Export Controls & Sanctions
Export Control Classification Number
Also known as: ECCN
An Export Control Classification Number is a five-character alphanumeric code that identifies a commercial item's category and the specific reasons it is controlled under the export regulations, such as national security, chemical or biological weapons concerns, or anti-terrorism. The ECCN, read together with the country of destination and a control chart, tells an exporter whether a license is required for a particular shipment. Items that are subject to the regulations but not listed under a specific ECCN fall into a residual catch-all designation, which still requires screening against embargoes and prohibited end uses.
The export equivalent of an HTS code, and the same discipline applies: the supplier's assertion is a starting point, not an answer. "EAR99" is a conclusion that has to be reached, and it is asserted far more often than it is established.
Where it matters for compliance
- The exporter is responsible for the classification, whoever supplied it.
- EAR99 is a residual category, not a default and not an exemption.
