Why Proper Contract Manufacturer Vetting Matters
Choosing the wrong contract manufacturer can result in:
- Product quality issues and customer complaints

- Delayed launches and missed market opportunities
- Hidden costs and budget overruns
- Damaged brand reputation
A thorough vetting process protects your investment and ensures your products meet the highest standards of quality and safety.
Essential Questions to Ask Contract Manufacturers
Do They Actually Manufacture In-House?
Why This Matters:
Many companies pose as manufacturers while simply acting as middlemen, outsourcing your work to third parties. This creates quality control issues and removes your oversight of the manufacturing process.
Questions to Ask:
- “Can you provide a tour of your manufacturing facilities?”
- “What specific equipment do you own and operate?”
- “Who will be directly responsible for manufacturing my products?”
Red Flag:
If they hesitate to offer a facility tour or provide vague answers about their equipment, they may be a broker rather than a true manufacturer.
What Certifications and Compliance Standards Do They Hold?
Stringent Production Requirements:
- FDA Registration and Inspection Status – Ensures compliance with federal regulations
- USDA Organic Certification – Required for organic product claims
- GMP (Good Manufacturing Practices) – Industry standard for quality systems
- NSF International Certification – Third-party quality verification
- ISO Certifications – International quality management standards
Questions to Ask:
- “Can you provide copies of all current certifications?”
- “When was your last FDA inspection, and what were the results?”
- “How do you maintain compliance with changing regulations?”
Can You Tour Their Manufacturing Facilities?
Why Facility Tours Are Essential:
- Verify they actually manufacture products on-site
- Assess cleanliness and organization standards
- Meet the team who will handle your products
- Evaluate equipment quality and capabilities
- Observe quality control procedures in action
What to Look For During Tours:
- Clean, well-organized production areas
- Modern, well-maintained equipment
- Proper safety protocols and procedures
- Qualified, knowledgeable staff
- Robust quality control systems
How Responsive Are They to Communication?
Warning Signs of Poor Communication:
- Difficulty reaching live representatives
- Delayed responses to emails and calls
- Always being redirected to voicemail or receptionists
- Vague or incomplete answers to technical questions
What Good Communication Looks Like:
- Prompt responses within 24-48 hours
- Direct access to project managers and technical staff
- Proactive updates on project status
- Clear, detailed explanations of processes and timelines
Can They Provide Customer References?
Why References Matter:
Established manufacturers should be proud of their work and willing to connect you with satisfied customers who can share honest feedback about their experience.
Questions to Ask References:
- “How was the overall experience working with this manufacturer?”
- “Did they meet promised timelines and quality standards?”
- “How did they handle any issues or challenges that arose?”
- “Would you recommend them and work with them again?”
Do They Carry Product Liability Insurance?
Critical Insurance Requirements:
- Product liability insurance with adequate coverage limits
- Insurance policy should name the manufacturer specifically
- Coverage should extend to your products and brand
Why This Matters:
Without proper insurance coverage, you have no protection if manufacturing defects lead to product liability claims.
Red Flags to Avoid
Business Verification Red Flags
- Short Business History: Companies in business less than 3-5 years may lack experience handling complex challenges
- No Online Presence: Legitimate manufacturers maintain professional websites and online reviews
- Poor Online Reviews: While no company is perfect, consistently negative reviews indicate systemic problems
- Unlicensed Operations: Always verify business licenses and registrations
Operational Red Flags
- Reluctance to Provide Tours: Legitimate manufacturers welcome facility visits
- Vague Responses: Inability to provide specific details about processes and capabilities
- No Quality Documentation: Lack of quality manuals, SOPs, or testing protocols
- Unrealistic Promises: Extremely low prices or impossibly fast timelines often indicate corners being cut
