This is a density-based estimate using the 13-subprovision density scale from NMFC Docket NMFC-2025-1. Actual classification is also affected by handling, stowability, and liability characteristics, and the density scale applies only when those issues are absent. Your carrier makes the final call.
| Sub | Density (lb/ft³), as published | Class |
|---|---|---|
| 1 | Less than 1 | 400 |
| 2 | 1 but less than 2 | 300 |
| 3 | 2 but less than 4 | 250 |
| 4 | 4 but less than 6 | 175 |
| 5 | 6 but less than 8 | 125 |
| 6 | 8 but less than 10 | 100 |
| 7 | 10 but less than 12 | 92.5 |
| 8 | 12 but less than 15 | 85 |
| 9 | 15 but less than 22.5 | 70 |
| 10 | 22.5 but less than 30 | 65 |
| 11 | 30 but less than 35 | 60 |
| 12 | 35 but less than 50 | 55 |
| 13 | 50 or greater | 50 |
Class 70 covers freight from 15 lb/ft³ up to but not including 22.5 lb/ft³. The span is 7.5 pounds per cubic foot, more than three times the width of the bands in the middle of the scale, and it ties with the band above it as the second widest of the thirteen.
Class 70 by the numbers
Class 70 is subprovision 9 of 13 in the current scale, and NMFTA's published wording for it is "15 but less than 22.5".
The band one step lighter is class 85 (12.00 ≤ density < 15.00 lb/ft³). The band one step denser is class 65 (22.50 ≤ density < 30.00 lb/ft³).
It spans 7.50 lb/ft³, wider than 8 of the other 10 bounded bands in the scale.
In a handling unit measuring 40 × 48 × 48 in — about 53.33 ft³, an illustrative size rather than a standard pallet specification — class 70 covers shipments weighing 800.00 lb or more but less than 1200.00 lb.
A band 7.5 pounds wide
Wide bands are not generous bands. A 7.5-pound span means a shipment has to change density a great deal before its class moves at all, so two loads with visibly different cargo can share class 70 while having little else in common. The band absorbs that variation by design.
The upper bound is 22.5, the only fractional density boundary in the whole scale. It matters for the same reason every boundary matters: a density of exactly 22.5 lb/ft³ belongs to the band above, class 65, and not to this one.
Frequently asked
Is 22.5 lb/ft³ class 70 or class 65?
Class 65. The interval for class 70 ends below 22.5, so a density of exactly 22.5 lb/ft³ is the first density in the 22.5-to-30 band.
Why is this band so wide?
The published scale widens as density rises, finishing with a fifteen-pound band above 35 lb/ft³. Wide upper bands mean fewer available class changes for very dense freight.
