Understanding CNC Machining Shop Certifications: AS9100, ISO 9001, ITAR

Why Certifications Matter

Certifications are not just badges — they represent a supplier's commitment to documented quality systems, regular audits, and continuous improvement. For regulated industries like aerospace, defense, and medical devices, working with a certified CNC machining shop isn't optional — it's a contractual requirement that flows down from OEMs and prime contractors.

AS9100 Certification

AS9100 is the aerospace industry's quality management standard, building on ISO 9001 with additional requirements for product safety, configuration management, and risk management. When evaluating suppliers, verify that their AS9100 certification is current and covers the specific scope of work relevant to your project.

ISO 9001 Certification

ISO 9001 is the international standard for quality management systems, providing a framework for consistent quality, customer satisfaction, and continuous improvement. When evaluating suppliers, verify that their ISO 9001 certification is current and covers the specific scope of work relevant to your project.

ITAR Certification

ITAR is a U.S. government regulation controlling the export of defense-related articles and services. ITAR registration is mandatory for any supplier handling defense-related technical data or manufacturing defense components. When evaluating suppliers, verify that their ITAR certification is current and covers the specific scope of work relevant to your project.

ISO 13485 Certification

ISO 13485 is an important quality standard for CNC machining shops, demonstrating compliance with industry-specific requirements and a commitment to quality processes. When evaluating suppliers, verify that their ISO 13485 certification is current and covers the specific scope of work relevant to your project.

How to Verify Certifications

Always request a copy of the supplier's certificate and check the scope, expiry date, and certifying body. For AS9100, you can verify through the OASIS database. For ISO certifications, check with the accreditation body listed on the certificate. Our directory pre-verifies supplier certifications, but conducting your own verification is a best practice for critical projects.
