An ECCN (Export Control Classification Number) is a five-character alphanumeric code (e.g., 3A001) used to identify items on the Commerce Control List (CCL). The first character is the category number (0-9), the second is the product group letter (A-E), and the last three digits identify the specific item. ECCNs determine whether an export license is required based on the item, destination country, end use, and end user.

What is the BIS Entity List?

The BIS Entity List (Supplement No. 4 to Part 744 of the EAR) identifies foreign entities — companies, research institutions, government organizations, and individuals — that are subject to specific license requirements for exports, re-exports, or transfers of specified items. Being on the Entity List means a U.S. exporter must obtain a license before shipping most controlled items to that party, and license applications are generally reviewed under a policy of presumption of denial.

Do I need an export license?

Whether you need an export license depends on several factors: the ECCN classification of your item, the destination country, the end use of the item, and the end user. Items classified as EAR99 generally do not require a license except for embargoed destinations or prohibited end users. For items with an ECCN, consult the Commerce Country Chart (EAR Part 738, Supplement 1) to determine license requirements for your specific destination. Always screen the end user against the Consolidated Screening List before shipping.

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.
