Why Supplier Evaluation Fails
Most supplier evaluation failures happen before the order is placed — not after. Buyers skip the documentation step, rely on marketing brochures instead of actual certificates, or assume that a well-designed website correlates with manufacturing quality.
This checklist covers the ten practical checkpoints that procurement professionals use to separate genuine manufacturers from resellers, grey-market operators, and counterfeit-risk suppliers. It is designed for use before your first order with any new supplier — regardless of price point or geographic origin.
The 10-Point Checklist
1. ISO 13485:2016 — Scope, Not Just the Logo
Request the actual ISO 13485:2016 certificate as a PDF — not a logo on a website. When you receive it:
- Confirm the standard version (must be ISO 13485:2016, not an older edition)
- Read the scope statement — this is the critical field. It must explicitly reference your product category. Accept: “Design, development and manufacture of sterile injectable hyaluronic acid dermal fillers.” Reject: “Provision of quality management system documentation services.”
- Note the issuing body (BSI, SGS, TUV, Bureau Veritas, etc.) and verify the certificate number on that body’s online registry
- Check the validity dates — certificates expire and must be renewed
What it tells you: The manufacturer’s quality management system has been independently audited and covers the specific production operations relevant to your purchase.
What it does not tell you: Whether any specific product is CE marked, registered, or approved for use in your market.
2. CE Certificate — Notified Body Number Required
For Class IIb or Class III medical devices (which includes most sterile injectable HA dermal fillers under EU MDR 2017/745 or the previous MDD), CE marking requires review by an EU Notified Body — an independent conformity assessment organisation.
- The four-digit Notified Body number must appear on both the product label and the certificate
- Verify the Notified Body number against the EU NANDO database
- Read the product scope on the certificate — confirm your specific product family is listed
- Check that the certificate covers the correct regulatory directive or regulation (MDD or EU MDR)
A CE mark with no Notified Body number on a sterile injectable is a Class I self-declaration — not valid for sterile injectables. This is one of the most common misrepresentations in grey-market supply.
3. Batch-Specific Certificate of Analysis (CoA)
Request a sample CoA from a recent production lot — not a generic specification sheet. A genuine batch-specific CoA contains:
| Field | What to look for |
|---|---|
| Product name and code | Matches your order specification exactly |
| Batch / lot number | Unique identifier traceable to production records |
| Manufacturing date | Actual date, not a range |
| Expiry date | At least 12 months shelf life remaining |
| Test parameters | Each parameter listed with its specification limit |
| Actual results | Measured values, not just “Complies” or “Pass” |
| Sterility status | Confirmed sterile, with test method referenced |
| Release signature | Dated signature of the Quality Control / QA signatory |
A supplier who cannot produce a batch-specific CoA within 24–48 hours of being asked has either not tested the lot or does not maintain traceable batch records — both are disqualifying.
4. Factory Audit History
Ask whether the manufacturing facility has undergone a third-party audit in the past 24 months and whether the audit summary report is available to qualified buyers. Auditors include: BSI, SGS, Bureau Veritas, TUV SUD, Intertek, and similar.
Note: the Notified Body audit (as part of the CE certification process) counts. ISO 13485 surveillance audits by the certification body also count. A dedicated factory audit by a buyer’s agent is the strongest form of evidence.
5. Sample Policy — Production Stock, Not Lab Batches
Before you commit to a first order, obtain and evaluate samples. When requesting samples, ask:
- Are samples from current production stock or specially prepared lab batches?
- Is a CoA included with the samples?
- What is the sample cost (free, or invoiced against a future order)?
- What quantity is available for evaluation?
Production stock samples are the only reliable proxy for what you will receive in a commercial order. Lab or “pre-production” batches may be prepared with more care than routine production — and will not represent your future delivery quality.
6. MOQ Transparency
Request MOQ figures per SKU and per total order value. Understand:
- Does the MOQ change for private label vs. catalogue product?
- Is the stated MOQ per item, per box, or per shipment?
- What are the options for a first order below MOQ (trial shipment)?
- How does MOQ change with volume — are there price breaks?
A supplier who cannot clearly state MOQ figures (or hedges with “depends on the product”) either doesn’t maintain clear pricing structures or is adjusting terms based on buyer behaviour.
