Medical & lab/Density or item-specific
Pharmaceutical freight class and NMFC guide
Pharmaceuticals are high-value, often temperature-sensitive, and heavily regulated. Density is only one input; chain of custody, temperature control, and liability usually decide the service.

What drives the class
The density story behind pharmaceuticals.
Pharmaceutical density depends on the product form and the packaging. Cartons of tablets are light and bulky; liquids and dense packs are heavier. Most shipments add temperature control, security, and chain-of-custody requirements that matter more than a small density difference. Controlled substances may need additional licensing and a dedicated carrier. The BOL should describe the product and the required temperature range without exposing sensitive details.

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 shipper or pallet as packed, including temperature-control packaging.
- Use gross weight with cartons, cold packs, data loggers, and pallet.
- Confirm the weight and dimensions against the carrier and security requirements.
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.
High value
Liability limits and securement matter as much as the class.
Fragile
Needs securement, cushioning, or a damage-resistant loading position.
Pack it for the rating
Packaging changes the cube before it changes the class.
- Validate the temperature packaging for the expected transit time.
- Use tamper-evident seals and document the chain of custody.

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 product and packaging.
- Confirm the temperature range and any controlled-substance requirements.
- Ask whether the carrier provides validated temperature service and liability coverage.

Add the confirmed NMFC item number before you tender the shipment. The template describes the freight; it is not a classification.
Common questions
Pharmaceuticals and the 2025 scale.
How are pharmaceuticals classified for LTL freight?
At an estimated packed density of 10–20 lb/ft³, the 2025 density scale spans Class 70–92.5. 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 pharmaceuticals?
Density or item-specific. Pharmaceutical products may be density-rated, but the packaging, temperature requirements, and controlled-substance rules can change the shipment.
How do I confirm the NMFC item for pharmaceuticals?
Confirm the item for the specific product and packaging. Confirm the temperature range and any controlled-substance requirements. Ask whether the carrier provides validated temperature service and liability coverage. Confirm the current item in ClassIT+ or with the carrier before booking.

Keep the comparison close.
Medical & 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 85–125Medical & lab
Hospital beds
Hospital beds are large, heavy, and often shipped knocked down or in sections. The handling unit, not the bed frame, decides the measured cube and the class.
Class 100–175Food & beverage
Frozen foods
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.
Class 55–70Furniture & 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.
