How to Lower Your Freight Class and Save Money

Density is the Shippers' Leverage

For supply chain directors and packaging engineers, the freight class isn't a fixed rule—it's a variable you can control. In the world of LTL, Density (PCF) is the primary driver of cost. If your product has a low density, you land in a high freight class (e.g. Class 250). If you can increase that density, even by a small margin, you can drop your class to 150 or 125, instantly saving 30-50% on every shipment. The secret to this leverage lies in the elimination of "dead air" within your packaging.

Packaging Optimization Strategy

• Eliminate Over-Boxing: Using a "one size fits all" box for different products is a pricing disaster. Custom-fit cartons ensure your density is always maximized.
• The Stackability multiplier: Non-stackable freight is often classed higher. Flatten your pallet tops and ensure they can support weight to avoid "Capacity Load" penalties.
• Remove the Overhang: Product overhanging a pallet by just 2 inches increases your "theoretical" footprint by nearly 10%, tanking your density score.
• Vacuum-Sealing & Compression: For textiles or foam-based products, mechanical compression can drop your freight class from 300 to 70 in a single step.

Why Your CFO Loves Density

Freight costs are often the third-largest expense for a product-based company. By focusing on packaging engineering to lower freight class, you aren't just "reducing costs"—you are fundamentally improving your gross margin. A 20% reduction in freight class can be the difference between a profitable product line and a loss-leader.
