How Does Sea Freight from China Work? A Step-by-Step Guide from Factory to Destination Port

Sea freight is one of the most widely used transportation methods for businesses importing goods from China. It is particularly suitable for large-volume, heavy or non-urgent shipments where transportation cost is an important consideration.

However, international sea freight involves many stages. A shipment may start at a Chinese factory, move to a warehouse or container yard, pass through export customs, depart from a Chinese port, arrive at the destination port, complete import procedures and finally be delivered to the buyer.

Understanding each step can help importers estimate costs, prepare documents, avoid delays and communicate more effectively with their China freight forwarder.

1. What Is Sea Freight from China?

Sea freight is the transportation of cargo by ocean vessel from a Chinese port to a destination port or inland location in another country.

China has several major commercial ports serving international trade, including ports in areas such as:

  • Shanghai
  • Ningbo
  • Shenzhen
  • Guangzhou
  • Qingdao
  • Xiamen
  • Tianjin

The appropriate port depends on the supplier’s location, cargo type, shipping route, vessel schedule and available services.

A typical shipment may follow this route:

Factory → China warehouse → Export customs → Origin port → Ocean vessel → Destination port → Import customs → Local delivery

The exact process depends on whether the shipment is FCL, LCL, port-to-port, door-to-door, DAP or DDP.


2. FCL vs. LCL Sea Freight

Before arranging ocean transportation, importers normally need to decide whether the shipment should use FCL or LCL.

FCL — Full Container Load

FCL means the cargo is transported using an entire container under the agreed shipping arrangement.

Common container types include:

  • 20-foot container
  • 40-foot container
  • 40-foot high-cube container

FCL is generally suitable for larger shipments.

Advantages may include:

  • Large cargo capacity
  • Simplified cargo handling
  • Better suitability for high-volume orders
  • Lower average transportation cost when the container is efficiently utilized

LCL — Less Than Container Load

LCL is used when the shipment does not require a full container.

Cargo from multiple customers is consolidated into one container.

LCL can be useful for:

  • Small commercial shipments
  • Trial orders
  • Inventory replenishment
  • Buyers who do not have enough cargo for a full container

However, LCL involves consolidation at origin and deconsolidation at destination.


3. Step 1: Confirm the Supplier and Cargo Information

The sea freight process begins with accurate cargo information.

The importer should provide the freight forwarder with:

  • Supplier name
  • Factory address
  • Product description
  • Quantity
  • Number of cartons
  • Gross weight
  • Carton dimensions
  • Total volume
  • Cargo value
  • Destination
  • Preferred delivery location

For example:

Product: Footwear
Quantity: 1,000 pairs
Cartons: 50
Gross weight: 850 kg
Volume: 6 CBM
Origin: Guangdong, China
Destination: Hamburg, Germany

The forwarder can use this information to determine whether FCL or LCL is more appropriate and prepare a preliminary quotation.


4. Step 2: Request and Compare Freight Quotations

After collecting the cargo information, the importer can request quotations from several freight forwarders.

A sea freight quotation may include:

  • Factory pickup
  • China domestic trucking
  • Warehouse handling
  • Export customs clearance
  • Origin terminal charges
  • Ocean freight
  • Documentation
  • Destination handling
  • Customs clearance
  • Final delivery

Not every quotation includes all of these services.

Therefore, buyers should ask:

“Which charges are included and which are excluded?”

This is more important than simply asking for the lowest ocean freight rate.


5. Step 3: Arrange Factory Pickup

Once the shipment is booked, the freight forwarder coordinates with the supplier.

The forwarder may arrange a truck to collect the cargo from the factory.

The supplier needs to ensure that:

  • Goods are ready
  • Packaging is complete
  • Carton quantity is accurate
  • Shipping marks are correct
  • Documents are prepared
  • Cargo can be loaded on schedule

For FCL shipments, an empty container may be delivered to the factory for loading, depending on the agreed logistics arrangement.

For LCL shipments, the supplier may send the cargo to a designated consolidation warehouse.


6. Step 4: Warehouse Receiving and Cargo Checking

For LCL shipments or consolidated cargo, the goods may first arrive at a freight forwarder’s warehouse.

Warehouse staff may check:

  • Number of cartons
  • Gross weight
  • Dimensions
  • Packaging condition
  • Shipping marks
  • Cargo identification

If the actual weight or volume differs significantly from the information originally provided, the freight cost may be adjusted.

For this reason, importers should provide final cargo measurements whenever possible.


7. Step 5: Container Loading

For FCL shipments, cargo is loaded into a container.

Proper container loading is important because poor loading can cause:

  • Product damage
  • Shifting cargo
  • Broken packaging
  • Uneven weight distribution
  • Difficult unloading

Heavy cargo should be positioned appropriately, while fragile products may require additional protection.

