Since China's accession to the WTO, the economic trend has been developing faster and faster, and the export quantity of footwear/leather products in China has also rapidly increased. However, trade frictions have also occurred frequently, and technical barriers have gradually become the main non-tariff trade barriers in trade. Europe and America often revise and update the regulations, standards, and testing methods of footwear products to monitor their compliance with their quality requirements
