The last step before export is the transport from the factory to the export harbours. Since farming and processing happens in the Mekong Delta, the preferred export harbour is Ho Chi Minh City (HCMC). Transport to HCMC is done by cooler trucks operated by the factories. It is quite common that entire shipments are stored in cold storage facilities in HCMC in order to facilitate final quality inspection, while waiting for authorities to analyze samples and issue all necessary certificates such as Health Certificates (HC) that will accompany the shipment on its way to the buyer destination.
