Each ECCN is a 5-character code: the first digit is the category (0-9), the second character is the product group letter (A-E), and the last three digits identify the specific controlled item within that group.

What is an ECCN?

An Export Control Classification Number (ECCN) is a five-character alphanumeric code used by the U.S. Department of Commerce, Bureau of Industry and Security (BIS) to classify items on the Commerce Control List (CCL). The CCL is found in Supplement No. 1 to Part 774 of the Export Administration Regulations (EAR) and covers a wide range of dual-use goods, software, and technology with both commercial and military applications.

The ECCN structure encodes three pieces of information: the category (digit 0-9, identifying the broad technology area such as electronics, computers, or aerospace), the product group (letter A-E, distinguishing between equipment, test gear, materials, software, and technology), and the item number (three digits identifying the specific controlled item). For example, ECCN 3A001 refers to Category 3 (Electronics), Product Group A (Systems, Equipment & Components), item 001.

Items not specifically listed on the CCL are designated EAR99, meaning they are subject to the EAR but do not require a license for most destinations. However, even EAR99 items may require a license if destined for an embargoed or sanctioned country, a prohibited end user (such as an entity on the BIS Entity List), or a prohibited end use (such as weapons of mass destruction). Exporters should always screen transaction parties against the Consolidated Screening List before shipping.
