(1) Commodity codes shown had the highest estimated weight without considering sampling variability. Since an “All other SCTG” 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.
(3) Estimates exclude shipments of crude petroleum (SCTG 16).
(4) Prior to the 2012 CFS, fuel alcohols such as ethanol were included in Commodity Code 08, although not specifically identified. Also, kerosene was included in Commodity Code 19. In the 2012 CFS, ethanol, fuel alcohols and kerosene moved to Commodity Code 17.
(5) Prior to the 2012 CFS, biodiesel, although not specifically identified, was included in Commodity Code 07. In the 2012 CFS, biodiesel moved to Commodity Code 18.
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.

Percentages represent the proportion of intra/interstate hazardous materials for two-digit commodity code shipments.
For purposes of this table, individual shipment data are classified as either completely “interstate” or completely “intrastate.” All shipments with the state of destination different from the state of origin are classified as “interstate.” All shipments having the state of origin the same as the state of destination are classified as “intrastate.”
