KEY: S = Withheld because estimate did not meet publication standards.

Z = Rounds to zero.

(1) UN numbers shown had the highest estimated weight without considering sampling variability. Since an “All other UN numbers” line is not shown, estimates do not add to total.

(2) Ton-miles estimates are based on estimated distances traveled along a modeled transportation network. See “Mileage Calculations” section for additional information.

NOTES: Value-of-shipments estimates have not been adjusted for price changes. Appendix B tables provide estimated measures of sampling variability. The Introduction and appendixes give information on confidentiality protection, sampling error, nonsampling error, sample design and definitions.
