Highsun Holding Group (HSCC), also known as 恒申集团, is a leading Chinese multinational enterprise in the chemicals, chemical fibers, and advanced new materials sectors. Founded in 1984 in Fujian Province starting with a single nylon rope production line, the company has developed into the world’s largest producer of caprolactam (CPL), a critical precursor for polyamide 6 (PA6) and related polymers.
HSCC maintains a fully integrated industrial chain from basic chemical raw materials through polymerization, fiber spinning, and high-end materials. It operates four major industrial bases centered in Fuzhou (Fujian), with additional facilities in Nanjing (Jiangsu), Xinhui (Guangdong), and Maastricht (the Netherlands), encompassing 31 manufacturing centers. The group serves customers across more than 60 countries and regions worldwide.
With over 14,000 employees, HSCC ranks among China’s Top 500 Enterprises. Its portfolio includes caprolactam and ammonium sulfate production, polyamide fibers and chips, engineering plastics compounding, electronic specialty materials, fragrances and flavors, and circular economy initiatives such as chemical recycling. The holding company structure oversees numerous subsidiaries and has expanded through acquisitions, including Fibrant’s global caprolactam operations, while pursuing sustainability and new energy applications.
In October 2026, HSCC signed a non-binding memorandum of understanding with BASF to explore a potential 50:50 joint venture combining selected European PA6 value-chain activities.
