Power Supply LTL Shipping Guide
Freight Class for Power Supply
To estimate your shipment, use the Power Supply Freight Class Calculator.
The Power Supply Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 70–92.5.
These are density-based estimates.

Power Supply shipment comparison
Power Supply Freight Class by Shipment Format
Power Supply freight class can change with finished packaging, density, weight distribution, protective clearance, and stackability. Use the finished packaged dimensions and total weight rather than the unpackaged product size.
| Power Supply shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| DIN-rail power supply cartons | Cartons of compact power supplies on a pallet | Moderate | Stackable | Use anti-static packaging and keep terminals protected. This example calculates to 18.00 lb/cu ft and Class 70. |
| Rack power system | Crated rack-mount power supply and modules | Medium to lower | Limited | Cushion electronics and separate removable modules. This example calculates to 11.70 lb/cu ft and Class 92.5. |
| Industrial DC power cabinet | Palletized power-supply cabinet | Medium to lower | Non-stackable | Anchor the cabinet, secure doors, and protect fans and control interfaces. This example calculates to 11.59 lb/cu ft and Class 92.5. |
| Multi-piece or accessory shipment | Main power supply package plus separately protected components, accessories, or mounting hardware | Varies | Confirm each piece | List every separate piece and include its finished dimensions, weight, packaging, and stackability in the quote request. |
Power Supply shipping options
How Shipping Method Affects Power Supply Freight Class
The appropriate service depends on finished dimensions, packaged weight, piece count, loading method, value, stackability, and whether specialized handling is required.
| Power Supply shipment | Common shipping option |
|---|---|
| DIN-rail power supply cartons | LTL with packaging, stackability, and handling review |
| Rack power system | LTL with packaging, stackability, and handling review |
| Industrial DC power cabinet | LTL with packaging, stackability, and handling review |
| Multi-piece, high-value, or special-handling shipment | LTL, volume, partial truckload, dedicated, or specialized service after piece-count and handling review |
Compact units may move parcel or palletized LTL; rack and cabinet systems should use protected LTL.
Power Supply Packaging, Stackability, and Damage Risk
Power Supply Packaging
- Anti-static cushioning, terminal covers, module restraint, and fan/connector protection.
- Use anti-static packaging and keep terminals protected.
- Cushion electronics and separate removable modules.
Power Supply Stackability
- Stackable with even carton loading.
- Limited stacking in a rigid crate.
- Non-stackable.
Power Supply Fragility and Liability
- Impact to boards and connectors, moisture, and hidden vibration damage.
- Anchor the cabinet, secure doors, and protect fans and control interfaces.
- Confirm declared value, coverage, orientation, and any top-load or special-handling restrictions before tendering power supply freight.
Before Requesting a Power Supply Freight Quote
How to Measure a Packaged Power Supply Shipment
- Measure after the power supply is secured and all cartons, pallets, skids, crates, framing, and protective materials are complete.
- Include runners, legs, reels, doors, fittings, cables, brackets, accessories, overhang, and every projecting packaged component that applies.
- Measure to the longest, widest, and tallest finished point and use the total tendered shipment weight.
Power Supply Freight Quote Checklist
- Record the finished packaged length, width, height, quantity, and total weight.
- State whether the shipment is stackable and whether top loading or side loading is restricted.
- Include photos showing packaging, securement, labels, lift points, and exposed risk areas when practical.
- Describe the exact power supply shipment format and list detached components, accessories, cables, mounting hardware, or separate pieces.
- Confirm forklift, dock, liftgate, crane, rigging, inside-delivery, or specialized loading requirements.
Freight Planning Calculators
