Hello, I am interested in bringing some of my audio projects to market and am not sure what sort of certifcation is required to do so, is UL and CSA cert. required to sell electronics in North America? I see on many audio forums people sell tube amps and other projects they made and there is never any cert for those items, so when is it required? I have not found any definitive answers online so I hope maybe some of you folks might know.
Thanks for any input
