Most supplier vetting happens at a distance. You read a company profile, look at product photos, exchange emails, maybe run a company name through a database. All of it can be true and still leave you with no idea who you are actually dealing with.
A trade show narrows that gap for a few days a year. An exhibitor has committed resources to attending, brought staff and samples, and may be able to show company and product documentation on the spot. That gives you more to examine than a directory listing does, and someone standing there to answer for it. None of it removes the need for independent verification.
One thing to hold onto throughout. What follows divides into two kinds of evidence, and they are not equal. Documents and registry records can be checked against an independent source. Everything else on this page is a soft signal, useful for deciding who to spend more time on and worthless as proof. Soft signals are flagged as such below. Acting on one without documentary or third-party confirmation is how buyers talk themselves into suppliers.
Ask to see the business licence
The most useful document on a Chinese supplier’s booth is one that is easy to overlook. Every registered company has a business licence, the 营业执照. Many exhibitors will show it readily, though a salesperson may only have an electronic copy, may need to ask someone, or may not have authority to hand it over on the spot. Reluctance is not proof of anything by itself. What matters is whether you get it before you commit to anything.
Four things on it are worth your time, plus a fifth that needs more care than the rest:
The Unified Social Credit Code is 18 characters and unique to the company. Photograph it. You can check it against the National Enterprise Credit Information Publicity System, which is the official government registry and free. Be warned that it is Chinese-language only and uses a drag-to-verify captcha that tends to defeat foreign visitors on a phone. Treat it as an evening task at the hotel, and bring someone who reads Chinese if you can.
The registered company name in Chinese is the one that matters, and it will often differ from the booth signage, because signage usually carries a brand. The question to settle is how the registered entity connects to the exhibitor, to whoever will issue your invoice, and to the party you would actually be contracting with. Groups routinely separate the manufacturing entity from the export entity. Ask on the spot rather than discovering it three months later on a proforma.
The business scope, 经营范围, tells you what the company has registered to do. Look for 生产 or 制造, meaning production or manufacture, alongside 贸易 or 销售, meaning trade or sales. Treat this as a screening signal rather than proof. Scope is self-declared at registration, and plenty of trading companies include production wording to keep their options open. A scope with no production terms at all is meaningful. A scope that includes them is a reason to keep asking, not an answer.
The establishment date is the incorporation date of that legal entity. It is not the same as how long the factory has run, how old the brand is, how experienced the owners are, or whether an older business was reorganised under a new company. A recent date next to “20 years of experience” on the brochure is a question to ask, not a contradiction to catch.
Registered capital needs care, because the rules changed recently and older guidance is now misleading. Before the 2024 reform, there was no general statutory limit on how long shareholders could take to pay in what they had subscribed, though a schedule was still set in the company’s own articles, sometimes decades out. Under the revised Company Law in force from 1 July 2024, shareholders of a limited liability company must pay their subscribed capital in full within five years of establishment. Companies registered before 30 June 2024 fall under transitional rules rather than the same requirement: broadly, where a remaining contribution period would run more than five years beyond 1 July 2027, it has to be shortened.
The practical point for a buyer is that registered capital is a commitment, not cash held. Paid-in figures may appear in enterprise disclosures and annual reports on the registry, but that information is company-reported and may not have been independently verified before publication. Treat a large registered capital as context, never as evidence of financial standing.
Work out whether you are talking to the factory
Trading companies are not a problem in themselves. Many are genuinely useful, especially for small orders, mixed containers or buyers who do not want to manage a factory relationship directly. The problem is not knowing which one you have.
Start with the addresses. Ask where the factory is, then compare that with the registered address on the business licence. They will not always match, since head offices and plants are often in different places, but the supplier should be able to explain the relationship without difficulty.
Do not use speed of answer as your test. Sales staff at a real factory frequently do not carry line counts or per-shift capacity in their heads, because that sits with the production department. How someone answers is a soft signal at best. A person close to the plant will often say they need to check with production and come back with a figure, while someone at arm’s length tends to stay general. Plenty of counterexamples exist in both directions, so use this to decide who to keep talking to and nothing more.
