Shipping freight shouldn’t feel like decoding a secret language — but between freight classes, dimensional weight, and fluctuating rates, it often does.

At Seashore Transportation, we believe in transparency, simplicity, and helping our clients make smart, informed decisions. So here it is — a jargon-free breakdown of freight class, weight, and rates that won’t give you a migraine.

📦 What Is Freight Class (and Why It Matters)?

Freight class is a standardized way to categorize shipments, determined by the National Motor Freight Traffic Association (NMFTA). It affects how much it costs to ship something.

There are 18 freight classes, ranging from Class 50 (cheapest) to Class 500 (most expensive). Your shipment’s class is based on four things:

1. Density – How heavy it is compared to its size. (Heavier = lower class = cheaper!)

2. Stowability – How easily it can be stored with other freight.

3. Handling – Is it fragile, hazardous, or difficult to move?

4. Liability – Is it valuable or prone to damage or theft?

👉 Example: A heavy box of car parts might be Class 55, while a lightweight but bulky sofa might be Class 250.

⚖️ Understanding Freight Weight

Weight matters — a lot — when determining shipping rates. But it’s not just about how heavy your cargo is. Here’s what you need to know:

• Actual Weight: The scale weight of your shipment.

• Dimensional (DIM) Weight: Used when a package takes up more space than its weight suggests (common in air freight or bulky items).

Pro Tip: Always measure your freight accurately — length x width x height — and include packaging or pallets in your weight estimates. Underestimating can lead to surprise charges later.

💰 So… How Are Freight Rates Calculated?

Rates depend on a mix of variables, including:

• Freight class

• Weight and dimensions

• Distance traveled

• Mode of transport (LTL, FTL, expedited, etc.)

• Fuel costs and current market demand

At Seashore, we use real-time quoting tools and transparent rate breakdowns so you’re never in the dark. No fine print. No inflated surprises. Just the best rate we can offer — clearly explained.

🛣️ LTL vs. FTL — Quick Breakdown

• LTL (Less-than-Truckload): You’re sharing space with other shippers. Best for smaller shipments.

• FTL (Full Truckload): You get the whole truck. Ideal for large shipments or those on a tight schedule.
