Whether "c-ul= csa +ul"?

Do you know what is "C-UL Certification"?  Whether C-UL= CSA + UL?

C-UL  Certification is a safety certification issued by UL,  it is evaluated with CSA Standards and for Canada marketing only!

If your products are to be  shipped  to the USA and Canada, you need to apply both UL and C-UL Certification!
