Ningbo Yinzhou Industry Co., Ltd

Ningbo Yinzhou Industry Co., Ltd. is typical of many Chinese suppliers in offering a wide range of promotional and cooling products, from hot/cold packs to cooler boxes and eye masks. Being based in China gives them strong access to manufacturing and logistics networks. Founded in 1999, they have over two decades of experience, which suggests stability and familiarity with international buyer needs. However, the lack of verification on phone, work email, and business documents raises a red flag — buyers should verify these details before placing large orders. Without verified contact points, it's harder to confirm responsiveness or resolve issues quickly. This is common among smaller suppliers who may not prioritize full verification, so buyers should request additional proof or a meeting to assess credibility.
