KEY:
– Represents an estimate equal to zero or less than 1 unit of measure.
S Estimate does not meet publication standards because of highly sampling variability or poor response quality.
CV Coefficient of variation of number

1 UN numbers were selected based on estimated tons without regard to sampling variability.

2 "Truck" as a single mode includes shipments that were made by only private truck, only for-hire truck, or a combination of private and for-hire truck.

3 Estimates for pipeline exclude shipments of crude petroleum.
