Supplier & Vendor Research

Research, evaluate, and compare suppliers and vendors for B2B procurement. Build vendor shortlists, evaluation matrices, and RFP frameworks.

When to Use

• User needs to find suppliers for a product, service, or component
• User wants to evaluate and compare vendors
• User needs an RFP or vendor evaluation framework
• User asks about procurement best practices
• User wants to assess supplier risk or negotiate better terms

When NOT to Use

• Personal product shopping (use personal-shopper skill)
• Competitive market analysis (use competitive-analysis skill)
• Software/SaaS evaluation only (use deep-research skill)

Methodology

Step 1: Requirements Definition

Before researching suppliers, clarify:

What you need:

• Product/service specification (be specific)
• Volume/quantity requirements
• Quality standards and certifications needed
• Timeline and delivery requirements

Constraints:

• Budget range
• Geographic preferences (domestic, nearshore, offshore)
• Compliance requirements (ISO, SOC2, GDPR, industry-specific)
• Minimum order quantities
• Payment terms preferences

Step 2: Supplier Discovery

Match the directory to the sourcing geography. Use

webSearch

+

webFetch

against these:

Platform	Coverage	Best for	Caveat
Thomasnet	500k+ North American suppliers	US/Canada industrial — machinery, plastics, metals, custom components. Free for buyers. Filter by ISO certs + CAD availability.	US-only; no pricing shown
Alibaba	200k+ suppliers, 200M+ SKUs	China/Asia, prototype sampling, MOQ benchmarking across 5,900 categories	Many "manufacturers" are trading companies — verify with customs data
Global Sources	Asia, audited	Electronics, consumer goods. Stronger supplier audits than Alibaba.	Smaller catalog
IndiaMART	India	Textiles, chemicals, pharma intermediates, generics	Data quality varies widely
Kompass / Europages	EU	EU-based sourcing when GDPR/CE compliance matters	Limited free tier
ImportYeti (free)	US ocean freight records	Verification, not discovery. Look up a supplier to see real US customs shipment history — who they actually ship to, how often, what volume. Exposes trading companies posing as factories.	Sea freight only, US imports only
Panjiva / ImportGenius	Global trade data	Competitor supply chain mapping — find out who your competitors buy from	Paid, learning curve

Agent search patterns:

• site:thomasnet.com "[product] manufacturer" [state]

  — direct directory scrape

• site:alibaba.com "[product]" "verified supplier" "trade assurance"

  — pre-filtered for badges

• webFetch: importyeti.com/company/[supplier-name]

  — verify real export activity before engaging

• "[competitor product name]" "made in" OR "manufactured by"

  — reverse-engineer competitor supply chains

• site:alibaba.com "[product]" MOQ

  — quickly benchmark minimum order quantities across suppliers

2025 geography shift: Vietnam, India, and Mexico are the primary China+1 alternatives. Mexico benefits from USMCA (no tariffs, 3-5 day freight vs 30+ from Asia). Vietnam is strong in furniture/electronics assembly. India is strong in textiles/pharma/software.

Target: 8-12 candidates for RFI, narrow to 3-5 for RFQ.

Step 3: Vendor Evaluation Matrix

Score each vendor across weighted criteria:

Category	Weight	Criteria
Quality	25%	Certifications, defect rates, QC processes, samples
Cost	20%	Unit price, total cost of ownership, volume discounts, hidden fees
Delivery	20%	Lead times, on-time delivery rate, shipping methods, inventory
Capability	15%	Production capacity, scalability, technology, R&D
Reliability	10%	Financial stability, years in business, references, insurance
Compliance	10%	Regulatory compliance, certifications, ESG practices, data security

Scoring scale: 1 (poor) to 5 (excellent) per criterion.

Total Cost of Ownership (TCO): Don't just compare unit prices. Include:

• Purchase price
• Shipping and logistics
• Import duties and taxes
• Quality inspection costs
• Inventory carrying costs
• Switching costs
• Risk costs (what if they fail to deliver?)

Step 4: Verification & Risk Assessment

Verify the factory is real (the #1 failure mode in overseas sourcing):

• Customs data cross-check:

  webFetch

  the supplier on ImportYeti — consistent monthly shipments to recognizable brands = real factory. Zero export history or shipments only to shell companies = trading company or fraud.
• Certificate verification: Don't trust uploaded PDFs. ISO 9001 certs have a cert number — verify on the issuing body's site (SGS, BV, TÜV, Intertek all have public lookup tools).

  webSearch: "[cert body] certificate verification [cert number]"

  .
• Business license: For China, request the Unified Social Credit Code (18 digits) — verifiable on the National Enterprise Credit system. For US, check state Secretary of State filings.
• Address verification:

  webSearch

  the factory address — Google Maps satellite view should show an industrial facility, not a residential block or office tower.
• Alibaba badges: "Verified Supplier" means a third party (SGS/BV) physically visited. "Gold Supplier" just means they paid a fee — it verifies nothing.

