DOT Regulations and DOT 406 Specification

A DOT 406 specification tank meets the federal requirements for the transport of Gasoline and AvGas over public roadways per Title 49 (Transportation) for transport in bulk containers. DOT406 tanks are also suitable for the transport of Diesel Fuel and Jet-A, BUT NOT REQUIRED. Please read below for more details.

Transport of Gasoline

A DOT 406 tank IS AUTHORIZED for the transport of Gasoline and AvGas (UN1203) on public roadways per FEDERAL transportation requirements.

The US transportation legislation that governs the transport of hazardous materials such as fuel is the Hazardous Materials Table found in Title 49 CFR §172.101. This table specifies that the transport of Gasoline (UN1203), including AvGas/100LL, and other fuels with flash points less than 38°C (100°F) in bulk containers be subject to 49 CFR §173.242 (Bulk packagings for certain medium hazard liquids and solids, including solids with dual hazards). The flash-point, the temperature at which a fuel can vaporize to form an ignitable mixture, for gasoline is less than -40°C (-40°F). 49 CFR §173.242 cites DOT 406 tanks as suitable for the transport of such materials. The details of the DOT 406 specification can be found in 49 CFR §178 sub-parts 345 and 346.

The TransCube is authorized for the transport of gasoline as a UN 31A Group Y IBC.  See below.

Transport of No. 2 Diesel Fuel and Jet-A

A DOT 406 tank IS NOT REQUIRED but IS AUTHORIZED for the transport of Diesel Fuel (UN1202/NA1993) or Jet-A/Jet Fuel (UN1863) on public roadways per FEDERAL transportation requirements.

DOT 406 tank is also suitable for the transport of No. 2 Diesel Fuel (UN1202/NA1993) and Jet-A/Jet Fuel (UN1863), BUT IS NOT REQUIRED per Special Provision B1 found in 49 CFR 172.102, p. 325 noted in the Hazardous Materials Table found in 49 CFR §172.101. Special Provision B1 specifies that materials with flash-points above 38°C (100°F) and lower than 93°C (200°F) are subject to 49 CFR §173.241 (Bulk packagings for certain low hazard liquid and solid materials). 49 CFR §173.241 specifies that non-DOT specification cargo tank motor vehicles are suitable for the transport of such fuels. No. 2 Diesel Fuel (UN1202/NA1993) and Jet-A/Jet Fuel (UN1863) have a flash-point greater than 58°C (125°F).

The TransCube is authorized for the transport of PG II and III liquids such as diesel and Jet-A as a UN 31A Group Y IBC.  See below.
