in ECCN 9A610.x. Electronic components not enumerated on the USML or another “600 series” entry that are “specially designed” for a military vehicle controlled by USML Category VII or ECCN 0A606 are controlled by ECCN 0A606.x. Electronic components not enumerated on the USML that are “specially designed” for a missile controlled by USML Category IV are controlled by ECCN 9A604.(7) Certain radiation-hardened microelectronic circuits are controlled by ECCN 9A515.d or 9A515.e, when “specially designed” for defense articles, “600 series” items, or items controlled by 9A515.

Notes

Note to 3A611.a: ECCN 3A611.a includes any radar, telecommunications, acoustic or computer equipment, end items, or systems “specially designed” for military application that are not enumerated or otherwise described in any USML category or controlled by another “600 series” ECCN.

Note to 3A611.e: ECCN 3A611.e does not apply to systems, equipment, and assemblies “specially designed” for marine traffic control.

Note to paragraph .f: In this paragraph, the term 'application specific integrated circuit' means an integrated circuit developed and produced for a specific application or function regardless of number of customers for which the integrated circuit is developed or produced.

Note 1 to ECCN 3A611.x: ECCN 3A611.x includes “parts,” “components,” “accessories,” and “attachments” “specially designed” for a radar, telecommunications, acoustic system or equipment or computer “specially designed” for military application that are neither controlled in any USML category nor controlled in any paragraph other than the .x paragraph of another “600 series” ECCN.

Note 2 to ECCN 3A611.x: ECCN 3A611.x controls “parts” and “components” “specially designed” for underwater sensors or projectors controlled by USML Category XI(c)(12) containing single-crystal lead magnesium niobate lead titanate (PMN-PT) based piezoelectrics.

Note 3 to ECCN 3A611.x: “Parts,” “components,” “accessories,” and “attachments” subject to the EAR and within the scope of any 600 series .x entry that are of a type that are or would potentially be for use in or with multiple platforms (e.g., military electronics, military vehicles, and military aircraft) may be classified under 3A611.x.

Note to ECCN 3A611: When applying the “specially designed” definition to determine whether a printed circuit board, populated circuit card assembly or multichip module is controlled by paragraph .g, .h, .y.15 or .y.16 of this entry, the layout of the board or assembly and the pattern and layout of the module are the only characteristics that need be evaluated under the “specially designed” definition.
