Shipping Packaging Materials Freight Class Guide
Packaging Materials typically classify around Class 250, in the 2-5 lb/ft³ density range. Mixed boxed void-fill and packaging supplies.
Calculate Packaging Materials Freight Class
Enter your actual shipment dimensions and weight below. Typical packaging materials run 150-300/pallet lb, but your exact class depends on your specific shipment's measured density.
Measure the full footprint including packaging, and include pallet weight in your total. Carriers will re-measure at the terminal.
Shipping Packaging Materials the Right Way
Cube-Out Defines This Freight
Packaging materials are light enough that trailers reach their cubic capacity long before weight becomes a factor, so shippers moving volume should plan around stacking height and pallet count rather than the trailer's weight rating.
Compressed Packaging Ships More Efficiently
Some void-fill products, like compressed air pillow rolls, ship far denser than their inflated form, so shipping the uninflated or compressed version whenever the buyer can inflate on site meaningfully improves density and lowers cost.
Low Weight Doesn't Mean Low Damage Risk
Bulky, lightweight cartons can still crush or tear under uneven stacking, even though the material inside weighs almost nothing, so pallets should be built with consistent box sizes on the bottom layers to avoid caving in under taller stacks.
Packaging Materials: What Carriers and Shippers Look For
Void-fill and packaging supplies, foam peanuts, bubble wrap, air pillows, and similar materials, are among the lightest, bulkiest freight on the road, running just 2 to 5 pounds per cubic foot and landing most shipments around Class 250. This is extreme cube-out territory: a full trailer of packaging materials can weigh a small fraction of its legal limit, so pallet height and stacking efficiency drive shipping cost far more than the weight ever will.
Why Packaging Materials Classify Around Class 250
Boxed void-fill and packaging supplies typically run 2 to 5 pounds per cubic foot, among the lowest densities of any common freight category. That density lands most shipments around Class 250, one of the more expensive classes on the table, which can surprise shippers focused on the low retail cost of the materials themselves. Because the category covers everything from foam peanuts to bubble wrap to air pillow systems, density can vary meaningfully within a single order, so an accurate combined pallet measurement matters more than a catalog estimate.
Packaging Tips That Protect the Class
Shipping inflatable void-fill products in their uninflated, rolled form whenever the receiving facility has inflation equipment on site dramatically improves density and can move a shipment into a noticeably cheaper class.
Compressing loose-fill materials like foam peanuts into their tightest available bag, rather than a loosely filled oversized bag, reduces wasted air space and modestly improves the pallet's overall density.
Cube-Out Planning
Because packaging materials are so light relative to their bulk, trailers hauling this freight almost always cube out well before reaching legal weight limits. Shippers moving high volumes should build pallets as tall as safe stacking allows and consolidate onto fewer pallets rather than spreading lightweight freight across more floor space than necessary.
Common Shipping Mistakes
Shipping inflated or fully expanded void-fill products instead of their compact form is the most common and costly mistake, since it wastes cubic space that direct compression or on-site inflation would have avoided.
The second mistake is underestimating how quickly this freight cubes out a trailer, which leads to underbuilt pallets and more shipments than necessary for a given order's actual weight.

“People are shocked their light foam shipment costs what it does. I explain it's cube space, not weight, and it usually clicks.”
