How to Verify a Chinese Supplier: The Complete Due Diligence Checklist (2026)

The most expensive sourcing mistake isn't paying 10% too much per unit. It's sending a $15,000 deposit to a company that can't deliver — or delivers garbage. According to import dispute data, roughly 20-30% of first-time importers from China experience a significant problem with their first order: wrong specifications, quality issues, or outright non-delivery.

Most of these problems trace back to inadequate supplier verification. The importer found a supplier on a B2B platform, was impressed by product photos and a polished company profile, negotiated a good price, wired a deposit — and only then discovered that the "manufacturer" was actually a trading company, or that the factory had 8 employees instead of the claimed 200.

If you haven't yet identified potential suppliers, start with our guide on how to find Chinese manufacturers. Proper verification takes 1-2 hours per supplier using the methods in this guide. For a shortlist of 5 suppliers, that's half a day of work that can save you thousands of dollars and months of delays. Here's exactly how to do it.

This is the foundation of all verification — and the step most importers skip. Every Chinese company has an official Chinese legal name (公司全称) registered with the government. This is different from their English brand name, Alibaba store name, or what their salesperson calls the company.

How to find it:

Ask the supplier directly: "What is your registered Chinese company name (公司全称)?" A legitimate company will provide this immediately. If they hesitate or provide only an English name, that's your first red flag.

On Alibaba: Go to the supplier's profile page → "Company Overview" → look for "Business Type" and "Company Name." The Chinese name is sometimes listed alongside the English name.

On 1688.com: The Chinese company name is displayed prominently on every store page.

On ExpoAlive: Every company profile shows the registered Chinese name alongside the English name, sourced directly from government databases.

Why this matters: Without the legal Chinese name, you cannot look up the company in any government database. Everything else — employee count, business type, registration status — depends on having the correct legal name.

Once you have the Chinese company name, look it up on the National Enterprise Credit Information Publicity System (国家企业信用信息公示系统, gsxt.gov.cn) or commercial platforms like Tianyancha (天眼查) or Qichacha (企查查).

What to check:

Registration Status (登记状态): Must show 存续 (active/existing) or 在营 (in operation). If it shows 注销 (cancelled), 吊销 (revoked), or 迁出 (relocated), stop immediately. A cancelled or revoked company cannot legally operate.

Date of Establishment (成立日期): Older companies are generally more reliable. A manufacturer established in 2005 has survived 20+ years of competition — that's meaningful. A company established 6 months ago claiming to be an "experienced manufacturer" should be questioned thoroughly. Be cautious with companies less than 2 years old, especially for orders over $5,000.

Registered Capital (注册资本): This is the capital the founders committed to invest. For manufacturing companies, look for at least ¥1 million (roughly $140,000) in registered capital. Very low registered capital (under ¥500,000) combined with manufacturing claims is suspicious. Note: since China reformed its capital registration system, registered capital is pledged, not necessarily fully paid. Check the "paid-in capital" (实缴资本) if available.

Business Scope (经营范围): This lists what the company is legally permitted to do. A genuine manufacturer will include terms like 制造 (manufacturing), 生产 (production), 加工 (processing). A trading company's scope will emphasize 贸易 (trade), 进出口 (import/export), 销售 (sales). Some companies are legitimately both — they manufacture some products and trade others. But if the scope is purely trading with no manufacturing terms, the company is definitively not a factory.

This is the single most powerful verification data point — and the one that trading companies cannot fake.

In China, every employer is legally required to pay social insurance (社会保险) for every employee. The social insurance count (参保人数 or 社保人数) is reported to the government and reflects actual headcount based on mandatory insurance payments.

How to interpret the number:

A real manufacturer of physical products needs workers: machine operators, quality inspectors, assembly line workers, warehouse staff, and administrative personnel. For a small factory: expect 20-50 insured employees. For a medium factory: 50-300. For a large factory: 300+.

If a company claims to be a manufacturer with "200 workers" but the social insurance count shows 8 people — it's almost certainly a trading company with an office and a sales team. They buy from factories and resell to you with a 15-30% markup. (Learn more about this distinction in our manufacturer vs trading company guide.)

Important nuances:

Some factories in China hire temporary or seasonal workers who aren't covered by social insurance. This means the social insurance count might understate the true headcount by 20-40%. A factory showing 30 insured employees might actually have 40-50 total workers including temps. This is normal.

What's NOT normal: a company showing 5 insured employees claiming to have 200 workers. The social insurance count will never be off by 40x.

On ExpoAlive, we display the social insurance employee count directly on every company profile, sourced from government records. This is not the number the company tells us — it's the number the government records show.

Government data tells you whether a company is legitimate. But it doesn't tell you whether their production line can actually make your product at the quality and volume you need. For that, you need to see the factory — either in person or via video.

