Terms & Conditions

Last updated: September 2, 2026

These Terms & Conditions ("Terms") govern your use of onlinefreightclasscalculator.com and its tools (the "Site"). By using the Site, you agree to these Terms. If you do not agree, please do not use the Site.

Estimates only — not a classification authority

The freight class calculator, density chart, commodity lookup, dimensional weight calculator, and reclass cost estimator are provided for general informational purposes only. They produce estimates based on standard, density-based NMFC freight class tables and the information you enter.

We are not affiliated with, endorsed by, or acting on behalf of the National Motor Freight Traffic Association (NMFTA), which is the sole official publisher of the National Motor Freight Classification (NMFC). Actual freight class can depend on factors beyond density alone — including commodity, packaging, stowability, handling, and liability — and is ultimately determined by the carrier handling your shipment or by referencing the official NMFC. Always confirm class and freight charges with your carrier or broker before booking or shipping.

No liability for shipping decisions

To the fullest extent permitted by law, Freight Class Calculator and its operators are not liable for any loss, cost, reweigh or reclass fee, delay, or other damage arising from reliance on results produced by the Site. You are solely responsible for verifying classification and shipping information before acting on it.

Acceptable use

You agree not to:

  • Use the Site for any unlawful purpose or in violation of these Terms
  • Attempt to disrupt, overload, or interfere with the Site's operation or security
  • Scrape, reverse engineer, or republish the Site's content or tools without permission
  • Misrepresent results from the Site as an official NMFC classification

Intellectual property

The Site's design, text, and tools are owned by Freight Class Calculator unless otherwise noted, and may not be copied or redistributed without permission.

"As is" — no warranty

The Site and its tools are provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, reliability, or fitness for a particular purpose.
