TL;DR: A factory audit is a structured on-site or live-video check of a Chinese supplier before you send a deposit. It confirms the factory exists, can produce your order, has the quality systems it claims, and treats its workers fairly. This post walks through the six things a real audit covers, the red flags that should stop the wire, and how Bell Tower makes its Yiwu operation easy to verify.
You found a garden tool supplier online. The photos look good. The WeChat replies are fast. The quote is 20% below anyone else. Before that deposit lands, one question matters more than price: is this a real factory that can actually make and ship what you ordered? A proper china factory audit answers that. It is a short, structured check of a supplier’s premises, paperwork, and processes, run before any money moves. A good audit costs a few hundred dollars. A missed one can cost the whole order. This guide covers what an audit checks, what to ask for, and the signals that should keep your finger off the “send” button.
What a Factory Audit Actually Is (and What It Isn’t)
Three checks get confused in sourcing conversations. They happen at different times and answer different questions.
- Supplier verification is a desk check. It confirms the company legally exists and is registered as a manufacturer, not a trader in a rented office.
- Factory audit is the on-site or live-video evaluation of capacity, quality systems, and compliance. This is the one you run before your first significant order.
- Pre-shipment inspection happens later, on finished goods, against an agreed sample plan. It answers “does this shipment match the spec?”
Serious buyers do all three. The audit is the one that protects the deposit.
The Six Things a Real Audit Checks On-Site
Reputable auditors work from a checklist. A useful audit for a garden tool supplier covers:
| Audit domain | What the auditor verifies |
|---|---|
| Legal & commercial | Business license, export licence, ownership (manufacturer vs. trader), tax status |
| Production capability | Workshops, machinery, staff count, monthly capacity, output for your category |
| Quality management | Incoming (IQC), in-process (IPQC), and final (OQC) inspection records; defect handling |
| R&D and sampling | Sample room, tooling, ability to run OEM or private label work |
| Compliance & certifications | CE, ISO 9001, SGS reports |
| Social & environmental | Working hours, fire safety, waste handling |
An audit that skips any of these six is a tour, not an audit.
Documents to Request Before the Auditor Arrives
Around half the audit is done on paper. Ask the supplier for these upfront:
- Business licence in Chinese, plus the English translation
- Export licence and customs registration number
- Certifications you plan to rely on (CE, ISO 9001, SGS)
- A short factory video walk-through
If any of these take more than 48 hours to produce, that itself is a signal.
Red Flags That Should Stop the Deposit
Some findings are recoverable with a fix and a re-check. Others are hard stops. Treat any of these as reasons to pause the wire:
- The registered address does not match the workshop
- Certifications are photocopies with no verifiable issuing-body reference
- The supplier declines a live video walk-through
- Workshop photos show equipment that could not produce your category
- The auditor finds no incoming-material or in-process inspection records
- Payment terms suddenly change to 100% before production
Who Should Run the Audit
You have four practical options, each with a different cost and depth:
- Global third-party firm (SGS, QIMA,): the most thorough, typically the highest cost. Best for first orders over $20,000.
- Regional inspection firm: mid-sized specialists at a lower price point, often stronger on niche categories.
- Sourcing agent: useful if you already work with one, but confirm they are independent from the factory.
- In-person visit: if you or a team member is already in China for the Canton Fair or Spoga+Gafa, a live walk-through is an option.
Never rely on the supplier’s own audit report. It is not an audit if the audited party wrote it.

Wrap-Up
A factory audit is usually cheap. It costs a fraction of one order and protects the whole relationship. Confirm the paperwork, book a real on-site or live-video check, watch for the red flags above, and only wire the deposit when you have your answer in writing.
