Products must comply with CE, RoHS, and FDA regulations if being sold in European or American markets. Key technical benchmarks include vacuum insulation technology for non-electric flasks and high-precision NTC temperature sensors for digital cases to ensure accuracy within ±0.5°C. For battery-operated units, look for UN38.3 certification, which is mandatory for air transport safety. Additionally, the outer shell should be made of impact-resistant EVA or ABS plastic to protect fragile insulin vials or pens from physical damage.
