Medical & lab freight classes and NMFC guide
Medical and lab freight is high-value and often temperature-sensitive. Density can be moderate, but liability, chain of custody, and temperature control usually drive the shipping decision.

What changes the class inside this category.
The class is not set by the category name. It is set by the form, packaging, and handling unit of the specific commodity. These are the variables that move a shipment between tiers.

What to watch
- Temperature-controlled service and data logging may be required.
- High-value liability limits and securement need a pre-booking check.
- Regulated medical waste and sharps are outside normal LTL.
Start with the document, not the class. The NMFC item controls the description and any special provision. Confirm it in ClassIT+ or with the carrier, then measure the handling unit.

3 entries
| Commodity | Basis | Typical density | Class span | Risk |
|---|---|---|---|---|
| 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. | Mixed | 4–8 lb/ft³ | Class 100–175 | High |
| 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. | Mixed | 6–12 lb/ft³ | Class 85–125 | High |
| Pharmaceuticals 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. | Mixed | 10–20 lb/ft³ | Class 70–92.5 | High |
Class spans are derived from the endpoints of each typical density estimate. A measured shipment returns one class. Methodology & sources.

Measure the shipment, not the category.
Use the freight class calculator for the density math, the pallet calculator for the finished handling unit, and the linear feet calculator for trailer floor space.

Furniture & fixtures
Furniture is one of the hardest categories to classify because the same item can ship assembled, knocked down, or nested. Density, packaging, and whether the carrier can stack the handling unit usually decide the class.
Browse category →Appliances & electronics
Appliances and electronics are bulky relative to their weight, so density usually lands in the middle of the scale. The packaging — foam, crates, and pallets — often matters more than the product itself.
Browse category →Building materials
Building materials are usually dense and stable, which makes them easier to classify than furniture. The trap is shipping partial units, mixed loads, or material that is wet, wrapped, or bundled differently from the norm.
