LTL freight classifications are changing! Classification (and charges) is based on density of freight: heavier items are more expensive to ship, but increased volume is a pricing factor as well. This means a single pallet of bowling balls will be priced differently than a single pallet of pillows, even if both weigh 1000 pounds (in short, because the pillows take up more space). Freight carriers are simplifying pricing and that will make high volume, low density goods like pillows more expensive to ship. Since density of higher volume goods will have more effect in the new calculation, optimizing your brand's packaging will be the clearest way to keep your costs down. So find a way to fit more items in those case packs.

How changes will impact shippers
C.H. Robinson is using AI agents to navigate reclassification
UPS revised its Ground Saver (formerly SurePost) service eligibility in June. If you like using this service to save money on low-cost, lightweight packages that can ship a little slower, you'll want to be aware of how this affects your shipping mix and maybe consider alternatives. High volume shippers can negotiate these rates, while lower volume shippers need to abide by the rules to avoid surcharges and penalties - they could also see their packages reclassified into a higher tier of shipping or rejected.
