LTL freight tools

NMFC freight class calculator

Look up the freight class for a US LTL shipment from its dimensions, weight, and handling flags. Aligned to the 13-tier density ladder that took effect on 2025-07-19, with the legacy ladder available for retrospective quotes.

Weight & pieces
Handling flags

Active flags bump the freight class up one ladder step (LTL convention; carrier may apply more).

How the 2025 NMFC density scale works

  1. 1

    Measure cubic feet

    Length × width × height (inches) ÷ 1,728. Convert from cm with the unit toggle.

  2. 2

    Compute density (PCF)

    Total weight in pounds ÷ cubic feet. That's pounds per cubic foot — the only input that drives class on the 2025 ladder.

  3. 3

    Map to class

    The 13-rung ladder maps PCF ranges to NMFC class labels. Handling flags bump one step up (LTL convention).

FAQ

Is this an actual NMFC quote?
No. The class returned is a density-only estimate. NMFC item-specific exceptions, hazmat tariffs, and carrier-specific accessorials can override it. Use this to set expectations and verify a quote, not to replace one.
What changed on 2025-07-19?
The NMFC simplified to a 13-tier density-only scale for non-exception commodities, replacing the older 11-tier ladder. Switch the ruleset toggle to compare a shipment under both.
Why do handling flags bump only one class?
Most LTL carriers apply a single class bump for the worst-fitting handling exception (fragile, hazmat, non-stackable, high-value). Stacking bumps multiplicatively isn't standard — additional flags drive accessorials and surcharges instead.
Do you publish NMFC item codes?
No. NMFC item codes are commercially licensed by NMFTA. This tool uses only the public density scale facts. Look up your item code via your carrier or NMFTA's ClassIT.

Disclaimer

Results are orientative and do not constitute a binding carrier quote, tax advice, or legal advice. Density-based class is the starting point; item-specific NMFC entries, hazmat regulations, dimensional exceptions, and carrier accessorials can change the actual rated class.
