Pre-arrival manifest & bill of lading window.
Audit master bills of lading, commercial invoices, and Form M declarations while the vessel is still underway in the Gulf of Guinea.
Audit commercial invoices, packing lists, bills of lading, and ten-digit ECOWAS CET tariff codes before your vessel reaches Apapa or Tin Can Island.
The problem at the port
The packing list says 81,200 kg. The bill of lading says 84,600 kg. And Line 01 is declared under a 10% tariff code instead of the 5% cold-rolled steel subheading. At Apapa or Tin Can Island, that single mismatch triggers a 25% Customs Demand Notice and $250+ per day of terminal demurrage.
