In international trade, cargo arriving at the destination port does not mean it is immediately ready for pickup. Before the consignee can physically collect the goods, a crucial step must be completed — cargo release, ，通常被称为 “B/L exchange” or “Delivery Order (D/O) issuance.”
This process is a mandatory bridge between ocean transportation and final cargo pickup, ensuring legal ownership transfer, regulatory compliance, and fee settlement.
What Is Cargo Release (B/L Exchange)?
Cargo release refers to the process in which the consignee named on the Bill of Lading (B/L) presents the required original shipping documents to the shipping line or its appointed agent, in exchange for a Delivery Order (D/O).
Bill of Lading (B/L):
A legal document issued by the carrier that serves as:A receipt of goods
A contract of carriage
A document of title representing ownership of the cargo
Delivery Order (D/O):
A non-transferable cargo pickup authorization issued by the carrier or agent, allowing the consignee to:Complete customs clearance
Collect cargo from the terminal, warehouse, or CFS
Without a valid D/O, cargo cannot be released, even if it has already arrived at the port.
Why Is the Delivery Order (D/O) So Important?
1. Legal Control of Cargo Ownership
该 Bill of Lading controls who legally owns the cargo, while the Delivery Order controls who is authorized to collect it.
Original B/L must be surrendered (for negotiable B/Ls)
Carrier verifies consignee identity and endorsement
D/O is issued only after ownership confirmation
This prevents unauthorized cargo release and protects all parties involved.
2. A Key Regulatory and Customs Control Point
Cargo release is a critical checkpoint for customs, port authorities, and terminal operators.
Through the D/O system:
Cargo information is synchronized with customs systems
Port operators verify release status before allowing pickup
Regulatory supervision remains complete and traceable
This ensures compliance with import regulations and maintains a secure logistics chain.
3. Settlement of Local Charges and Port Fees
The cargo release stage is also when 目的地费用 are settled, which may include:
Terminal Handling Charges (THC)
Documentation fees
Container stripping or devanning fees
Port miscellaneous charges
Delivery Order fees
Fee structures and amounts may vary depending on:
航运公司
目的港
FCL or LCL shipment type
Only after all required charges are paid will the D/O be issued.
Is Cargo Release Required for Both FCL and LCL Shipments?
Yes.
Whether the shipment is 整箱运输（FCL） 或 拼箱（LCL）, cargo release is mandatory.
Although LCL cargo is consolidated:
Shipping lines still transport goods by container
Consignees must obtain a D/O to collect cargo from the CFS
简而言之，, every ocean shipment requires cargo release, regardless of shipment size.
Types of Bills of Lading and Their Impact on Cargo Release
| B/L Type | Transferable | Original Required for D/O |
|---|---|---|
| Negotiable B/L (To Order) | 是的 | 是的 |
| Straight B/L | 不 | Usually Yes |
| Sea Waybill | 不 | No original needed |
Understanding the B/L type is essential, as it directly affects:
Release timing
Documentation requirements
Risk control
Common Risks of Delayed Cargo Release
Failure to complete cargo release on time may result in:
Demurrage and detention charges
Storage fees at terminal or warehouse
Missed customs clearance windows
Delivery delays to end customers
Proper planning and early document preparation are key to avoiding unnecessary costs.
Conclusion: Cargo Release Is the Bridge Between Shipping and Delivery
Cargo release is not a formality — it is a mandatory legal and operational process that connects ocean transportation with final cargo pickup.
By exchanging the Bill of Lading for a Delivery Order, consignees:
Confirm cargo ownership
Comply with customs and port regulations
Settle destination charges
Secure lawful cargo delivery
When managed correctly, cargo release ensures your shipment moves smoothly from vessel to warehouse — on time and without surprises.
