The NACS Category Definitions and Numbering Guide can be used by the industry to establish performance benchmarks and a framework for retailers and manufacturers to have meaningful discussions regarding market performance comparisons.

Since 1998, the NACS Research Committee has worked closely with industry leaders and key stakeholders to provide a framework for data collection and benchmarking the industry’s category performance.  A product’s inclusion in one of the categories set forth has no meaning, express or implied, other than uniformity of treatment for benchmarking and comparative performance purposes.
