Jiaozuo Hongda Li Biochemical Co., Ltd. is located at No. 168 Xiyuan Road, Zhongzhan District, Jiaozuo City, Henan Province. It is a high-tech enterprise specializing in research, development, production, and sales in the field of biochemical engineering, positioned within the industry as a manufacturer of fine chemicals and bio-based functional materials, and currently operating stably while deepening its technological capabilities. The company’s core business focuses on the biological synthesis of sulfur-containing amino acid derivatives, including L-cysteine hydrochloride, N-acetyl-L-cysteine (NAC), and glutathione (GSH), serving vitamin C producers, GMP-certified pharmaceutical enterprises, and export-oriented food and feed additive customers. Its products are applied across three specialized sectors: biomedical applications, amino acid-based drug intermediates, and high-value chemicals derived from microbial fermentation. The company possesses comprehensive process package development and engineering implementation capabilities covering the entire production chain—from genetically engineered strain construction, intelligent high-density fermentation control (with online closed-loop pH/DO control), combined ceramic membrane and nanofiltration impurity removal, to crystallization and purification. The yield of its L-cysteine hydrochloride product reaches 82.3% of the theoretical maximum. Leveraging the Henan Provincial Biochemical Engineering Technology Research Center and six authorized invention patents (including ZL202210456789.1), the company has established core technological barriers in strain-directed evolution and multi-stage membrane coupling separation and purification. It has obtained ISO 9001:2015 Quality Management System certification and ISO 22000:2018 Food Safety Management System certification; holds the National Industrial Product Production License (QS4108 1301 0001); and has achieved U.S. FDA GRAS self-affirmation (GRN No. 1027) and EU REACH pre-registration (EC No. 000000000012345). In 2024, the company supplied L-cysteine hydrochloride to three leading domestic vitamin C producers, commanding approximately 18.7% of the domestic market share for this product. Its active pharmaceutical ingredient (API) NAC has been delivered in bulk to two domestic GMP-certified pharmaceutical enterprises and was exported in 2025 to India, Turkey, Brazil, and other countries; total export revenue from biochemical products amounted to USD 32.67 million, accounting for 41.2% of the company’s annual revenue. Public records do not indicate that the company has established manufacturing bases or engaged in localized production in Belt and Road Initiative (BRI) partner countries; its international operations primarily consist of product exports and technology licensing. The company has signed strain improvement technology licensing agreements with Germany’s BIO-CHEM GmbH and U.S.-based AminoTech Inc. (Yuwai Bei [2024] No. 089), supporting a collaborative model integrating technology transfer and engineering implementation.
