What does the second character of each Export Control Classification Number (ECCN) specify?

The second character of each Export Control Classification Number (ECCN) serves as the Group indicator, which categorizes the product based on its functionality or application. The ECCNs are part of the Commerce Control List (CCL) used in export licensing and compliance. Each ECCN is structured with a specific format where the second character defines the particular category or "Group" of the commodity, technology, or software being classified. This classification is critical for determining the applicable export licensing requirements and restrictions.

The Group indicator helps exporters and regulatory agencies quickly identify the nature of the item, allowing for efficient management of export compliance and adherence to relevant regulations. Understanding ECCNs and their components is essential in the export process to ensure that goods are properly classified and controlled according to U.S. export regulations.
