According to 49 CFR 180.603, the requirements for portable tanks used to transport hazardous materials are as follows:
* Authorized Packaging: Every portable tank must be an authorized packaging. To qualify, it must conform to the rules of this subchapter and the specific design specification it was built under.
* Approved Tank Types: The authorized portable tanks for use are types 51, 56, 57, 60, IM 101, IM 102, and UN portable tanks, provided they meet all applicable safety rules.
* Safe Containers Convention (CSC): If your portable tank also meets the definition of a "container" under 49 CFR 450.3(a)(3), it must follow the requirements in parts 450 through 453 to comply with Annex II of the CSC.
* Exemption Tanks (based on DOT 51): If you own a portable tank built and used under an exemption issued before August 31, 1996 (which matched DOT 51 specs except for fill and discharge outlet locations), you must examine the tank and its design against the October 1, 1996 outlet requirements:
* If it complies with all DOT 51 requirements, remove the stenciled exemption number.
* Durably mark the specification plate (or a plate right next to it) as "DOT 51-E*****" (replacing the asterisks with your exemption number).
* Keep a copy of the last active exemption on file at your principal place of business while the tank is in service and for one year after it is taken out of service.
