During the period 2012-2013 almost 5,000 tons of natural stone products were imported for a client in the civil engineering sector. Clear agreements about the required quality and tolerances were made with the Chinese factory. Local presence of GTO through Fourwins (American owned) made regular monitoring of the production process possible, so that agreements were strictly followed up. As a result, all products were available in the Netherlands according to the agreed schedule and the project was completed according to planning.

GTO inspected the local quarry for required quality and reliability, provided the contracting, supervised the production process in accordance with international standards and safety (eg. no child labor) and organized the entire import process.
