Freight is the commercial transport of goods, raw materials, components, or finished products, in bulk or pallet quantities by truck, rail, ocean vessel, or aircraft. Unlike parcel shipping (individual packages sent via FedEx, UPS, or USPS), freight shipments are typically 150 lbs or more, require a Bill of Lading, and are priced based on weight, freight class, lane, and transportation mode. Freight is the physical engine of global commerce, moving approximately $18 trillion in goods annually across domestic and international supply chains.
The word "freight" derives from the Middle Dutch "vrecht", meaning the hire of a ship and has been used in commercial transport contexts for centuries. In modern logistics, freight encompasses any shipment that exceeds the size, weight, or handling requirements of standard parcel carriers. If it moves on a pallet, in a shipping container, or in a truckload — it's freight.
Freight is not simply "shipping writ large." It is a distinct discipline with its own pricing structures, regulatory frameworks, documentation requirements, carrier networks, and professional expertise. Understanding how freight works is essential for any business that buys, makes, or sells physical goods because freight costs, service levels, and reliability directly determine your supply chain's competitiveness and your customers' experience.
One of the most common points of confusion in logistics is where parcel shipping ends and freight begins. The distinction matters enormously for cost management, shipping a 200-lb pallet as a FedEx package would cost 5–10x more than shipping it as freight, while misrouting a small parcel through freight carriers adds unnecessary complexity and cost in the other direction.
The Crossover Point: The general rule of thumb: if your shipment is more than 150 lbs or requires a pallet, freight carriers will almost always deliver better economics than parcel carriers. At 50–150 lbs, you should get quotes from both and compare, the crossover point varies by lane, dimensional weight, and carrier surcharge structures. At under 50 lbs, parcel almost always wins on both cost and convenience.
Every freight shipment must choose one or more transportation modes, each with distinct cost, speed, capacity, and environmental characteristics. Mode selection is one of the most impactful freight decisions a shipper makes, directly determining total cost and transit time.
Handles 70%+ of U.S. freight by value. Most flexible mode reaches any road-accessible location. Best for: domestic shipments under 2,500 miles, time-sensitive loads, door-to-door service. Service types: LTL, FTL, partial, expedited, specialized.
Most cost-efficient for heavy, bulk commodities (coal, grain, chemicals, autos) over 1,000+ miles. Rail intermodal, containers moving by both train and truck, is growing rapidly for consumer goods on transcontinental lanes. It uses 3 to 5 times lower fuel consumption per ton-mile than trucking.
Carries approximately 90% of world trade by volume. Cheapest per unit over long distances, but slowest typically 14–45 days port-to-port. Available in FCL (Full Container Load) and LCL (Less than Container Load). Critical for Asia–North America and Trans-Atlantic trade lanes.
4–10x the cost of ocean freight per kg but delivers in 1–5 days globally. Used for high-value goods (electronics, pharmaceuticals, jewelry), perishables, time-critical emergency supply chain replenishment, and fashion/seasonal goods where speed-to-market justifies the premium.
Combines rail and truck — freight loaded into a container at origin, trucked to a rail ramp, transported by train, then trucked to final delivery. Typically 10–20% cheaper than over-the-road trucking on lanes over 1,500 miles, with 1–3 extra days of transit time.
Uses multiple transportation modes under a single contract, for example, truck to port, ocean crossing, then rail + truck to final destination. Common in international supply chains where goods cross multiple geographies and transportation systems before reaching the consignee.
LTL (less-than-truckload) is a freight shipping method where your shipment, typically 1 to 6 pallets or about 150 to 15,000 lbs, shares space in a trailer with freight from other shippers. You pay only for the space you use, based on freight class, weight, and lane.
LTL carriers operate hub-and-spoke terminal networks, meaning your freight is picked up locally, sorted at a regional terminal, consolidated with other freight heading the same direction, and forwarded to destination. Transit: 2–5 days typical. For a deep comparison of LTL and FTL, see Buske's LTL vs. FTL guide.
FTL dedicates an entire 48 or 53-foot trailer exclusively to one shipper's freight. You pay for the full trailer regardless of whether you completely fill it. In exchange, your freight travels direct from origin to destination without terminal stops, achieving faster transit (1–3 days), lower damage risk (freight is loaded once and not touched again until delivery), and complete load security. Best for: 15,000+ lbs, 7+ pallets, fragile or high-value goods, and time-critical shipments.
