Steffes Expands Manufacturing Capabilities as DOT Certified Cargo Tank Facility

Steffes was recently registered by the Department of Transportation as a certified cargo tank facility. This certification positions Steffes as the first company in North Dakota authorized to manufacture, assemble, repair, and inspect cargo tanks in-house. In addition to our existing ASME Code ‘U’ Stamp, ‘UM’ Stamp and ‘R’ Stamp, we are also certified to repair both ASME and Non-ASME cargo tanks. 

As a contract manufacturing partner, Steffes will begin using this certification immediately to manufacture stainless steel emulsion tanks. We remain committed to manufacturing to the highest quality standards in every industry we serve and maintain a variety of quality certifications including a UL Certification, ISO 9001:2015, API Q1-9th Edition, ASME, and OSHA Safety and Health Achievement Recognition Program Certification in addition to DOT 407/412.
