An importer's job used to end at the Chittagong port: clear the container, handle paperwork, warehouse it, sell into the wholesale market at that week's price. Distribution was someone else's problem - aratdars, traders, resellers - each taking a margin while the importer kept what was left.
That model has failed for years. Wholesale prices on imported produce swing 20 percent in a week, and the cold chain breaks once the container leaves the port. Apples from Washington or onions from India pass through four hands, three temperature zones, and two weeks of transit before reaching a shelf. Quality variance kills margin; spoilage kills volume. The importer carries the risk from LC to landing, then hands the chain to traders they cannot see into.
The import side of this trade is not the problem. The distribution side is.
