body: Theoretical: I wish to import and sell wall chargers in the USA. 
  
  
  I realize it is a good idea to get a safety certificate that signifies my product meets national safety standards to avoid being sued.
  
  
  However, my question is whether it is legal to sell them without a safety certificate (ETL, UL, etc).