Ask instead about things a person who works there absorbs by proximity. Which process steps happen in house and which are outsourced. Where the material comes in from. What the plant does during the slow season. How long the walk is from the office to the line.
Then ask to see photographs of the production floor on their phone rather than in the catalogue. Catalogue photos are frequently stock images or a client’s factory. Phone photos are a slightly better soft signal, since someone who visits the plant tends to have incidental shots of it, but images are trivially copied and prove nothing on their own.
Work out how far each certificate can be traced
A printed certificate is worth exactly as much as whatever stands behind it, and how much you can check varies enormously between schemes. A wall of logos on a booth panel tells you nothing until you know which of them can be traced to a source.
Photograph the certificate itself, and record the certificate number, the issuing body and the expiry date. Then sort what you have into three groups. FDA claims and CE marking sit outside these groups and are handled separately below, because neither fits a single tier.
Verifiable on the spot. UL certifications can be looked up in UL Product iQ, which is free but requires you to register an account, so set that up before you travel.
Verifiable, but not always. ISO 9001 and similar management system certificates can often be checked through IAF CertSearch or the certification body’s own directory, though coverage depends on whether the accreditation body participates. Note who issued it. An unfamiliar certification body with no accreditation behind it is the thing worth catching.
Not publicly verifiable at all. Note first that amfori BSCI is an audit and monitoring system rather than a certification. It records conditions and findings at a particular site at the time of the assessment; it does not certify complete or continuing compliance with the code of conduct. Both amfori BSCI and Sedex SMETA reports live on closed platforms and are visible only to the audited company and the business partners it grants access to. There is no public lookup, so a printed summary at a booth cannot be checked against anything. If these matter to you, the only real route is to ask the supplier to share the report with you through the platform itself once you are in a business relationship.
FDA claims
FDA is a mixed picture, and worth unpicking, because “FDA registered” appears on a great many booth panels and means less than most buyers assume.
Medical device establishment registrations and device listings are searchable in the FDA’s Establishment Registration and Device Listing database. Drug establishment registrations are published separately, through the FDA’s Drug Establishments Current Registration Site. They are two different systems, so search the right one for the product in front of you.
Food is different again. The FDA does not publish a searchable list of registered food facilities, so an ordinary buyer cannot confirm a food facility registration number through a public FDA database. The supplier may disclose its own registration details to you, which is worth asking for, but that is disclosure by the party you are checking rather than independent public verification.
Registration is not approval, and this is the single most common misunderstanding on a booth panel. The FDA states plainly that when a facility registers its establishment and lists its devices, the resulting database entry does not denote approval, clearance or authorisation of that facility or its products. The FDA also does not issue registration certificates to medical device facilities, and does not certify the registration information of firms that have registered. A framed “FDA Registration Certificate” bearing an FDA logo is not an FDA document. Confirming a supplier appears in the database tells you the establishment registered and what activity it declared. Whether a specific product has been cleared or approved is a separate question with a separate pathway.
Food-contact packaging is where this most often goes wrong. Facilities dealing only in food-contact substances, packaging and closures among them, are generally not required to register as food facilities at all. That does not make a registration number on a booth panel false. The company may carry out other activities that do require registration, or the number may belong to a different FDA programme entirely. What it does mean is that a food-facility registration number establishes nothing by itself about whether the packaging is compliant or FDA approved. Ask which FDA programme the number relates to and why it is relevant to the product in front of you.
One useful public resource for packaging is the FDA’s Inventory of Effective Food Contact Substance Notifications, which lists the substance, the notifying manufacturer or supplier, the intended use and any limits on conditions of use. Be careful how much weight you put on a material’s absence from it. An FCN is only one of several routes to compliance, and depending on the substance and its use, the basis may instead be an applicable food additive regulation in 21 CFR, GRAS status, a prior sanction, or a Threshold of Regulation exemption. Where an FCN is the basis, one detail matters at a booth: it is effective only for the manufacturer or supplier named in it. Customers buying from that named supplier can rely on it, while a different factory producing the same material cannot. Check whose name is on the notification and how the company you are talking to relates to it.
