After processing, the boxes have been put in cold store close to the processing plants or in specialized cold stores of third parties. In case of chilled tuna, the product is brought by refrigerated trucks to local airports and from there to international airports like Sao Paulo and Rio de Janeiro. These airports are well equipped for perishables. Especially air freight of chilled tuna to the United States is very demanded. If in frozen condition, the cold store puts the boxes in the containers and transported to Brazilian main sea ports like Fortaleza in the north, Santos in the middle of Brazil and Itajai in the southern part of the country. Brazil has in total 34 ports, which are governed by the Secretariat of Ports of the Presidency (SEP-PR) of the Ministry of Transport. Of these 34 ports, 16 are governed directly by either state or municipal governments. The other 18 are controlled by joint stock Dock Companies, of which the Federal Government is the major shareholder (The Brazil Business, 2016). From these ports, international shipping companies like Mediterranean Shipping Company (MSC) or Maersk can take the container to every European main port. Companies with a processing plant also tend to have a trading and export department. Companies like the Kowalsky Group, Pesqueira Pionera and Pesqueira Maguary have a long experience of exporting to all parts of the world. There are also quite some smaller trading companies which buy the processed products from bigger and smaller companies and try to export.