Risk dimensions:

Risk type	Check	Red flags
Financial	D&B report, years in business, customer concentration	<3 years operating, >40% revenue from one customer, requests 100% upfront payment
Operational	Factory count, capacity utilization, QC process docs	Single facility, no in-house QC team, won't allow video factory tour
Geopolitical	Tariff exposure (Section 301 for China), sanctions lists (OFAC SDN list), port stability	Sourcing region on UFLPA entity list, currency controls, single-port dependency
Compliance	UFLPA (Xinjiang forced labor — US presumes guilt for flagged regions), EU CSDDD due-diligence rules (2024+), conflict minerals (3TG)	Can't provide tier-2 supplier list, cotton/polysilicon from Xinjiang, no chain-of-custody docs
Supply chain	Tier-2 dependencies, raw material source, seasonal capacity (Chinese New Year = 4-6 wk shutdown)	Won't name their material suppliers, capacity claims exceed facility size

Step 5: RFP/RFQ Process

If conducting a formal selection:

RFP structure:

1. Company overview and project background
2. Scope of work / product specifications
3. Volume and timeline requirements
4. Quality and compliance requirements
5. Pricing format (line item breakdown)
6. References (3+ similar clients)
7. Evaluation criteria and weights
8. Timeline for responses and decision

Evaluation process:

1. Distribute RFP to shortlisted vendors (3-5)
2. Allow Q&A period
3. Score responses against evaluation matrix
4. Conduct reference checks for top 2-3
5. Request samples or pilot project
6. Negotiate final terms with preferred vendor
7. Award and onboard

Step 6: Negotiation Preparation

Levers ranked by typical yield:

1. Volume commitment — annual forecast (even non-binding) usually unlocks 8-15% off spot pricing
2. Payment terms — overseas default is 30% deposit / 70% pre-shipment. Pushing to 30/70 after delivery, or Net 30 from shipment, is worth 2-5% of unit cost in cash flow
3. Incoterms — know the difference: FOB (you pay freight + insurance from port), CIF (supplier pays to your port, but you bear risk in transit — worst of both), DDP (supplier handles everything including customs — most expensive, least risk). FOB is the standard for experienced buyers.
4. MOQ flexibility — first-order MOQ is almost always negotiable down 30-50% if you frame it as a paid trial. "We'll pay the higher per-unit price on 500 units to validate, then commit to your 2,000 MOQ."
5. Tooling/mold ownership — for custom parts, negotiate that you own the mold after paying for it. Otherwise you're locked in forever.

Contract terms that matter most:

• Price escalation clause — cap annual increases at a named index (e.g., PPI for the material category), not "supplier discretion"
• Quality SLA with teeth — define AQL (Acceptable Quality Level — typically 2.5 for general goods, 1.0 for critical components), specify who pays for third-party inspection (QIMA, SGS), and define the remedy (rework at supplier cost, not just credit)
• Lead time + late penalties — industry norm: 1-2% of order value per week late, capped at 10%
• IP protection — NNN agreement (Non-disclosure, Non-use, Non-circumvention) for China, not a US-style NDA — US NDAs are unenforceable in Chinese courts
• Exit clause — right to terminate with 60-90 days notice, obligation to complete in-flight orders, tooling transfer terms

Best Practices

1. Never single-source critical components — maintain a qualified backup at 10-20% of volume even if unit cost is higher
2. Sample → pilot → scale — paid samples first, then a pilot run of 5-10% of target volume, then commit. Never skip to full MOQ.
3. Third-party inspection before final payment — QIMA, SGS, or Bureau Veritas run pre-shipment inspections for ~$300. Cheaper than one bad container.
4. Back-channel references — find their customers via ImportYeti shipment records and cold-email them. Supplier-provided references are curated.
5. Plan around Chinese New Year — factories shut 4-6 weeks (late Jan/Feb). Orders placed in December ship in March. Build buffer inventory by November.
6. Landed cost, not unit cost — a $2.00 unit from China can land at $3.50 after freight, 25% Section 301 tariff, duty, and inspection. A $2.80 unit from Mexico under USMCA might land at $3.10.

Limitations

• Cannot access paid databases (Panjiva, D&B, ImportGenius full data) — ImportYeti free tier is the workaround for US import verification
• Cannot physically inspect facilities or samples — always recommend third-party audit for orders >$10k
• Cannot verify certificate authenticity directly — provides the lookup URLs for the user to check
• Tariff rates and trade rules change frequently (Section 301, UFLPA scope) — verify current rates at time of order
• Pricing from directory listings is indicative only — real quotes require RFQ with full specs
