GB/T 38408-2019

This standard specifies a microscopy method for identifying the animal species origin of leather, such as distinguishing cowhide, sheepskin, or pigskin, by analyzing the unique histological features of the grain layer and fiber structure. It is applied in quality inspection, forensic analysis, and product authentication within the leather goods industry, including testing for footwear, garments, and upholstery. The method is used when visual or chemical identification is insufficient, ensuring accurate material declaration and preventing mislabeling in commercial and regulatory contexts.
