27 C.F.R. § 40.133
The amount of the bond of a manufacturer of tobacco products shall be not less than the total amount of tax liability on all tobacco products manufactured in his factory, received in bond from other factories and from export warehouses, and released to him in bond from customs custody, during any calendar month. Where the amount of any bond is no longer sufficient and the bond is in less than the maximum amount, the manufacturer shall immediately file a strengthening or superseding bond as required by this subpart. The amount of any such bond (or the total amount including strengthening bonds, if any) need not exceed $250,000 for a manufacturer producing or receiving cigarettes in bond; need not exceed $150,000 for a manufacturer producing or receiving cigars, smokeless tobacco, pipe tobacco, or roll-your-own tobacco in bond; and need not exceed $250,000 for a manufacturer producing or receiving any combination of tobacco products in bond. The bond of a manufacturer of tobacco products shall in no case be less than $1,000.
