Supplier Verification Guide
Verification checklist for international sourcing

Analysis
A catalogue or website does not prove that a supplier is the manufacturer. Independently verify registration, facility address, quality certificates, product standards and beneficiary bank details.
Practical approach
Validate samples, technical data, references and shipping documents before ordering. Confirm any bank-account changes through an independent channel and perform relevant sanctions screening.
Verification sequence
First confirm legal registration and authorised contacts; then validate facilities, technical specifications and certificate validity. Verify bank details on the pro forma invoice through an independent channel. Escalate to site audits or third-party inspection as risk rises.
Decision framework
Before acting, document the product scope, destination market, verifiable sources, responsible parties and material risks. Compare alternative scenarios and recheck variable information such as regulations and prices at the time of transaction.
Verification sequence
First verify legal registration, then the facility's product scope, certificate issuers, and finally the contracting seller and bank account. Confirm bank changes through an independently verified existing channel.
Implementation checklist
- Document product, destination market and commercial scope.
- Link source documents, specifications and accountable owners.
- Compare at least two cost and delivery scenarios.
- Record risks, approvals and review dates.
- Revalidate current regulations and quotation terms before committing.
Frequently asked questions
What is the first step?
Define the product, target market, quantity and commercial priorities.
Is the information current?
Regulations, prices and logistics conditions change; confirm them with primary sources before transacting.
Is a certificate proof of reliability?
No. Its validity, scope and connection to the actual production site require separate verification.
How do you distinguish a producer from a trader?
Verify plant address, production evidence and contracting seller separately; trading is not inherently problematic.
What if bank details change?
Do not change payment instructions without callback verification through an independently established channel.
Is a COA sufficient by itself?
No. Check batch identity, methods, laboratory competence and specification alignment.
Why place a trial order?
It exposes quality, packaging, delivery and communication issues documents cannot reveal.
