Core freight services
Hazmat Trucking
Full truckload (FTL) transportation of hazardous materials under DOT and FMCSA authority. We handle commodities across multiple hazmat classes including flammable liquids (Class 3), flammable gases (Class 2.1), corrosives (Class 8), and other regulated materials. Every shipment moves with proper placarding and documentation per 49 CFR.
Box-Truck Freight
Flexible box-truck transportation for general freight, partial loads, and non-hazmat shipments. Ideal for regional and long-haul lanes that don’t require a full tractor-trailer.
Nationwide Coverage
Freight service across all 48 contiguous states, dispatched from the Houston, TX metro. We coordinate pickup, routing, and drop-off to keep your supply chain on schedule.
Hazmat classes we transport
Our drivers and equipment are authorized to haul the following DOT hazmat classifications. Contact us to confirm lane availability and any commodity-specific requirements.
Class 2: Gases
Flammable gases (2.1), non-flammable/non-toxic gases (2.2), and toxic gases (2.3). Commodities include butane, petroleum products, and crude oil.
Class 3: Flammable Liquids
Fuels, solvents, and other flammable liquids transported under strict temperature and containment protocols.
Class 8: Corrosives
Acids, batteries, and corrosive substances requiring specialized handling and segregation.
All Additional Classes
Class 1 (Explosives), Class 4 (Flammable Solids), Class 5 (Oxidizers & Organic Peroxides), Class 6 (Toxic & Infectious Substances), Class 7 (Radioactive Materials), and Class 9 (Miscellaneous). We are authorized to haul all nine DOT hazmat classifications. Contact us to confirm specific commodity and lane requirements.
Equipment
Our fleet is maintained to DOT standards with current inspections, proper placarding materials, and safety equipment on every unit.
