Dual-Base R&D & Production of Veterinary Raw Materials, Lingyun Pharmaceutical Serves the Global Animal Health Market

Nestled in Jintan District, Changzhou City, Jiangsu Province, at the heart of the Yangtze River Delta, a company that has quietly cultivated its expertise in veterinary active pharmaceutical ingredients (APIs) for over two decades—Jiangsu Lingyun Pharmaceutical Co., Ltd.—is conquering global markets with its formidable technological prowess and exceptional product quality.

Corporate Profile: A High-Tech Enterprise with a Dual-Site Strategy

Founded in 2000, Jiangsu Lingyun Pharmaceutical Co., Ltd. is a national high-tech enterprise specializing in the R&D, manufacturing, sales, and integrated services of internationally novel veterinary APIs (including chemically synthesized drugs and bio-fermentation semi-synthetic drugs). The company's headquarters and R&D center are located in Jintan, Changzhou, with a wholly-owned subsidiary production base in the Huai'an Industrial Park, Jiangsu Province. The total site area covers 300 mu (approximately 20 hectares), with a workforce of over 400 employees. Since 2007, the company has obtained national veterinary GMP certification and has established the "Jiangsu Provincial Bio-Veterinary Drug Engineering Technology Center." It has been honored with titles such as "Provincial Specialized and Sophisticated SME" and "Provincial Gazelle Enterprise," and has accumulated 51 national patents, including 23 invention patents. Adhering to the development philosophy of "Integrity, Innovation, Green, and Health," the company's products are exported to more than 20 countries worldwide. With over 20 years of deep commitment to the poultry and companion animal health sectors, Lingyun Pharmaceutical stands as a stable core API supplier in the international animal health industry.

Star Products: Breaking Technological Barriers and Filling Domestic Gaps

Guided by the creed of "Technology-Driven, Innovation-Powered," Lingyun Pharmaceutical has successfully cracked the core technologies of numerous internationally advanced APIs. Its flagship product, Toltrazuril—a broad-spectrum anticoccidial API whose original technology was once Nobel Prize-honored—was successfully synthesized by Lingyun through all 26 reaction steps after the patent expiration. The company now holds over 50% of the domestic market share, with the majority of production exported overseas. Another key product, Fipronil, used for deworming in dogs and cats, has seen Lingyun become the first domestic manufacturer to obtain the API production approval, with only a handful of companies in China possessing the capability to produce it. Furthermore, the company boasts a portfolio of high-tech products at internationally advanced levels, including Decoquinate, Tulathromycin, and Moxidectin.

1. Anticoccidial APIs (Core Portfolio)

Toltrazuril, Decoquinate, and Ponazuril—featuring high purity and low toxicity—are widely used for poultry coccidiosis prevention and control, and are ideally suited for formulation production in large-scale farming operations.

2. Macrolide Anthelmintic and Antibacterial APIs

Tulathromycin, Moxidectin, Doramectin, Selamectin, Milbemycin Oxime, Tiamulin, and Tilmicosin—covering full-spectrum applications ranging from poultry respiratory antibacterial treatment to internal and external deworming for dogs and cats.

3. Topical Ectoparasiticide APIs

Fipronil—a core ingredient for pet deworming, offering stable insecticidal efficacy, and a mainstream procurement category among pet pharmaceutical companies.

4. Cephalosporin Veterinary Antibacterial APIs

Ceftiofur, Cefquinome, and Cefovecin—targeting bacterial infections in poultry and livestock, with stringent impurity control, suitable for high-end veterinary formulations.

5. Cosmetic Functional Ingredients

Tetrahexyldecyl Ascorbate (THDC)—used as an antioxidant ingredient in skincare products, expanding into the diversified fine chemical application sector.

Industry Advantages: International Certifications and Global Giants' Favor

1. Dual-Site Synergistic Production Capacity with Parallel Fermentation and Synthesis Lines

The Jintan base focuses on R&D, pilot-scale trials, and high-end custom orders, while the Huai'an Weil-ing subsidiary handles megaton-scale mass production. The chemical synthesis and bio-fermentation production lines operate independently in segregated zones to prevent cross-contamination. The company is capable of fulfilling both long-term bulk orders from major overseas formulation manufacturers and offering small-batch R&D samples and customized repackaging, demonstrating exceptional flexible supply capabilities. Leveraging the logistical advantages of the Yangtze River Delta ports, domestic distribution is highly efficient, and international trade procedures—including customs declaration, commodity inspection, and full set of export documentation—are handled seamlessly.

2. Provincial-Level Engineering R&D Platform with High International Certification Barriers

The company has built a provincial-level bio-veterinary engineering technology center, independently mastering core patented processes in fermentation purification and chemical synthesis. Its products have obtained veterinary GMP and ISO 9001 quality management system certifications, with four products having secured U.S. FDA import eligibility, while also complying with EU veterinary drug access standards. This eliminates the need for redundant testing in export destinations, significantly reducing customers' compliance costs. The technical team can customize product purity, particle size, and impurity profiles based on client requirements, offering bespoke API synthesis and development services.

3. Full-Process Closed-Loop Quality Control with Exceptional Batch-to-Batch Consistency

An end-to-end, multi-tiered quality inspection system has been established, covering raw material intake, fermentation/synthesis, purification, and finished product dispatch. Equipped with advanced precision instrumentation including HPLC and mass spectrometry, the company maintains long-term retained samples for each batch with full traceability. Strict controls are enforced on heavy metals, related substances, and microbial limits, resulting in minimal batch-to-batch variation—a key factor that has earned long-term repurchase commitments from leading animal health companies both domestically and globally.

4. Dual-Channel Global Services with Multilingual Foreign Trade Support

For the domestic market, the company provides rapid sample delivery and formulation technical guidance; for overseas markets, a dedicated multilingual foreign trade team offers full-process support, from order tracking and logistics to after-sales quality issue resolution. Online and offline channels are fully integrated, ensuring efficient responsiveness to diverse customer needs worldwide.

Corporate Development Vision

Looking ahead, Jiangsu Lingyun Pharmaceutical Co., Ltd. will continue to deepen its presence in the high-end veterinary API sector, persistently iterating green, low-carbon fermentation and synthesis processes, expanding new product categories in pet-specific and premium poultry antibacterial/anthelmintic segments, and upgrading R&D and quality control hardware facilities. The company will further strengthen industry-academia-research technological innovation, optimize its domestic and international market footprint, and, backed by its dual-base production capacity and comprehensive international accreditations, strive to become a leading domestic and globally trusted benchmark enterprise in animal health APIs—partnering with stakeholders across the global animal health industry chain for mutual growth and shared success.
