Mississippi Tank and Manufacturing Company

What Mississippi Tank and Manufacturing Company does

Mississippi Tank and Manufacturing Company (operating as Mississippi Tank Company) is a US-based custom fabricator of pressure vessels, bulk storage tanks, and transport equipment for the compressed gas and petrochemical industries, headquartered in Hattiesburg, Mississippi since its founding in 1945. The company designs and manufactures almost all products in-house, including compressed gas transport trailers, propane bobtail delivery units (1,200–8,500 USWG), and bulk storage tanks (6,585–120,000 USWG) for propane, chlorine, anhydrous ammonia, and natural gas liquids. Operations are supported by in-house heat treating furnaces rated to 1300°F, onsite post-weld heat treatment (PWHT) capability, ASME-certified welding, and DOT registration for MC-331 trailer design and repair. The company holds U and R ASME certificates and is a fully certified OEM plus authorized repair facility.

The business operates through four sites — Hattiesburg MS (HQ and Export Division), Vincennes IN (Indiana Division), Osceola IA, and Southaven MS (MTankCo Supply) — generating revenue primarily through one-time sales of custom-engineered capital equipment on quote-based, multi-year contract terms. Secondary revenue streams include parts distribution (MTankCo Supply, 50+ years), heat treating services, comprehensive repair and recertification services, and DOT/ASME testing and inspections, creating a full lifecycle service relationship with installed equipment. Customers are distributed across compressed gas distributors, petrochemical processors, LPG/NH3 operators, and chemical storage end users in the United States and Canada, with an emerging export channel.

Mississippi Tank operates as a privately held corporation and is consolidated under the TerraVest Industries family of compressed gas equipment companies (TerraVest LPG, TerraVest Tanks, Signature Truck Systems, Maxfield, Pro-Par, TerraVest Leasing), suggesting a coordinated corporate platform. The go-to-market combines direct enterprise field sales through regional offices, industry trade show participation (Western Propane Tradeshow, Eastern Energy Expo, and others), an emerging digital marketing presence (Google Ads, Facebook Ads), and a real-time online inventory storefront. Distribution is direct to enterprise buyers; no third-party resellers or international channel partners are disclosed.
