The unified social credit code on a Chinese company’s business license tells you in 18 digits whether you’re dealing with a factory or a trading company — and most overseas buyers never check it. Position 9 to 17 of that code encodes the company’s main industry classification. Real manufacturers carry codes starting with 3 (industrial production). Trading companies carry codes starting with 5 (wholesale and retail) or 6 (logistics). It takes 90 seconds to look up and most fake “factory direct” suppliers fall apart on this one check alone.

This article is not about whether trading companies are bad. They aren’t. Some of the most reliable suppliers I’ve worked with for clients in Almaty, Tashkent, and Lagos are large trading houses with strong factory networks. The problem is when a trading company sells itself as a factory, charges you the factory’s margin plus its own, and disappears the moment a quality dispute starts. That’s the pattern this article is built to catch.

Below are eight verifiable signals you can run through in 90 seconds before your second call with any Chinese supplier, two specific traps I see new buyers fall into every month, and a clear framework for when a trading company is actually the right choice over a direct manufacturer.

Why “Factory Direct” Is Worth Verifying — Even If You Trust Your Contact

A buyer in Karaganda paid 12% above market for a batch of mining ventilation fans last year because the “Shandong factory” he had been negotiating with for three months was actually a trading company in Hangzhou subcontracting to a real manufacturer 800 kilometers away. He found out when warranty repairs required parts the supposed “factory” couldn’t produce because they had never made the unit in the first place. The trading company quietly went silent. The real manufacturer had no record of him as a customer.

This pattern repeats across categories. Construction machinery, electrical panels, agricultural equipment, building materials — anywhere the Chinese export market is large enough to support a layer of intermediaries, you’ll find trading companies marketing as factories. Most of them aren’t trying to scam you. They’re trying to win the order. But the consequences when something goes wrong are real:

• You pay both margins. A trading company typically adds 8 to 18% on top of the factory’s price. If the factory had a 5% margin, your total markup is closer to 25%.
• Warranty disputes have no leverage. When a defect appears, the trading company says “we’ll talk to the factory.” The factory says “we never sold to this buyer.” You sit between two parties, both of whom can walk away.
• Customization requests get distorted. Every spec change goes through translation twice: your English to the trading company’s Chinese, the trading company’s Chinese to the factory’s local dialect or production team. Tolerances drift, materials get substituted, and you find out at FAT.
• Lead times become unpredictable. The trading company quotes you a delivery date based on what the factory promised. The factory’s actual queue is invisible to both of you.

None of this means you should refuse to work with trading companies. It means you should know which one you’re dealing with, and price the relationship accordingly. A trading company that openly says “we don’t manufacture, we represent factory X” is a different proposition from one that puts a stock photo of a factory floor on its website and claims it as theirs.

The 8 Signals That Tell You Factory vs Trading Company in 90 Seconds

These signals run from cheapest and fastest (90 seconds with a browser) to deepest (a video call or an in-person visit). Run the first four on every new supplier before you even reply to their second message. Run the next four before you place an order over $10,000.

Signal 1: The Industry Code on the Business License

Every Chinese company has a unified social credit code (统一社会信用代码), an 18-character identifier printed at the top of the business license. The third character ranges from 1 to 9 and encodes the company’s category of registration. The next nine characters encode the administrative region and a sequential number. The industry classification is not actually in the code itself — it’s in the registration record on gsxt.gov.cn.

What you want to verify on the license:

• Registered scope of business (经营范围): A real manufacturer’s scope reads something like “manufacturing of hydraulic excavator components; metal stamping; assembly of construction machinery; import and export.” A trading company’s scope reads “wholesale of construction machinery; technology import and export; supply chain management services.” If “manufacturing” or “production” (生产 / 制造) does not appear early in the scope, you are not looking at a factory.
• Registered capital (注册资本): Real manufacturers in heavy industries typically have registered capital of 5 million RMB or more, often 10 to 50 million. Trading companies often register at 500,000 to 1 million RMB. This isn’t a hard rule — some real factories under-register on purpose for tax reasons — but a “factory” registered at 100,000 RMB capital making industrial machinery is a strong negative signal.
• Date of incorporation: Trading companies are easy to spin up; the average age of a trading company in China is under 5 years. Real factories, especially in industries like construction equipment or electrical, are usually 10+ years old because the capital investment in production lines takes years to amortize.

