Supplier Verification Checklist

Before you wire money to a China wholesale supplier, run through this checklist. Written for Southeast Asia resellers and dropshippers — no Chinese, no sourcing agent required.

In this checklist:

Why verification matters (what actually goes wrong)
Factory, wholesaler or reseller — how to tell
8 supplier signals you can check in 10 minutes
The sample test — your cheapest insurance
Common sourcing scams and how they work
Hard red flags: walk away immediately

1. Why verification matters

Most sour sourcing stories from new cross-border sellers are not dramatic frauds. They are boring, avoidable mistakes: a "factory" that was actually a reseller two markups away from the source, a batch that didn't match the sample photo, a supplier who quietly substituted cheaper fabric when you re-ordered. Verification is less about catching criminals and more about making sure your margin assumptions survive contact with reality.

The good news: on platforms like 1688, most of the evidence you need is already on the listing page. You just need to know what to look at — and how to compare several suppliers for the same item instead of trusting the first result.

2. Factory, wholesaler or reseller — how to tell

Source factory (源头工厂) — makes the product or holds the brand's stock. Best prices, but may have higher MOQs and slower replies. Usually shows a factory-type business badge.
Wholesaler / distributor (档口) — buys from factories and sells in smaller mixed batches. Faster, more flexible, one or two markups up.
Reseller listing — copies a popular listing and marks it up. Often nearly identical photos at a higher price. This is who you overpay when you don't compare.

None of these are "bad" — a wholesaler can be the right choice for small mixed orders. The point is to know which one you're talking to and whether the price matches the role. Comparing 3–5 listings of the same style is the fastest reality check: a spread wider than ~15% usually means someone in the list is marking up.

3. Eight supplier signals you can check in 10 minutes

Business type badge — factory vs trader badge on the supplier profile.
Years in operation — suppliers running 3+ years with sustained sales are much lower risk than brand-new storefronts.
Repeat-purchase rate — a meaningful share of buyers coming back is the strongest single trust signal on 1688.
Review photos from real buyers — skip the star rating; open the photo reviews and look at what people actually received.
Stock and variant depth — real inventory holders show granular color/size stock; thin or fake-looking variant data suggests a middleman syncing someone else's catalog.
Consistency of tiered prices — factory pricing usually has sensible quantity tiers. A single too-good-to-be-true price is a hook, not a deal.
Response behavior — ask one specific question ("exact fabric weight of SKU B?"). Vague, copy-paste answers are a preview of your after-sales experience.
Same-style price comparison — search the same style (keyword or photo) across suppliers and see where your candidate sits in the spread.

Steps 1–7 need you to read the Chinese listing page. That's exactly what Sourmo does for you: it translates and structures 1688 listings into English (and other SEA languages), so you can run this checklist without reading a character of Chinese.

4. The sample test — your cheapest insurance

For any product you plan to resell in volume, order one sample first, and treat it as a specification, not a gift:

Photograph the sample on arrival — fabric, stitching, labels, packaging.
Record the agreed spec (material, weight, size chart) in writing with the supplier.
When the bulk batch arrives, spot-check against the sample photos. Any substitution is grounds for a discount or return — and evidence if a dispute opens.

A sample costs you a few dollars and one week. A bad bulk order costs you a season and your shop's ratings.

5. Common sourcing scams and how they work

The bait photo

Beautiful studio photos, shipped product is a lower-grade version. Defense: photo reviews from other buyers + your own sample test.

The "too cheap" listing

Price far below the same-style spread. Either the quality is different, the quantity tier is unrealistic, or stock doesn't exist. Defense: always compare the same style across suppliers before believing any price.

The off-platform payment request

Someone asks you to pay by personal transfer "for a discount" — no platform order, no buyer protection, no recourse. Defense: never. Keep every order on-platform.

The silent substitution on reorder

First order perfect, reorder quietly downgraded. Defense: written spec + arrival photos for every batch, not just the first.

6. Hard red flags — walk away immediately

Pressure to pay outside the platform, for any reason.
Refuses to name the exact material / spec in writing.
Reviews full of "not as described" with photo evidence.
Price more than ~20% below the same-style spread with no explanation.
Brand-new storefront with a "hot" product and heavy discount marketing.

If a supplier trips even one of these, move on. On a wholesale marketplace with thousands of listings of the same style, you never need to gamble on a specific seller.

Run this checklist in minutes, not hours

Sourmo translates and structures 1688 wholesale listings into your language, lets you search by keyword or photo, and puts comparable suppliers for the same style side by side — so steps 4, 6 and 8 of the checklist take seconds.

Compare suppliers before you pay

Keyword or image search, structured listings, side-by-side supplier comparison — no Chinese needed.