PTL (partial truckload) sits between LTL and FTL for mid-sized shipments, typically 6 to 18 pallets. It is used when a shipment is too large for LTL pricing to be efficient but not large enough to justify a full truckload. PTL offers fewer handling touches than LTL (reducing damage risk), no freight class complexity, and often better economics for the volume range. It is becoming increasingly available as carriers build out their PTL service networks.
Expedited freight services guarantee delivery within defined time windows, sometimes within hours, using team drivers to avoid mandatory rest period delays or dedicated straight trucks for nonstop transit. Used for production line emergencies, critical medical supply replenishment, time-sensitive e-commerce fulfillment, and other scenarios where the cost of delay exceeds the premium for speed. Expedited rates typically run 50–150% above standard freight rates.
Open deck flatbed trailers handle oversized, heavy, or irregularly shaped freight that cannot fit inside an enclosed trailer, such as steel coils, lumber, construction equipment, industrial machinery, and prefabricated building components. Specialized equipment includes step-deck (lower deck height for taller loads), RGN (removable gooseneck for the heaviest equipment), and double-drop (for very tall, heavy loads). Flatbed loads typically require tarping, chains, or straps per DOT regulations.
Temperature controlled trailers maintain specified temperature ranges, from 34 to 40°F for fresh produce to -10°F for frozen goods, throughout the transit journey. Reefer freight serves food & beverage, pharmaceutical, beauty, and chemical industries. Reefer rates command a 15–30% premium over dry van due to fuel costs (refrigeration units run continuously), equipment maintenance, and higher driver qualification requirements. Cold chain integrity is regulated by FDA's FSMA Rule for Sanitary Transportation of Human and Animal Food.
Freight pricing is notoriously complex and that complexity is the single most common source of unexpected invoice charges for shippers who don't fully understand what drives their rates. Here is a complete breakdown of every cost component.
For LTL, base rates are derived from carrier tariffs, published rate tables that define the cost per hundredweight (CWT, i.e., per 100 lbs) for a given freight class and origin-destination lane. FTL base rates are negotiated per lane (typically as a per-mile rate) based on distance, equipment type, and carrier capacity availability in that corridor.
Fuel surcharges are added to base rates as a percentage, indexed to weekly diesel fuel prices published by the U.S. Energy Information Administration (EIA). Fuel surcharges typically represent 20–30% of the total freight invoice, a significant and often overlooked cost component when comparing quotes. Always request the all-in rate including fuel surcharge, not just the base rate.
Accessorial charges are add-on fees for services or conditions beyond standard pickup and delivery. Common accessorials include:
For LTL freight, carriers may calculate a dimensional weight (L × W × H in inches ÷ 139 for domestic US) and charge whichever is greater, actual weight or DIM weight. Low-density, bulky freight often triggers DIM weight pricing, which is why accurate dimensional measurement is critical for LTL quote accuracy.
LTL carriers weigh and measure shipments at origin terminals. If your declared weight or freight class differs from what the carrier's scales and inspection find, you will receive an invoice adjustment often called a "weight and inspection" (W&I) charge. These adjustments can add 10–30% to the original quote. Accuracy in initial weight and class declaration is the most effective way to avoid surprises.
Cost Reduction Strategy
Businesses that work with a 3PL like Buske Logistics benefit from pre-negotiated contract rates that are typically 10–30% below what individual shippers can access directly from carriers. Volume aggregation across multiple clients gives 3PLs the purchasing leverage to secure rates that are structurally unavailable to individual shippers regardless of their own volume. For most mid-market businesses, the 3PL rate advantage alone more than offsets any management fee.
Freight class is the LTL pricing backbone — a standardized commodity classification system maintained by the National Motor Freight Traffic Association (NMFTA) through the National Motor Freight Classification (NMFC). There are 18 freight classes: 50, 55, 65, 70, 77.5, 85, 92.5, 100, 110, 125, 150, 175, 200, 250, 300, 400, and 500.
Every commodity that ships via LTL has an NMFC item number and a corresponding class. Lower class numbers mean denser, easier-to-handle, lower-liability freight and lower rates. Higher class numbers mean low-density, difficult, or high-liability freight and higher rates.
Density-Based Pricing (DBP)
Many LTL carriers now offer density based pricing as an alternative to NMFC class, calculating pounds per cubic foot from your declared dimensions and weight to determine rates without using NMFC item numbers. This approach eliminates class disputes and reclass charges while making pricing more predictable for shippers. It often improves economics for dense commodities, so it is worth asking your 3PL or carrier if density based pricing is available for your freight.
