To estimate your shipment, use the Duct Hose Freight Class Calculator.
The Duct Hose Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 125 to 400.
These are density-based estimates.

Duct Hose shipment examples
These examples use finished packaged dimensions and the site’s density-to-class chart. They are examples only, not fixed classes for every duct hose shipment.
Abrasion-resistant ducting tightly coiled and boxed
48 × 40 × 24 in
Packaged weight: 200 lb
Estimated class
Density-based
125
Thicker polyurethane walls and wire helix add enough weight to a compact package to produce the lower end of the example range.
PVC and polyurethane ducting layered with separators
48 × 40 × 40 in
Packaged weight: 200 lb
Estimated class
Density-based
200
Different diameters and helix stiffness create large voids between coils, reducing pallet density and raising the class.
Large collapsed ducting in protective cartons or a crate
60 × 48 × 48 in
Packaged weight: 120 lb
Estimated class
Density-based
400
The lightweight fabric occupies substantial protected cube even when collapsed, producing a very high density-based class.
Duct Hose shipment comparison
Duct hose is often low-density freight. Abrasion-resistant polyurethane hose can be relatively heavy, while fabric ventilation ducting and large wire-helix hose occupy broad coils that require crush protection and considerable trailer space.
| Duct Hose shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Abrasion-resistant polyurethane duct hose | Banded coils in cartons or on a protected pallet | Medium | Limited | Thicker walls and helix add weight to a compact coil. |
| Mixed PVC and polyurethane duct hose | Layered coils with separators and wrap | Low to medium | Limited | Different diameters and helix pitch create substantial voids. |
| Large wire-helix ventilation hose | Oversized coil, cradle, or crate | Low | Usually non-stackable | Minimum bend radius and crush protection determine the footprint. |
| Light fabric or coated-fabric ducting | Large cartons, bags, or a light crate | Very low | Depends on container strength | Light material can occupy substantial cube even when collapsed. |
Duct Hose shipping options
Choose the service around finished coil or crate dimensions, low packaged density, crush protection, cuffs or flanges, replacement value, and whether the load can safely support freight above it.
| Duct Hose shipment | Common shipping option |
|---|---|
| Compact abrasion-resistant duct hose in strong cartons | Standard LTL |
| Mixed coils on a protected pallet with a rigid top | LTL with stackability confirmation |
| Large wire-helix coils or fabric ducting in oversized crates | LTL or volume service with exact dimensions |
| Very light, oversized, fragile, or high-value custom duct hose | Crated LTL or specialized handling |
Oversized coil diameter, low density, crush sensitivity, protruding helix, cuffs, flanges, and non-stackable packaging should be described before booking.

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.
