Tianjin Congsa International Trade Co., Ltd.

Tianjin Congsa International Trade Co., Ltd. has been operating since 2003, giving them long-term experience in handling chemical and glass products across international markets. Their core products — sodium sulfide, float glass, sulfate, soda ash, and pepper — are widely used in manufacturing and industrial processes, making them a relevant supplier for buyers in construction, chemicals, and food processing. Being based in China, a major global producer of glass and chemicals, provides strong supply chain access and cost efficiency. However, none of their key verification points — phone, work email, or business documents — are confirmed, which raises concerns about identity and legitimacy. Buyers should request additional proof before placing large orders or sharing sensitive requirements. Without verified contact details, it's harder to confirm real-time communication or respond to urgent inquiries. A verified account email is present, but it's not enough to fully validate the business.
