How to Vet a Chinese Supplier: A 30-Minute Checklist for New Importers

Last updated: May 2026 · 10 min read

Most first-time importers lose money in one of two ways: they pay too much, or they pick the wrong supplier.

Paying too much is fixable. You negotiate better next time, you find a different source, you adjust your pricing. But picking the wrong supplier — one who ships defective goods, disappears after payment, or sends something completely different from what you ordered — can kill a product launch before it starts.

The good news: many high-risk suppliers show warning signs before you spend a single dollar. You just need to know what to look for, and where.

This guide walks you through a 30-minute supplier vetting process you can run on any Alibaba or 1688 listing before you make first contact.

Why Vetting the Supplier Matters More Than Vetting the Product

New importers focus on the product: the photos, the price, the specifications. Experienced importers focus on the supplier first.

Here’s why: the same product can be manufactured well or badly, shipped on time or late, packed carefully or carelessly — depending entirely on who makes it. Two suppliers can list an identical product at identical prices. One runs a professional operation with eight years of export experience. The other registered their business six months ago and has twelve completed orders.

You cannot tell them apart from the product listing. You can tell them apart from the supplier data.

Spend 30 minutes on supplier vetting before your first contact. It costs you nothing. It can save you a great deal.

The 30-Minute Supplier Vetting Checklist

Step 1: Check Registration Age (3 minutes)

What to look for: How long has this supplier been registered on the platform?

On Alibaba, this is shown on the supplier’s store page as “Years on Alibaba” or similar. On 1688, look for the registration date in the store information section.

As a rough guide:

Less than 1 year: Higher risk. Not automatically a scammer, but unproven.
1–3 years: Acceptable for small test orders with careful vetting.
3+ years: Generally a positive signal. Long enough to build a track record.

Important: Registration age is only one signal. A three-year-old supplier can still deliver poor quality, and a newer supplier is not automatically unreliable. Use this check together with transaction history, reviews, communication, and samples — never alone.

Red flag: A supplier with a very recent registration date who is offering unusually low prices or high-value products.

Step 2: Check Transaction Volume and Activity (5 minutes)

What to look for: How many orders has this supplier completed? Are they still active?

On Alibaba, look for the number of transactions and transaction value range on the store page. On 1688, look for order volume indicators and recent activity.

What it means:

Zero or very few orders: Less data to work with. Possible that a good factory operates mostly offline, but no platform track record to evaluate.
Consistent volume over multiple years: A positive signal of an ongoing business.
Significant drop in recent activity: Worth noting. Could indicate quality problems or a shift in their business model.

Red flag: A supplier claiming to be a large manufacturer with very low or zero platform transaction history.

Step 3: Read the Reviews — Carefully (5 minutes)

What to look for: Not just the star rating, but the content of reviews, when they were left, and whether the supplier responded to negative feedback.

A 4.8-star rating with 200 reviews over three years is more meaningful than a 5.0-star rating with 4 reviews. Consistent reviews across time, product categories, and different buyers indicate a real track record.

Read negative reviews specifically. How did the supplier respond? A supplier who blames the buyer, refuses to engage, or has multiple complaints about the same issue is showing you how they handle problems.

Red flags: All reviews posted within a short time window • No responses to negative feedback • Multiple reviews mentioning the same problem (late delivery, quality not matching photos, unresponsive after payment) • Reviews that sound generic or templated.

Step 4: Verify What Type of Seller They Are (5 minutes)

What to look for: Is this supplier a factory (manufacturer) or a trading company?

A factory manufactures the product directly. They have more control over quality and production timelines, and their prices are typically lower. A trading company sources from factories and resells. They may work with multiple suppliers across different product categories.

A factory is not always the better choice. For many new importers, a professional trading company can actually be easier to work with — they often communicate in better English, handle smaller orders more flexibly, and coordinate across product details. The key is not to avoid trading companies. The key is to know which one you’re dealing with, so you understand the supply chain behind your order.

How to check on Alibaba:

Look for “Manufacturer” or “Trading Company” in the business type field
A factory typically specializes in a narrow product category; a trading company often lists products across many unrelated categories
Look at factory photos, production certifications, and equipment

How to check on 1688:

Look for “厂家” (factory) or “商家” (merchant/trader) indicators
Check whether they list one focused category or many different ones

Red flag: A supplier claiming to be a factory but listing products across wildly unrelated categories with no apparent specialization.

Step 5: Check Certifications (3 minutes)

What to look for: Do they have certifications relevant to your product and target market?

