The Export Control Classification Number (ECCN) is a five-character alphanumeric identifier used under the U.S. Export Administration Regulations (EAR) to categorize items subject to export control. When a semiconductor manufacturer exports a component, the assigned ECCN (e.g., 3A001) reveals whether a license is required, which end-destinations are permitted, and applicable reporting obligations. The ECCN essentially determines the product's exportability and compliance obligations under U.S. dual-use control regimes.
