Key Points at a Glance
- Parcel suits small packages; LTL suits palletized freight generally over about 150 pounds.
- LTL pricing depends on weight, distance, freight class, density, fuel surcharges, and accessorials.
- The 2025 NMFC overhaul made accurate dimensions and weights more important than ever.
- FOB terms determine who pays freight and who owns goods in transit.
- Note damage on the delivery receipt before signing, and report concealed damage promptly.
Freight is one of those costs that rarely gets attention until an invoice arrives with a number nobody expected. A transformer that shipped for one price last spring costs noticeably more this fall. A pallet of enclosures shows up with a liftgate fee, a limited-access fee, and a reclassification charge. A parcel shipment that should have been routine carries an “additional handling” surcharge.
For industrial buyers, a basic understanding of how freight is priced pays off quickly. This article explains the difference between parcel and LTL, how freight class and density work, what accessorial charges are, how FOB terms affect who pays and who owns the goods in transit, and what to do when something arrives damaged.
Parcel vs. LTL: Where the Line Falls
| Factor | Parcel | LTL (Less-Than-Truckload) |
| Typical size | Individual boxes | Palletized or crated freight |
| Typical weight | Up to about 150 lbs per package | Generally 150 lbs to several thousand lbs |
| Pricing basis | Weight, dimensions (dimensional weight), zone, service level | Weight, freight class, distance, accessorials |
| Handling | Automated sorting, conveyor systems | Forklifts and dock handling |
| Tracking | Detailed package-level tracking | Shipment-level tracking |
| Best for | Small components, control parts, sensors | Transformers, enclosures, wire reels, switchgear, bulk orders |
Parcel carriers publish size and weight limits, and packages near those limits often incur additional handling or oversize surcharges. ¹ When a shipment becomes several heavy boxes, consolidating them onto a pallet and shipping LTL is frequently cheaper and safer.
How LTL Pricing Works
LTL carriers combine freight from many shippers on the same trailer, so pricing reflects how much space and handling your shipment requires. The main factors are:
1. Weight and distance
Heavier shipments and longer distances cost more, though the rate per hundred pounds often decreases as weight increases.
2. Freight class
The National Motor Freight Classification (NMFC), maintained by the National Motor Freight Traffic Association (NMFTA), assigns commodities to classes ranging from 50 to 500. ² Lower classes generally mean lower rates per hundredweight. Class is based on four transportation characteristics:
- Density — weight per cubic foot
- Stowability — how easily the item fits with other freight
- Handling — special care required
- Liability — susceptibility to damage or theft, and value
3. Density is now more important than ever
In 2025, the NMFTA implemented a significant overhaul of the NMFC that shifted many commodities toward density-based classification. ³ In practice, that makes accurate dimensions and weights on the bill of lading more important than ever. Carriers routinely measure and weigh freight, and if your declared information does not match, the shipment may be reclassified and rebilled — often at a higher class.
Calculating density:
- Measure length, width, and height in inches, including the pallet.
- Multiply L × W × H and divide by 1,728 to get cubic feet.
- Divide total weight (including pallet) by cubic feet.
Example: A pallet measuring 48 × 40 × 50 inches weighing 600 lbs.
- 48 × 40 × 50 = 96,000 cubic inches ÷ 1,728 = 55.6 cubic feet
- 600 ÷ 55.6 ≈ 8 lbs per cubic foot
That density determines the class under density-based items. Packing tighter — less empty space, no oversized pallets — raises density and can lower class.
4. Fuel surcharges
Most carriers apply a fuel surcharge tied to the U.S. Energy Information Administration’s weekly diesel price index. ⁴ When diesel prices rise, freight costs rise with them, even when base rates do not change.
Accessorial Charges: The Line Items That Surprise People
Accessorials are fees for services beyond standard dock-to-dock pickup and delivery. Common examples:
| Accessorial | When It Applies |
| Liftgate (pickup or delivery) | No loading dock or forklift at the location |
| Residential delivery | Delivery to a home or home-based business |
| Limited-access location | Schools, construction sites, farms, military bases, churches, and similar sites |
| Inside delivery | Driver brings freight beyond the dock or entrance |
| Appointment / notify before delivery | Delivery requires a scheduled time or call ahead |
| Reclassification / reweigh | Declared class or weight does not match carrier inspection |
| Redelivery | First delivery attempt failed |
| Detention | Driver waits beyond allowed free time at pickup or delivery |
| Storage | Freight held at the terminal awaiting delivery |
Many of these are avoidable with accurate information at the time the shipment is booked. If your site requires a liftgate or appointment, say so up front. Adding an accessorial at booking is almost always cheaper than having it added after a failed delivery.
