Request high-definition videos and close-up photos of the finishing, joints, and textures. For mass-produced items, ask for a Third-Party Inspection Report (e.g., SGS or Intertek). Pay close attention to colorfastness ratings (Grade 4 or higher) for dyed fabrics and the weight of the product, as heavier items often indicate higher material density and better structural integrity. On Made-in-China.com, look for Audited Suppliers to ensure the factory's production capacity and quality control systems have been verified.
