Scope boundary
Contact Page Usage Limitations
This site provides density-based planning estimates — that's the full scope of what it does. If you're trying to book a shipment, get a freight quote, look up an NMFC item number, or dispute a carrier invoice, this isn't the right contact form to use. We're not a carrier, broker, or classification service, and we can't help with active shipment issues. If the tool gave you a result that seems off, or something on the site looks wrong or outdated, that's exactly the kind of thing we do want to hear about.The contact address is not a carrier, broker, shipping desk, NMFC classification service, or freight quote service.
Final shipment decisions
Confirm final freight class, NMFC item classification, shipment details, pricing, billing requirements, and carrier rules with your carrier, broker, or NMFC source before booking or billing.
