At Douala, storage and demurrage costs add up quickly if release is delayed, so line up your broker, payments and transport before the vessel arrives rather than starting the process once it has already docked. Road transport from the port to Yaounde and the rest of the country should be booked in advance, especially during periods of port congestion. Confirm the current legal retention period for import records with Cameroon Customs and the tax authority, since specific retention periods are set in national regulation and can change.
