How to Read a Bill of Lading (BOL): A Field-by-Field Guide

The bill of lading (BOL) is the most important document in a freight shipment. It's the contract of carriage, the receipt for the goods, and the document of title all at once. It also drives how your shipment is rated — so the details matter.

The parties

• Shipper (consignor) — who the freight is coming from.
• Consignee — who it's going to.
• Bill-to / third party — who pays. This determines the freight terms (prepaid vs. collect).

The fields that drive your rate

These are the ones carriers use to price — and inspect — the shipment:

• Piece count and packaging type — e.g., "2 pallets," "5 crates." Miscounts cause disputes.
• Weight — total shipment weight. Carriers reweigh; overstating or understating triggers adjustments.
• Dimensions — increasingly required, because carriers rate on density. Measure the real footprint including overhang.
• Commodity description and NMFC item number — what you're shipping and its classification.
• Freight class — the class you're declaring (see What Is Freight Class?).

Special instructions and accessorials

The BOL is where you request services like liftgate, residential delivery, inside delivery, or appointment/notification. If a service is performed but wasn't noted, it can still be billed as an accessorial — so declare what you need up front, and don't declare what you don't.

Freight terms and liability

The BOL specifies whether the shipment is prepaid (shipper pays) or collect (consignee pays), and references the carrier's limits of liability. If your goods are worth more than the carrier's default per-pound liability, you may need to declare a higher value or arrange separate cargo insurance.

The most common BOL errors

• Estimated weights and dimensions instead of measured ones — the top cause of reweigh/re-class charges.
• Wrong or missing NMFC / class — leads to reclassification.
• Mismatched piece counts — delays and disputes at the dock.
• Undeclared accessorials — surprise line items on the invoice.

Because the BOL and the invoice should tell the same story, comparing them side by side is one of the fastest ways to catch billing errors — a mismatch in weight, class, or dimensions between the two is a red flag worth disputing.
