Common Red Flags to Avoid
🚩 Warning signs of unreliable suppliers:
- Prices significantly below market average - Usually means inferior materials or hidden costs
- No physical address or factory photos - Likely a trading company posing as manufacturer
- Unwilling to sign NDA - Your designs could be sold to competitors
- Poor communication response time - If they're slow now, imagine after you pay
- No sample policy - Reputable factories always provide samples (paid or free)
- Vague answers about certifications - Ask for certificate numbers and verify online
The Sample Evaluation Process
Never place a bulk order without testing samples first:
Step 1: Request Samples
- Order 2-3 samples from different suppliers
- Pay for samples and shipping (shows you're serious)
- Specify exact requirements (color, logo, packaging)
Step 2: Test the Samples
Physical tests:
- Leak test: Fill with water, shake vigorously, leave upside down for 24 hours
- Insulation test: Fill with hot water (95°C), measure temperature after 6/12/24 hours
- Drop test: Drop from 1.5m height onto concrete (check for dents/leaks)
- Dishwasher test: Run through 10+ dishwasher cycles (check coating durability)
