Management
• API formed in 1919 as a national trade association
• Standards Program organized in 1923, first standard published in 1924 on drilling
threads
• API now publishes 600+ standards covering all industry segments
• API Standards are:
• Core of Institute’s technical authority
• Represent proven engineering practices and are used in worldwide operations
• Incorporated by State, Federal and International Regulators
• API is accredited by the American National Standards Institute

Drivers for Oil & Gas Industry Supply Chain Standards
• Ongoing industry issues with materials and processes deemed critical to the safety and
reliability of products used in the Oil and Gas industry.
• Increasing global supply chain with limited history with oil and gas standards and
best practices.
• Increasing requirements for local content and sustainable development initiatives including
regulatory compliance.
Goals of Supply Chain Standards
• Institutionalize best practices for supplier review and qualification.
• Harmonize component and process qualification requirements.
• Establish scalable requirements to address various levels of criticality and risk.
• Allow suppliers, product manufacturers and end users access to the industry’s licensing
and accreditation program – the API Monogram Program.
• API 20 Series requirements or being considered as a mandatory by applicable API
product specifications. Below are the specifications that are being considered.
API 6A – 21st edition revision in process
API 6DSS -3rd edition revision in process
API 6D - 25th edition
Using API Supply Chain Standards
• Voluntary licensing and use by the supplier. Example: Casting, Forging and
bolting supplier applies to API for a license for Specification API 20A,or 20B or
20C or 20E or 20F can be approved following audits of their quality management
system API Q1 and of their facility’s compliance with the 20A or 20B or 20C or
20E or 20F requirements.
• Use by the purchaser: Manufacturers may require licensing and/or just
compliance with API Specification 20A, 20B, 20C, 20E or 20F, etc. as a
contractual requirement on material supplied.
• Use by the end-user: May require that manufacturers equipment be
produced from API Specification 20A, 20B, 20C, 20E or 20F, etc. compliant
components.
