The real risk of picking the wrong supplier
China has more than 400,000 registered exporters. Most of them are serious and want to build long-term relationships with Brazilian buyers. But a small minority, very active on platforms such as Alibaba, Made-in-China and DHgate, exists precisely to take advantage of importers who do not know how to check who they are dealing with.
The most common losses do not come from outright scams. They come from apparently normal situations: the supplier delivers the product, but the quality is far below the sample. Or delivers on time, but with the wrong specifications. Or disappears after payment and leaves you with no product and no legal recourse.
The good news: checking a Chinese supplier is not difficult. It takes method, some patience and knowing what to look for. The 5 methods below run from the basic check anyone can do for free to the deeper validations that protect higher-value orders.
Method 1: Read the Alibaba profile properly
Alibaba is the largest B2B platform in the world and has verification systems of its own. But many importers look at the badges without understanding what they mean, or ignore them altogether.
What the Gold Supplier badge actually tells you
Gold Supplier is a paid badge: any company can buy it. On its own, therefore, it guarantees nothing. What matters is how many years the supplier has held it. A Gold Supplier of 1 year could be anything. Five years or more, with transaction volume, is a far more solid sign of an established company.
Always look at:
- Years as Gold Supplier: the longer, the better
- Trade Assurance: payment protection through Alibaba; serious suppliers switch it on
- Overall rating: above 4.5 stars is reasonable; read the negative ones
- Number of verified transactions: high volume indicates a real track record
- Response time: serious suppliers reply in under 24 hours
Practical tip: In the negative reviews, pay attention to patterns. If several buyers complain about the same problem, quality different from the sample, delays in communication, missing parts, that is a consistent signal, not an isolated case.
Check the company outside Alibaba
Copy the exact company name (in English and, if possible, in Mandarin) and search on Google. Add "scam", "fraud" or "review" to the search. Importer forums such as Importers.io, Made-in-China and Reddit groups often carry reports on problem suppliers.
Also confirm that the company address shows up on Google Maps as a real commercial or industrial site, not a residential flat or a generic virtual office address.
There is a filter that comes before all of these, and it is geographical: a supplier of the right product in the wrong city is almost never a factory. The map of China’s industrial clusters says where each thing is made, and it is the first question to ask before checking anything else.
Method 2: Order samples before any production run
The sample is the only concrete reality check you have before committing capital to a large order. No photo, no video and no Alibaba description replaces holding the physical product in your hands and testing it.
| What to assess in the sample | Why it matters |
|---|---|
| Finish and materials | Many suppliers send samples from the premium line; the production run comes in lower quality |
| Dimensions and specifications | Variations of a few millimetres can break the fit with other components or with the packaging |
| Individual packaging | Product that arrives damaged because of weak packaging drives a high return rate |
| Documentation included | Manual in Portuguese? Certifications required in Brazil? |
| Sample delivery time | How the supplier handles small deadlines tells you how they will handle large orders |
Typical sample costs run between US$ 30 and US$ 200 plus express shipping (DHL, FedEx, UPS), usually US$ 40 to US$ 80. It is a trivial investment next to the risk of receiving a whole container of substandard goods.
Practical tip: Order samples from at least 3 different suppliers before deciding who to work with. The side-by-side comparison reveals quality differences that would be invisible if you assessed a single supplier.
Document the approved sample
When you approve the sample, photograph it in detail, record the exact specifications in a written document and include a clause in the purchase contract tying the quality of the order to the approved sample. That creates a legal basis if the delivered product turns out to be different.
Method 3: Audit the factory, in person or through an inspector
For orders above US$ 5,000, or whenever the product requires mandatory certification in Brazil, a factory audit stops being optional and becomes necessary. The audit confirms that the factory exists, that it has real production capacity and that it operates within the agreed standards.
In-person visit
If you are travelling to China, whether for the Canton Fair or for a sourcing trip, set aside time to visit the factory yourself. A half-day visit is enough to check the premises, meet the production team and gauge the real scale of the operation.
What to observe during the visit:
- Real size of the premises versus what the profile claims
- Production equipment actually running (not merely on display)
- Raw material stock consistent with the declared capacity
- ISO, CE or other certificates on the wall (they can be verified)
- Quality control line: does it exist or is it improvised?
- Product being made at that moment: does it match what the supplier sells?
Third-party inspector
If you are not in China, you can hire an independent inspection company to run the audit for you. Firms such as SGS, Bureau Veritas, Intertek and QIMA have offices across China and provide detailed reports with photos, measurements and a compliance assessment.
Typical factory inspection costs: US$ 200 to US$ 400 per inspector per day, depending on the region and the firm. For orders worth several thousand dollars, that cost pays for itself many times over by avoiding a problem shipment.
Practical tip: The pre-shipment inspection, carried out when 80% of production is complete, is even more valuable than the initial audit. It catches quality problems before the product leaves China, while there is still time to correct or renegotiate.
Method 4: Check certifications and export history
A serious Chinese supplier that has been exporting for years has traceable documentation. Asking for and verifying those documents is one of the fastest filters for separating established companies from improvised operations.
Business License: the base document
Ask the supplier for the business registration number (Business License). With it, you can check the company in China's national company registry (gsxt.gov.cn) and confirm:
- Registered company name
- Official address
- Active or inactive status
- Declared share capital
- Registered line of business
If the supplier refuses to give you the registration number or comes up with excuses for not sharing this basic document, treat it as a serious warning sign.