For some products, pallets, straps, corner protection or other securing methods may be appropriate.

The exact loading method depends on the cargo.


8. Step 6: Export Customs Clearance in China

Before the cargo can leave China, export customs procedures must be completed according to applicable requirements.

The shipment may require information such as:

  • Commercial invoice
  • Packing list
  • Product description
  • HS classification
  • Export declaration information
  • Other applicable documents

The exporter is responsible for ensuring that the cargo information is accurate.

Incorrect product descriptions or incomplete documentation can cause delays or additional customs requirements.

A professional freight forwarder can coordinate the customs process, but the exporter and importer should still provide accurate information.


9. Step 7: Cargo Moves to the Port

After the required export procedures are completed, the cargo is transported to the port.

Depending on the arrangement, this may involve:

  • Truck transportation
  • Container yard
  • Terminal handling
  • Port security procedures
  • Loading arrangements

The cargo must arrive according to the required cutoff time.

Missing a vessel cutoff can result in the shipment being moved to a later sailing.


10. Step 8: Ocean Vessel Departure

Once the container has been accepted by the carrier and loaded onto the vessel, the ship departs from the Chinese port.

At this stage, the importer may receive shipping information such as:

  • Vessel name
  • Voyage number
  • Container number
  • Bill of lading information
  • Estimated departure
  • Estimated arrival

The freight forwarder may provide tracking updates during the international transportation stage.


11. Step 9: Ocean Transportation

The container is transported by sea to the destination port.

Transit time varies depending on:

  • Origin port
  • Destination port
  • Shipping route
  • Carrier
  • Direct or transshipment service
  • Weather
  • Port congestion
  • Operational conditions

Importers should avoid treating a quoted transit time as an absolute guarantee.

Ocean schedules can change because of circumstances outside the control of the freight forwarder.


12. Step 10: Arrival at the Destination Port

After the vessel reaches the destination port, the container is discharged.

At this point, several procedures may occur before the cargo can be released.

These can include:

  • Terminal processing
  • Import documentation
  • Customs declaration
  • Customs inspection if required
  • Payment of applicable duties and taxes
  • Cargo release

The exact process depends on the destination country.


13. Step 11: Import Customs Clearance

Import customs clearance is one of the most important stages.

Customs authorities may review:

  • Product description
  • HS code
  • Customs value
  • Country of origin
  • Import documents
  • Product compliance
  • Applicable duties and taxes

The importer may need to provide additional documentation depending on the cargo.

If customs requires an inspection, the shipment may take longer and additional costs may apply.

A freight forwarder or customs broker can assist with the process depending on the agreed service.


14. Step 12: Payment of Duties and Taxes

Depending on the Incoterm and shipping arrangement, the buyer or seller may be responsible for import duties and taxes.

Possible charges include:

  • Customs duty
  • Import VAT
  • GST
  • Other applicable taxes

The amount depends on the destination country’s regulations and the classification and value of the goods.

Importers should not assume that ocean freight automatically includes customs duties and taxes.


15. Step 13: Container Release

After the necessary customs and terminal procedures have been completed, the container can be released according to the applicable process.

The forwarder may coordinate:

  • Container release
  • Delivery appointment
  • Trucking
  • Warehouse delivery

Importers should monitor the free time available for the container and arrange delivery promptly.

Delays can potentially lead to additional storage, demurrage or detention costs.


16. Step 14: Final Delivery

If the shipment is arranged as door-to-door service, the cargo will be transported from the destination port to the agreed delivery address.

The destination may be:

  • Warehouse
  • Factory
  • Distribution center
  • Office
  • Retail store
  • Other commercial location

The final delivery cost can depend on:

  • Distance
  • Cargo weight
  • Container type
  • Delivery address
  • Appointment requirements
  • Local regulations
  • Remote-area conditions

The buyer should confirm whether these costs are included in the original quotation.


17. What Documents Are Used for Sea Freight?

The exact documentation depends on the shipment, but common documents include:

Commercial Invoice

Shows transaction and cargo value information.

Packing List

Provides information about cartons, quantities, weight and packaging.

Bill of Lading

The bill of lading is a key document for ocean transportation.

Certificate of Origin

May be required depending on the destination and trade requirements.

Customs Documents

Export and import customs may require additional information or declarations.

Product Certificates

Certain products may require additional certificates or compliance documents.

Importers should confirm documentation requirements before the shipment leaves China.


18. Understanding Ocean Freight Costs

A sea freight quotation can contain multiple cost components.

These may include:

  • Factory pickup
  • China domestic trucking
  • Warehouse handling
  • Export customs
  • Terminal handling
  • Ocean freight
  • Documentation
  • Destination handling
  • Customs clearance
  • Final delivery
  • Duties and taxes
  • Insurance

The quotation should clearly state which costs are included.

