15 C.F.R. § 738.2
(a) Categories. The CCL is divided into 10 categories, numbered as follows:
0—Nuclear Materials, Facilities and Equipment and Miscellaneous 1—Materials, Chemicals, “Microorganisms,” and Toxins 2—Materials Processing 3—Electronics 4—Computers 5—Telecommunications and Information Security 6—Lasers and Sensors 7—Navigation and Avionics 8—Marine 9—Aerospace and Propulsion
(b) Groups. Within each category, items are arranged by group. Each category contains the same five groups. Each Group is identified by the letters A through E, as follows:
A—Equipment, Assemblies and Components B—Test, Inspection and Production Equipment C—Materials D—Software E—Technology
(d) Entries—(1) Composition of an entry. Within each group, individual items are identified by an Export Control Classification Number (ECCN). Each number consists of a set of digits and a letter. The first digit identifies the general category within which the entry falls (e.g., 3A001). The letter immediately following this first digit identifies under which of the five groups the item is listed (e.g., 3A001). The second and third digits differentiate individual entries by identifying the type of controls associated with the items contained in the entry (e.g., 3A001). Table 1 lists the Reasons for Control associated with this second and third digits.
| Last 3 digits of an ECCN | Reason for control |
|---|---|
| 000-099 | National Security (NS). |
| 100-199 | Missile Technology (MT). |
| 200-299 | Nuclear Nonproliferation (NP). |
| 300-399 | Chemical and Biological (CB). |
| 500-599 | Firearms, “Spacecraft,” and related commodities controlled for NS and other reasons. |
| 600-699 | Wassenaar Arrangement Munitions List (WAML) or former U.S. Munitions List (USML) controlled for NS and other reasons. |
| 900-979 | Plurilateral NS and Regional Stability (RS) and other reasons. |
| 980-989 | Crime Control (CC), Short Supply (SS). |
| 990-999 | Anti-terrorism (AT), RS, United Nations Sanctions (UN). |
(2) Reading an ECCN. An ECCN is made up of four sections, the “Heading,” “License Requirements,” “License Exceptions,” and “List of Items Controlled” sections. A brief description of each section and its use follows:
(ii) License Requirements. This section contains a separate line identifying all possible Reasons for Control in order of precedence, and two columns entitled “Control(s)” and “Country Chart”.
(A) The “Controls” header identifies all applicable Reasons for Control, in order of restrictiveness, and to what extent each applies (e.g., to the entire entry or only to certain subparagraphs). Those requiring licenses for a larger number of countries and/or items are listed first. As you read down the list the number of countries and/or items requiring a license declines. Since Reasons for Control are not mutually exclusive, items controlled within a particular ECCN may be controlled for more than one reason. The following is a list of all possible Reasons for Control:
AT Anti-Terrorism CB Chemical & Biological Weapons CC Crime Control CW Chemical Weapons Convention EI Encryption Items FC Firearms Convention MT Missile Technology NS National Security NP Nuclear Nonproliferation RS Regional Stability SS Short Supply UN United Nations Embargo SI Significant Items SL Surreptitious Listening
(C) Items. This paragraph describes the relationship between the “items” paragraph and ECCN headings and will assist your understanding as you classify items on the CCL. When the heading contains the phrase “see List of Items Controlled,” the portion of the heading preceding that phrase is only a summary of the items controlled by the ECCN and the “items” paragraph contains an exclusive list of items described in the heading. Paragraphs (d)(2)(iv)(C)(1), (2) and (3) of this section provide examples of the three different uses of the phrase “(see List of Items Controlled)” in ECCN headings. Each heading on the CCL uses one of these three structures. Understanding the relationship between the heading and the “items” paragraph is important when classifying items that are “subject to the EAR” on the CCL.
(1) “(See List of Items Controlled)” is at the end of the ECCN heading. An example of an ECCN where all of the heading text precedes the phrase “(see List of Items Controlled)” is ECCN 8A002 Marine systems, equipment, “parts” and “components,” as follows (see List of Items Controlled). ECCNs 1A001, 3A001, 6A001, 7A004 and 9A012 are other examples where all of the heading text precedes the phrase “(see List of Items Controlled).” In these types of headings, the items paragraphs must be reviewed to determine whether your item is contained within the heading and classified under that ECCN.
(2) “(See List of Items Controlled)” is in the middle of the ECCN heading. If the phrase “(see List of Items Controlled)” appears in the middle of the ECCN heading, then all portions of the heading that follow the phrase “(see List of Items Controlled)” will list items controlled in addition to the list in the “items” paragraph. An example of such a heading is ECCN 2B992 Non-“numerically controlled” machine tools for generating optical quality surfaces, (see List of Items Controlled) and “specially designed” “parts” and “components” therefor. Under the ECCN 2B992 example, the “items” paragraph must be reviewed to determine whether your item is contained within the first part of the heading (“non-'numerically controlled' machine tools for generating optical quality surfaces”) and classified under 2B992. The second part of the ECCN 2B992 heading (“and 'specially designed' 'parts' and 'components' therefor”) contains the exclusive list described in the heading. ECCNs 1A006, 3B992, 4A001, 6A006 and 7A001 are other examples where the phrase “(see List of Items Controlled)” appears in the middle of the ECCN heading.
(3) ECCNs that do not use the phrase “(see List of Items controlled).” When all items classified in the ECCN are listed in the heading, a sentence is generally included in the “items” paragraph to direct you to the heading. An example of such a heading is ECCN 4E980 “Technology” for the “development,” “production” or “use” of commodities controlled by 4A980. ECCNs 0A982, 5D101, 8D001 and 9A002 are other examples where the heading is the exclusive description of the items classified under those respective ECCNs.
