abstract:An Export Control Classification Number (ECCN) is a specific alpha-numeric code that identifies the level of export control for articles, technology and software (collectively, "Items") that are exported from member states of the Wassenaar Arrangement, including the United States. The ECCN classification that applies to any specific item is determined by referring to a table that is issued for the United States by the Bureau of Industry and Security and for Europe by Regulation 428/2009.
