Of those exports and reexports subject to the Export Administration Regulations (EAR), a relatively small percentage require the submission of a license application to the Department of Commerce. License requirements are dependent upon an item's technical characteristics, the destination, the end-use, and the end-user, and other activities of the end-user. You will need the following five facts to determine your obligations under the EAR: What is the item you intend to export or reexport; Where is it going; Who will receive it; What will they do with it; and, What other activities are they involved in?
The first step in determining your license requirements under the EAR is to classify your product by determining its Export Control Classification Number (ECCN) on the Commerce Control List (CCL). More information on Commodity Classifications.
For assistance in determining which U.S. Government agency has licensing jurisdiction over your export see Commodity Jurisdictions.
