If you ship pallets\u2014even just occasionally\u2014the single factor that determines your rate is neither weight nor distance. It is freight class<\/strong>. And in 2026, that number is being calculated differently than it was two years ago.<\/p>\n

The National Motor Freight Traffic Association restructured the NMFC classification system based on density. The type of commodity no longer determines the class the way it used to. If your product is light and bulky, that change is costing you money right now, and most shippers have not recalculated a single SKU since the new system was implemented.<\/p>\n

Here's what has changed, how to calculate your actual class, and the packaging adjustments that cause a shipment to be downgraded to a lower tier.<\/p>\n

What Freight Class Actually Is<\/h2>\n

Freight class is a number between 50 and 500 assigned to every shipment transported as less-than-truckload. Class 50 is the least expensive to ship. Class 500 is the most expensive. The carrier applies its rate table to your freight class, weight, and route, then adds ancillary charges.<\/p>\n

Four factors have historically defined this class: density, stowability, handling, and liability. The modernization decisively shifted the emphasis of that formula toward density\u2014pounds per cubic foot\u2014for the majority of commodities.<\/p>\n

In practical terms: a pallet of ceramic tile and a pallet of foam inserts of the same weight are no longer even close in price, and the price gap is wider than it used to be.<\/p>\n

The density scale and the 13 tiers<\/h2>\n

The revised framework expanded from 11 density breaks to 13. Each tier maps a pounds-per-cubic-foot range directly to a class. More tiers mean finer granularity\u2014which has both advantages and disadvantages. Dense freight that used to be overclassified now receives a better rate. Light freight that used to fall comfortably into Class 100 now moves up to Class 125 or higher.<\/p>\n\n\n\n\n\n\n\n\n\n

Classes and bands are for reference only. The actual class applied is determined by your carrier\u2019s published tariff and your negotiated agreement.<\/em><\/p>\n

The number most shippers get wrong<\/h2>\n

Density is not the density of your product. It is the density of the shipping unit as submitted<\/strong> \u2014 pallet included, overhang included, and the empty space above your cartons included.<\/p>\n
