This is where the export documentation comes into play. The documentation relates to the documentation required by both the export authorities in South Africa and by the importer and importing authorities. Once again, the L/C will spell out what documents are required. Some countries require certificates of origin to be issued by the local chamber of commerce and export permits may even be required for selected products. Your freight forwarder should be able to assist you with (a) obtaining these documents, and (b) with completing them.
