The quality management standard the oil and gas industry requires from every equipment manufacturer and service provider in its supply chain.
API Q1 (manufacturing) and API Q2 (service supply organisations) are the American Petroleum Institute's quality management system specifications for the petroleum and natural gas industry. Required by major NOCs and IOCs worldwide, they are built on ISO 9001 with industry-specific additions.

- Risk management and contingency planningImplement the systematic risk identification and contingency planning processes that petroleum industry clients require from their supply chain.
- Product realization and service delivery controlsEstablish the design controls, work instruction systems, and verification processes specific to petroleum equipment manufacturing or service delivery.
- Management of changeBuild formal management of change processes for product design, manufacturing processes, and key personnel — a specific API requirement.
- Preventive and corrective action (PACA)Implement the root cause analysis and preventive action requirements that API specifications demand beyond standard ISO 9001 corrective action.
The business case
Saudi Aramco, ADNOC, and every major oil company require API Q1 or Q2 certification from equipment manufacturers and service providers. Without it, you are not on the approved vendor list.
API certification is recognised globally as the oil and gas industry's quality management benchmark — enabling access to projects and customers worldwide.
API certification signals that your quality system addresses the specific risks, product criticality, and performance requirements of petroleum applications.
API certification reduces the frequency of client-led supplier audits — because major operators trust API certification as a credible proxy for their own assessment.
