Duncan and Son Lines

What Duncan and Son Lines does

Duncan and Son Lines, Inc. is a privately held U.S. transportation company providing intermodal transportation services and international cargo trucking. Founded in 1943 and headquartered in Buckeye, Arizona, the firm has operated continuously for more than 80 years and currently maintains a headcount of 101-250 employees, placing it in the small-to-mid-cap range for U.S. trucking and intermodal carriers. Its service positioning spans both intermodal (rail-truck combined) transport and cross-border/international cargo trucking, suggesting a dual exposure to domestic lane economics and North American cross-border freight flows.

The business model appears to be a traditional asset-based or asset-light carrier model typical of the U.S. intermodal and international trucking segment, generating revenue per load moved across its operating lanes. However, deeper operational detail — fleet composition, lane network, drayage versus long-haul mix, customer mix, pricing structure, and technology stack — is not extractable from the input data. The corporate website at duncanandson.com currently renders only a verification/loading page ("One moment, please..."), with no accessible product, customer, leadership, or financial content available through the sources reviewed.

Because of this public-facing information gap, the precise scope of operations, customer segments served, contract structure, and growth posture cannot be confirmed from the input data. What is verifiable is the firm's long operating history, private ownership status, U.S. domicile in Buckeye, Arizona, and positioning as a multi-generational intermodal and international trucking operator.
