Estimates are based on data from the 2007 Commodity Flow Survey. Because of rounding, estimates may not be additive.

KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality. - = Zero or Less than half the unit shown; thus, it has been rounded to zero.
1 Standard Classification of Transported
2 Coefficient of Variation.
3 Estimates exclude shipments of crude petroleum (SCTG 16).
NOTES: Value-of-shipment estimates have not been adjusted for price changes. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables.
