I was wondering when this confusion would happen. The FMCSA wasn't thinking of Canada's CSA when they came up with that name. For those Americans that don't know, having a product stamped with CSA is the same as the UL (Underwriters Laboratories) certification.
The CSA in U.S. trucking is FMCSA’s Compliance, Safety, Accountability (CSA) program — formerly known as Comprehensive Safety Analysis (CSA 2010).
