A Guide for Aerospace Suppliers
The aerospace and defense industry offers tremendous opportunities for small businesses. Whether you make precision parts or ship aerospace components, customers expect proof of quality, security, and compliance.
The same is true if you build software, offer engineering services, or support government contractors.
One of the first questions many companies ask is:
“Which certifications do I actually need?”
The answer depends on your products or services, your customers, and whether you handle controlled information. It also depends on whether you use special manufacturing processes. While not every certification fits every organization, knowing common requirements can help your business win more contracts. It can also build long-term customer confidence.
Here is an overview of the certifications and compliance programs most relevant to small businesses.
They apply to the air, space, and defense supply chain.
ISO 9001 – The Foundation of Quality
For many organizations, ISO 9001 is the starting point.
ISO 9001 is the world’s most recognized Quality Management System (QMS) standard. It helps businesses establish repeatable processes, improve customer satisfaction, reduce errors, and continually improve operations.
For suppliers entering the aerospace or defense market, ISO 9001 often serves as a base. More specialized certifications are built on it.
ISO 9001 is a good fit for:
- Machine shops
- Electronics manufacturers
- Fabricators
- Engineering firms
- Software developers
- Service providers
- Government contractors
- Professional services supporting aerospace companies
Benefits include:
- Improved process consistency
- Better customer satisfaction
- Reduced rework and waste
- Increased operational efficiency
- Stronger competitive advantage
- Easier qualification with larger customers
Many organizations begin with ISO 9001 before advancing to aerospace-specific standards like AS9100.
AS9100 – Quality Management for Aerospace Manufacturers
If your company manufactures products for the aerospace or defense industry, AS9100 Certification is often the certification customers expect.
AS9100 builds upon ISO 9001 by adding aerospace-specific requirements focused on:
- Product safety
- Risk management
- Configuration management
- Counterfeit parts prevention
- Supplier control
- First Article Inspection (FAI)
- Operational planning
- Traceability
Major aerospace manufacturers and defense contractors frequently require AS9100 certification for suppliers producing components used in aircraft, spacecraft, satellites, missiles, and defense systems.
AS9100 is commonly used by:
- Precision machining companies
- Metal fabricators
- Electronics manufacturers
- Composite manufacturers
- Assembly operations
- Aerospace component manufacturers
Achieving AS9100 demonstrates your company’s commitment to meeting the demanding expectations of the aerospace industry.
AS9120 – Designed for Aerospace Distributors
Not every supplier manufactures products.
Companies that purchase, warehouse, and distribute aerospace parts often require AS9120 instead.
AS9120 includes the ISO 9001 requirements while adding controls specifically for distributors, including:
- Product traceability
- Inventory management
- Lot control
- Documentation accuracy
- Prevention of counterfeit parts
- Preservation of product integrity throughout storage and shipping
AS9120 is ideal for:
- Aerospace distributors
- Aviation parts suppliers
- Electronics distributors
- Fastener distributors
- MRO supply companies
- Stocking distributors
If your business supplies certified aerospace products without manufacturing them, AS9120 may be the most appropriate certification.
ITAR Compliance – Protecting Defense Articles
The International Traffic in Arms Regulations (ITAR) are U.S. export control regulations administered by the U.S. Department of State.
Unlike ISO certifications, ITAR is a regulatory compliance requirement, not a certification.
Companies involved with defense articles, technical data, or defense services may be required to register with the Directorate of Defense Trade Controls (DDTC) and implement controls to prevent unauthorized access or export.
ITAR applies to many organizations throughout the defense supply chain, including:
- Manufacturers
- Engineering firms
- Software developers
- Defense contractors
- Electronics companies
- Prototype manufacturers
ITAR compliance often includes:
- Employee access controls
- Visitor controls
- Physical security
- Technical data protection
- Export authorization procedures
- Recordkeeping requirements
- Employee training
Failure to comply can result in significant civil and criminal penalties, making ITAR compliance an important business priority.
CMMC – Cybersecurity for Defense Contractors
Cybersecurity has become one of the fastest-growing requirements in the defense industry.
The Cybersecurity Maturity Model Certification (CMMC) helps ensure contractors adequately protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI).
Organizations performing work for the U.S. Department of Defense may need to comply with CMMC requirements depending on contract language.
CMMC Levels
Depending on the sensitivity of the information you handle, organizations may need to:
- Complete an annual self-assessment
- Undergo an independent third-party assessment
- Maintain ongoing cybersecurity practices
Level 2 organizations typically implement the security requirements found in NIST SP 800-171, which includes 110 security controls covering:
- Access control
- Multi-factor authentication
- Incident response
- Configuration management
- Media protection
- Risk assessment
- Security awareness
- System monitoring
For many small businesses, cybersecurity readiness is now just as important as quality certification when pursuing defense contracts.
NADCAP – Special Process Accreditation
While AS9100 focuses on an organization’s quality management system, NADCAP (National Aerospace and Defense Contractors Accreditation Program) evaluates specific manufacturing processes.
The Performance Review Institute (PRI) administers NADCAP, and the aerospace industry widely recognizes it.
Rather than accrediting an entire company, NADCAP assesses individual special processes that directly affect product quality and safety.
Common NADCAP-accredited processes include:
- Heat treating
- Welding
- Chemical processing
- Coatings
- Non-destructive testing (NDT)
- Composites
- Electronics
- Materials testing
- Measurement and inspection
Many aerospace manufacturers require suppliers performing these special processes to maintain NADCAP accreditation before awarding production work.
Which Certifications Does Your Business Need?
The right combination depends on your role in the supply chain.
Many organizations begin with ISO 9001 and then expand into additional certifications as customer requirements evolve.
Why These Certifications Matter
Large aerospace manufacturers and defense contractors rely on complex global supply chains. Certifications and compliance programs provide confidence that suppliers can consistently deliver quality products while protecting sensitive information and meeting regulatory obligations.
For small businesses, these credentials can help:
- Qualify for more bidding opportunities
- Meet customer and contract requirements
- Reduce operational risk
- Improve efficiency and consistency
- Strengthen cybersecurity
- Increase customer confidence
- Differentiate your business from competitors
- Support long-term business growth
Rather than seeing certification as only a compliance task, many successful suppliers use these systems to build stronger operations. These improvements help both customers and their organization.
