1. Advertises zero service fees or ultra-low commission rates

• Red flag explanation: They earn secret kickbacks from factories by inflating unit prices and skipping strict QC. Your total procurement cost will end up far higher than using transparent fee-based agents.
• Warning behavior: Refuses to provide written service rate sheets and keeps talking about “free full sourcing support”.

2. Refuses to share business licenses, warehouse videos or physical office proof

• Red flag explanation: Likely an unregistered individual freelancer with no fixed local premises. Without their own warehouse, they cannot conduct on-site inspections or safely consolidate your goods.
• Warning behavior: Makes excuses to avoid live video tours of their Yiwu workspace.

3. Hides supplier information and bans direct communication with manufacturers

• Red flag explanation: They rely on middleman markups and factory rebates. If you contact factories directly, their hidden profit stream disappears.
• Warning behavior: Says “you don’t need to talk to suppliers, we handle everything” and never shares stall/factory names or contact details.

4. Vague, oral-only pricing with no formal written quotation

• Red flag explanation: They will add random surcharges for warehousing, photos, document processing or follow-ups after you place an order.
• Warning behavior: Avoids sending detailed written breakdowns of service fees, sampling charges and storage costs.

5. Skips standardized multi-stage QC and cannot provide inspection evidence

• Red flag explanation: They rush orders without strict quality checks to earn faster factory commissions. Defective goods will only be discovered after cargo arrives overseas.
• Warning behavior: Says “factories guarantee quality so inspection is unnecessary” or only sends blurry, incomplete photos instead of full AQL inspection reports.

6. Pressures you to pay full upfront payment instead of standard 30% deposits

• Red flag explanation: High risk of fund fraud or delayed production once they hold all your capital. Reputable agents follow the industry-standard partial deposit rule.
• Warning behavior: Offers a small discount only if you transfer 100% payment in advance.

7. Slow, irregular updates and ignores your follow-up messages

• Red flag explanation: They manage dozens of clients with no structured tracking system. You will miss critical production revisions and shipment deadlines.
• Warning behavior: Takes multiple days to reply, never sends scheduled production photos/videos, and fails to alert you to delays actively.

8. Avoids signing formal bilingual cooperation contracts

• Red flag explanation: No legal binding clauses for compensation, liability, delivery timelines or quality standards. You have no recourse if orders go wrong.
• Warning behavior: Claims “verbal agreement is enough” and delays drafting a formal service contract repeatedly.

9. Lacks relevant experience in your product category

• Red flag explanation: They cannot identify material flaws, compliance certification requirements or common manufacturing defects specific to your goods.
• Warning behavior: Cannot share matching past order cases or client references for your product niche.

10. Shifts all blame to suppliers when problems emerge

• Red flag explanation: They take zero accountability for miscommunication, missed inspections or coordination mistakes on their end.
• Warning behavior: Immediately blames factories for delays, wrong specs or defective products without proposing practical solutions like rework, replacements or partial refunds.

11. Overpromises unrealistic benefits

• Red flag explanation: Unscrupulous agents use impossible offers to lock your order first: extreme low prices, unlimited free warehousing, zero MOQs for all products.
• Warning behavior: Makes bold guarantees without written proof or clear terms attached.
