Zijintang's postpartum care products are manufactured in a food factory certified with both the ISO 22000 Food Safety Management System and HACCP. From the selection and cleaning of ingredients and herbs, to concentration and extraction, filling, packaging, high-temperature high-pressure sterilization, shelf-life testing, and final shipment—each step undergoes rigorous hazard analysis and strict control measures to ensure multilayered food safety assurance.

In addition to product and process controls, Zijintang commissions impartial third-party inspection agencies to conduct comprehensive testing based on the characteristics of each product. Tests include checks for 310 pesticide residues, heavy metal residues, sulfur dioxide residues, and more. All products have passed these inspections, providing you with added confidence in their safety.

To ensure product safety and stability, we conduct normal temperature storage tests, 37℃ storage tests, and 55℃ accelerated aging tests. We continuously monitor and verify product quality throughout the sales period and utilize a traceability system to track product distribution.

Beyond strict production and quality control, Zijintang has further strengthened its commitment to quality by purchasing NT$50 million in product liability insurance from Nan Shan General Insurance. This highest-level coverage ensures the protection of every consumer’s rights and interests.