Every freight shipment requires a specific set of documentation. Missing or incorrect paperwork is one of the most common causes of freight delays, accessorial charges, and claims disputes. Here are the documents every shipper must understand.
The Bill of Lading is the most important document in freight shipping, a legally binding contract between the shipper and carrier that serves three simultaneous functions: a shipping contract (defining the terms of carriage), a receipt (confirming the carrier has taken possession of the described freight in the stated condition), and a document of title (for negotiable BOLs, establishing legal ownership during transit).
A BOL must accurately state: shipper and consignee names and addresses, freight description and NMFC item number, weight, number of pieces and packaging type, freight class, declared value, and any special handling instructions. Never release freight to a carrier without a completed, signed BOL. BOL errors are the most common cause of re-class charges, delivery delays, and claims disputes.
The POD is a document signed by the consignee at the time of delivery confirming that they received the freight in the described quantity and condition. PODs are essential for resolving claims — if the consignee notes exceptions (damaged packaging, short count, visible damage) on the POD at time of delivery, those notations become critical evidence in a freight claim. Always retain PODs. For freight claims, carriers require a POD as part of the claims package.
The carrier's charge to the shipper. Freight invoices should be audited against the original rate quote before payment. Discrepancies (undisclosed accessorials, re-weigh charges, fuel surcharge miscalculations) are common and can add 5–20% above the quoted rate. Many 3PLs offer freight audit services as part of their TMS capabilities, systematically catching invoice errors before payment.
For international freight, a commercial invoice is required by customs authorities, declaring the shipment’s value, country of origin, Harmonized System (HS) tariff codes for each product, and the terms of sale (Incoterms). The commercial invoice determines import duties and taxes, so accuracy is not just procedural; errors can result in customs holds, duty overpayments, or compliance penalties.
An itemized list of the shipment’s contents, including quantities, weights, dimensions, and descriptions at the package or pallet level. The packing list accompanies the BOL and is used by the carrier for load planning and by the consignee for receiving verification.
Getting accurate, competitive freight quotes requires providing precise shipment information and knowing where to look. Here is the step-by-step process:
The 3PL Advantage on Freight
Buske Logistics manages freight on behalf of clients across North American lanes leveraging aggregated volume to secure contract rates with major carriers that individual shippers cannot access regardless of their own volume. Our TMS technology handles carrier selection, rate comparison, booking, tracking, and freight audit automatically turning what is typically a labor-intensive procurement process into a single click. See our complete Freight Shipping 101 guide and LTL vs. FTL decision guide for more.
International freight introduces layers of complexity beyond domestic shipping: customs clearance, import duties and tariffs, country-of-origin documentation, export controls, foreign trade regulations, and the coordination of multiple transportation modes across geographic boundaries.
Ocean freight offers the same fundamental LTL and FTL dynamic as domestic trucking, expressed in container terms. Full container load (FCL) dedicates a full 20 foot or 40 foot container to a single shipper, with typical transit of 14 to 45 days, direct loading at origin, lower per unit cost at high volumes, and lower damage risk. Less than container load (LCL) consolidates multiple shippers’ cargo in a single container, offering better economics for smaller volumes but adding consolidation and deconsolidation time along with some increased handling risk.
Incoterms (International Commercial Terms), published by the International Chamber of Commerce (ICC), define the division of cost and risk between buyer and seller in international transactions. The most important Incoterms for freight shippers are EXW (Ex Works, buyer assumes all responsibility from the seller's facility), FOB (Free On Board, seller is responsible until goods are on the vessel at port of origin), CIF (Cost, Insurance and Freight, seller pays ocean freight and insurance to destination port), and DDP (Delivered Duty Paid, seller is responsible for everything including import duties at destination).
Getting Incoterms wrong is one of the most expensive mistakes in international trade because it determines who files insurance claims and who absorbs shipping cost increases.
Every international shipment crossing a border requires customs clearance; the process of presenting documentation to customs authorities, having the shipment assessed for applicable duties and taxes, and receiving clearance to import or export.
Working with a licensed customs broker eliminates the risk of costly clearance delays from documentation errors or HS code misclassification. Many 3PLs integrate customs brokerage into their international freight services, providing single-point accountability for the end-to-end international freight journey.
