In 2001 the CBSA launched Customs Self Assessment (CSA), a comprehensive program based on risk management and partnership with approved importers and carriers. Canada further allows CSA approved importers to use their own business systems to declare shipments.

Under CSA, the import process of shipping to Canada is optimized from an accounting and payment perspective, and Canadian customs clearance is streamlined for those utilizing approved carriers and drivers. Substantial cost savings may result from the efficiencies gained under this model.

In order to participate in this program, U.S. and organizations must undergo a rigorous, multi-phased application process that includes a risk assessment, an audit of books and records, and an evaluation of their internal business systems. All CSA transactions must be completed electronically so robust accounting and technology capabilities are required.
