Global e-commerce giant Amazon sought reliable suppliers of pet protective products, requiring them to possess large-scale delivery capabilities, international certifications, and flexible production capabilities. Hangzhou Zhenghong Pet Products Co., Ltd. secured access through its ISO9001 quality management system and BSCI certifications. Leveraging its 14,000-square-meter production facility and 400 pieces of equipment, it became a core supplier of pet protective products for Amazon’s own operations. Over the three years of this partnership, Zhenghong has supplied over 2 million pet raincoats and protective clothing to Amazon, maintaining a product return rate below the industry average and supporting Amazon’s expansion of its pet products business in North America, Europe, and Japan.
