Since 2013, DCL’s common-series electric actuators from Huayi Technology have been CSA certified, fully complying with both U.S. (UL) and Canadian (CSA) standards. Our explosion-proof models are currently undergoing CSA testing, with certification expected in Q3–Q4 of 2020. Furthermore, all DCL products are CE marked and RoHS 3.0 compliant, with all testing conducted by SGS to ensure international environmental and safety alignment.

Quality control is maintained through a rigorous oversight framework: any modification to components or suppliers must be documented and approved by the CSA. Additionally, CSA experts from both the Canadian headquarters and China offices perform quarterly factory audits. This strict adherence to UL and CSA protocols ensures exceptional quality stability and has earned DCL broad recognition across the North American market.
