(a) Surety bonds required under the provisions of this subpart may be given only with corporate sureties holding certificates of authority from the Secretary of the Treasury as acceptable sureties on Federal bonds. Limitations concerning corporate sureties are prescribed by the Secretary in the current revision of the Treasury Department Circular 570, Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies, as revised (see paragraph (c) of this section). The surety shall have no interest whatever in the business covered by the bond.

(b) Each bond and each extension of coverage of bond shall at the time of filing be accompanied by a power of attorney authorizing the agent or officer who executed the bond to so act on behalf of the surety. The appropriate TTB officer who is authorized to approve the bond may, whenever he or she deems it necessary, require additional evidence of the authority of the agent or officer to execute the bond or extension of coverage of bond. The power of attorney shall be prepared on a form provided by the surety company and executed under the corporate seal of the company. If the power of attorney submitted is other than a manually signed document, it shall be accompanied by a certificate of its validity.

(c) Treasury Department Circular 570 is published in the Federal Register annually on the first business day in July, and supplemental changes are published periodically thereafter (see https://www.federalregister.gov). The most recent circular and any supplemental changes to it may be viewed on the Bureau of the Fiscal Service website (see https://fiscal.treasury.gov).