7. Lead Time — Verified Against History
Ask for historical on-time delivery data. Reliable suppliers maintain production schedules documented in their quality management system. Relevant questions:
- What is the typical lead time from order confirmation to shipment?
- What is the breakdown: production time + QC release + export documentation + transit?
- What factors cause lead time to extend?
- What is the on-time delivery rate for the past 12 months?
A supplier who cannot give you a clear lead time breakdown or who hedges with “it depends” for every order type lacks the production planning discipline expected of an ISO 13485-certified operation.
8. Cold Chain and Temperature Documentation
Confirm the supplier’s export packaging capability:
- What packaging configuration is used for temperature-sensitive products?
- For products requiring refrigeration (2–8 °C): are validated cold-chain shippers used?
- Is a temperature log provided for each shipment?
- What is the supplier’s procedure for a temperature excursion during transit?
For most HA dermal fillers (store below 25 °C): confirm the packaging is adequate for your shipping route’s ambient temperature profile — particularly for air freight through hub airports in hot climates.
9. After-Sales and Complaint Handling
Ask how the supplier handles a non-conforming or damaged shipment. A compliant ISO 13485 supplier will have a documented CAPA (Corrective and Preventive Action) procedure. Specifically ask:
- What is the complaint submission process?
- What is the expected response time for a complaint?
- Has the supplier processed any product recalls or Field Safety Corrective Actions (FSCAs) in the past 36 months?
A supplier who cannot articulate their complaint handling process — or who responds that “we deal with issues case by case” — has not implemented the CAPA requirements of ISO 13485. This is disqualifying for regulated medical device supply.
10. Export Authorization and Importer Support
Confirm what export documentation the supplier routinely provides:
- Authorisation letter confirming the exporting supplier’s role
- Certificate of Free Sale (CFS/FSC) where required by your market
- Air transport classification documentation for HA gel (if applicable)
- Assistance with technical documentation for your local regulatory filing
A supplier who has never exported to your market may not understand the documentation requirements — and may be unable to provide critical documents after the fact. Confirm documentation capability before ordering, not after receiving a shipment your customs authority refuses to clear.

What Comes Next
Once a supplier passes this checklist, the next step is placing a trial shipment — ideally at the minimum quantity that allows you to:
- Evaluate the actual delivered product against the samples and CoA
- Test the supplier’s shipping documentation and customs clearance process
- Verify the supplier’s responsiveness to post-delivery queries
A supplier who performs well on a trial shipment — and maintains the same quality on a third and fourth order — is a supplier worth building a long-term relationship with.
Frequently Asked Questions
- What ISO certification is minimum for a dermal filler supplier?
- ISO 13485:2016 with scope text explicitly covering your product category — for example, 'design and manufacture of sterile injectable hyaluronic acid dermal fillers.' A certificate with vague scope (e.g. 'quality management system documentation') does not confirm manufacturing compliance. Verify the certificate number against the issuing body's online registry.
- What should a Certificate of Analysis (CoA) contain?
- A genuine CoA includes: product name and code, batch/lot number, manufacturing date, expiry date, each specification parameter with its limit and the actual measured result, sterility status, and a dated quality release signature. If the document lacks actual test results (showing only 'Complies' or a specification range), it is not a batch-specific CoA.
- How do I know if a CE certificate is genuine?
- Check for the Notified Body number on both the label (e.g. CE 0123) and the certificate document. The four-digit number identifies the independent body that audited the manufacturer. Verify it in the EU NANDO database at ec.europa.eu/growth/tools-databases/nando. A CE mark without a Notified Body number on sterile injectables is a self-declaration only, not a Class IIb/III device approval.
- Is a supplier unwilling to provide samples a red flag?
- Yes. A legitimate manufacturer actively encourages sample evaluation because it reduces post-order disputes and builds confidence. Resistance to providing samples — particularly for first-time buyers — often indicates limited production stock, inability to produce a representative batch, or reluctance to have the product independently evaluated.
- What is the minimum documentation for importing aesthetic medical devices?
- A standard import documentation package includes: commercial invoice with HS code, packing list, Certificate of Origin, ISO 13485 certificate (scoped copy), CE certificate or equivalent market approval, Certificate of Free Sale (for markets requiring one), CoA for the shipment lot, technical specification sheet, and — for HA gel — air transport classification documentation.
