NOTE: These composite estimates include out-of-scope shipments for sectors that are not included in Commodity Flow Survey (CFS) such as imports, logging, construction, retail, services, publishing, municipal solid waste, and household and business moves. They also include estimates of in-scope shipments for sectors that are covered in CFS but may have been underestimated due to small sample size, such as exports, intermodal, and petroleum products.
