CCATS and ERN
The Commodity Classification Automated Tracking System number (CCATS) is registration number assigned to items whose classification against the Commerce Control List (CCL) was established by a BIS review under the EAR.
Microsoft provides the CCATS number for its products when applicable so that exporters may use it for their export operations as required.
As the producer of software commodity products filing encryption registrations, self-classification reports or commodity classification for its products with BIS, Microsoft has been assigned an Encryption Registration Number (ERN).
Microsoft’s ERN is R100177.
