Food & beverage/Density-rated
Frozen food freight class and NMFC guide
Frozen food is dense and usually easy to rate, but the shipment only works if the cold chain holds. Temperature service, loading time, and pallet configuration matter more than the class.

What drives the class
The density story behind frozen foods.
Frozen food density is driven by the product and the case pack. A pallet of frozen vegetables is less dense than a pallet of solid frozen blocks, but both are usually in a workable range. The classification risk is low; the cold-chain risk is high. A dry van will not do. The carrier needs reefer service, a pre-cooled trailer, and a delivery window that keeps the product frozen. A temperature excursion can ruin the load even if the class is correct.
Density-rated. Frozen food is generally density-rated. The temperature service and delivery window are separate from the class.
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 pallet as loaded, including cases, wrap, and any temperature logging equipment.
- Use gross weight with packaging and pallet.
- Confirm the pallet height and weight against the reefer trailer and lift limits.
The formula
cube = L × W × H ÷ 1,728
density = gross lb ÷ cubeRound for display only. Compare the unrounded density to the scale boundary.
Temperature-sensitive
May need reefer, heated, or protected service rather than a dry van.
Pack it for the rating
Packaging changes the cube before it changes the class.
- Keep the pallet tight and stable; frozen cases can become slippery.
- Use temperature monitoring and document the reefer set point on the BOL.
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 frozen product and packaging.
- Confirm the required temperature range and delivery window.
- Ask whether the carrier provides reefer service and temperature records.
BOL description template
Starting pointFrozen [product], [quantity] cases per pallet, [number] pallets, [gross weight] lb gross, [length x width x height] in per pallet, maintain [temperature] F.
Add the confirmed NMFC item number before you tender the shipment. The template describes the freight; it is not a classification.
Common questions
Frozen foods and the 2025 scale.
How are frozen foods classified for LTL freight?
At an estimated packed density of 20–35 lb/ft³, the 2025 density scale spans Class 55–70. 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 frozen foods?
Density-rated. Frozen food is generally density-rated. The temperature service and delivery window are separate from the class.
How do I confirm the NMFC item for frozen foods?
Confirm the item for the specific frozen product and packaging. Confirm the required temperature range and delivery window. Ask whether the carrier provides reefer service and temperature records. Confirm the current item in ClassIT+ or with the carrier before booking.
Related commodities
Keep the comparison close.
Food & beverage
Canned goods
Canned goods are dense, stackable, and usually straightforward. The class depends on the can size, the case pack, and whether the pallet is a mixed SKU load.
Class 55–60Food & beverage
Bottled water
Bottled water is heavy, stable, and usually easy to classify. The main variables are the case count, the pallet pattern, and whether the shipment is shrink-wrapped or in trays.
Class 55–65Food & beverage
Wine
Wine is dense for its cube but fragile and often temperature-sensitive. The class is usually manageable; the licensing, temperature, and breakage rules are the hard part.
Class 55–65Furniture & 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 175–250Sources & limits
What this page is, and what it is not.
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.
