What Is Freight Class 85 in LTL Shipping?
Freight Class 85 is a density tier used for qualifying packaged LTL shipments that measure 12 to under 15 lb/ft³ on the current 13-tier freight density table. It sits between Class 70, which begins at 15 lb/ft³, and Class 92.5, which covers 10 to under 12 lb/ft³. In practical terms, Class 85 often describes moderately dense palletized freight that uses more trailer space per pound than Class 70 freight.
Meaning
Class 85 represents packaged freight with density from 12 up to, but not including, 15 lb/ft³.
Boundaries
15 lb/ft³ moves the density estimate into Class 70; from 10 to under 12 lb/ft³ it falls into Class 92.5.
No Fixed Weight
Class 85 is not defined by a single shipment weight. Density compares total packaged weight with the shipment's occupied cubic volume.
Freight Class 85 Density Calculation
Calculate density from the finished outside dimensions and total packaged weight, then compare the result with the current density tiers.
Measure the finished outside dimensions
Use the greatest finished length, width, and height of the handling unit. Include the pallet, crate, wrap, overhang, guards, attachments, and other projections.

Worked Freight Class 85 Example: Palletized Shelving Components
A finished 48 × 40 × 48 in handling unit occupies 53.33 ft³. At a total packaged weight of 720 lb, the density is 13.50 lb/ft³, which falls inside the Class 85 density range.

Edge Case: A Small Height Change Can Cross the Class 70 / 85 Boundary
With a 48 × 40 in footprint and 720 lb packaged weight, a 43.2 in finished height produces exactly 15.00 lb/ft³, the start of the Class 70 density tier. Increasing the height to 43.3 in lowers density to about 14.97 lb/ft³, which moves the density-based estimate into Class 85.

The calculator is preloaded with the 48 × 40 × 48 in, 720 lb Class 85 example above. Change any dimension or the weight to see how density and estimated class change.
What changes the result?
- More packaged volume with the same weight lowers density and can move the estimate to a higher-numbered class.
- More weight within the same packaged volume raises density and can move the estimate to a lower-numbered class.

What changes: In the illustrated example, both shipments weigh 720 lb and use a 48 × 40 in footprint. Increasing finished height from 36 to 48 in increases occupied volume from 40.00 to 53.33 ft³, lowering density from 18.0 to 13.5 lb/ft³ and moving the density-based estimate from Class 70 to Class 85.

With occupied volume held constant, the lighter shipment has substantially lower density and falls into the Class 85 density tier.

The 12 lb/ft³ boundary separates these tiers: exactly 12.0 remains Class 85, while a lower density moves into Class 92.5.

At identical dimensions, reducing packaged weight lowers density enough to move the estimate from Class 85 to Class 100.
Handling, Stowability & Liability for Class 85
Density is an important classification input, but Class 85 freight still needs to be evaluated for handling, stowability, liability, and any applicable commodity or NMFC provisions.
Handling
A Class 85 density result does not guarantee ordinary handling. Check total weight, stability, lift points, projections, restricted orientation, and whether standard dock equipment can safely move the finished unit.
Stowability
Regular, stackable handling units generally use trailer space more efficiently. Overhang, irregular shapes, non-stackable tops, or space restrictions can reduce stowability even when density falls squarely in Class 85.
Liability & Risk
Freight class and risk are not the same thing. Damage susceptibility, unusual value, hazardous characteristics, perishability, or the potential to damage adjacent freight can still affect the final classification.
Classification takeaway: A 12 to under 15 lb/ft³ density result supports a Class 85 estimate, but the finished shipment still needs to be evaluated under any applicable classification provisions.
How Packaging Can Change Freight Class 85
Freight density uses the finished handling unit, not just the product inside it. Taller cartons, pallet overhang, protective framing, loose packing, or other changes that increase occupied volume can lower density even when packaged weight stays the same.

Class 85 takeaway: The product and packaged weight can stay identical while a larger finished handling unit lowers density enough to change the density-based class estimate.
How to Avoid Reclassification and Billing Adjustments
Accurate finished measurements and documentation reduce avoidable classification disputes.
Near a Class 85 boundary: A shipment can move into Class 70 at 15 lb/ft³ or into Class 92.5 from 10 to under 12 lb/ft³ when finished dimensions or packaged weight change.
Measure finished dimensions — include overhang, projections, guards, and the tallest and widest points.
Verify packaged weight — include the pallet, crate, wrap, and protective materials.
Confirm the commodity description — use the applicable NMFC item and subprovision when required.
Record handling characteristics — stackability, overhang, special handling, and handling-unit count.
Keep supporting documentation — measurements and photographs of the freight as tendered.
Recalculate after changes — packaging, pallet, dimension, or weight changes can alter density.
Carrier verification: These steps improve the shipment record but do not prevent inspection, reweighing, remeasurement, or classification review.
What Is the NMFC Code for Freight Class 85?
Freight Class 85 is not an NMFC item number. An NMFC item number identifies a commodity or provision; Class 85 is a possible classification result for a qualifying shipment.
No universal code. Class 85 does not map to one NMFC item number.
Commodity-specific. NMFC items identify particular commodities and applicable provisions.
Shared result. Different shipment types can produce the same Class 85 density-based result.
Is Freight Class 85 Hazmat?
No. Freight Class 85 does not automatically mean a shipment is hazardous.
Freight class and hazmat are separate systems.
A Class 85 shipment can be hazardous or non-hazardous.
Hazmat status depends on the actual material and applicable rules.
For regulated freight: verify the material, packaging, required marks/labels, shipping description, and documentation before tender.
