Freight Class 77.5
Class 77.5 used to cover 13.5–15 lb/ft³ freight such as tires and bathroom fixtures. Since the July 2025 NMFC change it has no density band — that density now rates class 85.
Class 77.5 at a glance
Class 77.5 is still one of the 18 NMFC freight classes, but since July 19, 2025 it has no band on the density scale. Freight that measures 13.5 to just under 15 pounds per cubic foot now rates class 85. Class 77.5 is reached only through specific NMFC commodity listings.
Density scale none since July 19, 2025 (was 13.5 to under 15 lb/ft³; now class 85)
- Old density band — 13.5 up to just under 15 lb/ft³. On the current NMFC scale that density is class 85.
- Still a real class — a specific NMFC commodity listing can assign 77.5 directly, whatever the density.
- Class 70 starts at 15 lb/ft³ — on a 48 by 40 by 48 inch pallet, that is 800 lb.

What is class 77.5 freight?
Class 77.5 is one of the 18 NMFC classes, between 70 and 85. Until July 19, 2025, it was the class for freight that weighed 13.5 to just under 15 pounds per cubic foot, such as tires, bathroom fixtures and boxed hardware. The new density scale skipped it. That same freight now rates class 85, one step more expensive, unless its own NMFC listing names 77.5. If you used to ship at 77.5 by density, check your recent quotes.
What happened to class 77.5 in 2025
The old density table had 18 rows, and one of them was class 77.5: 13.5 to just under 15 pounds per cubic foot. NMFC Docket 2025-1, in force since July 19, 2025, cut the table to 13 tiers and dropped that row. Class 85 now stretches from 12 all the way to 15 lb/ft³, so the old 77.5 slice sits inside it. The class number stayed in the NMFC. A commodity can still be listed at 77.5 because of how it handles or stows, just not because of what it weighs per cubic foot.
So there are now two separate questions. If your freight is density-rated, a load that used to rate 77.5 now rates 85 — one class step higher. If your commodity's NMFC listing names class 77.5, that listing still applies no matter what a density calculator says. Ask your carrier which one governs before you quote a lane you ship often.
Class 77.5 worked examples
Two loads that rated 77.5 under the old table and rate 85 now. The third shows how a little extra weight on the same pallet reaches class 70.
Palletized packaged hardware — now class 85
Cases of packaged hardware on a 48" × 40" pallet, 40" high, 640 lb.
48 × 40 × 40 = 76,800 in³ ÷ 1,728 = 44.4 ft³. Density = 640 lb ÷ 44.4 ft³.
14.4 lb/ft³ → class 85 on the current NMFC scale (the pre-2025 table said 77.5).
Rolled wall coverings, boxed upright — now class 85
Cartons of covering rolls standing on a 48" × 40" pallet, 36" high, 560 lb.
48 × 40 × 36 = 69,120 in³ ÷ 1,728 = 40.0 ft³. Density = 560 lb ÷ 40.0 ft³.
14.0 lb/ft³ → class 85 (pre-2025 table: 77.5).
The hardware pallet, 40 lb heavier — class 70
The identical 44.4 ft³ pallet with gap-filling boxes of fasteners added, 680 lb total.
Density = 680 lb ÷ 44.4 ft³ = 15.3 lb/ft³ — over the 15 lb/ft³ line.
15.3 lb/ft³ → class 70. Forty pounds of freight you were shipping anyway, a full class step cheaper than 85.
The 15 lb/ft³ line matters more now
Because the density scale now jumps straight from class 70 to class 85, freight sitting just under 15 lb/ft³ gives up a full class step. Load hollow goods to use their hollows: lace tires in columns so each tire's shoulder sits in the next one's cavity, fill the gaps between large light cartons with small heavy ones, and stand roll goods on end. Each trick adds weight to the same cube or takes cube off the same weight, and at 14-and-something lb/ft³ either one can tip the unit over 15 and into class 70.
Then keep the load measuring the way you quoted it. Hollow and padded goods deform: a strapped stack that bulges an inch on each side, or a soft top carton that domes upward, inflates the measured cube. Rigid corners, tight banding and honest dimensions keep the carrier's measurement and your quote telling the same story.
Goods that used to ship at class 77.5
These were typical class 77.5 goods under the old table. Today each one follows its own NMFC listing or its measured density:
- Tires and tubes
- Bathroom fixtures
- Packaged hardware
- Wall and floor coverings

What does your old 77.5 load rate today?
Enter the pallet or carton size and weight. From 12 to just under 15 lb/ft³ is class 85. Pass 15 and it is class 70. The result also shows the old table's class.

Frequently asked questions
Is there a freight class 75?
No. There is no class 75 in the NMFC. People who search for it usually mean class 77.5, which sits between 70 and 85. The 18 classes are 50, 55, 60, 65, 70, 77.5, 85, 92.5, 100, 110, 125, 150, 175, 200, 250, 300, 400 and 500.
Does freight class 77.5 still exist?
Yes. It is still one of the 18 NMFC classes, but no density reading can reach it now. Only an item's own NMFC listing can put freight at 77.5. Rated by density, 13.5–15 lb/ft³ is class 85 today.
What density was freight class 77.5?
Under the pre-July-2025 table: 13.5 to just under 15 lb/ft³. That range now sits inside class 85 (12 to just under 15). At 15 lb/ft³ and up, the load is class 70.
What freight class are tires now?
It depends on the tires' current NMFC listing. Tires were traditionally rated around 77.5 because laced stacks often measured 13.5–15 lb/ft³. If your tires are density-rated, that density is class 85 today, and a tighter stack over 15 lb/ft³ is class 70. Confirm the item with your carrier.
