The minimum order quantity (MOQ) varies by product size. For example, the MOQ for 20mm pipes is 5000 meters, while for 160mm pipes, it is 300 meters. As for regular pipes and pipe fittings, we have sufficient inventory, so there is no MOQ requirement for them.

Typically, the delivery time is 15 days, but the specific timeline still depends on the order list and the factory's recent production schedule.

When quoting, we will confirm the transaction terms with you, such as FOB, CIF, CNF, or other applicable terms. For mass production, we usually require a 30% advance payment first, and the balance shall be paid upon presentation of the Bill of Lading (B/L). Our main payment method is T/T (Telegraphic Transfer), but L/C (Letter of Credit) is also acceptable.

We have a CNAS-accredited laboratory (recognized by the national authority). Every batch of goods will undergo sampling tests. During production, we also conduct regular inspections every 2 hours to measure and check relevant data. Meanwhile, our quality inspection department will perform quality checks at different time intervals.
