If you've ever needed to move a pallet of goods, a piece of machinery, or a truckload of raw materials, you've run into the question: what is freight shipping, and how does it actually work?
Freight shipping is the backbone of commerce. Every product on a store shelf, every piece of equipment on a job site, and every raw material in a factory arrived there through some form of freight transport. Yet for businesses that don't move freight every day, the terminology, pricing, and logistics can be confusing.
This guide covers everything you need to know — from the basics of what freight shipping is to how to choose a provider that actually delivers.
What Is Freight Shipping?
Freight shipping is the transportation of large quantities of goods — pallets, crates, machinery, raw materials — by truck, rail, air, or sea. Unlike parcel shipping (which handles small packages like what the post office delivers), freight shipping moves bulk goods that don't fit standard shipping dimensions or weight limits.
If your shipment:
- Weighs more than 150 pounds
- Won't fit on a standard pallet
- Requires specialized handling (refrigeration, oversize, hazmat)
- Fills an entire truck or shipping container
— you're dealing with freight shipping, not parcel shipping.
Freight is most commonly moved by truck in the United States, which is why companies like SeaSound Transport focus on overland freight hauling across Washington and the Pacific Northwest. But the principles apply whether your shipment goes by truck, train, ship, or plane.
Types of Freight Shipping
Not all freight is moved the same way. The right method depends on your shipment size, timeline, and budget.
Full Truckload (FTL)
FTL means your shipment occupies an entire trailer. It's most cost-effective when you have enough freight — typically more than 10 pallets or 15,000 pounds — to fill the truck. The truck goes directly from pickup to delivery without intermediate stops.
Best for: Large shipments, high-value goods, direct routes.
Less-than-Truckload (LTL)
LTL means your shipment shares trailer space with other customers' freight. You pay only for the space your goods occupy. LTL networks involve hub-and-spoke systems where freight is sorted and reloaded at terminals along the route.
Best for: Shipments between 1 and 10 pallets, regional distribution, cost-conscious shipping.
Intermodal
Intermodal shipping combines truck and rail (or truck and ship). The container moves by rail for the long-haul portion and by truck for first- and last-mile delivery. Intermodal is often cheaper than over-the-road trucking for long distances, though transit times are longer.
Best for: Cross-country shipping, lower-cost long-distance moves, freight that isn't time-sensitive.
Expedited Freight
Expedited shipping prioritizes speed. This typically means a dedicated truck with a single driver running directly to the destination, or team drivers who keep the truck moving around the clock.
Best for: Emergency shipments, production line stops, time-sensitive materials.
Specialized Freight
Some freight needs specialized equipment: refrigerated trailers (reefers) for perishables, flatbeds for oversized loads, tankers for liquids, and hazmat-certified trucks for dangerous goods.
Best for: Temperature-controlled goods, construction materials, chemicals, and equipment.
How Freight Shipping Works (Step by Step)
If you're new to freight, here's the typical process from start to finish.
Step 1: Get a Quote
You provide pickup and delivery locations, shipment weight and dimensions, freight class (for LTL), and any special handling requirements. The carrier or broker provides a rate based on these factors.
Step 2: Schedule the Pickup
Once you accept the quote, the carrier schedules a pickup window. For FTL, this is usually a specific day. For LTL, it may be a window of several hours while the driver works a route.
Step 3: Prepare Your Freight
Freight should be palletized, shrink-wrapped, labeled, and secured. Proper preparation prevents damage during transit and ensures your freight moves through the system efficiently.
Step 4: Pickup and Transit
The carrier picks up your freight and transports it to the destination. FTL loads go direct. LTL loads route through terminals. Tracking is available for most shipments.
Step 5: Delivery and Proof of Delivery
The freight arrives at the destination. The receiver inspects it and signs the bill of lading (BOL), which serves as proof of delivery and a receipt.
Freight Shipping Costs: What Drives the Price
Freight pricing can seem opaque, but it follows a few key variables.
Weight and Dimensions
Heavier and larger shipments cost more. Freight carriers use dimensional weight (DIM) pricing, which means a lightweight but bulky shipment can cost as much as a heavy, compact one.
