Gulf Resources manufactures and sells bromine, crude salt, chemical products, and natural gas extracted from natural brine deposits and wells in China. The company's core offerings include bromine—a halogen used in flame retardants, fumigants, water purification, dyes, and pharmaceuticals—and crude salt produced from evaporation processes, both sold to chemical manufacturers and other industrial customers within China through four wholly-owned subsidiaries. The business generates revenue through direct product sales, with bromine and crude salt representing the primary income streams and sales concentrated among a small number of large customers in Shandong and Sichuan provinces.
