Factory Audit in China: What It Checks, What It Costs and When to Order One

Most expensive sourcing mistakes happen before the first purchase order: paying a trading company that claimed to be a factory, tooling up with a plant that subcontracts your product, or discovering after a retailer's audit that your supplier fails on working hours. A factory audit is the tool that catches these before money moves. This guide explains the audit types, what an auditor checks in a day on site, published costs in China, how to order one, and what the report can and cannot tell you.

Audit vs inspection: two different questions#

A factory audit answers "who is this supplier and can they do this?" It looks at the company, the buildings, the machines, the people and the management systems. It happens before you order, or before you scale.

An inspection answers "are these goods right?" It samples a specific batch against your specification and an AQL. It happens during or after production, before the balance payment. See the pre-shipment inspection checklist.

Buyers often order an inspection and skip the audit, then find that the goods passed but came from a different factory than the one on the contract. The audit is what ties the legal entity, the premises and the production lines together.

The main audit types#

Most first-time buyers need the supplier qualification audit, sometimes combined with a light quality-system review in the same visit. Social compliance comes in when a retailer or platform asks for it; the factory then often already holds a SMETA or BSCI report you can request through the scheme.

What the auditor checks on site#

A one-day supplier qualification audit by a Chinese inspection company usually covers the following. Ask for the checklist before booking so you can add product-specific items.

1. Legal identity. Business licence (营业执照), unified social credit code, registered address and legal representative, compared against the premises visited and the company you are contracting with. The auditor should also check the public record on gsxt.gov.cn for the business scope (does it include manufacturing verbs for your product?) and any abnormal-operation listings.
2. Premises and ownership. Site area, building count, lease or ownership documents, and whether the production area matches what the sales team showed you on video.
3. Production capability. Production lines, key machines with model and age, number of workers per line, shifts, current utilisation, in-house versus subcontracted processes. This is where "we are a factory" claims fall apart: a company with assembly benches but no moulding, cutting or sewing lines for your product is buying components or finished goods elsewhere.
4. Capacity. Monthly output for your product type, order book, and lead-time reality. Useful when you plan to grow the order.
5. Quality control. Incoming material inspection, in-process checks, final inspection, defect records, calibration of measuring tools, handling of customer complaints. Photos of actual records, not just procedures.
6. Certifications and test reports. Copies of ISO, product certificates (CE, FCC, UKCA, CPC and the like) and lab reports, with issuer and expiry noted so you can verify them. See product certifications explained.
7. Workforce and basic social indicators. Headcount, labour contracts, age verification practice, fire exits and extinguishers, personal protective equipment. A qualification audit flags obvious issues; a full social compliance audit goes much deeper.
8. Export experience. Markets served, main customers by region (named only if the factory agrees), export documents handled in-house or by an agent.
9. Financial and reputation signals. Years in operation, registered capital, litigation records, major customers, Alibaba or 1688 store history.

The report ends with a score or rating per section and an overall verdict, typically with photos of every area visited and copies of key documents.

What a factory audit costs in China#

Inspection companies price audits per man-day, meaning one auditor on site for one day plus the report. Published figures we reviewed in October 2026:

Rules of thumb used by the industry: one man-day for a factory under about 500 workers, two for larger sites or for a combined quality and social scope. Factories far from major cities may add travel surcharges. A full SMETA or amfori BSCI audit normally runs two to three man-days plus scheme fees.

Set that against what it protects. A USD 300–600 audit before a USD 20,000 first order or a USD 5,000 mould is cheap insurance; before a USD 2,000 sample order it is not, and a video tour plus a licence check is the proportionate step.

When to order an audit#

Order one when:

• The supplier is new and the first order, tooling or your brand's exposure is worth more than the audit fee.
• The product is custom or private label and you need to know the lines are in-house.
• A retailer, marketplace or your own compliance policy requires a social or security audit.
• Something does not add up: the licence address differs from the "factory" you were shown, the quoted capacity seems too high, or the company name on the invoice keeps changing.
• You are about to move from samples to a container.

You can usually skip it when:

• You buy stock items in small quantities through a platform with buyer protection and inspect the goods before shipment.
• A current scheme audit report (SMETA, BSCI) already exists and the scheme lets you access it.
• The supplier is a trading company you have chosen knowingly for low MOQ; audit the trading company's licence and bank account instead, and inspect the goods.

How to order a factory audit#

1. Collect the supplier's details yourself: Chinese company name, licence copy, factory address, contact person. Do not let the supplier book the auditor.
2. Choose scope and standard. Supplier qualification only, or with a quality-system section, or a scheme audit. Send the inspection company your product spec and any retailer requirements so they add the relevant checks.
3. Book with an independent company that you pay directly. Most publish online booking, need three to five working days' notice, and deliver the report within one to two working days after the visit.
4. Tell the supplier it is a standard part of your process. Honest factories expect audits from serious buyers; a refusal or endless rescheduling is itself a result.
5. Read the report for mismatches, not just the score. Does the licence name match your contract? Are the production lines for your product on site? Do the certificate numbers verify on the issuer's site? Note the date; an audit is a snapshot.
6. Decide and record. Approve, approve with conditions (for example, named subcontractor allowed for one process), or reject. Keep the report with the supplier file; retailers and insurers may ask for it later.

Reading the report: what a pass does not mean#

A good audit tells you the factory exists, is the entity you are paying, has the equipment and a functioning system on the day. It does not guarantee that your order will be produced on those lines, that the workers you saw will make it, or that quality will hold under a rush. Three habits close that gap:

• Write the audited factory address into the purchase order as the place of production, and require written approval for any subcontracting.
• Combine the audit with a during-production or pre-shipment inspection on the first order.
• Re-audit when something changes: new product category, a move to a new site, a sharp increase in order size, or a change of legal entity.
