Clearance of coastal goods requires the master to deliver bills on arrival and the proper officer to verify entries before permitting clearance. The vessel master must carry and, on arrival at any customs or coastal port, immediately deliver to the proper officer all bills of coastal goods delivered under section 93 for goods to be unloaded at that port; the proper officer shall permit clearance of unloaded coastal goods only if satisfied they are entered in a bill of coastal goods so delivered.
