Dear Customer, Thanks for your inquiry. There is no UL logo on the machine. We are currently doing ETLCE, Rohs, Reach, LFGB certification and UL test report. Thank you.

We currently have CE certification and UL test reports. All materials that come into contact with hot water are stainless steel, so you can use it with confidence. Thank you.

The plug is a standard 110V US plug.
