PART 121_THE UNITED STATES MUNITIONS LIST--Table of Contents
 
Sec. 121.8  End-items, components, accessories, attachments, parts, 
firmware, software and systems.

    (a) An end-item is an assembled article ready for its intended use. 
Only ammunition, fuel or another energy source is required to place it 
in an operating state.
    (b) A component is an item which is useful only when used in 
conjunction with an end-item. A major component includes any assembled 
element which forms a portion of an end-item without which the end-item 
is inoperable. (Example: Airframes, tail sections, transmissions, tank 
treads, hulls, etc.) A minor component includes any assembled element of 
a major component.
    (c) Accessories and attachments are associated equipment for any 
component, end-item or system, and which are not necessary for their 
operation, but which enhance their usefulness or effectiveness. 
(Examples: Military riflescopes, special paints, etc.)
    (d) A part is any single unassembled element of a major or a minor 
component, accessory, or attachment which is not normally subject to 
disassembly without the destruction or the impairment of design use. 
(Examples: Rivets, wire, bolts, etc.)
    (e) Firmware and any related unique support tools (such as 
computers, linkers, editors, test case generators, diagnostic checkers, 
library of functions and system test diagnostics) specifically designed 
for equipment or systems covered under any category of the U.S. 
Munitions List are considered as part of the end-item or component. 
Firmware includes but is not limited to circuits into which software has 
been programmed.
    (f) Software includes but is not limited to the system functional 
design, logic flow, algorithms, application programs, operating systems 
and support software for design, implementation, test, operation, 
diagnosis and repair. A person who intends to export software only 
should, unless it is specifically enumerated in Sec. 121.1 (e.g., 
XIII(b)), apply for a technical data license pursuant to part 125 of 
this subchapter.
    (g) A system is a combination of end-items, components, parts, 
accessories, attachments, firmware or software, specifically designed, 
modified or adapted to operate together to perform a specialized 
military function.
