Freight Class and Accessorials: What Actually Sets the LTL Bill on Wholesale Orders

Parcel pricing is mostly a function of weight, dimensions and zone. Less-than-truckload freight is not. When a wholesale order leaves as pallets instead of boxes, the invoice is built from a different set of inputs — freight classification, the accessorial services the delivery actually required, and whatever the carrier measured when the pallet crossed its dock. Sellers who are new to B2B volume usually discover this through a rebill weeks after the shipment delivered.

Here is what each of those inputs is, and what you can control from the warehouse side.

Freight class, and why density decides most of it

LTL carriers classify commodities using the National Motor Freight Classification. A classification reflects four characteristics: density, stowability, handling and liability. In practice, for most consumer goods moving on pallets, density does the heavy lifting — and the NMFTA has been steadily moving commodity listings onto density-based scales, which makes getting your dimensions right more consequential than it used to be.

Density is straightforward arithmetic: total weight divided by total cubic feet, measured over the whole pallet including the pallet itself and any overhang. A 48×40×60-inch pallet is 66.7 cubic feet; at 800 lb that is 12 lb per cubic foot.

Lower class means a lower rate per hundredweight. The table is abbreviated and density alone does not settle every commodity, so treat it as a way to understand your exposure rather than as a rate sheet.

Two things follow. First, air inside the carton is expensive on LTL just as it is on parcel. Second, how the pallet is built changes the class — the same units stacked to 72 inches with a void in the middle can land a tier higher than the same units stacked tight to 54 inches.

Reweighs and reclassification

Carriers run pallets through dimensioners and scales at the terminal. If what they measure does not match the bill of lading, they correct it and rebill. That correction can move the class, the weight, or both, and it often arrives with an inspection fee attached.

The defenses are unglamorous:

• Weigh and measure the finished pallet, not the theoretical one from the order.
• Record the height actually achieved after wrapping, including anything protruding.
• Note overhang. A carton hanging past the pallet edge changes the footprint the carrier measures and invites damage claims.
• Keep the measurement record with the shipment so a dispute has something behind it.

The warehouse-side mechanics of getting from a purchase order to a wrapped, measured pallet are covered in how B2B orders move through the warehouse.

Accessorials: the charges nobody quoted

Accessorials are services beyond dock-to-dock movement. They are legitimate, they are usually avoidable with information, and they are the single most common source of "why is this invoice higher than the quote".

• Liftgate at delivery — required whenever the consignee has no dock. Common for small retail storefronts, gyms, salons, and anything shipping to a business that operates out of a unit rather than a warehouse.
• Residential delivery — applies by the character of the address, not by who is receiving. A home-based business counts.
• Limited access — schools, military bases, construction sites, self-storage, farms, places where the driver cannot simply back in.
• Inside delivery — moving freight past the threshold.
• Appointment / notify before delivery — required by most retail distribution centers, and separately billed by most carriers.
• Redelivery — the charge for a second attempt after a missed appointment.
• Detention — waiting time at either end beyond the free window.

None of these can be decided by the warehouse. They are properties of the destination, and they have to come in with the order. If your order intake does not have fields for "dock or no dock" and "appointment required", the information will not exist when the bill of lading is created — and the carrier will add the service at its own rate.

The bill of lading is the contract

Most LTL disputes come down to what the BOL said. It should carry accurate piece count and packaging type, accurate weight, the commodity description and class, the correct accessorial flags, and any special instructions the consignee's routing guide demands. Retail destinations add their own layer of requirements on top; a missed field there produces a chargeback in addition to a freight correction.

For shipments going to many destinations off one inbound, the way you stage and consolidate matters as much as the paperwork — see moving pallet volume to many destinations.

A short checklist before the pallet ships

1. Finished pallet weighed and measured, wrapped, with dimensions recorded.
2. Density calculated from those numbers, and class taken from the density rather than from memory.
3. Destination profile confirmed: dock, residential, limited access, appointment.
4. Accessorials declared on the BOL before pickup, not discovered at delivery.
5. Piece count and packaging type matching what is physically on the trailer.
6. A photo of the wrapped pallet retained.

None of this makes freight cheap. It makes the invoice predictable, which for a wholesale program that quotes delivered pricing is the part that actually matters. Our B2B fulfillment page covers how these steps sit inside the wider order flow.
