Question: Does DOT allow the use of MC306/DOT406 tank trailers for transporting crude oil, and where can I find the proper requirements for crude hauling? Thanks! Ken

Answer: Yes, you can haul crude oil in 306-406 tanks as long as the vapor pressure does not exceed the design pressure of the trailer. Most crude trailers being built today in the U.S. and Canada are 407 Spec. Basically the same as other petroleum tankers, the requirements for a tanker hauling crude is based on flash point and vapor pressure. Some crude can be hauled in non DOT tanks but is usually not done due to the versatility needed to haul all crude product, ranging from heavy crude all the way to condensate. This is the reason why DOT 407 is usually used for crude.

We purchased a 51' 4-axle Heil Trailer pull trailer from Semi Service in June of 2013. We have been very pleased with our increased payload, the durability of the trailer and the outstanding business relationship we have built with the team at Heil Trailer and Jim Amicone at Semi Service. With the success we have had with this product, I look forward to doing business again with Heil Trailer and Semi Service.Jon Shepherd, Services President, Northwest Petroleum
