Appliances & electronics/Density-rated
Computer and server freight class and NMFC guide
Computers and servers are dense for electronics, especially when rack-mounted or crated. The class usually depends on the rack, crate, and whether the shipment includes monitors and accessories.

Density can move with packaging, case count, or pallet pattern, so a second measurement may land in another band.

Density-based estimate. Confirm the NMFC item, the packaging form, and any density subprovision before booking.
What drives the class
The density story behind computers & servers.
Servers and workstations pack a lot of mass into a small box, so they usually land in a denser class than consumer electronics. A rack adds structure, weight, and cube; a crate adds more of all three. The density question is whether the shipment is measured as individual cartons or as one rack. A full rack is denser than the same equipment in separate boxes, but it also needs lift equipment and a secure loading position.
Density-rated. Packaged computers and servers are generally density-rated. A rack or crate can change the handling unit substantially.
Density thresholds

The highlighted rows are the classes touched by the endpoints of the typical density estimate. A single measured density returns one class; the span is a planning range. The scale is effective July 19, 2025.

Measure it right
The handling unit is the shipment.
Carriers measure what is tendered, not the product inside the box. Use the pallet, crate, or bundle as the handling unit and include everything that travels with it.
- Measure the rack or crate as one handling unit if it ships assembled.
- Include rails, cable management, and any shipping brackets in the dimensions.
- Use gross weight with the rack, crate, and accessories.
The formula
cube = L × W × H ÷ 1,728
density = gross lb ÷ cubeRound for display only. Compare the unrounded density to the scale boundary.
Fragile
Needs securement, cushioning, or a damage-resistant loading position.
High value
Liability limits and securement matter as much as the class.
Moisture-sensitive
Needs wrap, desiccant, or a dry loading position to avoid a damage claim.
Pack it for the rating
Packaging changes the cube before it changes the class.
- Use anti-static packaging and moisture protection; electronics claims often turn on water damage.
- Label the crate with lift points and a no-stack instruction if the rack is not rated for stacking.
Don't confuse it with
Adjacent items, different answers.
The most expensive classification mistake is usually a description that sounds close but is not the item. Check these before you copy a description from another shipment.

Before you book
Make the rating defensible.
- Confirm the item for the specific equipment and packaging.
- Ask whether the rack ships as one handling unit or as separate cartons.
- Document serial numbers and existing damage before pickup.

Common questions
Computers & servers and the 2025 scale.
How are computers & servers classified for LTL freight?
At an estimated packed density of 8–15 lb/ft³, the 2025 density scale spans Class 70–100. That is a planning span derived from the endpoints of the density estimate, not a promise that every shipment lands in every class. The NMFC item and the shipment as tendered control the final class.
What is the classification basis for computers & servers?
Density-rated. Packaged computers and servers are generally density-rated. A rack or crate can change the handling unit substantially.
How do I confirm the NMFC item for computers & servers?
Confirm the item for the specific equipment and packaging. Ask whether the rack ships as one handling unit or as separate cartons. Document serial numbers and existing damage before pickup. Confirm the current item in ClassIT+ or with the carrier before booking.

Keep the comparison close.
Appliances & electronics
Flat-panel TVs
Flat-panel televisions are light, fragile, and shipped in cartons that are much larger than the screen. The carton and pallet usually decide the density, not the panel size alone.
Class 125–250Medical & lab
Medical devices
Medical devices are high-value and fragile, and the packaging is often a substantial part of the shipment. Density is secondary to securement, liability, and handling instructions.
Class 85–125Machinery & industrial
Pumps & compressors
Pumps and compressors are dense, irregular machinery. The class depends on whether the unit is crated, skidded, or shipped with accessories, fluids, and controls attached.
Class 70–92.5Appliances & electronics
Refrigerators
Refrigerators are bulky and surprisingly light for their size. Density depends on the crate or carton, the pallet, and whether the unit ships upright with doors and shelving installed.

This is an independent planning reference, not the NMFC and not a carrier classification. The typical density is an estimate. The class span is derived from the 2025 density scale. The NMFC item, the carrier tariff, and the shipment as tendered control the final rating.
