Tanhong Import and Export Co., Ltd. is a comprehensive high-tech enterprise integrating biological raw material R&D, fine organic synthesis, standardized production and cross-border import and export trade. For many years, we have been deeply engaged in the fields of life sciences, fine chemical industry and biological scientific research raw materials. Our main products cover research-grade peptides, small-molecule biochemical reagents, halogenated alkane organic intermediates, enzyme inhibitors and cell experimental research raw materials. We specialize in providing high-purity and high-stability in vitro laboratory research materials and customized synthetic export services for global university laboratories, scientific research institutions, biopharmaceutical enterprises and fine chemical R&D units, with business covering more than 50 countries and regions worldwide.
Relying on our own modern production base, we have built a full closed-loop industrial chain from raw material procurement, precise synthesis, purification and lyophilization, aseptic subpackaging, quality inspection to cross-border export. Different from traditional trading companies, we have independent R&D and large-scale production capacity. Located in a standardized industrial park, our production base operates in strict accordance with biochemical production specifications and builds a 100,000-class clean production workshop. Independent partition and physical isolation of production, R&D, quality inspection, warehousing and packaging areas completely avoid cross-contamination, ensuring the purity and stability of each batch of products.
Standard Factory & Workshop Environment
The factory has a complete modern production system with independent synthesis reaction workshop, purification workshop, vacuum lyophilization workshop, aseptic subpackaging workshop, finished product packaging workshop and special hazardous waste treatment area. The whole workshop adopts dust-proof, anti-corrosion and anti-static professional flooring, sealed purification windows and automatic HVAC constant temperature and humidity fresh air circulation system, maintaining a dust-free and sterile production environment all year round, which fully meets the high-precision preparation requirements of peptides and fine organic intermediates. All staff must complete three-stage air shower disinfection and wear full sterile protective equipment before entering the production area for standardized operation.
We are equipped with a full set of high-end industrial production equipment, including automatic solid-phase peptide synthesizers, industrial HPLC purification systems, high-speed centrifuges, vacuum freeze dryers and closed aseptic subpackaging equipment. All equipment is made of food and pharmaceutical-grade stainless steel with regular calibration and maintenance records to ensure stable and controllable reaction conditions. We can stably produce high-purity research raw materials with a purity of 98%-99% to meet the needs of various high-end scientific research experiments.
Independent R&D and QC Laboratory
We have built a 2000㎡ professional R&D and testing laboratory with independent research center and authoritative quality control system. Equipped with mass spectrometers, high-performance liquid chromatographs, UV spectrophotometers, moisture testers, heavy metal detectors and other precision testing instruments, we can independently complete full-item detection including component analysis, purity verification, impurity screening, stability testing and molecular weight confirmation. All raw materials, semi-finished products and finished products adopt the triple quality inspection standard of incoming inspection, in-process sampling inspection and finished product full inspection. Each batch of products is attached with official COA, HPLC chromatogram, MS spectrum and MSDS documents. All test data is archived for a long time with full traceability, complying with international laboratory testing standards and customer factory audit requirements. We also support customized testing services.
Classified Constant Temperature Warehousing System
To meet the diverse storage requirements of scientific research raw materials, we have built a multi-functional classified warehousing system, including normal temperature warehouse, 2-8℃ constant temperature refrigerated warehouse, -20℃ ultra-low temperature cold storage and independent dust-free packaging workshop. The warehouse is equipped with 24-hour intelligent fire monitoring, moisture-proof equipment, real-time temperature recording and backup refrigeration system to prevent raw material deterioration caused by temperature fluctuation and moisture. We implement partition storage, batch management, first-in-first-out inventory control and regular stocktaking to avoid batch mixing, expiration and quality degradation. The independent dust-free packaging workshop is specially built for export orders with professional sealing equipment and leak-proof packaging materials to adapt to long-distance cross-border transportation.
Standardized Production and Environmental Management
The factory implements closed-loop standardized daily management, including daily equipment cleaning, weekly workshop disinfection, monthly equipment maintenance and quarterly environmental monitoring. Waste liquid and solid chemical residues are disposed by qualified third-party hazardous waste treatment institutions, fully complying with national environmental protection standards with complete environmental compliance certificates. The industrial park is equipped with independent logistics loading and unloading docks and standardized passages, creating a clean, safe and standardized production environment.
Global Logistics and Cross-Border Export Advantages
As a self-operated import and export enterprise, Tanhong Import and Export Co., Ltd. holds complete import and export qualifications and a mature cross-border supply chain system, focusing on the global export of biochemical research raw materials and fine chemical intermediates.
