Freight Shipping Class Calculator
Calculate freight density in pounds per cubic foot (PCF) and determine the exact NMFC shipping class (Class 50 to 500) for Less-Than-Truckload (LTL) pallets.
Pallet Dimensions & Weight
Enter exterior pallet measurements in inches and total scale weight.
Understanding NMFC Freight Classes and Pallet Density
In Less-Than-Truckload (LTL) freight logistics across North America, carriers determine shipping rates based on the National Motor Freight Classification (NMFC) system. Freight classes range from Class 50 (the least expensive, extremely dense freight like steel ingots) to Class 500 (lightweight, highly fragile, low-density goods like ping pong balls or inflated balloons). Misclassifying freight results in costly carrier re-weigh and re-classification penalties.
Key Operational Features
Dimensional Cube Calculation
Computes total cubic volume in feet based on pallet length, width, and height in inches.
Density Engine (Pounds Per Cubic Foot)
Accurately divides total gross weight by cubic feet to yield precise PCF density.
Complete 18-Tier NMFC Class Lookup
Instantly maps calculated PCF to standardized NMFC classes ranging from Class 50 up to Class 500.
Multi-Pallet Aggregation
Add multiple identical pallets or combine mixed shipment weights into a unified average density bill.
Pallet Tare Weight Accounting
Accounts for standard wood pallet tare weight (approx. 40 lbs) ensuring carrier compliance.
Bill of Lading (BOL) Code Generator
Prepares clean documentation specs ready to paste onto carrier shipping documents.

Frequently Asked Questions
What is freight density (PCF)?
Freight density is the measurement of an item's compactness, expressed in pounds per cubic foot (PCF). It is calculated by dividing the total gross weight (in lbs) by the total volume (in cubic feet). Total cubic feet = (Length in inches x Width in inches x Height in inches) / 1,728.
How do freight classes affect shipping costs?
Lower freight classes (such as Class 50, 55, or 60) have the lowest shipping rates because they are dense, compact, and easy to handle. Higher freight classes (such as Class 300, 400, or 500) cost significantly more per pound because they take up substantial trailer space while contributing very little billable weight.
What happens if I put the wrong freight class on a Bill of Lading (BOL)?
Carriers inspect and measure cargo at regional distribution hubs. If they find the declared class does not match their scale and laser dimensioner readings, they issue a 'Weight and Inspection' (W&I) certificate along with a retroactive reclassification penalty fee (often $25 to $100+ plus the difference in freight rate).
Does pallet weight count in freight density calculations?
Yes. When calculating freight density for an LTL shipment, you must include the weight and exterior dimensions of the pallet or skid itself, not just the loose boxes on top.
