Before You Arrive: Pre-Visit Preparation
A factory visit without preparation is tourism. The goal isn't just to see the facility — it's to gather specific, structured evidence that either confirms or contradicts what the factory has told you. Before you book your flight, your preparation should include several key steps.
Request a factory profile package. Ask the factory to send you their business license, export license, ISO certification (if any), recent third-party audit reports, a current employee count, and photos of their production lines before you arrive. Inconsistencies between this documentation and what you observe on-site are significant red flags.
Brief your interpreter. If you're working with a local interpreter, brief them on the specific technical questions you'll be asking. A general interpreter who doesn't know the difference between a silicone compression mold and an injection mold will struggle to accurately translate answers from a production manager. Aqualora Distribution's Asia Pacific team often accompanies buyers on factory visits for this reason — on-ground expertise changes what you're able to learn from an audit.
Prepare your checklist in advance. Print it. The factory visit moves quickly, and you will not remember everything you wanted to ask unless it's in front of you in structured form.
The Factory Floor Audit Checklist
When you arrive, you're looking for evidence across six dimensions: production capability, quality control systems, workforce, equipment, documentation, and environment. Work through these systematically.
1. Production Capability
- Is the production line you're seeing actually active, or does it look staged? Ask to see the current production order in progress.
- What is their actual monthly production capacity for your product type? Ask for a specific number, not a range.
- Can they show you products currently in process for other customers? (They may decline for confidentiality reasons — that's acceptable. But genuine manufacturers usually have active orders.)
- For OEM manufacturing specifically: do they have a dedicated area for your product category, or are they cross-running multiple unrelated product types on the same equipment?
- What is their lead time from order confirmation to loading? How does this compare to what they quoted you?
2. Quality Assurance Systems
- Is there a dedicated QC inspection station on the production line, or is quality checking done informally?
- Where is the incoming materials inspection station? Can you see it operating?
- Ask to see their defect log for the past month. A factory that doesn't track defects doesn't manage quality.
- How are finished goods inspected before packing? What is their internal AQL standard?
- Is their testing laboratory on-site or outsourced? If outsourced, which labs do they use?
3. Workforce and Management
- How many production workers are on-site today? How does this compare to their stated workforce?
- Is the production manager available to speak with you directly? The person giving you the tour may not be the person running the floor.
- What is worker turnover like? High turnover is a consistent quality risk — training new workers takes time and introduces variation.
- Ask to speak briefly with one or two line workers (through your interpreter). Their answers about how they check their work will tell you more than any management presentation.
Important: Request to see the factory unannounced areas — storage rooms, loading docks, raw materials storage. A factory confident in their operation will show you everything. Resistance to showing you the full facility — especially areas "under renovation" or "off limits today" — warrants serious follow-up.
4. Equipment and Technology
- Is the equipment appropriate for your product's manufacturing requirements? Look for wear, maintenance, and age.
- Are machines calibrated and maintained? Ask to see maintenance records.
- For precision products: do they have measurement and testing instruments? Are they calibrated?
- What tooling do they own versus contract out? For products requiring complex molds, proprietary tooling is a significant investment — factories that have it are more serious manufacturing partners.
5. Environmental and Labor Compliance
- Are workers using appropriate personal protective equipment for their task?
- Is the factory environment reasonable — adequate lighting, ventilation, and workstation organization?
- Look for fire safety compliance: sprinklers, extinguishers, clear exit paths.
- Is there evidence of child labor? This is rare at legitimate factories but remains a concern in some subcontracting networks.
Questions That Separate Real Factories from Trading Companies
Trading companies — middlemen who source from actual manufacturers and mark up the goods — are common in China's export ecosystem. They're not inherently bad; sometimes they offer value. But if you believe you're dealing directly with a manufacturer and you're actually dealing with a trading company, you're losing pricing visibility, control over quality, and leverage in disputes.
These questions, asked directly and observing the response carefully, will usually reveal the truth:
"Can you show me the mold for this product?" — If they manufacture the product, they own or have access to the tooling. A trading company will deflect, say the mold is at a "partner facility," or give a vague answer.
"What is your MOQ per production run, and how many runs do you schedule per month?" — Real manufacturers will have specific answers tied to their line capacity. Trading companies often give inconsistent answers because they're aggregating orders across multiple actual factories.
"Can I see last month's production schedule?" — Genuine factories have production management documents. If this request is met with confusion or deflection, it's a signal.
"Who is your raw materials supplier for [specific material], and can I see a recent delivery receipt?" — Manufacturers receive raw materials. Trading companies receive finished goods. The documentation they have on hand will tell you which one you're looking at.
Red Flags You Cannot Ignore
Some warning signs are subtle. Others are unmistakable. Here are the ones that should immediately elevate your due diligence or cause you to reconsider the relationship entirely.
Red Flag — The Showroom Factory: The front office is immaculate, the sample room is impressive, but the production area is small relative to claimed capacity, or appears to be a general-purpose space that could produce almost anything. Legitimate high-volume manufacturers look lived-in: tooling marks on floors, organized inventory of in-process materials, workers focused on their stations rather than watching you.
Red Flag — The Wrong Facility: The address on the business license doesn't match the facility you're visiting. This is a serious compliance issue — it may indicate subcontracting to uncertified facilities, which is one of the most common sources of quality failures in Chinese manufacturing.
Red Flag — No Evidence of Incoming QC: A factory with no incoming materials inspection has no way to catch defects introduced by their raw materials supplier. This is especially dangerous for food-grade products, electrical components, and anything with regulatory compliance requirements, where material quality directly affects product testing outcomes.
When Aqualora Distribution's sourcing team evaluates potential manufacturing partners in Asia Pacific, factory audits are a standard part of the vetting protocol. Buyers who work with us don't need to fly to Guangdong to perform this due diligence — our on-ground team does it systematically, with standardized audit scorecards that have been refined across hundreds of factory evaluations.
After the Visit: Follow-Up and Documentation
The factory visit generates evidence. What you do with that evidence determines whether it was worth the trip.
Write your audit notes within 24 hours. Details fade quickly. Immediately after the visit, record your observations against each checklist item while they're fresh. Note specific things you saw, specific questions you asked, and specific answers you received.
Request any outstanding documentation. Items they didn't have on hand during the visit — calibration records, ISO certificates, test reports — should be formally requested in writing with a delivery deadline.
Share your findings with your team. Factory audit findings should inform your quality assurance protocol for this supplier, your sampling requirements, and your pre-shipment inspection plan. A factory with strong in-house QC systems may require less aggressive third-party inspection. A factory with gaps in their QC process needs compensating controls.
Decide objectively. The sunk cost of a long factory trip should not influence your decision. If the audit reveals that the factory is not the right fit — whether it's capability, compliance, or the trading company discovery — the cost of building a supply chain on a weak foundation is always higher.
Key Takeaways
- Prepare a structured audit checklist before you arrive — factory visits move fast and undirected observation misses critical information.
- Evaluate six dimensions: production capability, quality assurance systems, workforce, equipment, documentation, and environmental compliance.
- Use specific diagnostic questions to distinguish real manufacturers from trading companies — ask about tooling, production schedules, and raw materials sourcing.
- Request access to areas beyond the showroom; resistance to full-facility access is a significant red flag.
- Document all findings within 24 hours and use them to calibrate your quality control and inspection protocols for that supplier.
- Consider working with an on-ground Asia Pacific partner like Aqualora Distribution who can conduct factory audits on your behalf before you commit to a supplier relationship.
