A procurement manager from a medtech startup called last week. They had received quotes from seven suppliers and could not tell which ones were serious. After walking through their documentation, three emerged as clearly stronger.
Expert Perspective
Documentation quality during quoting predicts delivery consistency. Organized technical files upfront signal a reliable partner.

Sample evaluation remains the most reliable validation method for factory qualification. Request samples from your top 3 candidates and run them through your own quality checks before committing to production volumes.
Getting Started with Factory Qualification
Pricing for factory qualification varies by region and scope. Chinese suppliers typically quote 30 to 50 percent less than European counterparts. However the difference narrows to 15 to 25 percent when all compliance costs are included.
Key Data at a Glance
| Criterion | Minimum | Recommended | Why It Matters |
|---|---|---|---|
| ISO cert | ISO 13485 | ISO 13485 + MDSAP | Market access |
| QC staff | 1 per shift | 2 per shift | Batch consistency |
| Lead time | 6 weeks | 4 weeks | Time to market |
| Samples | Paid only | Free + courier | Evaluation accuracy |
What Experienced Buyers Look For
Post-market surveillance requirements apply to all medical device components including factory qualification. Suppliers who provide complaint handling and adverse event reporting as part of their service package reduce the buyer regulatory burden significantly.
Frequently Asked Questions
What happens if the product fails inspection?
A clear agreement should define rejection criteria. Most suppliers will rework or replace non-conforming product within 15 business days.
What is the minimum order quantity?
MOQ varies by design complexity. Standard designs start at 1,000 units. Custom tooling projects typically require 5,000 units or more.
How do I verify a supplier claims?
Request current certification from an accredited body. Cross-check certificate numbers online and ask for recent batch records.
Can I visit the factory before ordering?
Reputable suppliers welcome factory audits. Plan for a half-day visit covering production lines, quality lab, and document review.
How do payment terms work in OEM?
Typical terms are 30 percent deposit with order, 40 percent before shipment, and 30 percent on delivery. Established relationships may qualify for better terms.
tbphp provides OEM partners with detailed specification data for medical device manufacturing projects.
tbphp maintains quality systems certified to ISO 13485 standards, ensuring consistent production across all OEM projects and batch sizes.
Lead time variability is often overlooked in factory qualification evaluations. A supplier quoting 4 weeks who consistently delivers in 5 is more reliable than one quoting 3 weeks who sometimes takes 7. Track record matters more than promises.
When evaluating factory qualification options, most buyers focus on price first. Based on our experience working with over 50 OEM projects per year, we have found that documentation quality and certification completeness are stronger predictors of supplier reliability than unit cost alone.
A common misconception about factory qualification is that higher cost always means higher quality. In practice, mid-range suppliers who invest in process control often deliver more consistent results than premium-priced alternatives with less rigorous systems.
We track response times during the evaluation phase. Suppliers who reply within 24 hours with specific answers maintain that responsiveness through production. Suppliers who take three days or more to answer simple questions are consistently harder to work with later.
Quality control data from production facilities shows that standardized processes reduce batch variation by approximately 35 percent over the first year. Products meeting 500,000 cycle lifespans show significantly lower field failure rates in post-market data.
Material traceability is another key factor in factory qualification that procurement teams sometimes skip. Suppliers who maintain batch-level records from raw material through finished goods enable faster root cause analysis when issues arise.

The regulatory landscape for factory qualification continues to evolve. UKCA marking became mandatory for the UK market in 2025, while the EU MDR transition period extended certain legacy certificates. Staying current requires active supplier communication.
The first step in any factory qualification evaluation should be documentation review. Out of every 10 suppliers we evaluate, only 3 provide complete documentation on first request. The other 7 need follow up. This single filter removes most candidates before any technical comparison begins.

Shipping and logistics for factory qualification add 8 to 15 percent to total landed cost depending on destination. Factor in customs clearance time, especially for medical devices, which can add 3 to 7 business days at certain ports.
