5 Red Flags When Choosing a Chinese Supplier

Every year, thousands of overseas buyers lose money to unreliable Chinese suppliers. The good news: most problems are avoidable if you know what to look for. After 10 years working inside Chinese factories, here are the red flags I watch for — and what to do instead.

Red Flag #1: They Won't Share Their Factory Address

A legitimate factory has nothing to hide. If a supplier dodges questions about their location, refuses to allow visits, or only meets you at a hotel or trade show booth — they're likely a trading company pretending to be a factory.

What to do instead:

Ask for their business license (营业执照) which includes their registered address. Cross-reference it on Google Maps or Baidu Maps. A real factory will have an industrial park address, not a residential or office building.

Red Flag #2: Prices Are Suspiciously Low

If one supplier quotes 40% below everyone else, something is wrong. They're either:

• Using inferior materials (recycled steel instead of virgin, thinner gauge)
• Skipping quality control steps
• Planning to raise the price after you've paid the deposit
• A scam operation that won't deliver at all

What to do instead:

Get 3-5 quotes for the same product. The realistic price range becomes obvious. If someone is far below that range, ask them specifically what materials and processes they use — and get it in writing.

Red Flag #3: No Quality Control Process

Ask any supplier: "What is your quality control process?" A reliable factory will describe specific steps:

• Incoming material inspection
• In-process checks at key stages
• Final inspection with AQL sampling
• Pre-shipment inspection

If they just say "don't worry, our quality is good" — worry.

What to do instead:

Request their QC checklist or inspection reports from previous orders. If they can't produce any documentation, they don't have a real QC system.

Red Flag #4: They Push for 100% Payment Upfront

Standard payment terms in Chinese manufacturing are:

• 30% deposit + 70% before shipment (most common)
• 30/30/40 (deposit / after production / after inspection)
• Letter of Credit for large orders

Any factory demanding full payment before production starts is either desperate for cash (bad sign) or planning to disappear with your money.

What to do instead:

Insist on standard terms. Use PayPal for orders under $5,000 (180-day buyer protection). For larger orders, use a trade assurance platform or bank transfer with milestone payments.

Red Flag #5: They Claim to Make Everything

"Yes, we can make that too!" is the most dangerous phrase in Chinese sourcing. A factory that claims to produce kitchen knives, CNC parts, textiles, AND electronics is not a factory — it's a trading company that will outsource your order to whoever is cheapest.

What to do instead:

Ask what their TOP 3 products are. Ask what percentage of their revenue comes from those products. A real factory specializes. They'll proudly tell you they've been making one category of products for 15 years.

The Bigger Picture

These red flags share a common theme: lack of transparency. Reliable factories are proud of what they do. They'll show you their production lines, share their certifications, introduce you to their QC team, and give you references.

If a supplier makes you feel like you're pulling teeth to get basic information — trust that instinct and move on.
