A customs issue due to over shipment in Nigeria occurs when the quantity of goods imported is higher than what was declared in the customs documents such as the Single Goods Declaration (SGD), invoice, packing list, or bill of lading. This mismatch can trigger inspection, delays, penalties, or even seizure at ports like Apapa, Tin Can Island, and Lekki Deep Sea Port.
In simple terms, it means you brought in more goods than what customs was officially told.
What Triggers Customs Issues in Over Shipment Cases
Customs becomes concerned when there is a mismatch between:
- Declared quantity vs physical cargo
