Most ‘red flag’ lists only tell you to be careful. Careful how? Here are seven signals that something is off, each paired with the exact action that confirms or clears it.
1. Price far below market
If a quote is 30%+ under comparable suppliers, something is missing — cert, material grade, or the gas lift class. Verify: request the full spec sheet and the cylinder grade; a low price with a Class-2 cylinder isn’t a deal.
2. Trading company posing as factory
Many ‘factories’ are resellers. Verify: live video of the actual production line, and check whether the certs match the entity you’re contracting. 要打消你对’红旗’的顾虑，规格表、测试报告、同类订单的出货记录我都能给你备齐。开口我就整理。
3. Certificates that belong to someone else
A BIFMA cert for model A doesn’t cover model B. Verify: match the cert’s model number and scope to your exact build. 要打消你对’红旗’的顾虑，规格表、测试报告、同类订单的出货记录我都能给你备齐。开口我就整理。
4. Sample and mass-production mismatch
The sample is perfect; the container isn’t. Verify: tie acceptance to a pre-shipment inspection of the actual production batch, not the sample. 要打消你对’红旗’的顾虑，规格表、测试报告、同类订单的出货记录我都能给你备齐。开口我就整理。
5. Vague answers on specs
“It’s standard” is not an answer. Verify: demand written spec (cylinder class, base material, fabric rating). 要打消你对’红旗’的顾虑，规格表、测试报告、同类订单的出货记录我都能给你备齐。开口我就整理。
6. Pressure on payment terms
“Pay 100% now or lose the slot” on a first order is a classic. Verify: insist on deposit + inspection-linked balance. See our payment terms guide.
7. No third-party inspection allowed
A factory refusing SGS/TÜV inspection has a reason. Verify: walk away, or make inspection a contract condition. 要打消你对’红旗’的顾虑，规格表、测试报告、同类订单的出货记录我都能给你备齐。开口我就整理。
