We'd love your feedback. If you spotted an error in the density chart, have a feature request, or have a question about how a freight class was estimated, get in touch.
We typically reply within a few business days. Please include your shipment dimensions and weight if you're asking about a specific calculation.
For classification questions that are binding on a shipment, your LTL carrier or the NMFTA is the authoritative source — we can only help with the density estimate.
