What Service Transport Company does

Service Transport Company (STC), founded in 1965 and headquartered in Houston, Texas, is a specialized bulk-liquid transportation carrier serving the chemical, petrochemical, petroleum, asphalt, and liquefied petroleum gas (LPG) industries across the United States and Canada. The company operates a fleet of more than 300 tractors (generally under three years old) and 425 trailers from 18 terminal locations, with asset configurations spanning stainless-steel insulated tanks, pressure vessels (including 15+ MC 331 LPG tanks), acid barrels, and multi-compartment units. STC also operates a four-bay tank wash rack and 16-bay maintenance facility at its Houston headquarters. Service offerings include liquid chemical bulk transport with in-transit heat and tank wash capabilities, dry bulk pneumatic transport, asphalt and emulsion delivery, and LPG transport.

The company's technology stack centers on third-party telematics rather than proprietary software: Peoplenet satellite systems interface with truck engines to monitor fuel mileage, performance, and faults, while TMW Systems / TMWSuite enterprise transportation software integrates those data feeds for fleet management, maintenance tracking, and customer invoicing. Safety architecture includes collision avoidance, stability control, lane departure warning, dash cams, critical event recorders, electronic logging devices, automatic transmissions, and disc brakes across the tractor fleet. The technology is best characterized as mature fleet-management infrastructure with no disclosed AI/ML components.

STC is a private subsidiary of the Trimac Family of Companies, a diversified bulk transportation group. The company operates as a contract carrier and 48-state non-radial common carrier, holds inter and intra-provincial authority in Ontario and Quebec, and is a Customs Self Assessment-approved customs bonded carrier into all of Canada. Revenue is generated through quote-based, contract-priced transportation services sold directly to enterprise shippers via a dedicated sales line (877-420-9490), with no public pricing or ARR disclosure. Customer segments are vertically segmented into Chemical/Petrochemical (primary), Asphalt/Construction (primary), LPG (primary), and Dry Bulk, supported by Responsible Care and EPA SmartWay credentials that position the company for risk-averse industrial RFPs.

Broad incumbents

• Daseke: Specialty flatbed and heavy-haul trucking roll-up with exposure to industrial and energy end markets. Comparable as a specialized asset-based carrier serving cyclical industrial customers, though focused on flatbed rather than liquid bulk.
• Schneider National: Large diversified truckload and intermodal carrier with a dedicated bulk and tank truck division. Comparable as a large-scale B2B carrier, though STC is more specialized in hazmat liquids while Schneider is a broader freight portfolio.
• Werner Enterprises: Large truckload carrier with dedicated and logistics businesses. Comparable as a similarly asset-heavy B2B carrier, though STC is more specialized in liquid bulk and Werner is more general freight focused.
• Hub Group: Asset-light intermodal and logistics provider with complementary dedicated and truckload services. Comparable as a diversified supply chain services company serving enterprise B2B customers in cyclical industrial end markets.
• J.B. Hunt Transport Services: Large multi-modal carrier with intermodal, dedicated, and final-mile services. Comparable in scale and B2B contract orientation, though broader and less specialized in liquid hazmat transportation than STC.
• Trimac Transportation (parent group): STC's parent conglomerate and Canada's largest bulk carrier. Provides group-level context for STC's service offering; operates across bulk trucking, transloading, and logistics with overlapping chemical and petroleum shipper relationships.

Regional players

• Superior Plus: Canadian-based propane distribution and specialty chemicals company with material LPG logistics needs. Comparable as a customer/adjacent player in the LPG value chain, particularly relevant to STC's cross-border LPG hauling capability.

Direct peers
