To estimate your shipment, use the Corrugated Boxes Freight Class Calculator.
The Corrugated Boxes Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 65 to 175.
These are density-based estimates.

Corrugated Boxes shipment comparison
Corrugated box freight class can vary substantially with whether material is knocked down, bundled, baled, nested, or assembled. Flat sheets and compressed bundles often ship densely, while empty assembled boxes use far more trailer space per pound.
| Corrugated shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Knocked-down corrugated sheets and box blanks | Flat bundles banded to a pallet with top and bottom protection | Higher | Usually stackable | Flat material can produce efficient density when bundles remain square and fully supported. |
| Bundled folded cartons | Strapped bundles or uniform packs secured to a pallet | Medium | Usually stackable | Bundle height, compression, flute type, and pallet footprint can materially change density. |
| Assembled empty boxes and display cartons | Nested, wrapped, or loosely palletized assembled boxes | Lower | Often limited | Large cubic volume and crush sensitivity can restrict top loading and raise the density-based estimate. |
| Baled recovered corrugated cardboard | Compressed bales strapped or wired for handling | Higher | Varies | Bale consistency, moisture, wire condition, and safe forklift access are important planning factors. |
Corrugated Boxes shipping options
The right service depends on whether the material is flat, bundled, baled, or assembled; plus pallet count, footprint, stackability, moisture exposure, and crush sensitivity.
| Corrugated shipment | Common shipping option |
|---|---|
| Flat box blanks or bundled folded cartons on standard pallets | Standard LTL |
| Baled recovered corrugated cardboard | LTL or partial truckload with bale-handling review |
| Assembled boxes, displays, or low-density nested cartons | LTL with stackability and cube review |
| High-volume, oversized, or non-stackable corrugated loads | Partial truckload or dedicated service |
Wet, unstable, overhanging, loosely stacked, or non-stackable corrugated shipments may require carrier review, additional containment, or a different service type.

Freight classes shown on this page are density-based estimates for shipment planning. Actual classification may also depend on value, handling requirements, liability, stowability, dimensions, and other commodity-specific factors.
