Supplier Verification Guide

Supplier evaluation: How to verify a Supplier before you sign a contract in Global Trade

Don’t rely on sales decks. Real trade data reveals the truth.

Meet Sarah Mitchell, a Procurement Manager who learned the hard way: supplier claims don’t equal performance. Now she verifies every supplier with real shipment data before signing any contract.

Volza's Company Profiler shows me the truth suppliers hide. I check 24-month shipment history before any RFQ, it's saved me from three failing suppliers this year alone.

The Problem
Sarah’s supplier promised 10,000 units monthly. Delivered 6,000. Production line halted. The supplier had great references and a polished website — but declining shipment volumes for 6 months before she signed.
The Insight
Supplier claims are marketing. Real verification requires trade data: actual shipment volumes, buyer retention, category specialization, and consistency signals over 24 months.
The Solution
Sarah built a 7-step supplier evaluation framework that translates supplier claims into verifiable facts. Combined with Volza’s Company Profiler, she now checks trade history before RFQ — not after the contract is signed.

Frequently asked questions

What is supplier evaluation in global trade?

Supplier evaluation is the systematic process of assessing potential suppliers before entering into business relationships. In global trade, this involves verifying trade history, shipment patterns, market presence, and risk factors using data from customs records, shipping manifests, and financial indicators to ensure suppliers can reliably deliver goods across international borders.

What are the biggest red flags in supplier onboarding?

Key red flags include: inconsistent shipment patterns (gaps of 3+ months), heavy reliance on a single buyer (>50% concentration), mismatched HS codes versus claimed specialization, no shipments to your target market, declining year-over-year volumes, and inability to provide references from existing buyers in similar industries.

How do freight and duties affect supplier selection?

Landed cost (product price + freight + duties) often reveals true competitiveness. A cheaper supplier may become expensive after duties, especially for products with complex HS classifications. Use tools like Freight Optimizer and Duty Minimizer to calculate total landed cost and compare suppliers on an apples to apples basis before selection.

How do I verify a supplier before RFQ?

Before sending an RFQ, verify suppliers by checking their actual shipment history (not just claimed capacity), reviewing their consistency over 24+ months, confirming they regularly export your specific HS codes, validating their presence in your target markets, and analyzing concentration risks. Tools like Company Profiler can reveal this trade data directly from customs records.

How do I check if a supplier can scale?

Verify scalability by examining repeat shipment rhythm (monthly vs. sporadic), buyer diversity (multiple customers vs. concentration), year over year growth trends, and corridor breadth (ability to serve multiple markets). A supplier with consistent monthly shipments to diverse buyers demonstrates operational capacity to scale.

What should I include in a supplier risk assessment template?

A comprehensive template should include: supplier identification details, product/HS code specifications, target market, risk rating (Low/Medium/High), and a controls checklist covering phased ramp schedules, SLA triggers, dual-source requirements, safety stock buffers, audit schedules, and escalation paths. This creates an approval ready document for leadership review.

Don’t order blind. Verify supplier reality before contract.

Sarah stopped signing contracts blind by following this framework. Now you can too verify every supplier with real trade data before committing to any contract.
