Reefer container shortage hits frozen food exports from Bangladesh to Europe and the United States, causing concerns over rising freight costs and delayed shipments. The shortage is due to factors such as port authority delays, conversion of containers for RMG exports, and regional restrictions. The lack of available containers has led to a backlog, with some containers being converted into non-refrigerated ones. Importers are urged to clear their goods promptly to avoid auction of containers or face delays in shipping.