“Shipping” is a broad term for moving goods from one place to another. “Freight” refers specifically to large commercial shipments, typically 150 lbs or more and often palletized, which are transported by dedicated carriers using trucks, trains, ships, or aircraft. Parcel shipping (FedEx, UPS, USPS) handles smaller individual packages. Freight handles bulk commercial volumes. The key distinctions are scale, pricing mechanisms (freight class vs. zone/weight), documentation (BOL vs. shipping label), and the specialized carrier networks involved.
Freight is categorized by transportation mode, including road or trucking, rail, ocean, air, and intermodal, as well as by service type. The main service types include LTL (Less-Than-Truckload), which shares trailer space for smaller shipments; FTL (Full Truckload), which uses a dedicated trailer for a single shipper; PTL (Partial Truckload) for mid-sized shipments; expedited services that provide time-definite delivery; flatbed or specialized transport for oversized or irregular cargo; and refrigerated (reefer) shipping for temperature-sensitive goods such as perishables and pharmaceuticals.
Freight cost is calculated from several components: (1) Base rate — for LTL, derived from freight class, weight, and lane; for FTL, negotiated per-mile rate for the specific lane; (2) Fuel surcharge — typically 20–30% added to the base rate, indexed to weekly diesel prices; (3) Accessorial charges — add-on fees for liftgate, residential delivery, limited access, inside delivery, detention, and other non-standard conditions; (4) Dimensional weight — for bulky, low-density freight, carriers may charge based on volume rather than actual weight. The total invoice is the sum of all these components, which is why all-in quotes are essential for accurate cost comparison.
A Bill of Lading (BOL) is the legal contract between a shipper and carrier for a freight shipment. It simultaneously serves as a shipping contract (defining terms of carriage), a receipt (acknowledging the carrier has taken possession of the freight), and a document of title (establishing ownership). The BOL is required because it protects both parties legally, provides customs documentation for international shipments, enables freight claims when damage or shortage occurs, and is used by carriers for load planning and delivery verification. Errors on the BOL, such as incorrect weight, freight class, or address, are among the most common causes of invoice adjustments, delivery delays, and claims complications.
Freight class is the LTL pricing classification assigned to a commodity by the National Motor Freight Classification (NMFC) system, ranging from Class 50 (densest, cheapest) to Class 500 (lightest, most expensive). Class is determined by four factors: density (lbs per cubic foot), stow-ability, handling difficulty, and liability. To find your freight class, look up your product’s NMFC item number at nmfta.org, use a freight class calculator (most carrier and TMS platforms provide one), or consult your 3PL or freight broker. Misclassification can lead to reclassification charges that may add 10 to 30 percent to your invoice.
Intermodal freight combines two or more transportation modes under a single shipment, most commonly truck and rail. A container is trucked to a rail terminal (ramp), transported by train to a destination ramp, then trucked to final delivery. Use intermodal when: your shipment is over 1,500 miles (where rail economics are most favorable), you can accept 1–3 additional transit days versus over-the-road trucking, and your freight is not time-critical. Intermodal typically saves 10–20% versus comparable FTL rates on qualifying long-haul lanes, while also reducing carbon emissions by approximately 75% versus all-truck movement.
FCL (Full Container Load) refers to a shipment where an entire shipping container is dedicated to a single shipper’s cargo, typically in 20-foot (TEU) or 40-foot (FEU) containers. LCL (Less than Container Load) consolidates multiple shippers' cargo in a single container. FCL is more cost-effective at higher volumes, offers lower damage risk (cargo is not handled during consolidation/deconsolidation), and typically achieves faster port-to-door transit. LCL works better for smaller volumes where a full container is not needed, accepting higher per-unit handling and some additional transit time for consolidation. The LCL/FCL breakeven point is typically around 15–20 cubic meters, depending on the lane and commodity.
Key strategies to reduce freight costs: (1) Work with a 3PL or freight broker to access pre-negotiated contract rates (10–30% below direct carrier rates); (2) Consolidate smaller LTL shipments into larger FTL or PTL loads where economics favor it; (3) Optimize packaging to reduce dimensional weight — eliminating air from packages lowers your DIM weight and rate; (4) Verify freight class accuracy before shipping to avoid re-class charges; (5) Audit freight invoices against quotes — invoice errors are common and recoverable; (6) Consider intermodal for long-haul lanes where transit time flexibility exists; (7) Build carrier rate benchmarks using TMS analytics to ensure you are not drifting above market rates over time.
