Freight Class for Boiler
To estimate your shipment, use the Boiler Freight Class Calculator.
The Boiler Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 65 to 92.5.
These are density-based estimates.

Boiler shipment comparison
Boiler Freight Class by Shipment Format
Boiler freight class can change with the enclosure size, coils or burners, fans, piping, insulation, protective clearance, and top-load restrictions. Use the finished packaged dimensions and total weight rather than the equipment's unpackaged size.
| Boiler shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Compact packaged boiler | Reinforced pallet or skid with blocking, restraint, and weather protection | Medium to higher | Limited | Dense boiler and burner secured to a reinforced skid; this example calculates to 23.33 lb/cu ft and Class 65. |
| Crated industrial boiler | Framed crate with internal restraint and protection for controls and moving parts | Medium to higher | Possible with engineered crate | Vessel, burner, controls, and fittings protected; this example calculates to 19.05 lb/cu ft and Class 70. |
| Large boiler assembly | Elongated or oversized crate with structural bracing and protective clearance | Medium to lower | Usually non-stackable | Heavy vessel with broad footprint and rigging requirements; this example calculates to 11.72 lb/cu ft and Class 92.5. |
| Equipment with fans, controls, and accessories | Main equipment skid plus separately protected controls, panels, duct pieces, pumps, or piping components | Varies | Usually limited | Accessories and protective framing can materially change the final cubic volume and density. |
Boiler shipping options
Choosing a Shipping Method for Boiler
The appropriate service depends on finished dimensions, packaged weight, piece count, loading method, value, stackability, and whether specialized handling is required.
| Boiler shipment | Common shipping option |
|---|---|
| Compact packaged boiler | Standard LTL with packaging and handling review |
| Crated industrial boiler | Partial truckload, volume LTL, or specialized service |
| Large boiler assembly | Partial truckload, volume LTL, or specialized service |
| Equipment with fans, controls, and accessories | LTL, volume, partial truckload, or dedicated service after piece-count and handling review |
Heavy, long, high-value, non-stackable, multi-piece, or rigging-dependent boiler shipments may need carrier review before booking.
Boiler Packaging, Stackability, and Damage Risk
Boiler Packaging
- Secure the cabinet, vessel, or frame to a reinforced skid and brace tall or broad enclosures.
- Protect coils, burners, fans, doors, refractory, nozzles, piping stubs, and control panels from impact.
- Cap openings and keep loose filters, panels, duct pieces, sensors, and accessories restrained and labeled.
Boiler Stackability
- Treat equipment with fans, coils, vents, piping, or uneven roofs as non-stackable.
- Only use stackable status when a separate structural frame carries the load above the equipment.
- Keep lifting points, base rails, center-of-gravity marks, and upright instructions visible.
Boiler Fragility and Liability
- Protect thin fins, insulation, refractory, doors, seals, instruments, and control components from shock and weather.
- Drain or secure approved fluids and close all service connections before shipping.
- Confirm handling and liability requirements for large, high-value, or site-critical process equipment.
Before Requesting a Boiler Freight Quote
How to Measure a Packaged Boiler Shipment
- Measure after the boiler is secured and all pallet, skid, crate, framing, guards, and protective materials are complete.
- Include runners, saddles, legs, controls, fittings, attachments, overhang, and every projecting packaged component.
- Measure to the longest, widest, and tallest finished point and use the total tendered shipment weight.
Boiler Freight Quote Checklist
- Record the finished packaged length, width, height, and total weight.
- State whether the shipment is stackable and whether top loading is prohibited.
- Include photos showing packaging, securement, labels, lift points, and exposed risk areas when practical.
- List detached controls, guards, accessories, tooling, fittings, and other separate pieces.
- Confirm forklift, dock, crane, rigging, liftgate, or specialized loading requirements.