In-person factory visit: The gold standard. Walk the production floor, count machines, observe workers, inspect raw materials, and review their quality control process. Pay attention to: How organized is the factory floor? Are machines running or idle? Do workers seem experienced? Is there a dedicated QC area with testing equipment? Are raw materials stored properly?

Live video call: The next best thing. Ask for a live (not pre-recorded) video tour of the factory during working hours. Request that they show: the main production area with machines running, the raw material warehouse, finished goods storage, the QC inspection area, and the company's business license displayed on the wall. Watch for suspicious signs: filming only a small area (might be a rented corner of someone else's factory), no workers visible, or the tour guide seeming unfamiliar with the equipment.

Pre-recorded factory videos: Better than nothing, but can be misleading. Some trading companies film at their supplier's factory and present it as their own. If a supplier only provides a pre-recorded video and won't do a live call during Chinese business hours (9am-5pm Beijing time), be cautious.

ExpoAlive's Factory Visit program sends our team to physically visit and film factories. Companies with the FACTORY_VISITED (gold badge) status have been verified through an in-person visit with video documentation.

Depending on your product and target market, you may need specific certifications. The critical thing: verify that the certificates are real, current, and belong to the company you're evaluating — not a parent company, subsidiary, or unrelated entity.

Common certifications to check:

ISO 9001 (Quality Management): The baseline standard. Most established Chinese factories have this. Verify by checking the certificate number with the issuing body or on CNCA's certification inquiry system (cx.cnca.cn). Beware: some companies purchase ISO certificates from corrupt certification bodies. Check the issuing body's accreditation.

Product-specific certifications: CE (European market), UL (US electrical safety), FDA registration (US food/medical), REACH/RoHS (EU chemicals/electronics), BSCI or SEDEX (social compliance). Each has a verification database — ask the supplier which body issued the certificate, then verify directly.

Red flags with certifications:

Expired certificates presented as current. Certificates belonging to a different company name. Certificates issued by unknown or unaccredited bodies. Refusal to provide certificate copies ("we can show you during the factory visit"). A legitimate factory will email you clear copies of all relevant certificates within 24 hours of request.

Even after thorough verification, never commit to a large first order. Start with samples or a small trial order to verify product quality firsthand.

Sample evaluation process:

1. Order samples from your top 3-5 verified suppliers. Pay for samples — free samples often receive less attention. Typical sample costs: $50-$500 depending on product complexity, plus shipping ($30-$80 via express courier).

2. Provide identical specifications to each supplier so you can make a fair comparison. Include: material requirements, dimensions with tolerances, color/finish specifications, performance criteria, and packaging requirements.

3. When samples arrive, test them against your specifications. For consumer products: test durability, functionality, and appearance. For industrial products: test to specification with measuring equipment. Document everything with photos.

4. Ask each supplier to explain their quality control process: What do they inspect at incoming material stage? What do they check during production? What's their final inspection process? How do they handle defective items?

Trial order considerations:

If samples pass, place a trial order at the supplier's minimum MOQ rather than your target volume. This validates the factory's ability to maintain quality at production scale — not just for a hand-picked sample. Arrange pre-shipment inspection (PSI) by a third-party inspection company (SGS, Bureau Veritas, Intertek, or local agencies at $200-$400 per inspection) before the order ships.

After verifying hundreds of Chinese suppliers, these are the warning signs that most reliably predict problems:

They won't provide their Chinese company name. Every legitimate Chinese business has a registered Chinese name. If a supplier provides only an English name and deflects requests for the Chinese registration name, they're likely hiding something — possibly that they're an unregistered entity or that their registration type is "trading company."

Social insurance count doesn't match their claims. The supplier says they have 300 employees, but government data shows 12 insured workers. This is the most reliable indicator of a trading company masquerading as a manufacturer.

They're reluctant to do a live video call. Any factory that's actually producing your product should be willing to show you the production floor via a live video call during Chinese business hours. Reluctance suggests they either don't have a factory or are using someone else's.

Prices are significantly lower than competitors. If a supplier's price is 30%+ below other verified manufacturers, be skeptical. Common explanations: they're quoting a lower-quality material than specified, they plan to substitute cheaper materials during production, or they're buying from you as a loss leader to lock in the relationship and raise prices later.

They push you to pay via personal bank account or Western Union. Business payments should go to a company bank account matching the registered business name. Personal accounts and Western Union transfers have essentially zero buyer protection. PayPal or T/T to a company account are standard.

The registered address is a residential building or virtual office. Look up the company's registered address on a map. If it's an apartment building, a shared office space, or a clearly residential address — it's a trading company operating from an office, not a factory with production equipment.
