(iii) The time of appearance; and
(iv) The name, address, and telephone number of the Customs officer issuing the summons.
(2) Production of records. If a summons issued under this section requires the production of records, the summons shall set forth the information specified in paragraph (b)(1) of this section and shall also describe the records in question with reasonable specificity.
(c) Service of summons - (1) Who may serve. Any Customs officer is authorized to serve a summons issued under this section if designated in the summons to serve it.

Service shall be made upon a domestic or foreign corporation, or upon a partnership or other unincorporated association which is subject to suit under a common name, by delivery to an officer, managing or general agent, or any other agent authorized by appointment or law to receive service of process.
(3) Certificate of service. On the hearing of an application for the enforcement of a summons, the certificate of service signed by the person serving the summons is prima facie evidence of the facts it states.
(d) Transcript of testimony under oath. Testimony of any person taken pursuant to a summons may be taken under oath and when so taken shall be transcribed or otherwise recorded. When testimony is transcribed or otherwise recorded, a copy shall be made available on request to the witness unless for good cause shown the issuing officer determines under 5 U.S.C. 555 that a copy should not be provided. In that event, the witness shall be limited to inspection of the official transcript of the testimony.
