Freight Class Density Chart (2026)
Use this table as a quick reference for the standard density-based NMFC scale. Actual classification can still depend on the applicable NMFC item, handling, stowability and liability.
| Density (lb/ft³) | Density-based class |
|---|---|
| Less than 1 | 400 |
| 1 to < 2 | 300 |
| 2 to < 4 | 250 |
| 4 to < 6 | 175 |
| 6 to < 8 | 125 |
| 8 to < 10 | 100 |
| 10 to < 12 | 92.5 |
| 12 to < 15 | 85 |
| 15 to < 22.5 | 70 |
| 22.5 to < 30 | 65 |
| 30 to < 35 | 60 |
| 35 to < 50 | 55 |
| 50 or greater | 50 |
