American Petroleum Institute

What American Petroleum Institute does

The American Petroleum Institute (API) is the primary U.S. trade association representing all segments of the oil and natural gas industry, founded in 1919 and headquartered in Washington, DC. API represents approximately 600 member companies spanning major integrated oil companies, independent producers, refiners, pipeline operators, and service companies, and is the central standards-setting body for the U.S. industry, having developed over 800 standards covering equipment specifications, safety systems, testing protocols, and operational practices. The organization supports its members and a global licensee base through four interlocking programs: (1) the API Monogram and APIQR certification programs, which license manufacturers and register quality management systems (ISO 9001/14001, API Spec Q1/Q2); (2) the Engine Oil Licensing and Certification System (EOLCS) and Diesel Exhaust Fluid (DEF) certification, which authorize display of the Starburst, Shield, Donut, and DEF marks on licensed products, enforced through the Aftermarket Audit Program; (3) assessment services including Process Safety Site Assessments, Pipeline SMS Assessments, and Pipeline SMS Contractor Assessments aligned with API RP 1173; and (4) Individual Certification Programs (ICP), training, industry events (Inspection and Mechanical Integrity Summit, Offshore Safe Lifting Conference, COS Forum), and the API Composite List directory of certified organizations.

API's revenue model is diversified across five streams: recurring membership dues from approximately 600 corporate members; one-time and perpetual license sales of standards and publications through the API Webstore; certification and licensing fees from Monogram, APIQR, EOLCS, and DEF programs (application fees, annual fees, and audit costs); training and individual certification revenue; and registration and sponsorship income from industry events. API operates from offices in Washington DC, Houston, Beijing, Dubai, and Rio de Janeiro, with a planned India office announced in 2026, and engages in direct federal and state policy advocacy on energy, climate, infrastructure, tax, and trade issues. The organization is governed by its members and operates as a non-profit under the laws of the District of Columbia, with no public technology API or software product offering; rather, it provides standards, certifications, assessments, and industry guidance.
