Not every seller on 1688 is the one who made the product. A large share of listings come from trading companies: businesses that buy from factories and resell at a markup. That markup goes into their pocket, not yours. Knowing how to filter down to the original factory gets you a lower base price, more flexibility on customization, and a direct line to the source when quality problems come up.
Two types of sellers, and why it matters
Factories and traders coexist on 1688, and from the outside they look nearly identical. Both have product photos, prices, and stated MOQs. The difference is where the goods actually come from.
A factory (工厂, gongchang) makes the product itself. It has machines, workers, and a production floor. The price they quote is the first price the product has ever carried, before it passes through any other hands. Factories are often less polished to deal with, but they can adjust specs, take OEM orders, and when a quality issue surfaces, you are talking to the people who caused it.
A trading company (贸易公司, maoyi gongsi) buys from multiple factories and resells. Traders typically carry a wider catalog, communicate faster, and are easier to deal with in a foreign language. But their price already has a margin layer built in, and any negotiation or product change requires them to loop back to the factory, which slows things down and reduces flexibility.
Neither is universally better. The point is to know which one you are buying from and understand the tradeoffs.
Signals that a listing is a factory
No signal is a guarantee from looking at a page alone, but several are reliable enough to act on:
The registered business name contains "厂" or "工厂". The character 厂 (factory) or the phrase 工厂 (factory/plant) in the official business registration is a meaningful signal. Traders typically register as 贸易公司 (trading company) or 供应链 (supply chain). The full registered name is usually visible in the store information section.
Product photos taken on a production floor. Photos showing machinery, assembly lines, raw material storage, or workers in a factory setting suggest self-production. Clean studio shots with lifestyle angles and multiple color options on a neutral background lean toward trader behavior.
Factory introduction video. Many genuine factories post a video walkthrough of their facility. This is harder to fake than static images.
Narrow and deep product range. A factory making stainless steel brackets will have many variants of stainless steel brackets, different sizes, different thicknesses, different finishes. A trader usually carries unrelated categories: brackets, leather bags, LED lights, all in the same store. A wide catalog with no apparent manufacturing connection is a consolidation signal.
Certifications and production licenses. Factories often post ISO certificates, production permits, or product test reports. These can be faked, but traders rarely bother faking an entire set of production-process documents.
Low MOQ flexibility. This sounds counterintuitive, but it is often a factory tell. Factories run production in batch runs and cannot easily break that structure for a small buyer. Traders, by contrast, are more flexible on quantity because they are selling from existing inventory.
How to find factory listings instead of waiting to stumble across them
Default 1688 search does not surface factories first. The algorithm favors sellers who pay for promoted placement and those with high transaction volume. Traders tend to do well on both counts.
A few active filtering approaches:
Use the "厂家" filter in search results. Below the 1688 search bar, there are supplier-type filter options. Selecting 厂家 (factory/manufacturer) instead of the default narrows the results list significantly.
Add "厂家直销" to your search term. This phrase means factory direct sales. It does not always improve results, but it is worth trying alongside your product keyword.
Look for the "工厂" tab in results. Some keywords on 1688 show a dedicated factory tab in the results view. Use it when it appears.
Read the "企业档案" (business profile) section on the store page. This section states the registered business type. Google Translate or a translation app handles it easily enough.
Cross-check the address against known production regions. Certain goods cluster geographically in China. Affordable apparel concentrates in Guangzhou and Hangzhou. Electronics cluster in Shenzhen. Ceramics in Jingdezhen. A store selling garments but registered in Shenzhen is worth a question.
When a trader is still the right call
Going direct to factory is not always better. Several situations make a trading company the more practical choice.
You are new and your volumes are small. Many factories carry minimum order requirements of several hundred to several thousand units before they will produce for you. When you are testing a market with 50 to 100 units, a trader's flexibility matters. You pay a higher unit price, but you limit your test-batch exposure.
You need variety across multiple product types. If you need 10 different SKUs from different factories, consolidating through a single trader simplifies operations considerably: one contact, one consolidation warehouse, one payment.
The factory refuses small buyers or will not deal in English. Some larger factories simply do not sell direct to foreign buyers, or they are not willing to spend time on small accounts. A trader bridges that gap.
You need value-added services. Pre-shipment inspection, custom packaging, Vietnamese secondary labels applied at the China warehouse: these are services that experienced traders can handle. Most factories are not interested in doing this work.
What the price difference looks like in practice
There is no single number that applies across all categories. A realistic working range: for standard competitive goods, factory prices typically run 10 to 20 percent below trader prices, depending on the product. For custom work (OEM, private label, packaging changes), the gap can be wider because traders add a coordination fee on top of the factory price.
On a small test batch of a few hundred dollars, the difference is modest. On a restocking order of a few thousand dollars or more, 15 percent savings on the goods cost is worth the extra time spent finding the right source.
What to do after you find a factory candidate
A listing that looks like a factory is not confirmed until you do a bit more work.
Chat and ask directly. Ask if they are a factory, what province the facility is in, and roughly how many units they produce per month. A real factory usually gives specific answers. Traders tend to be vague or pivot immediately to "we can provide this." Google Translate handles Chinese responses well enough to read the substance.
Order a sample before committing to a batch. Whether factory or trader, ordering one to three units before a first bulk run is the most basic quality check. Sample unit economics are bad because of the per-piece shipping cost, but it is far cheaper than discovering a defect problem after 500 units land in your warehouse.
Review transaction history and ratings. On 1688, store dashboards show on-time delivery rates, reported defect rates, and buyer feedback scores. These can be gamed, but a store with several years of history, thousands of transactions, and consistently solid scores is a meaningfully better signal than one registered three months ago.
Use a reliable order agent if you want an extra verification layer. Vietnamese order-agent services with 1688 experience can do supplier verification and pre-shipment inspection before goods ship. Fees typically run a few percent of order value. For a first order with a new supplier, that cost is reasonable insurance.
Bottom line
Finding factory-direct sources on 1688 is not a one-time task. Every new product category you enter requires running the same process again. But once you build a short list of proven suppliers, repeat orders become straightforward. Saving 10 to 20 percent on goods cost across consistent import runs adds up. More practically, you deal directly with the source, you have real negotiating leverage, and you are not dependent on a middleman whose quality controls and margins you cannot see.
