For the European market, the machine must have a CE Certification to ensure it meets safety, health, and environmental protection requirements. For the North American market, look for UL or ETL listed components, especially for the electrical and heating systems. Since the machine handles consumable products, the contact parts (needles, tubes, tanks) must be made of food-grade Stainless Steel 316L and medical-grade silicone to prevent contamination and comply with GMP (Good Manufacturing Practice) standards.