CE marking
For many product categories CE is a self-declaration by the manufacturer, and no central public database of CE certificates exists. Where the applicable legislation requires a notified body to be involved in the relevant conformity assessment, that body’s four-digit identification number appears alongside the CE marking. You can then look the number up in the EU’s NANDO database, now hosted in the European Commission’s Single Market Compliance Space, and confirm that the body is genuinely designated and notified for the legislation, the product and the conformity assessment procedure in question. Notified bodies are designated and notified rather than accredited for a directive, and the distinction matters when you read what the database actually says. A CE mark on its own is not third-party verification.
Two more practical points.
Certification scope varies by scheme, so read the scope statement rather than the logo. Product certifications such as UL cover particular models, components or product families. CE documentation concerns specific products and the legislation that applies to them. An ISO 9001 certificate covers defined organisational activities at named sites. BSCI and SMETA are site-level social audits of a particular facility, not product certificates at all. Check the site name and the product detail on the document in front of you, not just the certificate number.
Plan for connectivity as well, because some international verification services are unreliable or unreachable on mainland Chinese networks. Do the essential checks before you travel and save the records securely so you have them offline in the hall. If you are considering a VPN or a corporate remote-access service, check current Chinese rules and your own organisation’s security policy first. VPN services are regulated in China and require government licensing, and UK travel advice warns that most VPN use may be unlawful.
Handle the samples, and compare across booths
Photographs hide weight, smell, rigidity, finish quality, weld lines and visible inconsistency between units. Measurement is a separate exercise, but fit and obvious variation show up in the hand. Handling a sample tells you things no specification sheet will.
The bigger opportunity is comparison. In a single hall you can pick up the same category of product from six or eight suppliers within an hour. That is the fastest way to calibrate what normal looks like at a given price point, and it makes an outlier obvious. A quote far below everything else in the hall is information rather than a bargain, and worth asking about directly.
Ask whether the sample is from production or made for the show. Show samples are often hand-finished and are not representative. A supplier who volunteers that distinction before you ask is a mild soft signal in their favour, though a well-drilled salesperson knows to say it too.
The person standing at the booth
Look at the email address on the business card. A company domain is a weak signal of some infrastructure behind the person, and a free address at 163.com or qq.com is common in smaller operations and is not disqualifying. Domains cost almost nothing, so this proves very little either way. Note it and move on.
Watch who defers to whom. This is a soft signal, but a useful one. If the person you have been emailing for six months turns out to be a hired interpreter who has never seen the factory, that changes what your emails have actually been worth. Interpreters and agency staff are common at large fairs and their presence is not itself a problem, so long as you know who you are dealing with.
Ask about something that went wrong. A supplier who can describe a shipment that was late, a batch that failed inspection and what they changed afterwards has usually been running long enough to have had problems. Treat the answer as a soft signal. Some suppliers will not discuss a customer’s order in front of a stranger, which is a defensible reason to say little, so read the manner of the refusal rather than the refusal itself.
Booth size and hall position
Floor space at major Chinese fairs is expensive, so a large stand in a main hall suggests the company has committed real money. Treat that as a soft signal only. Booth costs may be shared between related companies, subsidised by a local government or trade bureau, or carried by a group parent, so the stand does not reliably tell you about the entity you would be contracting with. It says nothing at all about quality, about suitability for your order size, or about willingness to work with a buyer your size.
The reverse is worth remembering. A small booth in a satellite hall can be a specialist manufacturer that does one thing very well and has no marketing budget. Position tells you about spend and about which delegation or category allocated the space, not about capability.
Screening standards vary significantly between fairs, and it is worth asking any organiser what company, product and intellectual property checks they perform before admitting exhibitors. The Canton Fair sits at the more structured end. Applicants must meet published qualification standards and submit supporting information, and submitting an application does not itself guarantee admission or a booth allocation. Exhibitors are also required to avoid infringement and may be called on to produce ownership or authorisation evidence where a right is asserted against them. That is not the same as every product on display being patented or trademarked, and most ordinary goods are neither.