Ask the supplier to send you a clear photo of their current business license in the first three messages. If they delay, decline, or send something blurry, that’s your answer.

Signal 2: The Address — Industrial Park vs Office Building

Look up the registered address on Baidu Maps or Google Maps satellite view. This takes 60 seconds.

• A factory address points to an industrial park, a freestanding production complex, or a building inside a manufacturing zone with visible loading docks and a parking lot for trucks.
• A trading company address points to a high-rise office building, a coworking space, or a residential-commercial tower.

This is not a perfect signal — some legitimate manufacturers have separate sales offices in tier-1 cities, and the address on the business license might be the sales office rather than the plant. But if the address is the only address they ever give you, and it’s a 30th-floor office in downtown Shanghai, you are not buying directly from a factory.

A trick that works: ask for two addresses, the registered office and the production facility. A real factory will give you both within hours. A trading company will either refuse, give you the same address twice, or claim the production facility is “confidential.”

Signal 3: VAT Invoice Type

A real Chinese manufacturer is almost always a “general taxpayer” (一般纳税人) and issues a special VAT invoice (增值税专用发票) at 13% for industrial products. The export tax rebate system requires this — without the special VAT invoice from the manufacturer to the exporter, no rebate can be claimed.

What this means for you:

• If the supplier is the actual exporter and a real manufacturer, they will be happy to confirm general taxpayer status and the 13% VAT rate.
• If the supplier is a trading company, they need to source the special VAT invoice from the factory upstream. They can still do this — that’s the normal pattern — but they’ll often be vague about the rebate calculation because they’re capturing part of the rebate as their margin.
• A “factory” that issues only the ordinary VAT invoice (增值税普通发票) at 3% is either a small workshop without general taxpayer status, or a trader masquerading as a factory.

Ask directly: “Are you the export entity, or do you use an export agent? What is your VAT rate? Can you issue a 13% special VAT invoice?” Real manufacturers answer these in one paragraph. Traders dodge or redirect.

Signal 4: Export License and Customs Records

Two government-run databases tell you whether a company has actually exported anything, and to whom:

• Customs registered enterprises database (海关进出口企业备案查询): Lists every company with an active customs export registration. If your supplier isn’t in it, they cannot legally export under their own name.
• Public customs declaration records: Aggregators like Panjiva, Import Genius, or 52wmb.com show export volumes, destination countries, and HS codes by exporter. For machinery suppliers claiming “we ship 50 containers a month to Russia,” you can check whether their customs records actually show this.

A real Chinese manufacturer with international clients will have a visible export footprint over the last 24 months. A trading company will too, but the pattern looks different: a trading company exports a wide variety of HS codes across many product categories, while a factory’s exports cluster around 3 to 6 HS codes within their specialty.

This check kills the most common scam: the “factory” that has been in business for two years and somehow claims it ships to 40 countries, but whose customs records show 200 kg of export volume total.

Signal 5: Factory Photos and EXIF Metadata

Anyone with a phone can take a factory photo. The question is whether the photos they send you are theirs.

• Reverse image search every “our factory” photo on Google Images or TinEye before your second call. Trading companies recycle stock photos and even photos from competing real factories. If the same image appears on a dozen other Alibaba listings, it’s not theirs.
• Ask for raw photos with EXIF metadata (the GPS coordinates, camera, and timestamp embedded in the file). Real factories that send you photos taken on a recent walk-through can usually send the raw .jpg straight from a phone, EXIF intact. If they only send compressed images or stripped-EXIF copies, you can’t verify location or recency.
• Ask for a 30-second video walk from the office to a specific machine, narrated by their sales contact. A trading company without a real factory will improvise — they’ll send a video filmed by “our QC team last month” or “our partner factory” with no narration. A real factory rep walks the camera through the door and points at things.

