LTL (Less Than Truckload) Shipping: Complete Guide
Less Than Truckload (LTL) shipping is the dominant freight transportation method for businesses shipping palletized goods that don't fill an entire truck. Understanding how LTL works—including its hub-and-spoke distribution network, freight class system, accessorial charges, and service options—is essential for controlling freight costs and ensuring reliable delivery of your products.
What Is LTL (Less Than Truckload) Freight Shipping?
LTL shipping allows multiple shippers to share space on the same truck, each paying only for the portion of the trailer their freight occupies. This shared-space model makes LTL the most cost-effective shipping method for businesses regularly moving substantial quantities of goods that don't fill a complete trailer (typically 150 lbs to 15,000 lbs per shipment).
The Hub-and-Spoke Distribution Model
LTL carriers operate using a hub-and-spoke distribution model, where freight moves from local terminals (spokes) to central sorting facilities (hubs) and back out to destination terminals for final delivery. This system allows carriers to maximize efficiency by consolidating freight from multiple origins at regional hubs, sorting it by destination, and dispatching it along optimized routes.
For example, a shipment traveling from Portland, Oregon to Charlotte, North Carolina might pass through terminals in Sacramento, Salt Lake City, and Memphis before reaching Charlotte—with each hub serving as a strategic sorting point. While this model reduces transportation costs by maximizing trailer utilization, the tradeoff is longer transit times and increased handling compared to direct Full Truckload shipping.
Final Delivery Process
When freight arrives at the destination terminal, it's sorted onto local delivery trucks based on geographic routes. Recipients should monitor tracking updates as the shipment approaches the destination terminal. Basic dock-to-dock delivery is included in standard LTL rates, assuming the receiving location has a commercial loading dock and appropriate equipment.
| Service Type | Description | Typical Additional Cost | Requirements |
|---|---|---|---|
| Dock Delivery | Standard delivery to commercial dock | Included in base rate | Loading dock and forklift required |
| Liftgate Service | Hydraulic platform lowers freight to ground | $75–$150 per shipment | For locations without loading dock |
| Inside Delivery | Driver brings freight inside building | $100–$250 per shipment | Advance notice required |
| Residential Delivery | Delivery to home address | $75–$175 per shipment | Limited access, longer windows |
| Appointment Delivery | Guaranteed delivery window | $50–$125 per shipment | 2–4 hour windows typical |
| Delivery Notification | Advance call before delivery | $25–$50 per shipment | 1–2 hour notice before arrival |
LTL Shipment Requirements
LTL is designed for freight that doesn't require a full truck trailer, typically weighing between 150 and 15,000 pounds. Understanding and adhering to carrier requirements is crucial for avoiding delays, reclassification charges, and potential freight rejection.
Weight and Size Guidelines
| Measurement Type | Typical Limit | Notes |
|---|---|---|
| Minimum Weight | 150–200 lbs | Below this may incur minimum charges |
| Maximum Weight per Shipment | 10,000–20,000 lbs | Varies by carrier |
| Maximum Weight per Piece | 2,500 lbs | Handling equipment limitation |
| Maximum Length | 8–12 feet | Per piece |
| Maximum Width | 48–53 inches | Standard pallet width |
| Maximum Height | 96–108 inches | Including pallet |
| Maximum Linear Feet | 12–16 feet | Total floor space occupied |
Palletizing Standards
Proper palletizing is essential for LTL shipments to prevent damage during the multiple handling points characteristic of consolidated freight. The industry standard pallet size is 48" x 40" (GMA pallet). Your freight must be secured using stretch wrap (minimum 3–5 layers), strapping for heavier items, or both.
| Pallet Type | Dimensions (Imperial) | Weight Capacity | Best For |
|---|---|---|---|
| GMA/Standard | 48" × 40" | 4,600 lbs | Most LTL freight |
| Euro Pallet | 48" × 42" | 4,400 lbs | International shipments |
| Half Pallet | 48" × 20" | 2,800 lbs | Smaller shipments |
| Block Pallet | 48" × 48" | 5,500 lbs | Heavy machinery |
Freight Class Classification (NMFC)
Freight class directly impacts your shipping costs. Classes range from 50 to 500, determined by density (weight per cubic foot), stowability, handling, and liability.
Density Calculation: Weight (lbs) ÷ [Length (in) × Width (in) × Height (in) ÷ 1,728] = Density per cubic foot
| Class | Density (lbs/cu ft) | Typical Examples | Cost Level |
|---|---|---|---|
| 50 | 50+ | Steel, bricks, cement | Lowest |
| 70 | 15–22.5 | Food items, automobile parts | Average |
| 100 | 9–10.5 | Boat covers, canvas | Higher |
| 150 | 6–7 | Auto sheet metal parts, bookcases | Very High |
| 200 | 4–5 | Aircraft parts, aluminum table | Expensive |
| 300 | 2–3 | Wood cabinets, tables, chairs | Premium |
| 500 | <1 | Ping pong balls, bags of gold dust | Highest |
Benefits of LTL Shipping
- Cost savings vs. FTL: Pay only for the space your freight occupies — typically 30 to 60 percent less than a full truckload for smaller shipments.
- No minimum volume: Ship as little as 150 pounds through established carrier networks without volume commitments.
- Extensive coverage: National and regional carriers provide near-universal coverage across the continental US, with most areas accessible within 1 to 5 business days.
- Flexible service options: Liftgate, residential, inside delivery, appointment windows, and hazmat handling available as accessorials.
- Tracking and visibility: All major LTL carriers provide real-time tracking by Pro number (bill of lading number) or electronic notification systems.
- Reduced environmental impact: Sharing trailer space across multiple shippers reduces total truck movements and carbon emissions per pound of freight shipped.
Cost Reduction Strategies for LTL Shipping
- Accurately classify freight: Correct freight class at booking prevents expensive reclassification charges at the terminal.
- Optimize packaging density: Denser loads receive lower freight classes. Reduce void fill and excessive packaging to improve density.
- Use commercial addresses: Avoid $75 to $175 residential delivery surcharges by coordinating delivery to commercial locations when possible.
- Compare multiple carriers: Rate differences of 20 to 40 percent between carriers for the same lane are common. Use freight brokers to access pre-negotiated rates.
- Consolidate shipments: Combining multiple smaller shipments into a single larger one typically reduces per-unit shipping costs significantly.
- Negotiate volume rates: Committed monthly shipping volumes unlock contract rates significantly below published tariffs from most major LTL carriers.
- Audit invoices regularly: LTL billing errors are common. Freight invoice auditing typically recovers 3 to 8 percent of total freight spend.