FOB Terms: Who Pays, and Who Owns It in Transit?
In domestic U.S. shipping, “FOB” (free on board) terms describe when ownership and risk transfer from seller to buyer, and are rooted in the Uniform Commercial Code. ⁵
| Term | Ownership Transfers | Freight Typically Paid By |
| FOB Origin, Freight Collect | At seller’s dock | Buyer |
| FOB Origin, Freight Prepaid | At seller’s dock | Seller (may be billed back) |
| FOB Origin, Prepaid and Add | At seller’s dock | Seller pays, adds to invoice |
| FOB Destination, Freight Prepaid | At buyer’s dock | Seller |
Why it matters: under FOB Origin, the buyer generally owns the goods while they are in transit — which affects who files a damage claim with the carrier. Read the terms on your quotes and invoices.
Receiving Freight: Protect Yourself at the Dock
The delivery receipt is your most important document if something goes wrong.
- Count pieces against the delivery receipt before the driver leaves.
- Inspect for visible damage — crushed corners, torn wrap, punctures, tip indicators, or wet packaging.
- Note any damage or shortage on the delivery receipt before signing. Be specific: “2 of 3 cartons crushed,” not just “damaged.”
- Photograph the freight and packaging.
- Inspect for concealed damage promptly, ideally the same day. Carriers often have short windows for reporting concealed damage.
- Keep packaging until the claim is resolved.
- Notify your supplier immediately so they can help with the claim and arrange a replacement.
Federal regulations set the framework for cargo loss and damage claims against motor carriers, including timelines for filing. ⁶ A clean signature on the delivery receipt makes a later claim much harder to win.
Seven Ways to Lower Freight Cost
- Consolidate orders so fewer shipments carry more product.
- Use local delivery or will-call when your supplier is nearby — no freight bill at all.
- Provide accurate dimensions and weights to avoid reclassification charges.
- Pack densely on properly sized pallets.
- Declare accessorials up front rather than after a failed delivery.
- Plan ahead so expedited service is the exception, not the routine.
- Review freight invoices for duplicate accessorials, incorrect weights, and fuel surcharge errors.
Key takeaway: Freight cost is driven by weight, distance, freight class, density, fuel, and accessorials. Accurate shipment information, consolidated orders, dense packing, and careful receiving keep costs predictable and protect you when something goes wrong.
Frequently Asked Questions
How can we find the right freight class for our shipment?
The NMFC assigns classes by commodity item number, and many items now depend on density. Your supplier or carrier can help identify the correct item and class, and the NMFTA provides classification tools for subscribers. Always measure and weigh accurately, including the pallet.
Why was our shipment reclassified?
Carriers inspect, measure, and weigh freight. If the actual density, dimensions, or commodity description differ from what was declared on the bill of lading, the carrier may reclassify the shipment and adjust the charges. Accurate information at booking prevents most reclassifications.
Who files a freight damage claim?
Generally, the party that owns the goods while they are in transit, which depends on the FOB terms. Under FOB Origin terms, that is usually the buyer; under FOB Destination, usually the seller. Your supplier can help with the claim process either way.
How long do we have to report concealed damage?
Carrier rules vary, and some allow only a short window — often a few days — to report concealed damage after delivery. Inspect shipments promptly, report issues immediately, and keep all packaging until the claim is settled.
Is it cheaper to ship multiple boxes or one pallet?
For several heavy boxes going to the same location, consolidating them on one pallet and shipping LTL is often cheaper and reduces the risk of a box going missing. For a few light boxes, parcel is usually more economical. Ask for both options when you are unsure.
What does “freight prepaid and add” mean on an invoice?
It means the seller arranged and paid the carrier, then added the freight charge to your invoice. Ownership typically transfers at the seller’s dock under FOB Origin terms, even though the seller handled the shipping.