Screening at the door does not clear the hall, though, and historical figures reported from the fair’s complaint process illustrate it. The Canton Fair began formally addressing intellectual property complaints in 1992 and set up a dedicated Special IP Group in 1997; its later rules provide for an on-site Complaint Station handling intellectual property and trade disputes.
If you are a rights holder rather than a buyer, prepare ownership, registration and authorisation documents before the fair, and note that representatives acting on a rights holder’s behalf may need to complete the fair’s advance authorisation or intermediary registration process. Once a complaint is accepted, officials inspect the booth and require the exhibitor to produce proof of ownership or authorisation, and items that cannot be defended are sealed over or taken off display. Practitioner guidance puts coordination of an accepted complaint and the booth inspection at roughly four to six hours, though timing depends on the case and the workload at the time. At the 118th Canton Fair in autumn 2015, the station handled 603 cases involving allegations against 860 companies, and 368 companies were determined through the fair’s own process to constitute alleged infringement. These were preliminary determinations made through the fair’s complaint process, not court judgments or final findings of legal liability. A separate figure reported in 2019 put the complaint station’s caseload at 382 for the edition current at that time, at a fair with more than 25,000 exhibiting companies.
Both figures are years old and neither describes the current position, so treat them as illustrative rather than current. Read them both ways in any case. A fair that runs a complaint station and publishes caseloads is policing its floor, which is worth something. It is also a fair where hundreds of exhibitors a session attract complaints that the fair’s process preliminarily upholds. Pre-screening removes a layer of applicants before you arrive. It does not remove the need to check the company standing in front of you.
What a booth still cannot tell you
A booth tells you nothing about financial health, whether the company will still exist in eighteen months, or whether it is carrying debt. It tells you nothing about whether your order will be subcontracted to a workshop you have never seen, which happens, is not always a problem, and is something you should know about rather than discover. It does not tell you how they behave when a shipment is late and your money is already committed.
For those, you need a factory audit, a credit report, or a third-party inspection at production. A trade show is the place to shortlist and to eliminate. It is not a substitute for verification at the point of production.
Use the trip for a factory visit
The strongest reason to treat a show as a verification exercise is that you are already in the country.
Most major Chinese fairs sit within a few hours of significant manufacturing clusters. If a supplier looks credible on day one, ask on day one whether you can visit before you fly home.
How they respond is worth noting and is a soft signal only. A supplier that arranges a visit readily is easier to take seriously, and one that cannot get you an answer all week is worth a second thought. But genuine factories refuse short-notice visits for entirely ordinary reasons: customer confidentiality, safety rules, audit schedules, a plant running someone else’s tooling that week. Refusal is not evidence of a problem, and agreement is not evidence of anything much either.
Do not over-read the visit itself. Arriving unannounced is neither realistic nor advisable, and a short lead time does not prevent a supplier from showing you a facility that is borrowed, shared, or simply not the one that would make your goods. A visit you arrange yourself tells you more than a visit they arrange for you, and neither replaces an audit by someone qualified to conduct one.
A short checklist to carry
- Photograph the whole business licence, including the QR code
- Note the Unified Social Credit Code for later lookup
- Read the business scope for production wording, and treat its absence as more telling than its presence
- Ask for the factory address and compare it with the registered address on the licence
- Record certificate numbers and issuing bodies, and note which schemes you can actually verify
- Ask whether samples are production or show pieces
- Compare the same product across six or more booths before forming a view
- Ask what went wrong on a recent order
- Request a factory visit before you leave the country
Take the same notes at every booth. Consistency is what makes the comparison work, and by day three you will not remember which supplier said what.
Keep the two tiers separate in those notes. Documents and registry records are checkable evidence, though a document can be forged and a registry entry can contain company-reported data. Everything else on this page narrows the field and nothing more.
