(1) NAICS codes shown had the highest estimated weight without considering sampling variability and are shown in descending order.
(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.

NAICS codes shown are those covered in the Commodity Flow Survey.
