Authority of TTB officers to enter premises.
The appropriate TTB officer may enter in the daytime any premises where cigarette papers and tubes are produced or kept, so far as it may be necessary for the purpose of examining such articles. When such premises are open at night, the appropriate TTB officer may enter them, while so open, in the performance of his or her official duties. The owner of such premises, or person having the superintendence of the same, who refuses to admit the appropriate TTB officer or permit the appropriate TTB officer to examine such cigarette papers and tubes shall be liable to the penalties prescribed by law for the offense.
