NMFC Class 60 applies to freight with a density between 30 and 35 pounds per cubic foot. This range captures a broad mix of industrial and automotive goods that are heavier than typical manufactured products but not as dense as raw construction materials. Common Class 60 commodities include boxed automotive parts, steel cables, packaged industrial chemicals in drums, and power tools. What these products share is a combination of meaningful weight and manageable cube — they occupy trailer space efficiently without reaching the extreme density of Classes 50 or 55. From a carrier perspective, Class 60 freight is still desirable: it contributes solid revenue per trailer foot and doesn't present unusual handling challenges. For shippers, the rates remain in the low tier of the LTL scale, making Class 60 a cost-effective classification for many manufactured goods. One nuance for Class 60 is commodity-specific NMFC item numbers. Some automotive parts and chemical products have assigned item numbers with specific class rules that may override the density scale. Shippers moving these goods should verify whether their specific commodity has a classified NMFC item — and if so, whether that item is density-based or carries a fixed class — before relying solely on a density calculation. Using the NMFTA's ClassIT tool or working with a freight classification specialist is the most reliable way to confirm the correct class for Class 60-range commodities.
Class 60 freight typically ships in cartons, drums, or on pallets and is manageable with standard pallet jacks and forklifts. Some items such as steel cable coils may require special rigging.
Stowability: Dense enough to load trailers near weight limits with moderate cube usage; most items are rectangular and palletize well, though drums and coils may require additional dunnage to prevent rolling.
Packaged chemicals and automotive parts carry moderate liability — damage or leakage can result in hazmat clean-up costs or part replacement claims. Adequate containment and labeling are essential.
Class 60 covers freight with a density between 30 and 35 pounds per cubic foot. Below 30 lbs/cu ft, freight typically moves to Class 65 or higher.
Not automatically. Classification depends on the actual density of the shipment (drum plus contents). If the calculated density falls between 30 and 35 lbs/cu ft and the commodity has a density-based NMFC item, Class 60 applies. Hazardous materials also require proper NMFC hazmat class verification.
Many automotive parts have specific NMFC item numbers with density-based class tables. The shipper calculates the density and looks up the corresponding class in the applicable NMFC item. Class 60 is a common result for densely packaged boxed parts.
Yes, when the density calculation falls in the 30–35 lbs/cu ft range. Coil packaging can create measurement complexity because of the void space in the coil's center — carriers and auditors typically use the bounding-box (longest × widest × tallest) dimensions to calculate cube.
