Supplier Verification Checklist for Chinese Factories: Step-by-Step Guide

Before You Start: Why Sequence Matters

Each verification step builds on the previous one. Step 1 is fast and cheap. Step 7 is comprehensive and requires more investment. You do not need to do all of them for every supplier — but the ones you skip are the ones that will cause problems.

The most common mistake I see: businesses spend weeks negotiating with a supplier, visiting sample rooms, and exchanging documents — and then discover at Step 3 that they have been talking to a trading company the entire time.

Do the steps in order. Stop when you have enough information to make a decision. Never skip to negotiating before you have verified who you are actually dealing with.

Step 1: Business License Check

Time: 30 minutes Cost: Free Risk if skipped: High

The first thing to verify is whether the company exists and what it is legally registered to do.

Go to samr.gov.cn — China's State Administration for Market Regulation registry. Search by the company's unified social credit code or full Chinese name.

What to check:

• Business scope: Does it include manufacturing, production, or processing? If it only lists wholesale, export, or trade, you are dealing with a trading company.
• Registered address: Note this exactly. You will verify it in Step 3.
• Company status: Is it active? Any abnormal business notices?
• Registered capital: Not a guarantee of capability, but a zero or unusually low registered capital is worth noting.

What this catches: Companies that are legally trading companies, not factories. Companies with outstanding legal notices. Shell companies with no real operations.

Step 2: Certificate Verification

Time: 2 hours Cost: Free Risk if skipped: High

If the supplier has provided quality certifications — ISO 9001, CE, CB, or anything else — verify them directly with the issuing body.

Do not accept files or screenshots. Every legitimate certification body has an online verification portal. If the certificate is real, the number will verify. If it does not, you have a problem.

What to check for each certificate:

• Does the certificate number exist in the issuing body's database?
• Does the company name on the certificate match the company you are negotiating with?
• Is the certificate current and not expired?
• Does the scope of certification cover the product you are ordering?

What this catches: Expired certificates. Certificates belonging to different companies. Certificates that cover different product categories than what you are ordering. Fabricated certificates.

---

Step 3: Address Verification

Time: 30 minutes Cost: Free Risk if skipped: High

Take the registered address from Step 1 and put it into Google Maps or Baidu Maps.

What to check:

• Is it an industrial zone or a commercial/residential area?
• Does the satellite imagery show a factory building or an office building?
• Is there any sign of a production facility — warehouse structures, loading docks, industrial parking?

Then: ask the supplier where their factory is. Compare that address to the registered address. If they do not match, ask why before proceeding.

What this catches: Registered addresses that point to office buildings instead of factories. Suppliers whose stated location does not match their registered location. Businesses that have moved to avoid detection.

---

Step 4: Product Range and MOQ Analysis

Time: 1 hour Cost: Free Risk if skipped: Medium

Review what the supplier is offering and how they are offering it.

What to check:

• How many unrelated product categories does this supplier offer? More than three or four categories in different industries suggests aggregation from multiple factories.
• What is the minimum order quantity? Very low MOQ across a wide catalog suggests the supplier is a trading intermediary.
• What is included in the quoted price? Vague pricing that does not specify tooling, setup, or packaging costs is a red flag.
• Can they describe the production process for your specific product? Ask about raw materials, equipment, and quality checkpoints.

What this catches: Trading companies posing as one-stop shops. Suppliers whose quoted price does not reflect actual manufacturing costs.

---

Step 5: Live Video Walkthrough

Time: 1-2 hours to arrange, 30-60 min call Cost: Free (if supplier arranges) Risk if skipped: High

Request a live video walkthrough of the production facility — specifically the line that would handle your order. Not a curated tour. Not pre-recorded footage. A live walkthrough where you can see active production.

What to check:

• Are machines operational? A facility with all equipment turned off during a scheduled visit is suspicious.
• Is the production scale consistent with what was quoted? You should be able to see production lines relevant to your order.
• Is the facility organised? Clean facilities with visible QC stations indicate better management.
• Do the workers and equipment match the production scale claimed?

If the supplier deflects, makes excuses, or offers to send photographs instead, that is itself the information you need.

What this catches: Factories that are smaller than advertised. Facilities that are not actively producing. Trading companies that have no production capability at all.

---

Step 6: Reference Check

Time: 2-3 hours Cost: Free Risk if skipped: Medium

Ask the supplier for references from buyers in your region or industry. Specifically ask for companies in Australia, New Zealand, or other similar markets.

What to check:

• Call or email the reference directly. Ask about their experience with this supplier.
• What was the quality consistency like across multiple orders?
• Did the supplier communicate responsively?
• Were deliveries on time and to specification?
• Would they work with this supplier again?

What this catches: Suppliers who perform well initially but deteriorate over time. Communication problems that do not surface in first-contact conversations. Quality inconsistency that only shows up after repeated orders.

---

Step 7: On-Site Factory Audit

Time: 5-10 business days to arrange and conduct Cost: AUD 800-2,000 for independent audit Risk if skipped: Low (if Steps 1-6 were completed and passed)

If Steps 1-6 have gone well and you are considering a significant order, conduct a physical audit of the facility.

An on-site audit verifies everything from Steps 1-6 in person and adds:

• Physical inspection of equipment condition and maintenance
• Observation of active production and worker count verification
• Review of actual quality control processes and documentation
• Confirmation of the supplier's production capacity against claims
• Verification that the factory shown in the video matches the actual facility

We conduct these audits for clients. An independent auditor spends one to two days at the facility and produces a written report with photographs.

What this catches: Everything previous steps catch, plus physical discrepancies that documents and video cannot reveal.

The Decision Framework

Complete Steps 1-3 before you spend significant time negotiating. These take under three hours total and catch most problems.

Complete Steps 4-5 before you request a sample or pay any deposit.

Complete Step 6 before you commit to a first order.

Complete Step 7 for orders above AUD 30,000 or where you need confidence in production capacity.

If You Find a Red Flag

Stop. Do not proceed to the next step until you have an explanation that makes sense.

Common responses to red flags and what they mean:

• "Our factory is a partner facility, not our primary production site" — you are dealing with a trading company. Ask who the actual manufacturer is.
• "The certificate is under our parent company" — verify this independently. The certificate must cover the legal entity producing your goods.
• "We cannot do a video call right now" — push for a specific time. Consistent deflection means something is wrong.
• "The address on our website is our marketing office" — this may be legitimate. Verify the actual factory address and check it independently.

FAQ

What is the minimum verification I should do for a small first order?

Steps 1-3 (business license, certificate verification, address check) are the minimum for any order. If anything is unclear at Step 3, do not proceed.

How much does a full audit cost?

Remote verification (Steps 1-5) costs nothing except your time. An on-site audit by an independent inspector in China typically costs AUD 800-2,000 depending on the complexity and location. We handle this for clients as part of our service.

Can I skip steps if the supplier seems professional?

Professional presentation is not verification. Trading companies invest more in presentation than actual factories do. Every step exists because the previous step's failures are not visible without the next step.

What if a supplier refuses one of the verification steps?

Treat refusal as a red flag. Legitimate factories doing business internationally are accustomed to verification requests. Refusal to verify is itself significant information.

How long does the full verification process take?

Steps 1-3 can be completed in a single day. Step 5 (video walkthrough) takes 1-2 weeks to schedule. Step 7 (on-site audit) takes 2-4 weeks including scheduling.
