Customs control kinds

The ECCN is the Export Control Classification Number. This code represents the classification of an item in the EAR Commerce Control List (CCL) which identifies the items that are controlled by the EAR. The five-digit alpha-numeric designation represents the Category (numeric), Product Group (alphabetic), and Type of Control (numeric). An example would be 9A991, identifying the Aerospace category, the End-Item product group (A), and the Anti-Terrorism / Crime Control / Regional Stability reason for control .