I’ve had a trading company in Yiwu send me a “factory tour video” that was actually filmed inside a different company’s plant in Ningbo. The giveaway was a logo on a calibration sticker visible for two seconds on a press machine. Reverse-imaging the logo led me to the actual manufacturer’s website, where I confirmed the trader had no relationship with that factory at all.

Signal 6: Live Video Walk-Through

The single highest-information action you can take with a Chinese supplier in 30 minutes is a live video call from inside their facility. Not a pre-recorded video. Not a Zoom meeting from their office. A WeChat video call where the salesperson walks you from the entrance, through the production line, into the QC lab, and back to the office.

What to look for:

• Continuity: One unbroken shot, not a series of clips. Cuts mean they’re filming sections separately to hide gaps.
• Background detail: Real workers in uniforms with consistent branding. Calibration stickers on machines with recent dates. Material storage matching the products they claim to make.
• Responsiveness: Ask them to show you a specific machine you discussed in your spec. A real factory rep walks over and shows it. A trader stalls, says “that line is closed today,” or pivots to another topic.
• Audio: Production noise should be audible and continuous. A “factory” that’s eerily quiet during business hours is either a showroom or someone’s office with stock production sounds removed.

I’ve had factories pass and traders fail this test in the first 90 seconds. The traders fail because they can’t physically be where they claimed to be.

Signal 7: Export Tax Rebate Filing History

This is the most technical signal but also the hardest to fake. China’s export tax rebate system (出口退税) requires the exporter to file detailed records with the customs and tax authorities for every export shipment. The rebate is paid to the named exporter, which is the entity on the customs declaration.

For machinery, electrical equipment, and most B2B industrial products, the rebate ranges from 9% to 13% depending on the HS code. This is a major source of cash flow for real exporters and a major leverage point for buyers.

What to ask:

• “On a CIF Almaty $50,000 order, what’s the VAT rebate amount you expect to receive, and how does that affect your quote?”
• “Can you send a redacted copy of a recent export tax rebate filing for a comparable shipment, with customer names and amounts blacked out?”

A real factory or exporter will quote you the rebate to the kuai. They live and die by this cash flow. A trading company will be vaguer — partly because they may be sharing the rebate with the factory upstream, partly because they may not even file the rebate themselves. If a supplier can’t articulate the rebate mechanics for their own product, they almost certainly aren’t the direct exporter.

For deeper background on how to use the rebate as a negotiation lever, see our breakdown on how to verify Chinese suppliers and read the 2026 red flags.

Signal 8: The Customs Broker They Use

Every Chinese exporter has a customs broker (报关行) handling the declaration paperwork. Brokers tend to specialize by category and region. A broker that handles excavator exports in Qingdao port has decades of experience with HS codes 8429 and 8431, knows the EAC documentation requirements for Russia and Kazakhstan, and has relationships with the local customs office.

Ask your supplier: “Which customs broker do you use, and at which port?” A real factory exporter answers in one sentence. A trading company may not even know the answer because they outsource to their own forwarder, who then picks the broker.

If you can, look up the broker’s record on the same customs aggregator databases mentioned in Signal 4. A broker that has handled hundreds of similar exports in your category over the last two years is a confirming signal. A broker who shows up only in this one supplier’s records is a warning sign.

2 Specific Traps That Catch Even Careful Buyers

After running through the eight signals above, you’ll catch most fake “factories.” But two traps are designed to defeat exactly the signals I just listed. These are the ones to watch for.

Trap 1: The Borrowed Showroom

Some trading companies rent or borrow a section of a real factory’s facility — a corner of the loading dock, an unused showroom, a meeting room near the main entrance — and conduct customer visits and video calls from there. You see machinery in the background, you hear production noise, you meet “the factory team” (actually trading company sales staff). The deception is physical, not just digital.

How to catch it:

• Cross-check the registered address against the visit address. If they ask you to “visit our other facility” rather than the address on the license, that’s the first signal.
• Ask to see the production line that will make YOUR order specifically. A borrowed showroom can’t escort you to a specific assembly line dedicated to your product because it doesn’t exist.
• Request to meet the production manager, not the sales manager. Production managers know their own people and their own machines. A trader at a borrowed showroom can produce a “sales manager” but stalls when you ask for the production lead.
• Ask for the worker shift schedule and walk through during shift change. A real factory has hundreds of workers moving between buildings at 6 PM. A borrowed showroom has the sales team and maybe two real factory workers planted as props.

