What Certifications Do You Need for Global Fan Markets?

A clean, modern commercial illustration of an electric floor fan, viewed from the front, centered before a globe marked "GLOBAL MARKET ACCESS." From the fan's hub, a network of arrows radiates outward to various certification marks, arranged in two columns. The left column shows "CE (EU)," "UL (North America)," "SASO (Middle East) [new logo]," and "SASO (Gulf) [older logo]." The right column shows "INMETRO (Brazil)," "DOE (US Energy)," "RoHS (EU Chemical)," and "REACH (EU Chemical)." The fan itself stands on a dark pedestal, set within a stylized outdoor customs checkpoint with blurred blue and red shipping containers, a gate with a green checkmark, and a truck. Above the globe, a prominent stamp reads "CUSTOMS PASSED APPROVED FOR GLOBAL TRADE." A main title bar across the top reads "GLOBAL FAN MARKET CERTIFICATIONS."
