(1) Shipments that are temperature controlled are transported in a vehicle or container that regulates or maintains the temperature when en route to its destination.
(2) NAICS codes shown are those covered in the Commodity Flow Survey.
(3) Ton-miles estimates are based on estimated distances traveled along a modeled transportation network. See “Mileage Calculations” section for additional information.
(4) For tabulation and publication purposes, NAICS 484 is grouped with NAICS 4931.
