The Commerce Control List (CCL) is a list of items under the export control jurisdiction of the Bureau of Industry and Security, U.S. Department of Commerce. It is organized into ten broad categories reflecting the nature of the products, such as electronics or nuclear materials and is further divided into five product groups encompassing software and technologies.
These categories and product groups ultimately create a five-character alphanumeric code (e.g. 4D001) known as an Export Control Classification Number (ECCN).
The CCL list is structured as follows:
