A factory audit checklist is the fastest way to find out whether the supplier behind a polished Alibaba page is a real manufacturer with the capacity, quality system and legal standing to deliver your order. Most buyers skip it, pay a 30 percent deposit, and only discover the truth when the goods arrive late and wrong.
Our team has audited hundreds of factories since 2016. This guide covers when to audit, which type to run, the full factory audit checklist we use on site, how we score it, and the red flags that end a visit early.
Key takeaways
- Audit every new supplier before paying a deposit on any order above roughly USD 10,000, and re-audit long-term partners every one to two years.
- Check nine areas: legal, facilities, capacity, quality system, engineering, social and safety, environmental, financial stability and references.
- Score each section and set a go/no-go threshold before the visit, not after, so the result is not swayed by a friendly factory boss.
- A one-day China factory audit costs USD 300 to 800 and routinely saves ten times that on a single order.
- An audit is not an inspection. The audit qualifies the factory; the inspection checks the goods.
When a factory audit is worth the money
Not every purchase needs a formal supplier audit in China. A USD 2,000 test order can go ahead on a video call and a sample. The calculation changes as the stakes rise:
- New supplier, meaningful order. Any first order where the deposit would hurt if it disappeared. For most of our clients that threshold is USD 10,000 to 15,000.
- Order above your normal size. A supplier that handled 2,000 units may not have the lines or cash for 20,000.
- Long-term partnership. Before signing an annual supply agreement, exclusivity deal or tooling investment, know exactly who owns the factory and the molds.
- Compliance-sensitive products. Children's products, food contact items, electrical goods, cosmetics and anything sold to a retailer with a compliance code.
Types of China factory audit
The word "audit" covers several exercises, and the factory audit checklist below adapts to each. Pick the one that matches your risk, or combine them.
| Audit type | What it checks | Typical duration | Best for |
|---|---|---|---|
| Capability and capacity audit | Real factory or not, what it makes, how much, how fast | 0.5 to 1 day | Every new supplier |
| Quality system audit | Incoming QC, in-process controls, final inspection, calibration, records, ISO 9001 practice | 1 day | Technical products, repeat orders |
| Social compliance (BSCI or SMETA style) | Working hours, wages, child labor, health and safety, dormitories | 1 to 3 days | Retail and brand supply chains |
| Security (C-TPAT style) | Site access, container loading controls, cargo handling, personnel screening | 1 day | US importers in C-TPAT, high-value cargo |
| Remote video audit | Live walk-through of gate, floor, warehouse and QC on camera | 1 to 2 hours | First screening, small orders, travel restrictions |
For most importers, a one-day combined capability and quality system audit answers 90 percent of the questions. If you are still deciding between a manufacturer and a middleman, our comparison of a sourcing agent versus a trading company explains why the ownership question matters.
The full factory audit checklist
This is the structure our auditors follow. Each section gets a score from 0 to 10, and some items are automatic fails regardless of the total.
1. Legal and registration
- Business license: legal name, unified social credit code, registered address, legal representative, registered capital and business scope. The scope must include manufacturing, not only "trade".
- Registered capital: CNY 100,000 and a claimed 300 workers does not add up.
- Export license or customs registration if they claim to export directly. Otherwise they ship through an agent, which is fine, but know it.
- Address match: the license, the quotation letterhead, the Alibaba page and the gate you walk through should all agree. A mismatch usually means a trading company borrowing a factory.
2. Facilities
- Owned or rented premises, and the lease end date. Eight months left on a lease is a reorder risk.
- Total floor area and how it splits between production, warehouse, office and dormitory.
- Number of production lines and what each is currently running.
- Machine list with brand, model, year and condition. Ten-year-old machines can be fine; ten-year-old machines with no maintenance log are not.
3. Capacity
- Stated monthly output per product family, and the evidence: shift schedules, production boards, recent packing lists.
- Current utilization. A floor at 50 percent has room for you; a floor at 95 percent will push your order to the back.
- Lead time for your quantity, normal and peak season (September to December and before Chinese New Year).
- Headcount by department, permanent versus seasonal. Ask for the payroll count, not the brochure number.
4. Quality system
- Incoming material inspection: a procedure, a record and a quarantine area for rejected material.
- In-process QC: inspection points on the line, first-article approval, patrol inspection frequency.
- Final inspection: sampling plan, AQL used, defect classification, who signs off.
- Calibration: measuring tools labelled with calibration dates, and a schedule that is followed.
- Defect and complaint records for the last six months. Zero recorded defects means no system, not perfect quality.
- ISO 9001: real or bought. Ask for the internal audit plan, management review minutes and corrective action log. If none exist, the certificate was purchased.
5. Engineering and development
- Sample room with your product category's samples, revision labelled.
- Mold shop or mold storage with ownership tags. If you paid for tooling, your name should be on it.
- R&D staff count and drawing control. Can they modify a design, or only copy one?
6. Social compliance and safety
- Working hours and overtime records compared with time clock data.
- Age verification process and a spot check of the youngest-looking workers' ID copies.
- Fire exits unlocked and clear, extinguishers in date, evacuation plan posted, drill records.
- PPE in use where needed: gloves, eye and hearing protection, fume extraction.
- Dormitory and canteen conditions if provided.
7. Environmental
- Environmental permit for plating, painting, dyeing or injection molding.
- Waste handling: hazardous waste contracts, wastewater treatment, no leaking drums behind the building.
8. Financial stability
- Years at this site, bank reference letter, recent utility bills as a proxy for activity.
- Pending lawsuits or enforcement records on public credit databases.
9. Customers and references
- Two or three export customers in your market, and permission to contact one.
- Carton labels on the warehouse shelves showing real overseas customers.
Scoring the factory audit checklist and the go/no-go decision
We weight the nine sections and convert the total to a percentage. Legal, capacity and quality system carry the most weight; social compliance weighs more if the goods go to a retailer with a code of conduct.
| Score | Rating | Our recommendation |
|---|---|---|
| 85 to 100 | Approved | Proceed; standard pre-shipment inspection |
| 70 to 84 | Approved with conditions | Proceed; close the listed gaps before mass production, tighter inspection |
| 55 to 69 | Conditional | Trial order only, or re-audit after corrective actions |
| Below 55 | Rejected | Do not pay a deposit |
Some findings override the score entirely: child labor, a license that does not match the premises, locked fire exits, or refusal of access to the production floor. Any of these is an automatic no-go.
Red flags we see during audits
These patterns appear again and again, and each one has cost a buyer money. Our guide on how to avoid scams when buying from China covers the payment side; these are the physical signs.
- The showroom tour. A display room and a meeting table, then "the workshop is in another building" that is always unavailable.
- Idle, dusty machines. Equipment with no material loaded, no operators and a layer of dust is not in use. Real production, if any, is subcontracted.
- No QC records. A QC desk exists but the forms are blank, undated or all in the same handwriting from that morning.
- Certificates with the wrong company name. ISO, CE or BSCI certificates issued to a different legal entity, often the "sister factory" nobody can take you to.

Cost of a China factory audit and what the report contains
Expect USD 300 to 800 per audit day in 2026. The low end is a capability audit by a sourcing agent's team near their base; the high end is a certification body running a full social compliance protocol, or a remote factory requiring a flight and a hotel.
A useful report, delivered within two to three working days, contains:
- Executive summary with the overall score and a clear go, conditional or no-go recommendation.
- Copies of the business license, certificates and permits, with verification notes.
- Section-by-section findings against the checklist, each with evidence.
- Fifty to one hundred timestamped photos: gate, license, lines, machine plates, warehouse, QC area, fire exits.
- Machine list and capacity calculation.
- A corrective action list with deadlines, which becomes your pre-production checklist.
Factory audit versus product inspection
A factory audit happens before you order and evaluates the supplier as a company. A product inspection happens during or after production and evaluates a specific lot against your specification and an AQL sampling plan. One does not replace the other.
The right sequence is audit first, then a pre-production meeting, a during-production check for large orders, and finally a pre-shipment inspection before the balance payment. Our pre-shipment inspection checklist covers that last step. A good audit makes every later inspection cheaper, because the inspector already knows where to look.
Frequently asked questions
How much does a factory audit in China cost?
A standard factory audit in China costs roughly USD 300 to 800 per audit day in 2026, depending on the depth of the audit, the auditor's travel distance and whether you use a large certification body or a sourcing agent's team. Most capability and quality system audits take one day. A full social compliance audit for a factory with several hundred workers can take two to three days.
What is the difference between a factory audit and a product inspection?
A factory audit evaluates the supplier: legal status, equipment, capacity, quality system and working conditions. It answers the question "should we work with this factory?" A product inspection evaluates a specific order against your specification, usually right before shipment. It answers "is this batch good enough to ship?" Serious buyers do both, in that order.
Can a factory audit be done remotely?
Yes, a remote video audit is a workable first screen. The auditor joins a live video call, asks the factory to walk through the gate, production floor, warehouse and QC area in real time, and requests documents on camera. It cannot verify everything, since the factory controls the camera, but it is cheap and rules out many trading companies and ghost factories within an hour.
How do I know if a Chinese factory's ISO 9001 certificate is real?
Check that the company name and address on the certificate match the business license exactly, then verify the certificate number on the issuing body's website or on the CNCA database for Chinese certifiers. During the audit, ask to see the internal audit records, management review minutes and corrective action log that ISO 9001 requires. A bought certificate rarely comes with any of these.
Who should perform the factory audit?
Use someone independent of the supplier. Options are a third-party inspection company, a certification body for BSCI or SMETA-style audits, or your sourcing agent's own auditors. Never let the supplier arrange or pay for the audit, and never rely on a trading company's audit of its own factory. If you visit yourself, bring a local engineer who speaks the language and knows the product.
