authorized agent
(2) An authorized agent is a person expressly authorized by a principal to act on his or her behalf. An advance ruling requested by an attorney or other person acting as an agent must include a statement describing the authority under which the request is made. With the exception of attorneys whose authority to represent is known, any person appearing before Customs as an agent in connection with an advance ruling request may be required to present evidence of his or her authority to represent the principal. The foregoing requirements will not apply to an individual representing his or her full-time employer or to a bona-fide officer, director or other qualified representative of a corporation, association, or organized group.
