Cubic capacity is specifically a North American LTL trucking term. It imposes minimum cubic capacity rules to effectively counter very light, fluffy shipments that take up more than their fair share of a trailer. Most LTL carriers in the cubic capacity rules do not kick in unless the total shipment is over 750 cubic feet and has a density of less than 6 lbs per cubic feet. Some carriers are even as low as 350 cubic feet. When your shipment hits the cubic capacity rule the carriers will levy hefty additional cubic capacity fees to your freight invoice. ExFreight’s Exfresso rating system automatically calculates if your is at any carrier’s cubic capacity, and will disqualify carriers if your freight is over the limit saving you additional fees. You can, rest assured that a rate in the ExFresso platform is correct and valid.
