API Composite List


Show More

The API Composite List identifies thousands of organizations around the world that have proven their ability to meet API’s stringent quality and product specifications. Organizations apply for Monogram Licensing to demonstrate to purchasers they can meet the product specifications written by the oil and gas industry, specifically for the oil and gas industry. In addition, API certifies companies complying with API Spec Q1, API Spec Q2, ISO 9001, ISO 14001, OHSAS 18001 and RP 19B (Perforator Design Registration Program).

The API Composite List assists individuals in their search for equipment and services using multiple search criteria. Individuals may search by company name, API product specification, API product, the country where manufacturing occurs, or key words that could be found in the scope of an organization’s business activity.

Bookmark the link. Check it often! Companies achieve certification and join the Composite List weekly. Some, however, are removed from the directory for inability to meet the applicable API specifications or program requirements. You will find other useful information posted here. Simply go to the ‘History’ tab to see a complete listing of Applicants, and Suspended or Cancelled companies, as well as a complete listing of where in the world these qualified organizations are found.

API, through its Monogram Licensing and Management System Registration Certification programs, works diligently to identify qualified suppliers of products and services used in the oil and gas industry. Organizations around the world rely on API’s recognition of these suppliers when making purchasing decisions. When purchasers and users find API licensed or certified suppliers not in conformity with the applicable product or management system standards, API wants to know.

The Nonconformance Reporting website is designed to allow purchasers to file a report for:
  1. suppliers of nonconforming product and services
  2. suppliers that are failing to meet quality management system or other program requirements
