Bill of Lading (BOL) Explained: How to Read & Fill One Out Correctly

The bill of lading, the BOL, is the single most important piece of paper in freight shipping. It's a contract, a receipt, and a title document all in one. When something goes wrong with a shipment, the BOL is what determines who's liable, who pays, and who wins the dispute. Knowing how to fill one out correctly isn't optional, it's the difference between a clean claim and a denied one.

What a BOL is (and isn't)

A BOL is three things at once:

• A contract between the shipper and the carrier specifying what's being shipped, from where, to whom, and under what terms.
• A receipt proving the carrier took possession of the freight at the agreed condition and quantity.
• A title document, in some forms, that can transfer ownership of the freight in transit.

It is not the same as a packing slip (which is just a contents list for the consignee) or a freight invoice (which is the billing document the carrier sends after delivery).

The required fields on every BOL

Every standard BOL has the same core fields. Here's what each one means and what to put in it.

Shipper (or Consignor)

The party from which the freight is being picked up. Include the full legal company name, the pickup address (including suite/dock number), city, state, and ZIP. This must match the actual pickup location, not a headquarters address if pickup is at a warehouse.

Consignee

The party receiving the freight. Same level of detail as the shipper. If the receiver requires an appointment, include the contact name and phone number for scheduling.

Carrier name and SCAC code

The trucking company hauling the freight, including the carrier's SCAC, Standard Carrier Alpha Code, a 2-4 letter identifier used by every authorized motor carrier. Your broker will fill this in.

BOL number

A unique identifier for the shipment, generated by the shipper or broker. Used for tracking and on all subsequent paperwork (PODs, invoices, claims).

Pro number (carrier-assigned)

The carrier's internal tracking number, added after pickup. It is different from the BOL number: the BOL number is yours, the pro number is the carrier's.

Special instructions

Anything the driver needs to know that isn't covered elsewhere, appointment requirements, gate codes, specific contact names, hazmat handling instructions, "do not stack" notes for fragile freight.

Freight description

The most important section and the one most often filled out incorrectly. For each line item you need:

• Number of pieces and packaging type ("2 pallets," "5 crates," "1 skid").
• Description of contents, specific enough that the carrier knows what they're hauling. "Auto parts" is too vague. "Steel transmission housings, packaged in cardboard" is right.
• NMFC item number and freight class (LTL only).
• Weight, actual scaled weight, not estimated.
• Dimensions (L × W × H), actual measured dimensions.

Hazmat declaration

If any part of the shipment is hazardous material, the BOL must be a hazmat-compliant BOL with the proper UN number, proper shipping name, hazard class, packing group, and emergency contact information. Hazmat on a non-hazmat BOL is a federal violation.

Freight terms (collect / prepaid / third party)

Who's paying for the freight:

• Prepaid: Shipper pays the carrier directly.
• Collect: Consignee pays on delivery.
• Third party: A broker or other party pays, common when shipping through a freight broker.

Declared value

The dollar value of the freight, used for insurance and claim purposes. Carrier liability is limited by federal law, declared value lets you increase coverage above the default. Without a declared value, LTL carrier liability is typically capped at $25 per pound for most classes, far less than the actual value of high-value freight.

Signatures and condition

The driver signs the BOL at pickup acknowledging receipt of the freight at the stated condition. The consignee signs at delivery acknowledging receipt. Any visible damage at pickup or delivery should be noted on the BOL before signing, without that notation, the carrier is presumed to have received and delivered the freight in good condition, and damage claims become nearly impossible to win.

The four common types of BOL

1. Straight BOL

The standard non-negotiable BOL. Freight goes from shipper to a specific named consignee. Cannot be transferred. The default for almost all domestic freight.

2. Order BOL (negotiable BOL)

Negotiable, the title to the freight transfers with the BOL. Used when freight is being shipped as part of a financial transaction (e.x., shipment against a letter of credit, COD shipments). The consignee must produce the original BOL to receive the freight.

3. Master BOL

A consolidated BOL covering multiple shipments going to the same destination on the same truck. Used in LTL consolidation and broker arrangements.

4. House BOL

Issued by a freight forwarder or broker to the shipper, separate from the master BOL the carrier issues to the broker. Used in multi-tier freight arrangements.

The mistakes that lose claims

When freight is damaged in transit, the BOL is what wins or loses the claim. The most common BOL mistakes:

• Signing "clear" when freight is visibly damaged. The driver hands you the BOL, you sign without checking, and the freight has a crushed corner. You just signed that it was received in good condition. The carrier will deny the claim.
• Vague freight descriptions. "Auto parts" doesn't tell the claims department anything. They'll deny vague claims because they can't verify the value.
• No declared value. If your $50,000 machinery shipment doesn't have a declared value on the BOL, the carrier's liability is capped at the default limit, often a tiny fraction of the actual value.
• Incorrect weights and dimensions. Misrepresented freight gets reclassified in transit and may not be covered under the same liability terms.
• Missing pieces undeclared. If the consignee receives 8 of 10 pallets and signs the BOL "clear" without noting the shortage, the claim for the missing 2 pallets is essentially dead.

Electronic vs paper BOLs

Most carriers now accept (or require) electronic BOLs delivered through their TMS or via API. They're legally equivalent to paper BOLs and have the advantage of automatic tracking, no lost paperwork, and standardized formats. The downside is fewer opportunities to catch errors visually before signing, make sure whoever signs at pickup and delivery is still looking carefully at the document, not just clicking through.

The bottom line

The BOL is the most leverage you have in freight shipping. Fill it out completely and accurately, declare the actual value of the freight, describe the contents specifically, and never sign at pickup or delivery without checking the freight against what the document says. The shippers who lose claims aren't usually the ones whose freight was damaged, they're the ones whose BOLs gave the carrier an opening to deny coverage.
