Guangzhou Yinsu Flame Retardant Co.,Ltd

Guangzhou Yinsu Flame Retardant Co., Ltd. has been operating since 1996, giving them decades of experience in manufacturing fireproofing materials and polymer products — a strong foundation for reliability in high-risk applications. Being based in Guangzhou, one of China’s key industrial hubs, provides strong logistics access to major domestic and international markets. Their core products, including fireproofing materials and food additives, serve diverse industries, with food additives requiring strict safety compliance. The lack of verified work email, phone number, and business documents raises concerns about identity and legitimacy — buyers should request additional proof before placing large orders. While the company has a long history, the absence of verification signals a potential risk in due diligence. Buyers considering this supplier should verify credentials independently to ensure they are dealing with the correct entity. Having a clear product range helps buyers identify potential use cases, but trust must be confirmed through verification steps.
