TL:DR
To verify a Chinese bedding supplier and separate a real source factory from a trading company, check the business license and unified social-credit code, demand the mill's original specs and a workshop video, and confirm in-house QC. A factory controls production; a trader re-sells without it. Watch for red flags signaling a middleman.

Check the business license and unified social-credit code, demand the mill's original specs and workshop video, and confirm in-house QC. Here's how to tell a real factory from a trader.
Before you wire a deposit, verify who you're really buying from. A source factory controls production; a trading company buys and re-sells without controlling it; a sourcing agent represents you for a fee. To confirm a genuine bedding factory: check the business license and unified social-credit code, request the mill's original specs and workshop video, and confirm in-house QC and a real sampling process. Here's an 8-point check.
Factory vs trading company vs sourcing agent
- Source factory: owns or runs dedicated mill lines — controls weaving, dyeing, QC and loading. Best price and control.
- Trading company: buys from factories and re-sells; adds a markup and a layer between you and production.
- Sourcing agent: works for you (commission) to find and manage suppliers — useful, but not the maker.
An 8-point verification checklist
- 1.Business license: ask for it and confirm the company name, scope (manufacturing vs trading) and registered capital.
- 2.Unified social credit code (18 digits): verify the company is real and in good standing.
- 3.Workshop production video — live, not catalog photos — of the lines making your product type.
- 4.Original mill specs: yarn count, fabric density, GSM and composition, transparent and consistent.
- 5.In-house QC: ask exactly how they control color difference, skipped stitches and defects before bulk.
- 6.Real sampling: they sample at the mill and only run bulk after you sign off a physical sample.
- 7.Export documents: OEKO-TEX compliance, certificate of origin and an inspection report on request.
- 8.References / track record: markets served, repeat clients, and willingness to do a video factory tour.
How to verify a genuine source factory
- 01
Check identity
Request the business license to confirm the company name, scope (manufacturing vs trading) and registered capital, then verify the 18-digit unified social credit code shows a real firm in good standing.
- 02
See the mill
Ask for a live workshop production video of the lines making your product type — not catalog photos — plus the mill's original specs: yarn count, fabric density, GSM and composition.
- 03
Confirm QC & sampling
Pin down exactly how they control color difference, skipped stitches and defects before bulk, and confirm they sample at the mill and only run bulk after you sign off a physical sample.
- 04
Collect proof
Get export documents on request — OEKO-TEX compliance, certificate of origin and an inspection report — plus references and a willingness to do a video factory tour.
Red flags that signal a middleman
- Can't show the workshop, only sends catalog images and prices.
- Vague or shifting fabric specs, or refuses to share original mill data.
- Pushes payment to a personal account or an unrelated company name.
- Prices that undercut everyone — often a sign of substitution in bulk.
Why a Nantong source factory is the safer base
Sourcing from a genuine source-factory chain in the Nantong / Dieshiqiao belt means production, pricing, craft and QC stay in-house — no re-trading markup, no order flipping. If a supplier can show you the workshop, the original specs and a real sampling process, you're talking to the maker, not a layer on top.
Anyone can send a price. A real factory can show you the workshop, the original specs and the sample being made — verify that, and you've removed most of the risk.

Frequently asked questions
- How do I tell a real bedding factory from a trading company?
- A source factory owns or runs dedicated mill lines and controls weaving, dyeing, QC and loading, while a trading company buys from factories and re-sells with a markup. Ask for a live workshop production video, the mill's original specs (yarn count, density, GSM, composition) and proof of in-house QC — a maker can show all three.
- What documents should I request to verify a Chinese supplier?
- Ask for the business license to confirm the company name, scope (manufacturing vs trading) and registered capital, plus the 18-digit unified social credit code to verify the firm is real and in good standing. On request a genuine factory can also provide OEKO-TEX compliance, a certificate of origin and an inspection report.
- What are the red flags that signal a middleman, not a factory?
- Watch for a supplier who can't show the workshop and only sends catalog images, gives vague or shifting fabric specs, pushes payment to a personal account or unrelated company, or quotes prices that undercut everyone — often a sign of substitution in bulk.
- What's the difference between a source factory, a trading company and a sourcing agent?
- A source factory makes the goods and offers the best price and control; a trading company buys and re-sells, adding a markup and a layer between you and production; a sourcing agent works for you on commission to find and manage suppliers but isn't the maker. Buying from a Nantong source factory keeps production, pricing, craft and QC in-house.
