Table 16c. Hazardous Material Shipment Characteristics for Export by Country of Destination: Percent of Total for 2007 and 2002
Estimates are based on data from the 2007 and 2002 Commodity Flow Surveys. Because of rounding, estimates may not be additive.
|Value (percent)||Tons (percent)||Value Standard Error of %||Tons Standard Error of %|
