Supplier Verification Checklist: Documents Every Vietnamese Factory Should Provide

A supplier verification checklist is the set of documents you collect and confirm before trusting a factory. It proves the supplier is legally registered, capable, and export-ready. Complete it before you send any deposit.

Many buyers judge a supplier on a slick catalog and fast replies. Documents tell the real story. At VALO Vietnam, we verify factories for a living. Paperwork is where legitimacy is proven or exposed.

This supplier verification checklist lists every document a Vietnamese factory should provide. You will learn what each one proves and how to confirm it. Use it before you commit to any order.

Key Takeaways

• Verify with documents, not impressions. A professional pitch is not proof of a real factory.
• Start with legal registration. A business license and tax records confirm the company exists.
• Confirm capability. Certifications, test reports, and capacity data prove they can deliver.
• Check export readiness. Export records and a certificate of origin matter for shipping.
• Cross-check everything. Verify documents against official records, not just the copies you receive.

What Is a Supplier Verification Checklist

A supplier verification checklist is a document-based vetting tool. It confirms a factory is legitimate, capable, and safe to pay. You work through it before any commercial commitment.

The checklist has three document groups. Legal papers prove the company exists. Capability papers prove it can produce. Export papers prove it can ship.

Verification is not the same as qualification. Qualification scores a supplier against your needs. Verification simply confirms they are real and legal.

Why Documents Beat Promises

Promises are easy to make and hard to trust. Documents are harder to fake and easy to check. That is why paperwork sits at the center of verification.

A legitimate factory provides documents without hesitation. Delay or excuses are a warning sign in themselves. Real manufacturers are proud of their credentials.

For the broader vetting process, see our guide to supplier due diligence Vietnam.

The Core Legal Documents

Legal documents are the foundation of verification. They confirm the company is a registered business. Never skip this group.

Business Registration Certificate

The business registration certificate is the single most important document. In Vietnam it is the enterprise registration certificate. It confirms the company legally exists.

Check the registered business scope on the certificate. A factory should list manufacturing or production. A trading scope means you may be dealing with a middleman.

Tax and VAT Registration

Tax registration confirms the company is active and compliant. Ask for the tax code and VAT registration. These link the business to official records.

A registered tax code lets you cross-check the company. It also signals a business that operates in the open. Missing tax records are a serious concern.

Bank Account Details

Confirm the company's official bank account before you pay. Payment should go to the registered business, never an individual. A personal account is a classic fraud signal.

Match the bank account name to the business license. Any mismatch deserves a hard pause. Legitimate factories are always paid as companies.

Capability and Quality Documents

Legal existence is not enough. You also need proof the factory can produce your product. These documents confirm real capability.

Certifications and Test Reports

Ask for every certification the factory claims. Common examples include ISO and industry-specific standards. Request the certificate numbers, not just logos.

Test reports prove the product meets your standards. Ask for reports from recognized labs. Confirm the reports match your product and market.

• Certificates of analysis for materials or products.
• Compliance certificates for your target market.
• Third-party test reports with lab names and dates.

Falsified or expired certificates are common. Verify each one against the issuing body.

Factory Profile and Capacity

A factory profile shows scale and experience. It should include location, size, and staff count. It should also list main products and clients.

Ask for capacity information in writing. Confirm the factory can handle your order volume. A mismatch here causes delays and quality drops.

Request timestamped photos or video of the production floor. A showroom is not a factory. You want to see real lines and equipment.

References From Other Buyers

Ask for references from current export clients. A genuine factory can share a few names. Contact them with specific, direct questions.

Good references reveal reliability over time. They show how the factory handles problems and delays. One honest reference can save a bad order.

Export and Trade Documents

Export readiness is often overlooked. A capable factory is not always an experienced exporter. These documents confirm they can ship to you.

Export License and History

Ask about the factory's export experience. Request records of past shipments to your region. Export history shows they can handle customs and paperwork.

A first-time exporter is not always a risk. But it does mean more support is needed. Know this before you plan your timeline.

Certificate of Origin and Shipping Papers

The certificate of origin confirms where goods are made. It affects duties and market access. Confirm the factory can provide it correctly.

Learn why this document matters in our guide to the certificate of origin.

Also confirm they can issue commercial invoices and packing lists. These are basic export documents. A real exporter provides them as standard.

How to Verify the Documents

Collecting documents is only half the job. You must confirm they are genuine. Verification is what turns paper into proof.

Cross-Check Against Official Records

Do not trust a copy at face value. Check the business registration against official registries. Confirm the company name, address, and scope match.

Verify certifications with the issuing body. A real certificate can be confirmed at the source. This step catches most forged documents.

VALO Vietnam's view: The buyers who get burned rarely skip every check. They skip the last one. They collect the documents, feel reassured, and never confirm them against official records. Verification only works when you finish it. A document you did not check is a promise, not proof.

Confirm With a Live Factory Tour

Ask for a live video tour of the factory floor. A legitimate supplier will agree without fuss. Refusal or endless delay is a red flag.

For a deeper check, use a professional audit. Our overview of supplier audit services in Vietnam explains your options. An on-site audit verifies documents against reality.

Red Flags in Document Requests

How a supplier handles your requests is revealing. Cooperation is a good sign. Resistance is a warning.

Treat these as red flags:

• Refusing to share a business license or tax code.
• Delaying simple document requests for weeks.
• Sending certificates you cannot verify at the source.
• Avoiding a live tour of the production floor.

Spot several of these together, and stop the process. Our guide on how to avoid a sourcing scam covers the warning signs in detail.

Build a Repeatable Verification File

Do not verify from scratch for every supplier. Keep a standard verification file for each factory. Store every document and every check in one place.

A consistent file makes suppliers easy to compare. It also creates a record you can revisit later. Re-verify long-term partners on a regular schedule. A verified supplier today can still drift over time.

Pair verification with a structured scorecard. Our supplier qualification checklist helps you rank verified suppliers. Start your search with our guide on how to find suppliers in vietnam.