Certifications that matter for Brazil
| Product | Certification in China | Requirement in Brazil |
|---|---|---|
| Electronics, home appliances | CE, RoHS, FCC | INMETRO mandatory |
| Toys | EN 71, ASTM F963 | INMETRO mandatory |
| Food, supplements | HACCP, ISO 22000 | MAPA / ANVISA |
| Industrial equipment | ISO 9001, CE | Sector-specific NR |
| Cosmetics, personal care | ISO 22716 | ANVISA mandatory |
Ask for the certificates, check their validity and confirm that the certification number is traceable with the issuing body. Forged certificates do exist: validating with the issuing body is the only way to be sure.
Export history to Brazil
Suppliers with experience exporting to Brazil understand Brazilian customs paperwork, know the INMETRO and ANVISA requirements and have partner freight forwarders on that route. Ask directly: "Have you exported to Brazil before? Do you have references from Brazilian buyers?" A serious supplier answers without hesitating.
Method 5: Work with a specialist intermediary
The four previous methods take time, knowledge and, in some cases, a physical presence in China. For importers without that structure, especially those starting out or expanding into new products, a specialist intermediary closes all of those gaps at once.
A reliable intermediary with a presence in China and knowledge of the Brazilian market does the following for you:
- Supplier qualification: checking documentation, track record and premises before any commercial contact
- Negotiation in Mandarin: real terms that a foreign buyer cannot reach without command of the language and the culture
- On-site quality inspection: at the factory and before shipment
- Contract management: clauses that protect the Brazilian buyer under the applicable law
- Logistics and customs paperwork: coordinating transport and the documents needed for clearance in Brazil
Note: There is an important difference between a Brazilian intermediary operating in China and a local Chinese agent hired directly. The Chinese agent may have a financial incentive to steer you towards suppliers who pay them a commission, not necessarily the best ones for you. A Brazilian intermediary has the right alignment of interests: the client's operation succeeding.
Warning signs: when to be suspicious straight away
Beyond the 5 verification methods, some behaviours should raise an immediate flag, whatever the rest of your analysis says:
Price far below the market
If the price offered is 30% or more below every competitor with no clear technical justification (very large scale, alternative raw material), something is almost certainly wrong: either lower quality or a counterfeit product.
Demanding 100% up front by bank transfer
Serious suppliers accept terms such as 30% up front plus 70% before shipment, or Trade Assurance through Alibaba. Demanding the full transfer in advance, especially on a first order, is a warning sign.
Refusing to provide basic documentation
Business License, verifiable address, references from other buyers: any refusal to share basic documentation should end the negotiation.
Evasive communication about specifications
If the supplier dodges specific technical questions ("can you confirm the material thickness?", "what is the operating voltage?"), they probably do not know or do not want to commit to what they are selling.
Last-minute change of bank account
One of the most common frauds: the supplier asks to change the payment account at the last moment before the transfer. Always confirm bank details through a channel other than email (video call, phone) before making any payment.
Frequently asked questions about checking suppliers
How do I know whether a supplier on Alibaba is reliable?
Check whether the supplier has held the Gold Supplier badge for at least 3 years, has Trade Assurance active, a rating above 4.5 stars and a meaningful volume of verified transactions. Read the negative reviews to understand the weak points and confirm that the company address shows up on Google Maps as a real factory, not a residential flat.
Is it worth ordering a sample before placing a large order?
Yes, always. The sample is the only way to confirm real quality before committing capital to a large order. The cost of a sample, usually US$ 30 to US$ 200 plus express shipping, is trivial next to the risk of receiving a whole container of substandard product. On top of that, the way the supplier handles the sample request already says a great deal about how serious they are.
What is a factory audit and when is it necessary?
A factory audit is a visit, either in person or through a third-party inspector, to verify that the factory exists, that it has real production capacity and that it operates within the agreed standards. It is necessary for orders above US$ 5,000, for products that require mandatory certification in Brazil (INMETRO, ANVISA, MAPA) and for suppliers with whom you intend to build a long-term relationship.
How can I check whether a Chinese company really exists?
Ask for the business registration number (Business License) and check it in China's national company registry, available at gsxt.gov.cn. Confirm the address, the registered name and the active status. Another method is to search the company name on Google together with 'scam' or 'fraud' and see whether it appears in importer forums. Specialist intermediaries such as BCVN carry out this check as part of the supplier qualification process.
What are the main warning signs of a dishonest supplier?
The main signs are: refusing to provide the business registration number or a verifiable address; a price far below the market with no justification; demanding 100% payment up front by bank transfer; confused or evasive communication about product specifications; frequent changes of bank account or of the company receiving the payment; and excellent quality samples followed by very different products in the production run.
Why use a Brazilian intermediary to check suppliers in China?
An intermediary with a presence in China and knowledge of the Brazilian market covers every gap the importer cannot close from a distance: an in-person factory visit, negotiation in Mandarin, real-time document checks, quality inspection before shipment and proper contractual protection. A reliable intermediary also takes responsibility for the outcome, unlike a local Chinese agent whose interests may be aligned with the supplier rather than with you.