Distance
Longer distances mean higher fuel costs, more driver hours, and more wear on equipment. Local moves (under 100 miles) are priced per hour or per stop. Regional and long-haul moves are priced per mile.
Freight Class (LTL)
LTL pricing uses a classification system (National Motor Freight Classification, or NMFC) based on density, handling, stowability, and liability. Class 50 (dense, easy to handle) is cheapest. Class 500 (fragile, bulky, hard to handle) is most expensive.
Accessorial Fees
These add-ons cover extra services: liftgate delivery, inside pickup, residential delivery, appointment scheduling, detention time, and re-delivery. Accessorial fees often surprise first-time shippers, so ask about them upfront.
Fuel Surcharges
Most carriers adjust rates based on fuel prices. The surcharge floats with national or regional fuel indices.
Market Conditions
Freight rates fluctuate with supply and demand. Peak seasons (Q4 holiday retail) drive rates up. Slow periods (January) may offer lower rates.
Freight Shipping vs. Parcel Shipping
| Factor | Parcel | Freight | |--------|--------|---------| | Max weight | ~150 lbs | Unlimited | | Typical size | Small boxes | Pallets, crates, machinery | | Carrier | UPS, FedEx, USPS | Trucking companies, freight carriers | | Pricing | Zone + weight | Density, class, distance, accessorials | | Tracking | Package-level | Shipment-level | | Transit time | 1-5 days | Same day to 7+ days |
If your shipment exceeds parcel limits, or if you're moving freight regularly, partnering with a dedicated freight provider like SeaSound Transport gives you better pricing, more reliability, and a relationship that parcel carriers can't match.
How to Choose a Freight Shipping Provider
Choosing the right provider matters more than most businesses realize. A wrong choice means late deliveries, damaged goods, and unexpected fees.
What to Look For
Local knowledge. A carrier that knows the roads, warehouses, and delivery requirements of your area will outperform one that doesn't. In Washington, that means understanding the I-5 corridor, the 167 bottleneck, Seattle's downtown delivery zones, and how weather affects transit times.
Reliable equipment. A well-maintained fleet breaks down less often. Ask about maintenance schedules, average fleet age, and contingency plans.
Transparent pricing. The best carriers quote all-in pricing and explain what accessorial fees might apply before you book, not after.
Communication. Can you reach a real person when something goes wrong? Do they provide tracking? Do they proactively communicate delays?
Red Flags
- Prices that seem too good to be true (they usually are)
- Refusal to provide references or proof of insurance
- No clear process for handling damage claims
- Vague answers about transit times

FAQ
What is freight shipping?
Freight shipping is the transportation of large quantities of goods — pallets, crates, machinery, raw materials — by truck, rail, air, or sea. Unlike parcel shipping (which handles small packages), freight shipping moves bulk goods that don't fit standard shipping dimensions or weight limits.
What are the different types of freight shipping?
The main types are Full Truckload (FTL) for large shipments that fill a trailer, Less-than-Truckload (LTL) for smaller shipments that share trailer space, intermodal for combining truck and rail transport, expedited for time-sensitive deliveries, and specialized freight for oversized, refrigerated, or hazardous materials.
How much does freight shipping cost?
Freight shipping costs depend on weight, dimensions, distance, fuel surcharges, accessorial fees, and market demand. LTL shipments typically range from $100 to $500 for regional moves. FTL loads cost $500 to $2,000+. The best way to get an accurate price is to provide complete shipment details to a provider who can quote based on real-time rates.
How long does freight shipping take?
Local freight (under 100 miles) can arrive same-day or next-day. Regional shipping (100-500 miles) typically takes 1-3 days. Cross-country shipping takes 3-7 days by truck. Expedited services can reduce these timelines significantly.
What's the difference between freight shipping and parcel shipping?
Parcel shipping handles packages under 150 pounds through carriers like UPS and FedEx. Freight shipping handles anything too large or heavy for parcel — typically palletized goods, industrial equipment, and bulk materials that require a truck, railcar, or shipping container.
Do I need a freight broker or a freight carrier?
A freight broker connects you with carriers and handles logistics — useful if you ship infrequently. A freight carrier owns the trucks and does the actual hauling. Use a broker if you need guidance; go direct to a carrier if you ship regularly and want a consistent relationship.
