Why You Need a Freight Class Calculator

Why Freight Class Matters for Your Business
Freight class determines the cost of LTL and FTL shipments and helps prevent costly surprises. High-density, compact shipments usually have lower freight classes and cost less, while low-density, bulky shipments have higher classes. Knowing the correct freight class allows small businesses, virtual assistants, and e-commerce sellers to optimize packaging, reduce shipping expenses, and improve order fulfillment efficiency.
Tips to Optimize Your Shipment for Cost Savings
- Pack efficiently: Reduce empty space to increase density and lower freight class.
- Select the right pallet size: Avoid oversized pallets that increase volume unnecessarily.
- Use sturdy packaging: Prevents movement and handling issues that could affect class.
- Enter precise dimensions and weight: Accuracy prevents reclassification fees and ensures smooth processing on Amazon, Shopify, Etsy, Walmart, or with carriers.
