If you are attending the Canton Fair for the first time, you probably assume that finding good suppliers is the hard part. It is not. The real challenge is filtering out the wrong ones before you waste months on poor‑fit relationships.
A booth with attractive samples and polished sales pitches can be misleading. But impressive booth displays do not equal reliable suppliers. Up to 40% of exhibitors at the fair are trading companies or middlemen, adding a markup of 10‑30% to unit prices without your knowledge.
Many first‑time buyers spend two or three weeks emailing a supplier they met at the booth, only to discover later that it was a pure trading company with no workshop of its own.
This Canton Fair Guide is not about what the fair is. It is about what to ask once you are standing in front of a supplier’s booth. The difference between landing a reliable manufacturing partner and making costly mistakes often comes down to the questions you ask before walking away. The right questions reveal production capacity, expose middlemen, and separate serious factories from casual vendors.
The First Filter: Factory vs. Trading Company
The first question is not about price — it is about identity. Up to 40% of exhibitors at the fair are middlemen, not manufacturers. They rent booths and display samples while posing as factories. Your job is to spot them.
Use this table to quickly judge each supplier’s reply during your booth meeting.
| Question | ✅ What to look for | ⚠️ Red flag |
|---|---|---|
| “Are you a factory or a trading company?” | Confident answer about their factory location and size | Hesitation, vague answer, or “we have our own factory” without details |
| “Can we visit your factory next week?” | Immediate agreement and specific address | “We need to check with the factory first” |
| “What percentage of your output is manufactured in-house?” | Clear percentage (80% or higher) | Evasive answer or “we work with many partner factories” |
A real manufacturer answers these questions clearly. A trading company hedges. At Sourcingyuan, we have seen buyers walk past red flags simply because they did not ask these three questions. They are not difficult questions—they are just questions most buyers skip.

Production and Capacity: What They Can Actually Deliver
Once you confirm they are a factory, your next check is whether they have enough capacity for your order. Great samples mean nothing if their production lines cannot handle bulk orders.
Use this table to evaluate whether the factory can realistically handle your order volume and timeline.
| Question | ✅ What to look for | ⚠️ Red flag |
|---|---|---|
| “What is your monthly production capacity?” | Exact concrete figures, not vague ranges | “We can produce whatever quantity you need” |
| “What is your standard production lead time?” | Specific timelines (e.g. 30‑45 days) | Vague replies such as “it depends” |
| “How do you handle capacity pressure during peak seasons?” | Clear plans for scaling production | Only states “we have enough capacity” with no supporting details |
| “Do you have machinery for [specific process]?” | Confirms in‑house equipment and capability | “We can outsource that part” |
Factories that know their production numbers operate professionally. Vague answers point to either a trading company or poor control over production schedules. From our years working with buyers in Guangzhou, factories that state clear capacity figures tend to deliver on‑time more consistently.
Why production capacity matters for new buyers
Many new overseas buyers only focus on sample quality. Perfect samples do not guarantee reliable bulk‑order delivery. Even great samples cannot prevent shipment delays and failed orders when capacity is insufficient.
Quality Control and Compliance
Quality is not only checked at the end of production — it is built throughout the whole manufacturing process. Serious suppliers maintain formal procedures for handling defects and quality complaints.
Use this table to assess whether the supplier takes quality control seriously.
| Question | ✅ What to look for | ⚠️ Red flag |
|---|---|---|
| “What quality certifications do you hold?” | Names concrete certifications (ISO, BSCI, etc.) | Cannot specify names, only shows photocopied documents |
| “Do you have test reports for my target market?” | Can provide relevant test documentation | “We can get those for you later” |
| “What does your internal QC process look like?” | Describes inspection steps across production stages | Only says “we check everything before shipment” with no process details |
| “Can we use third‑party inspection services?” | Welcomes independent inspectors | Reluctant, claims “our own QC is enough” |
Pro tip: If they claim certifications, ask for certificate numbers for verification. Trading companies often show borrowed certificates. Real factory certificates are traceable and valid.
Third‑party inspection tips
Independent inspection is one of the safest ways to reduce quality risk. Reliable factories accept third‑party inspectors without push‑back. Avoid suppliers who refuse external quality checks.
MOQ, Customization, and Payment Terms
These practical commercial details determine whether a supplier fits your business, and reveal hidden risks.
Use this table to confirm commercial terms before moving forward with any supplier.
| Question | ✅ What to look for | ⚠️ Red flag |
|---|---|---|
| “What is your Minimum Order Quantity (MOQ)?” | Clear figures with flexibility for trial orders | Pressures you into large‑volume orders immediately |
| “Do you offer OEM or ODM customization?” | Clearly explains their customization workflow | Agrees verbally but cannot walk you through the process |
| “Can you provide samples before ordering?” | Confirms sample availability (sample fees may apply) | Unwilling to supply samples |
| “What are your standard payment terms?” | Clear terms (e.g. 30% deposit, 70% before shipment) | Demands 100% advance payment |
Why MOQ matters: Lower MOQ shows flexibility and openness to new buyers. High MOQ often means the factory mainly serves large‑volume clients; this is not automatically bad but requires extra attention.
Red flags for risky payment terms
Proceed with caution if a supplier requests 100% advance payment. This is highly unusual for normal manufacturing orders sourced from the Canton Fair. Stick to industry‑standard deposit‑based payment structures.
The 5 High‑Impact Questions for Face‑to‑Face Evaluation
These five questions help you decide whether a supplier deserves further follow‑up. These are not small‑talk questions — they uncover critical facts to separate serious partners from time‑wasters.
Use this table as your final on‑site screening tool before deciding who to shortlist.
| Question | Why it matters | ✅ Green signal | ⚠️ Red flag |
|---|---|---|---|
| “Have you supplied major well‑known brands?” | Checks real‑world track record | Names brands and can provide supporting proof | Hesitant, cannot give concrete examples |
| “What is your MOQ?” | Tests business flexibility | Accepts small‑batch trial orders | Constantly pushes large‑volume orders |
| “How do you handle defective‑product issues?” | Evaluates after‑sales accountability | Mentions corrective actions or replacement solutions | Avoids the question with vague replies |
| “Can we tour your factory production lines?” | Tests transparency | Shares details and arranges factory visits | Makes excuses to decline |
| “What are your lead times during peak seasons?” | Checks capacity planning | Gives clear timelines and notes peak‑season adjustments | Inconsistent or overly optimistic estimates |
On‑site quick‑reference checklist

| Category | Questions to ask |
|---|---|
| Identity | Are you a factory or trading company? Where is your facility? Can we visit next week? |

The Bottom Line
The Canton Fair is one of the world’s most efficient sourcing events — but only if you ask the right questions. Distinguishing reliable factories from middlemen often depends on one conversation. Real manufacturers know their numbers; middlemen give vague guesses.
Use this Canton Fair Guide to screen suppliers quickly. Ask about production capacity, quality control, MOQ and payment terms. Use the five high‑impact questions to test transparency. Take photos of booth samples and business cards. Remember: real sourcing work begins after the fair, with factory visits, sample testing and formal follow‑up.
