California Code, Business and Professions Code - BPC § 23671

No beer importer shall purchase any beer not manufactured within the state or cause any beer to be transported into the state for sale in the state, unless the out-of-state vendor making shipment of the beer into the state holds a certificate of compliance issued by the department.  A certificate of compliance shall be granted when the out-of-state vendor makes a written agreement with the department to furnish to the board, on or before the 10th day of each month, a report on a form prescribed by the board, showing the quantity of beer shipped by the out-of-state vendor to each licensed beer importer in this state during the preceding month.  The out-of-state vendor shall further agree that it and its agents and all agencies within this state controlled by it will comply with all laws of this state and all rules of the department with respect to the sale of alcoholic beverages, including, but not limited to, Chapter 12 (commencing with Section 25000) of Division 9, and Section 25509, to the same extent as licensees.

If any out-of-state vendor, after obtaining the certificate, fails to submit the report or to comply with Section 14575 of the Public Resources Code, the department may suspend or revoke the certificate of compliance in the manner provided for the suspension or revocation of licenses, and after a hearing which shall be held in the City of Sacramento or in any other county seat in this state which the department determines to be convenient to the holder of the certificate.  No fee shall be charged for the certificate of compliance which shall remain in effect until revoked by the department.
