Furniture & fixtures/Density or item-specific
Wood cabinet freight class and NMFC guide
Cabinets are dense for furniture but awkward to pack. Assembled cabinets, flat-pack cabinets, and vanity tops can follow different density paths and different NMFC items.

Density-based estimate. Confirm the NMFC item, the packaging form, and any density subprovision before booking.
What drives the class
The density story behind wood cabinets.
Cabinet density depends on what is inside the box. A flat-pack cabinet is mostly air, panels, and hardware, so it lands in a lighter class. An assembled cabinet with shelves, doors, and a counter adds mass without much extra cube and moves toward a denser class. Height and overhang matter because cabinet boxes are often taller than a standard pallet. Measure the finished handling unit, not the cabinet carcass alone.
Density or item-specific. Assembled cabinets and knocked-down cabinets can classify differently. Density often applies once the handling unit is built.
Density thresholds
Where the estimate sits on the 2025 scale.
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 full cabinet box or crate, including doors, handles, and toe kicks.
- Use gross weight with the pallet, crate, and any countertop packed with the unit.
- Measure assembled and flat-pack shipments separately; do not average them into one line.
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.
Moisture-sensitive
Needs wrap, desiccant, or a dry loading position to avoid a damage claim.
Oversize / bulky
Long, tall, or irregular handling units can affect stowability and linear feet.
Pack it for the rating
Packaging changes the cube before it changes the class.
- Cardboard corners and foam add cube, but they are part of the shipment the carrier measures.
- Keep cabinets dry and off the trailer floor; moisture damage is a common claim.
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 assembled versus knocked-down cabinets.
- Confirm whether a packed countertop is part of the same handling unit.
- Photograph the crate and any overhang before pickup.

Common questions
Wood cabinets and the 2025 scale.
How are wood cabinets classified for LTL freight?
At an estimated packed density of 5–9.5 lb/ft³, the 2025 density scale spans Class 100–175. 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 wood cabinets?
Density or item-specific. Assembled cabinets and knocked-down cabinets can classify differently. Density often applies once the handling unit is built.
How do I confirm the NMFC item for wood cabinets?
Confirm the item for assembled versus knocked-down cabinets. Confirm whether a packed countertop is part of the same handling unit. Photograph the crate and any overhang before pickup. Confirm the current item in ClassIT+ or with the carrier before booking.

Furniture & fixtures
Bookcases
Bookcases are light for their height and easy to tip. The density question is usually about packaging and whether the unit ships assembled, flat-packed, or with glass shelves.
Class 100–175Furniture & fixtures
Sofas & sectionals
Upholstered seating is bulky and easy to under-measure. A sofa that ships assembled, knocked down, or as a modular sectional can land in different density bands.
Class 125–175Furniture & fixtures
Mattresses
Mattresses are bulky and light for their cube, so packed density usually lands in the low single digits. Compression, pallet height, and overhang move the result more than the mattress type.
Class 175–250Automotive
Tires
Tires are bulky and awkward, and new, used, and baled tires can follow different classification paths. Density depends heavily on whether the tires are loose, stacked, banded, or baled.

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.
