Declaration where entry imperfect

(1) If the importer of any goods or his known agent makes or subscribes a declaration before the Comptroller or other proper officer that he cannot for want of full information make perfect entry thereof, the Comptroller or other proper officer may receive an entry by bill of sight in such form as the Comptroller may from time to time prescribe for the packages of such goods, by the best description which can be given. (2) Such entry, being signed by the Comptroller or other proper officer, shall be the warrant for provisionally landing such goods to be examined by such importer in the presence of the proper officer, and within three days after the goods are so 27 landed, or within such further time as the Comptroller sees fit after landing thereof, the importer shall make a perfect entry thereof.
