National Tank Services

What National Tank Services does

National Tank Services (NTS) is a North American provider of tank cleaning, truck and trailer maintenance, inspection, testing, and certification services for the bulk transportation industry, operating as a subsidiary brand within the Trimac Transportation corporate family (which employs more than 4,000 people across over 140 branches and traces its origins to 1945 in Calgary, Alberta). NTS operates more than 40 service centers across Canada and the United States, with certain locations (e.g., Edmonton, Kamloops, Texas) running 24/7 or after-hours emergency service. The company serves three primary customer segments: commercial fleet operators requiring ongoing maintenance, tank cleaning, and regulatory compliance; independent owner-operators and small trucking companies needing cost-effective certification and maintenance; and the internal Trimac fleet, which provides a captive demand backbone.

The company's technology and capabilities center on industrial cleaning methods (caustic wash, detergent wash, boosted caustic, acrylate and MDI wash, latex stripper, polymer cleaning, steam cleaning, passivation, and food-grade and kosher-certified cleaning at select locations) and regulatory certification backed by ASME 'U' Stamp and National Board 'R' Stamp credentials, HM-183 inspection capability, and MC330/331/338 (including cryogenic) testing. Maintenance offerings span preventive maintenance programs, mechanical repairs (brakes, suspension, transmission, clutches, electrical, air conditioning), wastewater management, and waste disposal to meet environmental compliance. A new line in ISO container cleaning, lifting, storage, and intermodal tank services extends the addressable market beyond over-the-road tank trailers.

The business model is straightforward industrial services revenue: per-transaction fees for tank washes, maintenance tickets, inspections, and certifications, with quote-based pricing determined by tank type, cargo, and regulatory requirements. NTS has executed 105,500+ tank washes and 82,450+ repair/PM services across 750+ customers. Sales operate direct-to-customer via phone and the service request form, supported by a corporate website at trimac.com with a dedicated NTS section and location finder. NTS holds NTTC's Safest Tank Truck Carrier recognition (2025) and TFE 5 Years of Distinction (2025), reinforcing a safety-led brand premium in a regulated, hazmat-adjacent category.

Broad incumbents

• Heritage-Crystal Clean: Heritage-Crystal Clean offers parts cleaning, industrial waste management, and container services across North America. Its container and industrial cleaning segments overlap with NTS's tank wash and depot services, though it is more focused on smaller-format parts washers and lubricants.
• Clean Harbors: Clean Harbors is the largest North American provider of environmental and industrial services, including tank cleaning, waste disposal, and field services. It overlaps with NTS on chemical-tank cleaning and hazardous-waste handling but operates a far broader portfolio and serves much larger enterprise customers across multiple verticals.

Direct peers

• ACT Environmental Services: ACT Environmental Services provides industrial cleaning, tank cleaning, and waste management services across multiple U.S. sites. It competes with NTS for chemical and industrial tank cleaning work and has comparable multi-location service-center economics.
• PSC Industrial Services: PSC provides industrial cleaning, tank services, and specialty mechanical services to refineries, chemical plants, and bulk transporters. It is the most direct head-to-head competitor in terms of industrial tank cleaning and on-site specialty cleaning methods comparable to NTS's acrylate and caustic wash offerings.
• Clean Earth: Clean Earth provides specialty waste handling and industrial cleaning services including tank and container cleaning for chemical and industrial customers. It competes with NTS for chemical and hazmat-related tank cleaning work, particularly in the eastern and southern U.S.
• Triumvirate Environmental: Triumvirate Environmental is an industrial services company offering tank cleaning, waste management, and emergency response services to chemical, pharmaceutical, and manufacturing customers. Its tank-cleaning and specialty cleaning services are directly comparable to NTS's chemical tank wash offerings.

Regional players

• Quality Carriers: Quality Carriers is one of the largest U.S. bulk chemical haulers, with captive maintenance and tank cleaning infrastructure serving its own fleet. While it is primarily a carrier rather than a service provider, its in-house tank wash operations represent the vertical-integration alternative that competes with NTS for third-party tank-cleaning business.

Others

• Trimac Transportation: Trimac Transportation is the parent company and primary related-party customer for NTS. While not a direct competitor, Trimac's bulk chemical hauling operations are the largest single demand source for NTS and define the captive customer base.
