Fair trade is coordinated by a number of organizations that ensure that fair trade principles are respected.  The FLO-I, FairTrade Labelling Organizations International and the IFAT, International Federation of Alternative Trade are the best known of these organizations.
Companies that market and sell fair trade products must be members of or be licensed by one of these organizations. As such, member companies and organizations can display the labels  that certify that the product respects fair trade principles.
