DOT 412 Trailers: Description And Key Properties

DOT 412 trailers have a capacity that ranges from 4,000 to 5,500 gallons and a typical GCWR of 80,000 pounds. The maximum allowable working pressure (MAWP) is 35 PSI and the maximum loading temperature is typically 150 degrees fahrenheit. DOT 412 trailer models also come with single or multiple compartments, and may be lined and / or insulated in accordance with product requirements and customer specifications.

DOT 412 trailers are manufactured from specialty stainless steel to improve corrosion resistance and often have visible rings around the tank barrel. The inside of the tank may be equipped with rubber or fiberglass reinforced plastic (FRP) tank liners to accommodate specific products. For example, Wabash manufactures a line of corrosive tanks that has a fiber-reinforced plastic unit which enables it to transport sulfuric acid concentrations up to 98 percent.

How Does A DOT 412 Trailer Compare To Other Trailer Types

The three (3) most common U.S. Department of Transportation (DOT) chemical tanker types are: the DOT 406, the DOT 407, and the DOT 412 trailer models. These units are important to the chemical transportation industry with each type of trailer transporting a specific class of chemicals and meeting strict DOT standards.

  • DOT 406 trailers are commonly used for the transportation of petroleum products, food products, and water. The DOT 406 trailer is generally constructed from aluminum and is often compartmentalized to accommodate formula variations of the same product.
  • DOT 407 trailers are most often constructed of stainless steel and are designed to transport non-corrosive chemicals such as combustible materials and mild acids, including food grade products.
  • DOT 412 trailers are designed to handle corrosive materials and heavier liquids. Thus, the DOT requirements are stricter in order to minimize safety and environmental risks during the transport of hazardous liquids.
