Meeting a contract manufacturer for the first time is a major step for any medical device company. That first discussion shapes expectations, clarifies risk, and helps determine whether you have found a manufacturing partner you can trust with quality, timelines, and regulatory compliance.
This guide provides questions to ask contract manufacturers across quality, production, materials, supply chain, and pricing. You can treat it as a checklist of interview questions to ask.
1. Start with Objectives and Product Scope
Before discussing processes or costs, both teams must understand the medical device, market space, and key goals.
Key questions to ask manufacturers here:
- What experience do you have with products similar to ours?
- Do you have examples involving packaging, assembly, and/or sterilization?
- Which applications, materials, and regulatory pathways are part of that experience?
Listen for references to:
- ISO certification
- internal audits
- experience
- close visibility into production quality standards.
Manufacturers with knowledge of similar devices can move faster and anticipate potential issues earlier in the production process. This matters in a sector where thousands of medical device recalls are logged each year in FDA records, many linked to issues that better upstream insight could have prevented.
2. Quality, Compliance, and Industry Certifications
Next, shift the conversation toward how the manufacturer thinks about quality and compliance on a daily basis. For medical devices, this goes beyond a certificate on the wall. You want to understand whether their systems can consistently support your production quality standards and regulatory commitments.
Quality and compliance questions to ask a contract manufacturer:
- What quality systems do you maintain?
- Can you share details about third-party certifications and industry certifications?
- How often are internal audits performed?
- How do you handle non-conformances and corrective actions?
A reliable manufacturer will reference:
- ISO 13485
- state-of-the-art technology
- production line controls
- experienced operators
- research and investigations when deviations occur.
Request examples of how they have supported regulatory submissions, customer and FDA audits, or sterilization validations.
3. Facilities, Technology, and Production Capacity
Once you understand quality systems, the next step is to confirm whether the contract manufacturer can actually produce the quantity, formats, and timelines that your product requires. Capacity is not just about space on the floor — it’s about staffing, scheduling, tooling, and uninterrupted access to components.
Capability-focused questions to ask manufacturers:
- What is your production capacity today, and how does it scale during growth?
- What equipment is dedicated to packaging, assembly, and sterilization?
- Do you invest in technology to improve speed and consistency?
- What does the production line look like during peak periods?
- Can you increase staffing or shifts during high demand?
Ask to see the manufacturing facility whenever possible. Even a remote tour provides insight into organization, cleanliness, labeling, segregation of materials, and safety practices. A strong facility will also have a clear plan for:
- cleanroom control
- preventive maintenance
- validated equipment
- documented tooling and fixture management.
Given that supply-chain instability ranks as a top concern for a large majority of business leaders in recent surveys, it is worth probing how the plant maintains throughput when suppliers, staffing, or logistics are under pressure.
4. Materials, Sustainability, and Sourcing Suppliers
After capacity and equipment, your next topic is materials. The way a manufacturer handles materials sourcing, sustainability, and sourcing suppliers directly affects risk, reputation, and long-term costs.
Materials and sourcing questions to ask a contract manufacturer:
- How do you manage sourcing and 3rd party suppliers?
- What happens if supply disruptions occur?
- Do you offer custom packaging solutions, including custom corrugated boxes?
- How do you track traceability for each lot?
The right partner should be prepared to discuss availability, testing, and compatibility with sterilization methods. For many medical device companies, packaging is a major part of risk management. Poor packaging can compromise sterility, increase shipping costs, or create complaints. The best manufacturers will have experience across multiple material formats and can recommend the right match to protect your device.
5. Lead Times, Timelines, and Scheduling
Time is one of the strongest drivers of project success. Early discussions must clarify how long things take and why.
Questions to ask a contract manufacturer:
- What is the expected lead time for tooling, materials, and sample development?
- What is the minimum order quantity or minimum order requirement for production?
- How do you communicate delays?
- What does the typical production timeline look like from PO to shipment?
- Which variables most often affect lead times?
Clear communication around scheduling is essential. Good manufacturers do not hide delays — they explain them early, offer alternatives, and adjust the plan.
This is especially helpful during sterilization validation, packaging qualification, and scale-up stages, where timelines are influenced by regulatory obligations and production testing.
6. Cost, Payment Terms, and Total Delivered Pricing
Cost discussions should include more than the unit price. A transparent partner will clearly explain how they estimate costs, including labor, materials, tooling, validation, and freight.
