Carrier Dimensional Pricing Expansion Beyond Core Zones
FedEx and UPS have steadily lowered the parcel size threshold at which dimensional weight pricing applies, a policy shift that now captures small and mid-size parcels that previously shipped by actual weight. USPS has signaled similar changes under its Ground Advantage service restructuring. Each threshold reduction raises the financial penalty for excess void space inside a shipped carton, which pushes fulfillment operators to adopt inline air cushion systems that inflate film to the exact dimensions needed rather than stocking oversized pre-made cushions. Smaller shippers who previously tolerated loose-fill peanuts are now the fastest-growing buyer segment as the threshold keeps dropping. MMA estimates the loose-fill peanuts market will be worth USD 0.82 billion by 2036.
