To ensure market access and user safety, products must adhere to regional certifications. For the US market, UL or ETL listing is essential, along with FCC Part 15 compliance for electromagnetic interference. For the EU, look for CE marking (LVD and EMC directives) and RoHS (Restriction of Hazardous Substances) to ensure the plastic and electronic components are free from toxic heavy metals. For outdoor or industrial use, verify the IP Rating (e.g., IP65 or IP67) to ensure protection against dust and water ingress.