Questions to ask:
- How do you create a Cost Breakdown or quote?
- What payment terms do you require?
- Do you request full payment before release, or do you invoice at milestones?
- How do shipping rates and shipping costs factor into the total price?
- Are fees for sample development separate?
Understanding how cost estimation works helps you compare suppliers accurately. Two quotes can appear similar, yet one may exclude packaging, testing, or labeling. A complete quote removes surprises and builds trust.
7. IP Protection, Confidentiality, and Business Continuity
As you deepen collaboration, intellectual property and data security become central. Many companies also explore private labeling or shared brands.
IP and program-structure questions to ask manufacturers:
Questions to include during early meetings:
- How do you secure and store confidential files?
- What agreements are needed before sharing specifications?
- How do you handle business continuity?
- What happens to our tooling or molds if ownership changes?
A quality-focused partner should discuss backup processes, controlled access, and what happens during staffing transitions. Reliable companies take continuity seriously — especially where regulated product quality and safety are at stake.
8. Customer Service and Communication
Consistent communication protects lead times, quality, and expectations. This applies during qualification, mass production, and post-launch support.
Questions to ask:
- Who is my main point of contact?
- How are changes documented?
- How often will we review production status?
- Do you schedule regular customer calls?
Clear communication is a strong predictor of long-term business relationships. When issues arise — and they will — you want a partner who responds quickly, documents decisions, and supports investigations.
9. Long-Term Business Relationships and Succession Planning
A contract manufacturer is not just a production vendor. They often become part of the operational fabric of your company. Over time, they influence product availability, packaging choices, manufacturing schedules, and overall risk management. This is why discussions around stability and leadership matter during your first conversations.
Questions to ask a contract manufacturer:
- Who are the operational leaders responsible for production and quality?
- How long have they been with the company?
- Do you have a documented succession plan for key roles?
- How do you handle knowledge transfer when people retire or shift into new functions?
- What kind of cross-training occurs on the production floor?
Leadership continuity prevents gaps in scheduling, documentation, approval cycles, and chain-of-custody. When a critical position changes—such as a quality manager or master scheduler—you want confidence that production remains consistent, and that validated processes are not reinvented.
Survey work with supply chain leaders consistently shows that leadership turnover and weak development pipelines are now viewed as major threats to resilience, so asking about succession and cross-training is not just a formality—it’s risk mitigation.
Long-term relationships are built on consistency. Pay attention to tenure, turnover, and cultural alignment between your teams. The best partners think about stability the same way you do: they protect it.
10. Special Considerations for Packaging, Sterilization, and Medical Devices
Medical devices introduce requirements that go far beyond boxing and palletizing. Packaging and sterilization are part of the regulatory submission, not just a purchasing decision. A contract manufacturer that works with medical devices should be able to discuss:
- testing methods
- packaging validations
- sterility assurance
- labeling and traceability
Targeted questions to ask a contract manufacturer in this space:
- What packaging formats do you support (pouches, trays, custom designs, barrier systems)?
- Do you partner with 3rd party suppliers for sterilization, or is it managed in-house?
- What is your experience with EO, gamma, or other sterilization modalities?
- How do you validate packaging integrity over time and after shipment?
- Can you provide guidance on shipping configurations to reduce damage and complaints?
The right partner can help balance these goals without compromising safety or regulatory expectations.
Evaluating Fit
After your first meeting, review the notes with your internal stakeholders. Key indicators of fit include:
- Clear documentation and follow-up
- Alignment with production process and regulatory requirements
- Confidence in their manufacturing industry experience
- Respect for your Intellectual Property and security standards
- Openness to collaboration on private label program or branding
- Ability to support mixed material formats, including metal components and plastic components.
A decision is rarely based on one factor. Fit is often a combination of technical ability, responsiveness, experience, and long-term stability.
Next Steps for Your Selection Process
After gathering answers, compare manufacturers using the same criteria:
- Quality and compliance strength
- Experience with similar products
- Pricing transparency
- Ability to scale
- Communication and customer service.
A manufacturer that aligns with your expectations on all these fronts is far more likely to deliver consistent outcomes over time.
Your next meeting will move beyond introductions and into planning:
- Production schedule
- Documentation transfer
- Tooling and samples
- Packaging decisions
- Freight quotes
- Validation timelines.
This is the start of a working relationship that supports your program across packaging, assembly, and sterilization — and helps protect patient wellbeing through every shipment.