A buyer in Aktobe nearly placed a $180,000 transformer order with a “Zhejiang factory” that was actually a Shanghai trading company conducting visits at a partner factory’s empty meeting room. The catch came when our team requested to see the winding department mid-shift on a random Tuesday morning. The trading company offered three rescheduling dates over two weeks. We walked away. The real factory upstream confirmed they had no relationship with the trader and would have been willing to quote directly.

Trap 2: The “Self-Operated Factory” Registration

This trap is more sophisticated. A trading company sets up a second legal entity that registers “manufacturing” in its business scope, rents a small workshop (or even just an industrial address), and uses this as proof of being a factory. The original trading company funnels orders to the “factory” entity on paper, which then subcontracts production to actual manufacturers. The buyer sees a manufacturing license and assumes everything is direct.

The give-aways:

• The “factory” was incorporated within the last 2 to 3 years. Real manufacturers don’t pop into existence overnight in heavy industries.
• The registered capital is small for the scale of operations claimed — a “factory” registered at 500,000 RMB capital but claiming to ship 100 containers a month is mathematically improbable.
• The factory address is a small lot in an industrial park, not a complex with multiple buildings. A 500 square meter workshop cannot produce industrial equipment at the volumes they claim.
• The export volumes in public customs records are inconsistent with their claimed capacity. Look at Signal 4 again — if their customs export weight is 200 kg over 18 months, they aren’t manufacturing excavators at scale.
• No general taxpayer status on the “factory” entity. Real exporters need general taxpayer status to claim the 13% rebate. If the manufacturing entity only has small-scale taxpayer status, it’s not actually running an industrial operation.

Both traps share a common defeat: a request to visit unannounced, during normal production hours, with a specific list of things you want to see. Trading companies running these traps cannot accommodate unannounced visits because the showroom is borrowed and the factory is a shell. A real manufacturer welcomes them.

When a Trading Company Is Actually the Right Choice

Half of this article has been about how trading companies disguise themselves as factories. The other half deserves to say: some trading companies are excellent suppliers, and there are conditions under which a trading company is the smarter choice.

When a good trading company wins over a direct factory:

• You need 5 different products from 5 different categories. A trading company that handles all 5 can consolidate ordering, inspection, and shipping into one container, with one invoice and one set of documents. Going direct to 5 factories means 5 contracts, 5 QC visits, 5 shipping bookings, and a coordination nightmare for a single small import.
• Your order is too small for the factory to take seriously. A factory with a 500-unit minimum order quantity isn’t going to give you priority on a 50-unit order. A trading company that aggregates demand across 10 buyers can negotiate a slot for your 50 units inside someone else’s larger production run.
• You don’t have local language or regulatory capacity. A trading company that has been exporting machinery to Russia for 15 years knows the EAC documentation, the Belarusian customs preferences, the Kazakh banking quirks. A factory that’s never shipped to Central Asia will learn these on your dime.
• You need credit terms. Real factories typically demand 30% deposit and 70% before shipping. Trading companies can sometimes extend LC at sight or even 30-60 day credit because they’re carrying the cash flow for you against their relationship with the factory.
• You need a single throat to choke for warranty. A trading company that’s been your supplier for 10 years and wants to keep your business will fix problems at their own cost to protect the relationship. A direct factory will quote you the price of replacement parts and ship them ex works.

The honest framing is: a transparent trading company that says “I’m not a factory, I represent factory X, here’s my margin and here’s what you get for it” is often better than a sketchy “factory” that’s secretly a trading company adding hidden margin. The bad case isn’t trading companies — it’s lies about what role the supplier plays.

For machinery buyers in Central Asia specifically, working with our team often means we play the trading company role transparently: we source from factories in Shandong, Hebei, or Jiangsu, we handle EAC and customs, we consolidate shipments, and we absorb the warranty risk. The buyer pays a clear agent fee and knows exactly which factory made the equipment. That’s the legitimate version of the trading-company-as-intermediary model. The illegitimate version is the same role with all the value-add invisible.

