Every employer who has secured the payment of compensation as required by 33 U.S.C. 932 and by the regulations in this part may request a certificate from the district director in the compensation district in which he has operations, and for which a certificate is required by 33 U.S.C. 937,showing. Only one such certificate will be issued to an employer in a compensation district, and it will be valid only during the period for which such employer has secured such payment. An employer so desiring may have photocopies of such a certificate made for use in different places within the compensation district. Two forms of such certificates have been provided by the Office, one form for use where the employer has obtained insurance generally under these regulations, and one for use where the employer has been authorized as a self-insurer.

Upon the termination by expiration, cancellation or otherwise, of a policy of insurance issued under the provisions of law and these regulations, or the revocation or termination of the privilege of self-insurance granted by the Office, all certificates of compliance issued on the basis of such insurance or self-insurance shall be void and shall be returned by the employer to the district director issuing them with a statement of the reason for such return. An employer holding certificate of compliance under an insurance policy which has expired, pending renewal of such insurance need not return such certificate of compliance if such expired insurance is promptly replaced. An employer who has secured renewal of insurance upon the expiration of policy under said Act or whose self-insurance thereunder is reauthorized without a break in the continuity thereof need not return an expired certificate of compliance.
