Composite List

Show More

The API Composite List  is an online Directory of API Monogram Licensees and Management System Registered Organizations. It's the easiest way to find real-time information about those companies and their current registration / licensee status. Search by company name, certificate number, product type, key words in the registration scope, status, and more.

The companies found in the API Composite List represent the foremost equipment manufacturers

and service supply organizations in the industry. They are:

  • API Monogram® Licensees
  • API Spec Q1® Registered Manufacturing Organizations
  • API Spec Q2™ Registered Service Organizations
  • API 18LCM Registered Organizations
  • ISO 9001 Registered Organizations
  • ISO 14001 Registered Organizations
  • OHSAS 18001 Registered Organizations

The active companies found in the API Composite List have proven their ability to meet stringent quality, product, or service specifications. Some companies even hold multiple registrations or licenses.

Upon the successful completion of an on-site audit of the facility’s quality management system and product designs to the requirements of API Spec. Q1 and the relevant API product specifications, the listed facility is granted a license to apply the API Monogram registered mark to listed types of equipment that meets the product specification requirements. Each API monogram license is facility-specific and requires an initial on-site audit by specially-trained API auditors before licensing and every year thereafter. If the facility also holds a management system registration through APIQR, they are audited annually. In addition to scheduled audits, API also reserves the right to conduct unscheduled audits as they deem appropriate.

Organizations can apply to have their API Spec Q1, API Spec Q2, ISO 9001, ISO 14001, or OHSAS 18001 management system registered by APIQR (an ANAB-accredited certification body) after their initial on-site audit and maintain their management system registrations by annual on-site audits thereafter. These companies are also subject to unscheduled audits.

They are the finest companies and facilities in the world, and now you know who they are and how to find them.

The API Composite List is also where you will find companies that hold Registered Designs for API 19B Perforating Equipment.

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