Common certifications to look for:

ISO 9001 — General quality management system
CE — Required for many products sold in the EU
FCC — Required for many electronics sold in the US
BSCI / SEDEX — Social compliance audits
SGS / Bureau Veritas / Intertek — Third-party inspection reports

Important: Certification requirements vary significantly by product type and destination country. A certificate that matters for one category may be completely irrelevant for another. Do not treat certifications as proof that a product is legal to import or sell in your market. Use them as one risk signal, then verify the specific compliance requirements for your exact product category before placing any order.

If certifications are claimed but not documented, ask for the actual certificates — not photos, actual documents with certificate numbers you can verify.

Red flag: A supplier claiming certifications they cannot produce documentation for.

Step 6: Check Response Rate and Speed (2 minutes)

What to look for: Alibaba shows a response rate and average response time on supplier profiles.

As a rough guide:

90%+: Strong signal
70–90%: May be acceptable
Below 70%: Deserves caution, especially for a first-time relationship

Response time matters too. A supplier who takes five days to answer a simple inquiry will likely take five days to answer questions when your order is in production and something goes wrong.

Step 7: Evaluate Their Response to Your First Message (7 minutes)

After completing the above checks, send a simple inquiry. This is the final step of your initial vetting, and it tells you things the profile data cannot.

What to include in your message:

What you are looking for (product, approximate quantity, target price range)
One specific question that requires a real answer, not a copy-paste response
A request for their product specification sheet or catalogue

What to evaluate in their response:

Did they read your message, or send a generic template?
Did they answer your specific question?
Is their English clear enough for reliable communication? (Alibaba)
How long did they take to respond?
Do they ask relevant follow-up questions about your requirements?

Red flags in first responses: Immediate pressure to pay a deposit before answering basic questions • Unwillingness to discuss samples before bulk order • Prices dramatically lower than all comparable suppliers • Insistence that all order confirmation and payment happen off-platform immediately, before any trust is established • Vague or evasive answers to specific technical questions about their own product.

The 30-Minute Checklist Summary

Check	Time	What You’re Looking For
Registration age	3 min	Longer track record; 3+ years preferred
Transaction volume	5 min	Consistent history and recent activity
Reviews	5 min	Specific feedback; reasonable responses to negatives
Factory vs trading company	5 min	Know who you’re dealing with
Certifications	3 min	Relevant, documented, and verifiable
Response rate	2 min	Strong response habits; 90%+ preferred
First message response	7 min	Reads your message; answers specifically
Total	~30 min	Enough to decide whether to continue or walk away

Simple Decision Rule: Green, Yellow, or Red

After the 30-minute check, classify the supplier into one of three groups:

Green — Move to sample order

Good track record, relevant products, clear documentation, responsive communication.

Yellow — Ask follow-up questions first

Some missing information, limited order history, or unclear answers.

Red — Walk away

Recent registration with unusually low prices, poor reviews, no documentation, evasive communication, or payment pressure.

When to Walk Away

Walk away from a supplier if:

They cannot produce documentation for certifications they claim to have
They pressure you to pay before answering basic questions about the product
Multiple reviews mention the same quality or delivery problem
They registered less than one year ago and are offering unusually low prices
They cannot answer a specific technical question about their own product
They insist all payment and order confirmation happen off-platform immediately, with no formal documentation

Walking away from a supplier is free. Walking away from a bad order after payment is expensive.

What Happens After Vetting

A supplier who passes this checklist is not verified — they are qualified to move to the next stage. Vetting reduces risk. It does not eliminate it.

The next stage is a sample order. No amount of profile checking replaces seeing the actual product in your hands, evaluating the packaging, and confirming the specifications match what was agreed.

How to Order Product Samples from China →

If a supplier passes your vetting and your sample check, you have a reasonable basis for placing a small first order. Keep it small. Build trust incrementally. Don’t commit to large volumes until you’ve completed at least one successful transaction end-to-end.

A Note on 1688 Suppliers

Everything in this checklist applies to 1688 suppliers, with two additional points.

First, most profile data will be in Chinese. Google Translate handles this well enough for vetting purposes — you are reading numbers, dates, and ratings, not complex prose.

Second, first-message evaluation is harder because you are communicating through translation. Keep your initial message simple and specific. Avoid idioms. Ask one question at a time. A supplier who handles translated communication clearly and professionally is a positive signal in itself.

Your Next Step

Once you’ve identified a supplier worth pursuing, the next step is understanding your real cost before you negotiate price.

Most new importers negotiate price first and calculate costs later. This is backwards. If you don’t know your landed cost ceiling before you enter a price discussion, you don’t know what number you’re actually negotiating toward.
