Goods entered by bill of sight

Where an entry for the landing and examination of goods for delivery on payment of duty is made by bill of sight, such goods shall not be delivered until perfect entry thereof is made and the duties due thereon paid, unless the importer deposits with the Comptroller a sum of money sufficient in amount to cover the estimated duties payable thereon and in addition thereto such sum as the Comptroller may require not being less than the amount deposited as the estimated duties, provided that the Comptroller may, in his discretion, accept a bond in lieu of a cash deposit to secure the additional sum (but not the estimated duties) payable under this section, such bond being conditioned on the making of perfect entry of goods within the specified time and the payment of all duties thereon.
