Cubic Capacity Rule

Saia, Midwest Motor Express, and UPS Freight (TForce) adjust pallet height before calculating density.

Pallet height < 48"
Billed as if 48" tall (cubic-cap volume used)

Pallet height 48–96"
Billed as if 96" tall (cubic-cap volume used)

Pallet height > 96"
Actual height used — cubic rule likely already captured in class