How XILINK Verifies Suppliers for Central Asian Buyers

Our team in Jiangsu has been verifying Chinese suppliers for buyers in Kazakhstan, Russia, Uzbekistan, and Africa for over 10 years. The eight-signal framework above is the short version of what we run before any client commits to a factory. The longer version includes pre-contract audits, in-line production QC, and final inspection before container loading.

For buyers who want to source directly from a verified factory: we conduct factory audits across China and produce a 20 to 35 page report with photos, document verification, and a go / no-go recommendation. Pricing starts at $400 for a single-day audit. For buyers who want us to handle the full procurement, the factory verification is included as part of our agent service. Either way, the goal is the same: you know exactly which legal entity made your equipment, what their real production capacity is, and what your warranty rights look like in writing.

For the complete process, see our factory audit guide for Central Asian buyers and our pre-contract audit framework for Chinese suppliers.

FAQ

How can I tell if a Chinese supplier is a factory or a trading company in just one message? Ask three questions in your first reply: “Can you send a clear photo of your current business license? What is your factory address, and is it the same as your registered office? Are you a general taxpayer issuing 13% special VAT invoices?” A real factory answers all three in one paragraph with attachments. A trading company will dodge at least one, or will redirect to a different topic.

Is it always better to buy from a factory directly? No. Direct purchases make sense when your order is large enough that the factory takes you seriously (typically $50,000 and up for one product category), when you have language and regulatory capacity locally, and when you have time to manage factory relationships directly. For small orders, multi-category sourcing, or buyers without China experience, a transparent trading company or a sourcing agent is often cheaper and faster in total cost.

How do I check a Chinese company’s business license online? Go to gsxt.gov.cn — the National Enterprise Credit Information Publicity System. Enter the company’s Chinese name or unified social credit code. The system will show registration status, scope of business, registered capital, legal representative, and any operational anomalies. Third-party tools like Tianyancha (tianyancha.com) and Qichacha (qcc.com) provide more detailed history including changes of legal representative, equity changes, and litigation records.

What is a unified social credit code and what should I look for in it? It’s an 18-character identifier on every Chinese business license, like a tax ID. You don’t decode the digits directly — you use it to look up the company on gsxt.gov.cn. What you want from the lookup is the scope of business (经营范围), which tells you whether the company is registered for manufacturing (生产 / 制造) or wholesale trade (批发).

Can a trading company actually offer factory prices? Almost never on the same product. A real factory’s cost includes labor, materials, and overhead, with a typical margin of 5 to 8% for machinery. A trading company adds 8 to 18% on top. The trader can only offer “factory prices” if they’re either lying about being a trader, taking a temporary loss to win the relationship, or selling overstock at clearance. For long-term sourcing, the price gap is real.

What’s the fastest way to verify a Chinese factory if I’m not in China? Run all eight signals above before your second call: business license check on gsxt.gov.cn, address satellite view, VAT taxpayer status confirmation, customs export records lookup, reverse image search on factory photos, live video walk-through, export tax rebate questions, and customs broker identification. This takes about two hours total and catches most disguised trading companies. If the order is large enough to matter (over $30,000), pay $400 to $900 for a one-day on-site audit by a Chinese auditor before signing the contract.

Do real Chinese factories ever use trading companies as their international sales arm? Yes, this is common and legitimate. Large Chinese factories often partner with experienced export trading companies (foreign trade SOEs or established private trading houses) to handle international sales, EAC certification, and logistics. The key is transparency: a legitimate arrangement is openly disclosed, the trading company introduces themselves as the export representative for factory X, and you can verify the relationship by contacting the factory directly. The illegitimate version is a trader pretending to be the factory itself.

How long does it take to verify a Chinese supplier from start to finish? For most buyers: 90 seconds for the first four signals (license, address, VAT, customs records), 30 minutes for the live video walk, and 24 to 72 hours for a third-party on-site audit if the order justifies it. Total: under a week to know exactly who you’re dealing with. The cost of skipping verification on a $50,000 order can be the entire order value when things go wrong. The cost of doing verification properly is under 1% of the order.
