Each vessel of the United States to which the Safety Convention applies shall comply with the radio and communication provisions of said Convention at all times while the vessel is in use, in addition to all other requirements of law, and shall have on board an appropriate certificate as prescribed by the Safety Convention.

Appropriate certificates concerning the radio particulars provided for in said Convention shall be issued upon proper request to any vessel which is subject to the radio provisions of the Safety Convention and is found by the Commission to comply therewith. Cargo ship safety radio telegraphy certificates, cargo ship safety radiotelephony certificates, and exemption certificates with respect to radio particulars shall be issued by the Commission. Other certificates concerning the radio particulars provided for in the said Convention shall be issued by the Commandant of the Coast Guard or whatever other agency is authorized by law to do so upon request of the Commission made after proper inspection or determination of the facts. If the holder of a certificate violates the radio provisions of the Safety Convention or the provisions of this chapter, or the rules, regulations, or conditions prescribed by the Commission, and if the effective administration of the Safety Convention or of this part so requires, the Commission, after hearing in accordance with law, is authorized to modify or cancel a certificate which it has issued, or to request the modification or cancellation of a certificate which has been issued by another agency upon the Commission’s request. Upon receipt of such request for modification or cancellation, the Commandant of the Coast Guard, or whatever agency is authorized by law to do so, shall modify or cancel the certificate in accordance therewith.
