1. What is an LTL Freight Class Calculator?

Definition: This calculator determines the National Motor Freight Classification (NMFC) class based on the density of your shipment.

Purpose: It helps shippers estimate the freight class for Less-Than-Truckload (LTL) shipments, which affects shipping rates.

2. How Does the Calculator Work?

The calculator uses NMFC standards to assign a freight class based on density:

Where:

• \( Class \) — NMFC freight class (50-500)
• \( Density \) — Shipment density (pounds per cubic foot)

Explanation: Higher density shipments generally receive lower (better) freight classes, while lower density shipments receive higher classes.

3. Importance of Freight Class Calculation

Details: Correct freight class determination ensures accurate shipping rates and prevents reclassification fees. It's essential for cost-effective shipping.

4. Using the Calculator

Tips: Enter your shipment's density in pounds per cubic foot (lb/cu ft). The calculator will return the corresponding NMFC freight class.

5. Frequently Asked Questions (FAQ)

Q1: What is NMFC?
A: The National Motor Freight Classification system categorizes commodities for LTL shipping based on density, stowability, handling, and liability.

Q2: Why does freight class matter?
A: Freight class directly impacts shipping costs - lower classes (50-85) cost less to ship than higher classes (125-500).

Q3: What if my commodity has a specific NMFC item number?
A: Some commodities have predetermined classes regardless of density. Always check the NMFC guidelines for your specific item.

Q4: How do I calculate density?
A: Divide total weight (lbs) by total volume (cu ft). Volume = (Length × Width × Height in inches) ÷ 1728.

Q5: Are there other factors besides density?
A: Yes, stowability, handling, and liability can affect class, but density is the primary factor for most shipments.
