Filtering reliable 1688 suppliers before your first order is the step most SEA operators skip, and it's why they end up posting in forums about getting scammed three weeks later.
Most guides on this topic give you a list of warning signs to watch for. That's useful, but it's backwards. You're reading the signals after problems have already started. This is the step before that: five checks you run before any money moves, taking 30 to 45 minutes per supplier. No years of sourcing experience required.
Scope note: this process applies to first orders with new suppliers. Established relationships you've run for six months work differently.
Recognizing Warning Signs Is the Reactive Approach
The standard advice is reactive by design. You learn a supplier is unreliable when wrong goods arrive, or when your deposit stops getting replies. By then you've already lost something, whether money, time, or a seasonal sales window.
The five steps below shift that. You exit bad relationships with 30 minutes spent, not $3,000 sunk into a bad bulk order.
Step 1: Read the Shop Profile in the Right Places
Three numbers matter on a 1688 shop page: how long the shop has been active (minimum three years), the actual transaction count behind the score, and positive feedback measured in absolute numbers, not just percentage.
A shop showing 98% positive sounds good until you see it's from 47 transactions. A shop at 94% from 4,200 transactions tells you something real.
Common trap: shops under two years old with suspiciously high scores. Low transaction volume plus a clean rating is a reason to look harder, not a green light.
Also check product category focus. A supplier specializing in one group, say phone accessories or children's clothing, is generally more trustworthy than a shop selling unrelated categories across the board.
Good signals: business license verification badge (营业执照 verified on the profile) and a Gold Supplier badge held across multiple consecutive years, not just the current one.
Step 2: Read Feedback Chronologically, Not by 1688's Default Sort
The platform defaults to showing the best reviews first. Change the filter to chronological before reading anything.
Focus on the last 90 days. You're looking for complaints about wrong items shipped, delivery running significantly longer than promised, and sellers going quiet after receiving payment.
When you find one-star reviews, check the shop's reply too. A supplier that responds clearly and takes ownership of the issue is showing you how they operate. One that ignores negative reviews or deflects is also showing you something. Skipping this chronological check is one of the most common mistakes operators make on first 1688 orders.
One more check: if the last 90 days show zero transactions, the shop may be dormant or recently reset under a new identity. Both are reasons to pause.
Step 3: Test Chat Behavior Before Mentioning Money
How a supplier treats you before you've committed reflects how they'll treat you after your transfer clears.
Send three specific questions: actual production lead time for a realistic batch size (not the headline figure), the real MOQ, and their process for handling defective goods including who pays return shipping.
Minimum acceptable response: a reply within two hours during Chinese business hours (8am to 6pm CST). Curt replies that skip the defect question are a red flag.
Extra test: ask for a short video of the production floor. Established factories send one without much friction. Shops without real production capacity often refuse, or send images that look pulled from other sources.
If they pass this, you're positioned to start negotiating price with your 1688 supplier once you're ready to move forward.
Step 4: Confirm Factory or Trader Before Going Further
Traders buy from factories and resell. They typically charge more and have less direct control over production quality. If you don't know which you're dealing with, you can't price the relationship correctly or hold the right party accountable.
The direct way to find out: ask for the business license (营业执照) and ask plainly whether they manufacture or source from other factories. Most suppliers answer honestly when the question is direct.
Cross-check on Alibaba International. Many 1688 factories also list there with more detailed verification. If the company name matches and the Alibaba profile shows verified manufacturing status, that's useful confirmation.
Traders aren't automatically bad partners. Some have strong quality control and competitive pricing. The problem is not knowing who you're working with. As you build a 1688 supply chain that doesn't depend on a single source, knowing exactly what each supplier is becomes critical.
Step 5: Order a Sample. No Exceptions for Attractive Pricing.
First order with any new supplier is a sample order. A low unit price on bulk means nothing if the goods arrive wrong.
Order enough to cover at least three to five variants. If the product comes in four colors, get at least three. Testing only the single best-looking SKU is not a representative check.
When the sample arrives, verify three things: actual material and finish versus listing photos, labeling and packaging against your stated requirements, and actual delivery time versus what was promised.
Pressure to close a bulk order before your sample arrives is a red flag. If the supplier keeps pushing you toward a larger commitment while your sample is still in transit, that behavior tells you what you need to know. Budget the sample cost into your initial testing plan. The guide to calculating 1688 import costs as a new operator covers how to account for this properly.
FAQ: Filtering 1688 Suppliers
What trust score is actually reliable on 1688?
Minimum three gold kettles (or equivalent tier) with at least 500 real transactions behind it. A high score with fewer than 100 transactions is a reason to be skeptical, not confident.
Should I order from a shop that's been open less than two years?
Not for high-value orders. If the price is compelling, place a small sample order and run the process at least twice before increasing volume.
How do I know if a 1688 shop is a factory or a trader?
Ask directly and request the business license. Cross-check the company name on Alibaba International. Most suppliers will tell you plainly if asked.
The shop isn't replying during business hours. Should I continue?
If there's no reply after four to six hours during Chinese business hours, move on. A supplier that can't respond before they have your money will not be faster after they do.
How many sample units do I need before committing to bulk?
Enough to cover three to five different variants. The goal is a broad enough test to surface problems, not minimizing what you spend on samples.
