Freight Class 150
Class 150 used to cover 6–7 lb/ft³ goods such as auto body panels, bookcases and truck caps. Since the July 2025 NMFC change it has no density band — that density now rates class 125.
What is class 150 freight?
Class 150 is one of the higher NMFC classes, for large goods that are light for their size. Until July 19, 2025, it covered 6 to just under 7 pounds per cubic foot: truck caps, bookcases, auto body panels. The 2025 scale has no 150 step. Freight at that density is now class 125, which costs less, and class 150 comes only from an item's own NMFC listing.
What happened to class 150 in 2025
Before the mid-2025 change, class 150 took freight from 6 to just under 7 lb/ft³. That band was home to large, flat, awkward goods: auto body panels, flat-packed bookcases, cased furniture, pickup truck caps. The new scale gave the whole 6–8 range to class 125 and left 150 with no density band at all. A class 150 rating can still come from an item's NMFC listing, for goods that are hard to handle or stow. Density alone can no longer produce it.
If you shipped this freight before mid-2025, re-check your quotes: a pallet that billed at 150 may now bill at 125 if it is density-rated. If your commodity's NMFC listing names class 150, that listing still applies. Your carrier can confirm which case you are in.
Class 150 worked examples
Two former class 150 loads that rate 125 today, and one that a ragged top layer sends to 175.
Pickup truck cap — now class 125
A fiberglass truck cap on a frame, 78" × 65" × 22", 420 lb crated.
78 × 65 × 22 = 111,540 in³ ÷ 1,728 = 64.5 ft³. Density = 420 lb ÷ 64.5 ft³.
6.5 lb/ft³ → class 125 now (150 under the old table).
Flat-packed bookcases on a pallet — now class 125
Boxed knock-down bookcases stacked 45" high on a 48" × 40" pallet, 330 lb.
48 × 40 × 45 = 86,400 in³ ÷ 1,728 = 50.0 ft³. Density = 330 lb ÷ 50.0 ft³.
6.6 lb/ft³ → class 125, down from 150.
The same bookcases, stacked unevenly to 52" — class 175
The identical 330 lb of cartons with a ragged top layer that peaks at 52".
48 × 40 × 52 = 99,840 in³ ÷ 1,728 = 57.8 ft³. Density = 330 lb ÷ 57.8 ft³ = 5.7 lb/ft³ — under the 6 line.
5.7 lb/ft³ → class 175. Seven inches of uneven top moved it from class 125 straight to 175.
The new risk: falling to class 175
Flat freight near the old 150 band now has two edges: 6 and 8 lb/ft³. From 8 up the shipment reaches class 100; below 6 it falls to class 175, because class 150 no longer sits in between. So the risk now sits on the low side. A flat-freight unit at 6.2 lb/ft³ has little room, and a sloppy stack can jump it straight from 125 to 175.
Flat freight rewards flat thinking. Panels cased upright in an A-frame measure tall and mostly empty; the same panels layered flat measure what they are. Keep the top of the stack level too, because carriers dimension to the highest point. Wide, thin goods also flex, and a bowed case measured at its corners bills bigger than its contents. Corner boards and banding keep the measured size at the design size.
What used to ship at class 150
These goods often rated 150 under the old table. Today their class comes from their NMFC listing or their measured density:
- Auto sheet metal parts
- Bookcases
- Assembled wood furniture
- Pickup truck caps

Enter the size and weight as shipped. From 6 to just under 8 lb/ft³ is class 125. Just under 6, the next step is class 175, so measure to the tallest point of the load.

Frequently asked questions
What does class 150 mean for my freight today?
If your freight is rated by density, the old class 150 range (6–7 lb/ft³) is class 125 now, one step cheaper. If your item's NMFC listing names 150, you still ship at 150. Your carrier can tell you which case applies.
Does freight class 150 still exist?
Yes, but you only meet it through an item's NMFC listing. Since July 19, 2025, weight and size alone can't put freight in class 150; 6 to just under 8 lb/ft³ is class 125.
What density was freight class 150?
It covered 6 to just under 7 lb/ft³ before July 19, 2025. On today's scale, class 125 takes everything from 6 to just under 8.
What freight class is flat-packed furniture now?
If it is density-rated, it depends on the measured pallet: 6 to under 8 lb/ft³ is class 125, 8 to under 10 is class 100, and under 6 is class 175. Assembled furniture usually measures far lighter. Some furniture items carry their own NMFC listing, so confirm with your carrier.
