Daye Tengfei Sponge Factory, Changzhou, China

Daye Tengfei Sponge Factory, Changzhou, China has been operating since 1995, giving it nearly three decades of experience in sponge production — a strong indicator of stability and market presence. The company specializes in sponge products, which are commonly used in construction, insulation, and industrial applications, making it a potential supplier for buyers in those sectors. However, no verification of work email, phone number, business documents, or account email has been confirmed — this raises red flags about identity and legitimacy. In international trade, unverified profiles can lead to fraud or miscommunication, so buyers should request additional proof before placing large orders. Being based in Changzhou, China, places it near major manufacturing hubs with strong logistics networks, which could support efficient production and delivery. Still, without any verification, the risk of dealing with a fake or inactive business remains high.
