Factory Audit China

Factory Audit in China: Verify Supplier Capability before You Commit

You found a supplier, liked the sample, and the quote looks workable. The next step is often a deposit. Before that money leaves, you need one practical answer: is this a real factory that can make your product at the volume you need, or a trading office that will pass the order to someone else?

QIS runs independent factory and supplier audits across China for importers, ecommerce brands, and Amazon FBA sellers. An auditor visits the stated production site, checks business identity against what you were told, reviews equipment and capacity, looks at basic quality-control practice, and writes a risk summary. You use that summary to approve the supplier, place a trial order, request corrective action, or reject the site. If you already have a supplier address and a deposit date, book a factory audit. We will confirm scope, city, and quotation.

This page covers factory and supplier audit: what it is, when to book (including before deposit), what is checked, how the visit runs, what the report contains, and how it differs from product inspection. Finished-lot quality belongs on pre-shipment inspection. Amazon FBA label and packing procedure depth lives on Amazon FBA inspection in China.

What is a factory audit?

What Is a Factory Audit?

A factory audit (also called a supplier audit or supplier verification visit) is an on-site review of the supplier you plan to pay. At the factory or claimed production address in China, QIS checks whether the entity matches the site, whether manufacturing activity fits your product category, whether equipment and lines can support your order size, and how incoming materials, in-process checks, and final inspection are handled.

A factory audit is not a laboratory test. It is not a product inspection of your purchase order. It is not a certificate. It does not approve the supplier for Amazon, for customs, or for any standards body. It is a documented risk review with photos and a clear recommendation. You decide the next commercial step.

Use an audit when the open question is about the supplier. Use product inspection when the open question is about the goods on a specific order.

On-site checks

What QIS Checks during a Factory Audit

Every visit follows the scope you book. A typical China factory audit covers the areas that most often explain deposit loss, missed ship dates, and good samples that fail in mass production.

Supplier identity and site match

Confirm the business identity, factory location, contact person, and production site against the quote and chat thread. Flag mismatches: office-only addresses presented as factories, nameplates that do not match invoices, or production that does not match the product you were sold.

Production capability and capacity

Review equipment, production lines, rough capacity, product experience, and how orders are planned. Note subcontracting risk when key processes sit outside the site you are paying. The practical question: can this site handle your trial and your planned volume without silent outsourcing?

Quality control process

Look at incoming material control, in-process checks, final inspection habits, defect handling, and whether basic records exist. Weak or missing QC process is a common reason good samples turn into bad mass lots.

Sourcing risk summary

Close with a clear recommendation: supplier approval, trial order only, corrective action before deposit, or reject. The report is written so you can forward findings to the supplier as a to-do list when that helps.

For ongoing defect taxonomy, written specs, and corrective-action follow-up across many lots, use supplier quality control. A one-day audit is not a full quality-engineering program.

Process

How QIS Conducts a Factory Audit in China

Step What QIS does Buyer decision value
1. Booking review Reviews supplier address, product category, order intent, audit depth, and any documents you already have. Confirms scope and quotation before travel.
2. On-site visit Visits the stated production site; walks production areas; checks identity cues, equipment, and basic QC practice. Sees the site you are about to fund.
3. Evidence capture Records photos and notes on facility, lines, process gaps, and mismatches vs supplier claims. Gives you shareable proof, not a chat claim.
4. Risk conclusion Summarizes findings and recommends approve, trial, corrective action, or reject. Supports deposit, PO size, and supplier-choice decisions.
5. Report delivery Issues a photo-backed audit report you can keep on file and send to the supplier when needed. Documents the decision basis.

Exact report timing depends on audit depth and travel. QIS confirms delivery expectations when the quotation is issued.

Factory Audit vs Product Inspection

Topic Factory / supplier audit Product inspection (e.g. PSI)
Main question Can this supplier make my product, and are they who they say they are? Do these finished goods match my order?
Timing Often before deposit or before scaling When production is complete and mostly packed
Object of review Site, identity, capacity, QC system Sampled units and cartons from your lot
Output Risk recommendation on the supplier PASS / FAIL / HOLD style result on the shipment
Typical next step Approve, trial, fix process, or switch supplier Pay balance, rework, hold, or re-inspect
Starting Price (This Site) From $199 on this page From $129 on the PSI page

Many new-supplier programs use both: audit first, then inspection on the trial or first mass order. Sampling mechanics for inspections are on the AQL sampling page.

Deliverables

What the Client Receives

A standard QIS factory audit report is written for a sourcing decision:

QIS factory audit notes and photo evidence at a China supplier site

The report documents what was observed against the booked scope. It is not a product certification. It does not replace laboratory testing where your market requires it.

Prep checklist

What to Prepare before the Auditor Arrives

Send these before booking confirmation when you have them:

  1. Supplier company name (English and Chinese if available).
  2. Full factory / production address and a map pin or landmark notes.
  3. Contact person and phone / WeChat for on-site access.
  4. Product category, target order quantity, and whether a deposit date is already set.
  5. Quote, business card, Alibaba / website profile, or license copies you already collected.
  6. Any known risks (suspected trading company, past quality failures, subcontracting claims).

Access delays cost a day. Confirm the factory knows an independent auditor is coming and that production areas can be walked.

FAQ

Factory Audit Questions

Should I audit a factory before paying a deposit?

For a new supplier or a large order, yes. An on-site audit before deposit payment reduces the risk of paying a weak manufacturer, a middleman, or a site that cannot produce the agreed product. For a tiny reorder with a proven factory, inspection timing may matter more than a fresh audit.

Can QIS verify whether a Chinese supplier is a real factory?

Yes. QIS can visit the supplier site and review business identity, production area, equipment, workers, quality-control process, and whether manufacturing activity matches the product category.

Is a factory audit the same as product inspection?

No. Factory audit checks supplier capability and risk. Product inspection checks the actual goods in your order. For new suppliers, both are useful at different stages.

How much does a factory audit cost in China?

QIS standard factory audit services start From $199. Final price depends on city, audit depth, and product category. QIS confirms the quotation before the visit is scheduled.

When should Amazon sellers audit a supplier?

Before paying a deposit, before scaling order volume, or after repeated quality problems that suggest weak process control. FBA label and packing checks still need an inspection visit. See Amazon FBA inspection in China.

Does a factory audit replace laboratory testing or certification?

No. An audit is a site and process risk review. It does not issue product certificates and does not replace lab tests required by your destination market.

What happens if the audit finds high risk?

You can delay or reduce the deposit, request corrective action, run a smaller trial order, switch supplier, or walk away. QIS documents findings. You keep the commercial decision.

Can I combine audit with later inspections on the same supplier?

Yes. A common path is audit, then a trial order with during-production inspection or pre-shipment inspection, then loading check when the first container ships.