For example, a quotation of “USD 800 ocean freight” does not necessarily mean that the entire shipment will cost only USD 800.


19. What Is CBM in Sea Freight?

CBM means cubic meter.

It is commonly used when calculating the volume of LCL cargo.

For example, if one carton measures:

50 cm × 40 cm × 30 cm

The volume is:

0.5 × 0.4 × 0.3 = 0.06 CBM

If there are 20 identical cartons:

0.06 × 20 = 1.2 CBM

The freight forwarder can use the total volume to determine the applicable LCL transportation cost according to the route and pricing rules.


20. How to Choose Between FCL and LCL

The right option depends on:

  • Cargo volume
  • Cargo weight
  • Product characteristics
  • Destination
  • Budget
  • Required delivery time

FCL may be appropriate when the shipment efficiently uses a container.

LCL may be more suitable when the cargo volume is relatively small.

However, there is no universal CBM threshold that applies to every route. Container rates, LCL rates, local charges and destination fees can vary.

The best approach is to ask the freight forwarder to compare both options based on your actual shipment.


21. What Is Port-to-Port Shipping?

Port-to-port shipping generally means the main ocean transportation is arranged between the agreed origin port and destination port.

The buyer may still need to arrange:

  • Factory pickup
  • Export customs
  • Import customs
  • Destination transportation
  • Final delivery

Therefore, port-to-port service requires more coordination from the importer than door-to-door service.


22. What Is Door-to-Door Sea Freight?

Door-to-door sea freight means the logistics provider coordinates transportation from the origin location to the final agreed destination.

A typical route may be:

Factory → China warehouse/port → Export customs → Ocean freight → Destination port → Import customs → Local trucking → Buyer

This can be convenient for importers who do not have their own logistics team.

However, always confirm exactly what is included in the door-to-door quotation.


23. DDP Sea Freight from China

DDP sea freight is sometimes used by overseas buyers who want a simplified import process.

A typical arrangement may involve:

  1. Pickup from the Chinese supplier
  2. Export customs
  3. Ocean transportation
  4. Destination customs
  5. Applicable duties and taxes
  6. Local delivery

However, DDP does not remove the need to comply with destination-country import regulations.

Before booking DDP sea freight, confirm:

  • Product eligibility
  • Import requirements
  • Duties and taxes
  • Customs clearance
  • Final delivery
  • Additional charges
  • Importer-of-record responsibilities where applicable

24. Common Problems in China Sea Freight

Incorrect Cargo Information

If the actual cargo volume differs from the quoted volume, the final price may change.

Missing Documents

Incomplete documentation can delay customs clearance.

Missed Cutoff

If cargo misses the carrier’s cutoff, it may need to wait for a later sailing.

Port Congestion

Congestion can affect vessel schedules and cargo release.

Customs Inspection

A customs inspection may increase processing time and potentially create additional charges.

Poor Packaging

Inadequate packaging can result in damage during handling and transportation.

Unexpected Destination Charges

Some quotations exclude destination-side costs.


25. How to Reduce Sea Freight Costs

Importers can take several practical steps.

Consolidate Multiple Orders

Cargo from several suppliers can sometimes be consolidated into one shipment.

Optimize Carton Size

Reducing unnecessary packaging can improve container utilization.

Plan Orders Earlier

Advance planning provides more flexibility when selecting shipping schedules.

Compare FCL and LCL

Do not automatically choose one without comparing the complete costs.

Compare Multiple Forwarders

Obtain several quotations with the same service requirements.

Avoid Last-Minute Changes

Changes after booking can create additional handling or documentation costs.

Reduce Storage Time

Prompt customs clearance and delivery can help minimize storage-related charges.


26. How to Select a Reliable China Sea Freight Forwarder

When evaluating a freight forwarder, consider:

  • Experience with your destination
  • Port coverage
  • Carrier options
  • LCL consolidation capability
  • FCL experience
  • Customs support
  • Documentation quality
  • Communication
  • Shipment tracking
  • Pricing transparency
  • Destination delivery capability

A good freight forwarder should be able to explain the entire shipping process rather than simply providing an ocean freight rate.


27. What Information Should You Send for a Sea Freight Quote?

A useful inquiry should include:

Product:
What are you shipping?

Quantity:
How many units?

Cartons:
How many cartons or pallets?

Dimensions:
Length × width × height.

Weight:
Gross weight.

Volume:
Total CBM if available.

Origin:
Supplier city and pickup address.

Destination:
Port or complete delivery address.

Shipping method:
FCL or LCL.

Service:
Port-to-port, DAP or DDP.

Cargo type:
General cargo or special cargo.

Providing this information helps the freight forwarder produce a more accurate quotation.
