Mastering Logistics: Freight Class for Used Car Engines
As an expert auto parts seller or professional mechanic, shipping used car engines across state lines is a frequent challenge. While the industry standard usually points to **NMFC code 120790**, determining the specific **freight class for used car engines** is not always straightforward. This definitive guide clarifies how dimensions, packaging, and density (PCF) impact your shipping rates in 2026.
Crated (Class 70) vs. Palletized (Class 85)
The level of protection you provide to the car engine significantly dictates the carrier's liability and risk assessment.
When you ship a used car engine, you can expect different classifications based on your packing method. A **crated used engine**—fully encased in wood—typically qualifies for **Freight Class 70**. This is because it is easily stackable and well-protected. However, the most common shipping method is simply strapping the engine to a 40x48 pallet. Because this leaves engine components exposed and creates non-stackable space, the carrier usually applies **Freight Class 85**.
How to Measure Standard Engine Block Dimensions
Carriers use your **Pounds per Cubic Foot (PCF)** density to verify your class. If your density is low, even a crated engine could be pushed to a higher class. To avoid costly re-weigh and re-class inspection fees, you must measure carefully. Use the furthest points of the crate or pallet, not just the block itself.
- Length: Tip to tip of the pallet/crate base.
- Width: Widest point of the shipping unit.
- Height: From the floor to the absolute highest point (exhaust manifold, lifting eyes).
By accurately calculating these dimensions using our integrated **freight class for used car engines** tool, you eliminate the guesswork and protect your profit margins from carrier billing adjustments.
