How do I calculate the density of my shipment?

You can use the `calculate_shipping_density` tool. Simply provide the weight in pounds and the dimensions (length, width, and height) in inches.

What is NMFC freight class?

The National Motor Freight Classification (NMFC) system categorizes commodities based on density, ease of handling, and stability to determine shipping rates.

How does freight class affect my costs?

Higher freight classes (lower density) typically involve higher cost multipliers due to the increased space consumption in a trailer. You can use `evaluate_cost_impact` to see this effect.

This MCP server provides specialized tools for logistics professionals to calculate National Motor Freight Classification (NMFC) details. Use calculate_shipping_density to find the density in pounds per cubic foot (PCF) based on weight and dimensions. Then, use get_class_from_density to map that density to its specific NMFC class (ranging from Class 50 to 500). Finally, apply evaluate_cost_impact to estimate how the freight class affects your total shipping costs using a base rate per pound.
