Ocean Bills of Lading: Types, Fields and How They Differ From a Truck BOL

The ocean bill of lading decides who can claim the cargo, which company is liable and what number the terminal, customs and your trucker will use to find the box. Here is how to read one.

What an ocean bill of lading does

An ocean bill of lading (B/L or BL) has three jobs. It is the carrier's receipt for the goods, stating what was received and in what apparent condition. It is evidence of the contract of carriage, with the carrier's terms on the back or by reference. And when it is negotiable, it is a document of title: whoever properly holds the original controls the cargo.

Under the Carriage of Goods by Sea Act (COGSA), which applies to ocean shipments to and from US ports, the carrier must issue a bill of lading on the shipper's request showing the shipping marks, the number of packages or the quantity or weight, and the apparent order and condition of the goods. After loading, the shipper can require a "shipped" bill of lading that confirms the goods are on board.

The main types

TypeNegotiable?How the cargo is releasedTypical use
Straight bill of ladingNo. Must be marked "nonnegotiable" or "not negotiable"To the named consigneeShipments between related companies or prepaid sales
Order (negotiable) bill of ladingYesTo whoever presents the properly endorsed originalLetter of credit sales; cargo sold while at sea
Sea waybillNoTo the named consignee without surrender of an originalRegular trade between trusted parties; avoids lost-original delays
Master bill (MBL)EitherIssued by the ocean carrier, usually to an NVOCC as shipperEvery containerized shipment moved through an NVOCC
House bill (HBL)EitherIssued by the NVOCC to the actual shipperYour contract when you book through an NVOCC
Received for shipment vs shipped on boardEitherNot a release method; shows whether goods were only received or actually loadedBanks under letters of credit usually require "shipped on board"

The negotiable and nonnegotiable distinction comes from the Federal Bills of Lading Act. Under 49 U.S.C. 80103, a bill is negotiable when it states that the goods are to be delivered "to the order of" a consignee and does not say on its face that it is not negotiable. A bill that states the goods are to be delivered to a named consignee is nonnegotiable, endorsing it does not make it negotiable, and the carrier must mark it "nonnegotiable" or "not negotiable."

Express or telex release

When an order or straight bill was issued in paper, the originals have to reach the destination before the carrier releases the cargo. To avoid that, shippers often surrender the originals at origin and the carrier issues a release message to its destination office. The industry calls this an express or telex release. The effect is similar to a sea waybill, but it happens after the original bill was issued.

House bill vs master bill

When you book through an NVOCC there are two bills for the same container. The ocean carrier issues a master bill to the NVOCC, which appears as shipper (and often its agent appears as consignee). The NVOCC issues a house bill to you, naming the real shipper and consignee. On an LCL shipment, one master bill covers the container and several house bills cover the individual shipments inside it.

This matters downstream. Customs data is tied to the lowest bill level: the Importer Security Filing is provided at the house bill level where one exists (19 CFR 149.3). The terminal and the ocean carrier, however, work from the master bill, because their customer is the NVOCC. A freight release on your house bill does nothing at the terminal until the NVOCC has cleared its own master bill with the carrier.

What the fields mean

FieldWhat it meansWatch for
ShipperParty contracting for carriage (seller or exporter on a house bill; the NVOCC on a master bill)Must match commercial documents
ConsigneeParty entitled to delivery. On an order bill this may read "to order" or "to order of [bank]""To order" with no endorsement leaves the cargo stuck
Notify partyWho receives the arrival notice. Naming one does not affect negotiabilityOften the customs broker or importer
Vessel and voyageThe ship and voyage number the cargo is booked onChanges if cargo is rolled to a later sailing
Port of loading / dischargeWhere the cargo goes on and comes off the shipPort of discharge drives the terminal and free time
Place of receipt / deliveryInland points if the carrier is responsible beyond the portsDecides whether the carrier or you arrange the drayage
Container and seal numbersBox identifiers and the seal applied at stuffingThe driver should check the seal at pickup
Marks, packages, description, weightThe COGSA receipt informationWeight must be realistic for US road limits
"Shipper's load, stow and count"The carrier did not see the cargo being loadedShortages inside a sealed box are hard to claim against the carrier
Freight prepaid / collectWhether ocean freight is paid at origin or by the consigneeCollect freight must be paid before release
Number of originalsHow many original bills were issued (often three)Any one original can release the cargo
Clean or clausedWhether the carrier noted damage or shortage at receiptBanks and buyers usually require a clean bill

Ocean BL vs truck BOL

Negotiable?Can beAlmost always a straight, nonnegotiable bill

On a container move, the drayage carrier does not carry the ocean bill. It works from the carrier's or terminal's release, a delivery order from the customer, and the equipment interchange receipt at the gate. If the drayage company issues its own bill or delivery receipt, that document governs the truck leg. Liability on the ocean leg and the truck leg can be very different, which matters when a box arrives damaged and nobody knows where it happened. Confirm what your load or rate confirmation says; see broker rate confirmations.

Common mistakes

  • Issuing an order bill when nobody needs one. If there is no letter of credit or sale in transit, a sea waybill avoids courier delays and demurrage while waiting for originals.
  • Losing or delaying originals. With a negotiable bill the carrier will not release without one, and replacing it usually means a bank guarantee or bond.
  • Sending a driver with only the house bill number. The terminal knows the master bill and the container number.
  • Not checking the seal. A seal number that does not match the bill at pickup should be noted on the interchange before leaving the terminal.
  • Declaring an unrealistic weight. A weight that is wrong on the bill gets the driver an overweight ticket on the road. Check against weight limits.
  • Assuming full value is covered. Without a declared value, ocean carrier liability under COGSA is $500 per package. Buy cargo insurance if the goods are worth more.

Questions

What is the difference between a straight bill of lading and an order bill of lading?

A straight bill names a consignee and the goods are delivered to that consignee; it is nonnegotiable and must be marked that way. An order bill states the goods are to be delivered to the order of a consignee, so it is negotiable and whoever properly holds the endorsed original can claim the cargo.

What is a sea waybill?

A sea waybill is a nonnegotiable transport document. The named consignee can take delivery by proving identity, without surrendering an original paper document, which avoids delays when originals are late.

Which bill of lading number do I give the trucker?

Terminals generally track import containers by the master bill of lading and the container number, since the terminal deals with the ocean carrier. If you only have a house bill from your NVOCC, ask the NVOCC for the master BL number and the container number before you dispatch the pickup.

Is the ocean carrier's liability the same as a trucker's?

No. Ocean carriage to or from the US is governed by the Carriage of Goods by Sea Act, which limits carrier liability to $500 per package unless a higher value is declared. Interstate motor carriers fall under the Carmack provisions in 49 U.S.C. 14706, which have different liability and claim rules.
