Shipping machinery is different from shipping boxed or palletized goods. Machinery varies in size, weight, and packaging. Because of that, it often falls into a wide range of freight classes. Understanding how freight class for machinery works can help you avoid re‑class fees, chargebacks, and unexpected shipping costs.
Below is a simple guide to help you understand machinery freight classes and when your shipment may qualify for linear‑foot pricing instead of freight class.
Machinery is a density-based item, meaning its freight class depends on how much space it occupies compared with its weight. The most important factors include:
Most machinery ships between Class 70 and Class 400. Higher density typically results in a lower, cheaper freight class. Lower density or oversized pieces will fall into higher classes.
Since machinery comes in all shapes and sizes, calculating density is the best way to estimate the correct class before booking.
Not every shipment needs a freight class. Some carriers, especially regional carriers and owner‑operators, offer linear‑foot pricing instead of traditional LTL class-based rates.
Carriers charge based on:
With this method, freight class does not affect the price.
Linear‑foot pricing is ideal when:
Many machinery shippers choose this option because it eliminates class disputes and prevents re‑class fees.
Here’s a quick guide:
| Shipment Type | Best Option |
|---|---|
| Dense, crated machinery on standard pallets | LTL with density-based freight class |
| Oversized or bulky equipment | Linear‑foot pricing with regional carriers or owner-operators |
| Equipment requiring open-deck trailers | Flatbed, step‑deck, or hotshot |
| High-value or sensitive machinery | Specialized machinery movers |
If your freight doesn’t fit neatly into an LTL category, open‑deck or linear‑foot pricing can offer better value and fewer complications.
You can save money and avoid issues by following a few best practices:
Taking these steps helps carriers provide accurate pricing and reduces the chance of billing adjustments.
