KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality; — = data cell equal to zero or less than 1 unit of measure; CFS=Commodity Flow Survey.,,,,,,
"NOTES:  Truck as a single mode includes shipments that were made by only private truck, only for-hire truck, or a combination or private and for-hire truck.  Pipeline includes shipments of crude petroleum.  Other multiple modes include combination of truck and water, rail and water, and other combinations.  The composite estimates include Commodity Flow Survey (CFS) data  and out-of-scope shipments for sectors that are not included in the CFS such as imports, logging, construction, retail, services, publishing, municipal solid waste, and household and business moves.  The composite estimates 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.
