All existing authorities to purchase products in insurrectionary States are hereby revoked; except that products purchased in good faith under such authorities, and paid for, in whole or in part, prior to the 29th. day of July 1864, may be transported to market as before the passage of the Act of July 2. 1864, subject to the following limitations and conditions; and included in the following classes:
