Finding and vetting new suppliers for raw materials requires a structured, multi-step approach to mitigate supply chain risks, control costs, and ensure consistent quality.
Here is the best way to handle the end-to-end process:
Phase 1: Sourcing and Finding Suppliers
Phase 2: Initial Screening (RFI / Pre-Qualification)
Phase 3: Deep Vetting and Risk Assessment (RFQ & Audits)
Phase 4: Contracting and Onboarding
If you'd like, let me know:
I can provide tailored vetting criteria or a custom audit checklist template.
The best approach is to treat supplier sourcing as a **funnel: discover broadly, qualify quickly, then validate deeply before awarding business**. For raw materials, I’d use a structured supplier-qualification process rather than relying pr
The best approach is to treat supplier sourcing as a funnel: discover broadly, qualify quickly, then validate deeply before awarding business. For raw materials, I’d use a structured supplier-qualification process rather than relying primarily on price or a supplier’s sales pitch.
Create a one-page supplier specification covering:
This prevents you from comparing suppliers on price when they're actually offering different products.
Use several channels rather than one:
I'd initially target 8–15 candidates, then narrow that to roughly 3–5 serious contenders.
Send every candidate the same RFQ and supplier questionnaire.
Ask for:
Company
Financial/commercial
Quality
ISO 9001 can be a useful quality-system indicator, but certification shouldn't automatically make a supplier "approved." ISO itself notes that certification is voluntary and that certification by an independent/accredited body provides additional confidence.
This is where supplier vetting gets much better.
Don't simply accept a questionnaire saying "ISO certified" or "we have excellent quality."
Verify:
CIPS specifically recommends supplier onboarding and due diligence to reduce financial, regulatory and reputational risk, rather than relying solely on supplier self-reporting.
I'd use a weighted scorecard such as:
| Category | Weight |
|---|---|
| Quality & technical capability | 25% |
| Total landed cost | 20% |
| Capacity & scalability | 15% |
| Delivery/reliability | 15% |
| Financial/business stability | 10% |
| Compliance/ESG | 10% |
| Communication/service | 5% |
For critical raw materials, increase the weights for quality, continuity and risk—and decrease the emphasis on unit price.
Also distinguish between must-pass criteria and scored criteria. For example, a supplier that cannot meet your material specification should fail regardless of how cheap it is.
For the finalists, don't go directly from RFQ to PO.
Use:
Sample → laboratory/production trial → technical approval → supplier audit → commercial negotiation → controlled first order
For critical materials, perform an on-site audit covering:
ISO guidance specifically recognizes supplier evaluation, verification of externally provided products/services, and maintaining an approved-provider process as part of effective control.
Your sourcing model should calculate:
Total landed cost = unit price + freight + duties + inspection/testing + tooling + inventory + quality failures + expected disruption cost
A supplier that's 4% cheaper but has twice the lead time and significantly higher defect rates may be dramatically more expensive.
Before awarding significant volume, ask:
For strategic suppliers, consider qualifying a second source before you actually need one. Procurement organizations are increasingly using centralized supplier assessments and data to improve resilience and scale due diligence.
Don't immediately transfer 100% of the spend.
A good progression is:
Qualification → sample → pilot PO → performance monitoring → partial allocation → full approval
Track the first 3–6 months closely:
Then feed those results back into your supplier scorecard.
Don't make "lowest price" your supplier-selection strategy.
For raw materials, the real objective is usually:
Lowest total cost at an acceptable level of quality and supply risk.
A supplier with excellent pricing but weak traceability, questionable financial health, poor process control or limited capacity can become extremely expensive after qualification.
If you're building this process from scratch, I'd create three standard documents: a Supplier Pre-Qualification Questionnaire, a Supplier Audit Checklist, and a weighted Supplier Scorecard. That gives Purchasing, QA, Engineering and Finance one consistent approval process instead of each department evaluating suppliers differently.

The strongest purchasing organizations don't rely on a single source for new suppliers. They use a structured sourcing and qualification process that reduces risk while keeping a healthy pipeline of alternatives.
A practical approach looks like this:
| Stage | What to do | Goal |
|---|---|---|
| 1. Identify suppliers | Search industry directories, trade shows, referrals, sourcing platforms, customer recommendations, and competitor supply chains where appropriate | Build a long list |
| 2. Pre-screen | Review capabilities, certifications, product range, production capacity, export experience, and financial stability | Remove poor fits early |
| 3. Request information | Send an RFI (Request for Information) or supplier questionnaire | Compare suppliers consistently |
| 4. Evaluate | Score suppliers using weighted criteria | Create an objective shortlist |
| 5. Validate | Conduct audits, sample orders, and quality testing | Confirm real performance |
| 6. Approve | Add successful suppliers to an Approved Vendor List (AVL) | Enable purchasing |
Some of the best sources include:
Rather than relying on one supplier for critical materials, many procurement teams intentionally qualify two or three suppliers for each key commodity to improve resilience.
Price is important, but it should be only one part of the decision.
A typical supplier scorecard might include:
| Criteria | Typical Weight |
|---|---|
| Product quality | 30% |
| Cost competitiveness | 20% |
| Delivery performance | 20% |
| Manufacturing capability | 10% |
| Financial stability | 10% |
| Technical support & responsiveness | 5% |
| Sustainability & compliance | 5% |
The exact weighting should reflect your business priorities. For example, manufacturers producing safety-critical products often give quality a much higher weighting than cost.
Before approving a new raw material supplier, request:
A risk-based qualification process is widely recommended, with more rigorous reviews for suppliers providing critical materials or single-source components.
For strategic suppliers, an on-site or virtual audit can reveal issues that documents alone cannot.
Review areas such as:
Before awarding significant business:
Many companies increase inspection frequency for the first few deliveries before granting full approval.
Qualification shouldn't end after approval. Track KPIs such as:
Community discussions among procurement professionals consistently recommend building scorecards from your own ERP, receiving, inspection, and accounts payable data rather than relying primarily on supplier-reported metrics.
Be cautious if a supplier:
This structured process helps balance cost, quality, delivery, and supply continuity while creating an audit trail that supports consistent procurement decisions.
The strongest purchasing organizations treat supplier discovery and supplier qualification as two separate processes: 1. **Find a broad pool of potential suppliers.** 2. **Reduce risk through a structured qualification process before award
The strongest purchasing organizations treat supplier discovery and supplier qualification as two separate processes:
Here's a practical approach that works across most manufacturing industries.
Before contacting suppliers, clearly define:
The clearer your requirements, the easier it is to compare suppliers fairly.
Don't rely on Google alone. Use multiple sources:
Aim to identify 10–20 candidates initially.
Before requesting quotes, eliminate obvious risks.
Review:
Many companies use a supplier questionnaire during this stage to collect standardized information. Risk-based qualification is generally recommended, with more scrutiny for suppliers of critical materials.
Ask for:
Never qualify a supplier based only on marketing brochures.
A simple example:
| Category | Weight |
|---|---|
| Quality capability | 30% |
| Cost / Total Cost of Ownership | 20% |
| Delivery performance | 20% |
| Technical support | 10% |
| Capacity & scalability | 10% |
| Financial stability | 5% |
| Sustainability & compliance | 5% |
Notice that quality and delivery typically outweigh unit price. Research and industry practice consistently show that total cost—including defects, delays, and switching costs—is a better decision metric than purchase price alone.
For critical raw materials, conduct either:
Evaluate:
A supplier with impressive documentation but weak shop-floor practices is a significant risk.
Instead of immediately awarding annual business:
Many organizations treat this as a probationary period before full approval.
After onboarding, track objective KPIs such as:
Many experienced procurement professionals recommend using your own ERP, receiving, quality, and accounts payable data rather than relying on supplier-reported performance.
Avoid relying on a single source for critical materials whenever practical.
For high-risk materials:
Community discussions among procurement professionals frequently emphasize qualifying alternate sources before problems arise, since qualifying a replacement can take many months in some industries.
Before approving a new raw material supplier, confirm:
This structured approach helps move supplier selection from intuition to a repeatable, evidence-based process, improving both supply continuity and long-term purchasing performance.

Here's a practical approach you can use:
Before contacting suppliers, document:
Clear specifications reduce misunderstandings and make supplier comparisons much easier.
Look beyond your current vendor list by using multiple channels:
Avoid depending on a single source for supplier discovery.
Create a standard supplier questionnaire covering:
A structured qualification process is generally more reliable than selecting suppliers based only on price or familiarity. Risk-based qualification is widely recommended, with more rigorous evaluation for critical materials.
Ask suppliers to provide:
Your engineering or quality team should verify that the supplier can consistently meet your specifications.
For strategic or high-risk raw materials, perform:
Look beyond certifications to understand how the supplier manages quality problems, production changes, and corrective actions.
Before awarding major business:
A small pilot order often reveals issues that paperwork alone won't.
Review:
A supplier with attractive pricing but weak financial stability can become a costly risk.
A weighted scorecard helps remove bias. For example:
| Criteria | Weight |
|---|---|
| Quality | 30% |
| Cost | 20% |
| Delivery performance | 20% |
| Technical capability | 15% |
| Financial stability | 5% |
| Service & responsiveness | 5% |
| Sustainability & compliance | 5% |
Adjust the weights based on how critical the material is.
Supplier approval isn't a one-time event. Track:
Review supplier performance quarterly or semiannually and maintain an Approved Supplier List (ASL).
For critical raw materials:
Be cautious if a supplier:
This structured process helps reduce supply disruptions, improve material quality, and create a more resilient supply base over time.

The strongest supplier sourcing process combines broad market discovery, structured qualification, and performance validation. Rather than choosing suppliers based primarily on price, successful purchasing teams build an approved supplier pipeline that balances cost, quality, risk, and long-term reliability.
Here's a practical approach:
| Step | What to do | What to evaluate |
|---|---|---|
| 1. Define requirements | Create clear material specifications | Grade, tolerances, certifications, annual volume, lead time |
| 2. Find suppliers | Use multiple sourcing channels | Manufacturers, distributors, trade shows, industry associations, sourcing platforms, referrals |
| 3. Pre-screen | Eliminate unsuitable suppliers | Manufacturing capability, certifications, capacity, financial stability |
| 4. Request information | Send an RFI/RFQ | Pricing, MOQs, lead times, payment terms, logistics |
| 5. Validate | Review samples and documentation | Quality, consistency, traceability, technical support |
| 6. Qualify | Conduct audits if appropriate | Quality systems, production controls, risk management |
| 7. Trial orders | Start with limited purchases | Delivery performance, responsiveness, defect rate |
| 8. Monitor | Use supplier scorecards | Quality, cost, delivery, service, continuous improvement |
Good purchasing managers rarely rely on a single source. Consider combining:
Using multiple channels often uncovers suppliers that competitors may overlook.
Before approving a supplier, verify:
Business
Quality
Operations
Supply chain
Commercial
A structured, risk-based qualification process is widely recommended because supplier approval should demonstrate consistent capability—not simply add a vendor to the ERP system.
An ISO certificate is valuable, but it doesn't guarantee consistent performance.
Ask suppliers for:
Many experienced procurement professionals emphasize that repeatable execution is a better indicator than marketing materials or certifications alone.
For high-risk or business-critical raw materials, consider:
Regulated industries often require supplier verification before approval and periodic re-evaluation thereafter, with higher-risk suppliers receiving more extensive audits.
Instead of immediately awarding large contracts:
Many supplier qualification frameworks recommend trial orders because actual delivery performance often reveals issues that paperwork cannot.
Measure suppliers consistently using KPIs such as:
| KPI | Typical Target |
|---|---|
| On-time delivery | ≥95% |
| Defect rate | <1% (varies by industry) |
| Response time | <24 hours |
| Lead-time consistency | Within agreed tolerance |
| Cost competitiveness | Annual review |
| Corrective action closure | Within agreed SLA |
Review these monthly or quarterly and classify suppliers as:
Be cautious if a supplier:
Many mature procurement organizations maintain an Approved Vendor List (AVL). New suppliers typically progress through stages such as:
This structured approach reduces supply risk while encouraging competition and ensuring the supplier base remains capable, compliant, and resilient.
