FAQ

Q: Are you a real factory? 
A: We are a genuine manufacturer with our own production facility, not a trading company. You are welcome to visit our factory at any time. We guarantee you direct factory pricing, which usually saves you 20%-35% compared to buying from distributors.
 
Q: What is your delivery time? I often need urgent orders. 
A: For standard specifications, we keep a large stock of raw materials and semi-finished goods, allowing us to ship within 3-7 days. Even for custom orders, our streamlined production line keeps lead times short. We understand that downtime costs you money, so fast delivery is our standard service, not an extra cost.
 
Q: Can I get a sample to test the quality before a bulk order? What's your MOQ? 
Yes, we offer free existing stock samples — you only need to cover the shipping cost. For custom samples, a small setup fee applies, which is fully refundable with your first bulk order. Our trial-order MOQ is extremely flexible: as low as 1 piece for standard stock items, and 20 or 50 pieces for customized specs. This lets you test our quality and your market with almost no risk.
 
Q: What about your quality control and warranty? 
A: We perform 100% leak and micron rating testing on every batch before shipping. We are confident in our quality and provide a 12-month product warranty. If any issue arises, our after-sales team will respond with a solution within 24 hours. We always stand behind our products.
