Fleet and Operational Capacity

Polmax operates an asset-based model, owning and maintaining its transportation fleet rather than relying on contracted carriers. According to FMCSA records, the company’s operational capacity includes:

Fleet Composition:

• Trucks: 102-112 power units
• Drivers: 102 employed drivers
• Annual Mileage: 9,992,501 miles (2024 data)

The company purchases equipment new and maintains vehicles at an on-site repair facility, prioritizing fleet reliability and reducing roadside breakdowns. This asset-based approach provides direct control over equipment quality, driver standards, and service delivery timelines.

Service Portfolio

Polmax LLC provides multiple freight transportation services through its Experior Transport brand:

• LTL Services: Direct shipment handling where freight loads in delivery order and remains untouched throughout transit. This approach reduces handling-related damage and shortens transit times compared to traditional LTL carriers that consolidate and redistribute freight at multiple terminals.
• Volume LTL: Specialized service for shipments larger than standard LTL freight but smaller than full truckload. Direct delivery model applies, avoiding mid-route handling.
• Refrigerated LTL: Temperature-controlled transportation for frozen and refrigerated freight, addressing a service gap many LTL carriers cannot accommodate.
• Truckload Services: Full truckload transportation across all 48 contiguous states, including dedicated route services for consistent lanes.
• Pharmaceutical Transportation: Specialized service for biotechnology and pharmaceutical products requiring strict temperature control, GPS monitoring, thermal mapping, and trained drivers following standard operating procedures for cold chain integrity.
• Expedited Services: Time-critical shipments requiring faster-than-standard delivery schedules.
• Trade Show Transportation: Specialized handling for exhibit materials, including full pad wrap services, advanced receiving coordination, and direct-to-showroom-floor delivery.

Geographic Coverage and Network

The company operates from its Alsip, Illinois headquarters, strategically positioned approximately 20 minutes south of Chicago. This location provides access to major interstate corridors serving the Midwest and the Great Lakes regions.

Experior Transport maintains coast-to-coast and border-to-border network coverage through its asset-based fleet and freight brokerage operations. When company-owned equipment doesn’t match customer constraints, the company utilizes vetted carrier contracts to fulfill transportation needs through its brokerage division.

The company offers Load to Ride opportunities, where return trips to the Illinois home base create cost-saving freight opportunities for shippers whose routes align with driver repositioning needs.

Insurance and Liability Coverage

Polmax maintains required commercial transportation insurance through Arch Insurance Company with $1 million BIPD (Bodily Injury and Property Damage) coverage, meeting FMCSA minimum insurance requirements for interstate carriers.

For pharmaceutical and high-value shipments, the company implements additional security protocols, including GPS tracking, trailer-mounted cameras for continuous inventory monitoring, pre-planned routes avoiding high-risk areas, and 24/7 dispatch availability during transit.

Technology and Operational Systems

Experior Transport implements EDI (Electronic Data Interchange) and API technology for real-time freight matching with available capacity, ensuring continuous shipment movement. The system instantly connects customer freight requirements with truck availability across the network.

Fleet management incorporates GPS units embedded in tractors and trailers, enabling route tracking, driver communication, and customer shipment visibility. The company utilizes route optimization software to improve efficiency and reduce deadhead miles.

Market Position and Competitive Context

The freight trucking industry contains over 570,000 companies in the United States, creating an extremely fragmented and competitive landscape. Polmax LLC operates as a mid-sized regional carrier, competing against both large national carriers and smaller local operators.

Asset-based carriers like Polmax own their equipment and employ their drivers, contrasting with asset-light brokerages that coordinate shipments through third-party carriers. Asset-based operations provide greater control over service quality, delivery reliability, and customer relationships but require significant capital investment in fleet acquisition and maintenance.

Industry valuation multiples for private trucking companies currently range from 5-8x EBITDA for asset-based carriers, though actual valuations depend heavily on fleet condition, customer contracts, geographic reach, operational efficiency, and profitability margins.

Regulatory Compliance and Safety Performance

The company’s Satisfactory FMCSA safety rating, maintained since 2010, indicates sustained compliance with federal transportation regulations. This rating requires meeting standards across multiple categories:

• Driver qualification and training
• Hours of service compliance
• Vehicle maintenance and inspection
• Controlled substances and alcohol testing
• Accident prevention and safety management
• Hazardous materials handling (when applicable)

Carriers falling below compliance standards receive Conditional or Unsatisfactory ratings, potentially limiting their ability to operate or secure customer contracts. Polmax’s long-standing Satisfactory status demonstrates consistent regulatory adherence.

Employment and Company Culture

Polmax LLC employs approximately 102 drivers and maintains additional administrative, dispatch, and maintenance staff at its Alsip headquarters. The company describes itself as a family-owned business emphasizing quality standards in personnel, equipment, and operating principles.

Driver recruitment follows stringent hiring requirements, with the company selecting candidates meeting higher-than-average qualification standards. Drivers receive specialized training for pharmaceutical and temperature-controlled freight, ensuring proper handling of sensitive cargo.

The company operates a driver lounge with amenities including comfortable beds and showers, catering services, and professional facilities designed to support driver retention in a competitive labor market.

Industry Context and Transportation Trends

The trucking industry faces ongoing challenges, including driver shortages, fuel price volatility, capacity fluctuations, and increasing regulatory requirements. According to industry data, trucking profit margins typically range between 4-8%, with top-performing operators achieving higher margins through operational efficiency and service specialization.

Asset-based carriers must balance fleet modernization costs (replacing aging equipment) with operational profitability. Fleet replacement represents significant capital expenditure that EBITDA calculations alone don’t capture, making cash flow analysis critical for understanding the company’s financial health.

Specialized services like pharmaceutical transportation, refrigerated freight, and dedicated routing typically command higher rates than standard dry van freight, allowing carriers to improve margins through service differentiation.

Summary

Polmax LLC operates as a mid-sized, family-owned asset-based carrier serving the United States through its Experior Transport brand. With USDOT 758399 and MC 342107, the company maintains 102+ trucks, employs 102 drivers, and logs nearly 10 million miles annually.

The company’s service portfolio spans LTL, truckload, refrigerated, and pharmaceutical transportation, with specialized capabilities in temperature-controlled freight and trade show logistics. Its Satisfactory FMCSA safety rating, maintained since 2010, reflects sustained regulatory compliance.

Operating from Alsip, Illinois, Polmax combines asset-based fleet control with freight brokerage capabilities, providing direct service through company equipment and expanded capacity through vetted carrier partnerships. The company’s focus on quality equipment, driver selection, and operational standards positions it within the competitive mid-sized carrier segment of the fragmented trucking industry.
