By Will Schweda, Senior Vice President of Sales, Odyssey Logistics Chemical freight rarely stays in one mode from origin to destination. A shipment may leave a plant by truck or rail, move through a port in an ISO tank, and finish by road, rail, or barge. Each transfer creates another point where equipment, documentation, carrier acceptance, and delivery timing have to line up. Those challenges apply to domestic U.S. freight, European distribution, and global chemical supply chains.
