The Administrator shall issue a Certificate of Registration (DEA Form 223) to an applicant if the issuance of registration or reregistration is required under the applicable provisions of sections 303 or 1008 of the Act (21 U.S.C. 823 and 958).

Any person entitled to file comments or objections to the issuance of the proposed registration pursuant to § 1301.33(a) may participate in the hearing by filing notice of appearance in accordance with § 1301.43. Such persons shall have 30 days to file a notice of appearance after the date of publication of the notice of a request for a hearing in the Federal Register.
