About Chemical & Acid Tank Semitrailers
From highly corrosive liquids to mild acids, chemical and acid tank semitrailers are built to safely transport hazardous liquids in bulk and are designed to meet stringent Transport Canada regulations and, in most cases, those of the U.S. Department of Transportation. Semitrailers for sale in this category are generally equipped with stainless steel tanks, in some cases with an inner liner to prevent corrosion when transporting highly corrosive liquids like hydrochloric acid.

STE DOT 407 Chemical Tank Semitrailer
Regulation & Design
Tanks on chemical and acid semitrailers are governed in the U.S. by DOT 407 and DOT 412 requirements, and in Canada by Transport Canada’s Transportation of Dangerous Goods program. DOT 407-compliant tank semitrailers transport non-corrosive liquids, and DOT 412-complaint tank semitrailers are reinforced with tank liners and other equipment to transport the most corrosive and acidic liquids. For example, tank semitrailers with fiberglass reinforced plastic liners provide DOT 412 compliance for substances like sulfuric acid, while rubber-lined tank semitrailers meet DOT 412 requirements for bleach or hydrochloric acid.
In addition to tank composition differences, DOT requirements for chemical and acid semitrailers typically specify exact loading temperatures, maximum allowable working pressure (MAWP), and other shell and fitting constructions to ensure safe filling, transport, and unloading.
Capacities & Options
Chemical and acid semitrailers often have tank capacities ranging from 11,300 to 38,000 litres (3,000 to 10,000 gallons). As with other types of semitrailers, greater capacity requires more axles to safely transport a load; tandem-axle configurations are the most common in this category, though 3- and 4-axle configurations are available. Tanks may have a single interior compartment or as many as five. Models with multiple tank compartments allow haulers to simultaneously transport different chemicals and acids if other required equipment (such as a vapor recovery system) is present. Operators transporting more viscous fluids, such as glue, glycerin, or synthetic resin, might require a semitrailer with a deep drop for easier unloading.
