How does it differ from bill of entry?

Bill of lading is issued by the shipping company after the receipt of freight, it serves as an
evidence that the shipping company has accepted the goods for carrying to the designated destination. In case the goods are being sent by air, this document is referred to as airway bill.
On the other hand ‘Bill of entry’ is filled by the importer for assessment of customs import duty.
One appraise examines the document carefully and gives the examination order. The importer procures the said document prepared by the appraiser and pays the duty, if any. After payment of the import duty, the bill of entry has to be presented to the dock superintendent. The examiner gives his report on the hill of entry which is then presented to the port authority which issues the release order after receiving necessary charges.
