# FreightCal - LTL Freight Class & Logistics Intelligence Suite

> FreightCal (https://ltldensitycalc.com) is a free, professional logistics intelligence and freight calculation platform built for North American shippers, 3PL freight brokers, warehouse operations managers, and carriers. All calculation engines run client-side with 100% zero data retention.

## Core Capabilities & Calculations

- **LTL Freight Class Calculator:** Computes pounds per cubic foot (PCF) density and matches it against the official 2026 NMFTA 11-tier density matrix (Class 50 to Class 500).
  - Formula: Volume (cu ft) = (Length × Width × Height in inches) / 1,728
  - Density (PCF) = Total Weight (lbs) / Total Volume (cu ft)

- **NMFC Code & Commodity Directory:** Comprehensive searchable database of 200+ freight commodities across 15 industrial sectors, listing specific NMFC item numbers, sub-items, and density requirements.

- **Industrial & Shipping Material Density Database:** Physical density (PCF, g/cm³, kg/m³), recommended NMFC classification, pallet weight limits, and 53ft trailer utilization for 34 industrial materials (Metals, Building Materials, Timber, Plastics, Bulk Liquids).

- **Pallet Loading (Ti-Hi) Calculator:** Optimizes carton stacking patterns per tier (Ti) and number of layers (Hi) on standard 48"×40" GMA pallets, enforcing 2,500 lbs structural safety thresholds and overhang rules.
