China factory audit and supplier verification
Before you wire a deposit, get eyes on the actual production line. Our Foshan-based team audits factories in person across the Greater Bay Area — capacity, equipment, certifications, and the people you will really be dealing with. Every factory on ChinaMakersHub is already on-site audited, and we can verify a supplier you found yourself.
What a CMH audit actually checks
A factory audit is only useful if it looks past the showroom. Our team walks the line that would make your product, in the category you are sourcing — then reports back in plain language. See the full method in our 27-point China factory audit checklist.
The real production line
We inspect the line that runs your specific product category — machines, workstations and in-process checks — not a polished sample room set up for visitors.
Capacity and equipment
Actual monthly capacity, key equipment and headcount, so the numbers in a quote match what the floor can really deliver.
Certifications and documents
Business licence, export filing and product certifications (CE, REACH, ISO, GMP and the like) checked against the originals — see our guide to ISO certifications explained.
The people you will deal with
Every verified profile carries an audit date and the name of the person you will actually work with — no anonymous middleman between you and the workshop.
Two ways to get a factory verified
1 · Start with an already-audited factory
Browse verified factories by category. Each one has been on-site audited, with capacity, certifications and audit date on the profile. Ask and we will share the audit notes — we do not gate our own reports behind a paywall. This option is free.
2 · Commission an audit on a factory you found
Sourced a supplier elsewhere and want a second pair of eyes? Our Foshan team can visit it, walk the line and report back before you commit. For a first-time program we charge a small auditing fee that is credited back against your first order.
Not sure whether you need a full audit or a quick factory visit? Our guide on when to hire a China factory-visit agent and visiting Chinese factories walk through both.
Factory audit questions
Does ChinaMakersHub offer factory audits in China?
Yes. A Foshan-based team audits production in person across the Greater Bay Area. Every factory we list has already had an on-site audit, and we can audit or re-visit a specific factory before you order.
How much does a China factory audit cost?
Browsing already-audited factories here is free, and we share audit notes on request. For a factory you found yourself, or a first-time program, we charge a small auditing fee that is credited back against your first order — contact us for a quote.
Can you visit a factory I found myself?
Yes. Because the team is in Foshan, they can visit a factory you sourced elsewhere, walk the production line, and report back before you commit.
What does the audit check?
The production line for your specific category — not just the showroom — plus real capacity, equipment, certifications, export documentation, and the contact you will actually deal with.
Where is your audit team based?
In Foshan, Guangdong, inside the Greater Bay Area cluster — so audits and visits are done in person, not outsourced sight-unseen.
How do I evaluate a supplier before the audit?
Start with our supplier scorecard and factory-vs-trading-company guide, then book the on-site audit to confirm what you cannot see remotely.
