Lumber shipment comparison
Lumber is often dense but can create long, narrow, or irregular freight that requires careful banding and forklift support. Species, moisture content, board dimensions, bundle density, length, and whether the wood is surfaced, finished, or loose all affect the shipment profile.
| Lumber shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Dimensional softwood lumber | Squared bundle with dunnage and bands | Very high | Usually stackable | Keep ends aligned and bands tensioned across solid blocking. |
| Hardwood boards | Wrapped and banded bundle | Very high | Usually stackable | Protect finished faces, edges, and moisture-sensitive stock. |
| Long trim or specialty boards | Long narrow bundle or crate | High | Limited | Support the full length and prevent bowing or forklift damage. |
| Mixed or loose lumber pieces | Crate, rack, or contained bundle | Medium | Limited | Separate lengths and prevent shifting or protruding ends. |
lumber shipping options
The right service depends on lumber size, packaging, stackability, and handling needs.
| Lumber shipment | Common shipping option |
|---|---|
| Standard dimensional lumber bundle | Flatbed, volume, or LTL by size |
| Hardwood or finished-board bundle | Protected LTL or dedicated service |
| Long specialty lumber or trim | Long-freight or flatbed service |
| Oversized building-material package | Volume, flatbed, or dedicated service |
Large, irregular, non-stackable, unusually valuable, or specially handled lumber shipments may need carrier review before booking.

Calculate your actual shipment
The calculator returns cubic feet, pounds per cubic foot, and a density-based freight class estimate for your lumber shipment.
Freight classes shown on this page are density-based estimates for shipment planning. Actual classification may also depend on value, handling requirements, liability, stowability, dimensions, and other commodity-specific factors. Confirm the final freight class with your carrier, broker, or official NMFC resources before shipping.
