The National Motor Freight Classification (NMFC) system categorizes LTL freight into 18 classes (Class 50 to Class 400) based on density (weight per cubic foot), stowability, handling, and liability. Higher classes = lower density = higher freight rates.
| Density (PCF) | Freight Class | Typical Rate |
|---|---|---|
| < 1 PCF | Class 400 | Highest Rate |
| 1 – < 2 PCF | Class 300 | Highest Rate |
| 2 – < 4 PCF | Class 250 | High Rate |
| 4 – < 6 PCF | Class 175 | High Rate |
| 6 – < 8 PCF | Class 125 | Medium Rate |
| 8 – < 10 PCF | Class 100 | Medium Rate |
| 10 – < 12 PCF | Class 92.5 | Medium Rate |
| 12 – < 15 PCF | Class 85 | Low Rate |
| 15 – < 22.5 PCF | Class 70 | Low Rate |
| 22.5 – < 30 PCF | Class 65 | Low Rate |
| 30 – < 35 PCF | Class 60 | Low Rate |
| 35 – < 50 PCF | Class 55 | Lowest Rate |
| ≥ 50 PCF | Class 50 | Lowest Rate |

What is LTL Freight Class?
Less-Than-Truckload (LTL) freight class is a standardized system established by the NMFC (National Motor Freight Classification) to categorize shipments for pricing. Every LTL shipment is assigned a class from Class 50 (densest, cheapest) to Class 400(lightest, most expensive). The primary factor for most commodities is density.
How to Calculate Freight Density
Density (PCF) = Total Weight (lbs) ÷ Total Volume (cubic feet). Volume is calculated as (Length × Width × Height) ÷ 1,728. A higher density means a lower, cheaper freight class. Use this free 2026 LTL freight class calculator to instantly determine your NMFC class.
Common NMFC Codes for Produce & Groceries
If you are shipping fresh produce, use these specific NMFC codes alongside our density calculator:
| Commodity | NMFC Code | Notes |
|---|---|---|
| Potatoes & Onions | 49670 | Often Freight Class 55 or 65 depending on packaging/density |
| Apples | 42540 | Varies based on carton sizes and pallet efficiency |
| Bananas | 77600 | Requires strict temperature control limits (Reefer LTL) |
