As a petroleum machinery certification authority approved by U.S. Department of Commerce and Federal Trade Commission, API enjoys a high reputation both in America and in other countries around the world. Its technical standards on petrochemical industry and production machinery are widely used by a number of countries. Generally, products with API marks are required by many oil companies in the Middle East, South America and Asia to be qualified for their bidding to purchase petroleum machinery. Therefore, petroleum machinery and equipment with API marks are identified as reliable in quality and as advanced in technology.
