# §120.10. Introduction to the U.S. Munitions List.

- (a) **The U.S. Munitions List.** The articles, services, and related technical data designated as defense articles or defense services pursuant to sections 38 and 47(7) of the Arms Export Control Act appear in [part 121](/cfr/22/part121.md) of this subchapter and constitute the U.S. Munitions List (USML). Changes in designations are published in the Federal Register. [Paragraphs (b) through (d)](#b..d) of this section describe or explain the elements of a USML category.
- (b) **Composition of U.S. Munitions List categories.** USML categories are organized by paragraphs and subparagraphs identified alphanumerically. They usually start by enumerating or otherwise describing end-items, followed by major systems and equipment; parts, components, accessories, and attachments; and technical data and defense services directly related to the defense articles of that USML category.
- (c) **Significant Military Equipment paragraphs in the USML.** All items described within a USML paragraph or subordinate paragraph that is preceded by an asterisk (*) are designated Significant Military Equipment (SME). Note that technical data directly related to the manufacture or production of a defense article designated as SME is also designated as SME.
- (d) **Missile Technology Control Regime (MTCR) designation.** Annotation with the parenthetical (MT) at the end of a USML entry indicates those defense articles that are on the MTCR Annex.
