Export Frame Container Operations Explained

The export of frame containers generally follows the steps below:

1. Box Calculation Based on Project's Procurement Plan and Actual Shipment List

2. Inquire for Quotes, Compare Prices, and Book Space

3. Develop a Cargo Collection and Loading Plan, Prepare Complete Export Customs Documents

4. On-Site Loading, Securing, and Inspection Handover

5. Export Customs Declaration

6. Port Collection and Loading onto Ship

Among these steps, the first four are the most critical:

(1) Box Calculation Based on Project's Procurement Plan and Actual Shipment List

Special attention is needed in this step:

• Communicate with relevant procurement personnel and suppliers to obtain accurate cargo data based on the shipment plan. This is the foundation for accurate box calculation.

• Based on the cargo data (preferably through on-site cargo inspection), conduct reasonable box calculations to minimize the number of boxes, reduce over-length, over-width, and over-height issues, and ensure balanced weight distribution.

It's important to note that different shipping companies have different requirements and restrictions on dimensions and weights. For example, CMA typically does not accept over-length cargo (over 11.8 meters) in frame containers, and also has weight restrictions such as 28 tons for a 20' FR and 32 tons for a 40' FR. Therefore, understanding these restrictions is essential when making box calculations.

(2) Inquire for Quotes, Compare Prices, and Book Space

After the calculation, request ocean freight quotes by providing the following details:

• A detailed cargo list, including weight and dimensions of each item

• Port of origin and destination

• Estimated shipment date

• Desired container type and quantity

(3) Develop Cargo Collection, Repositioning, and Loading Plan, Prepare Complete Export Customs Documents

Based on the feedback received, discuss the cargo collection and loading plan, ensuring the following details:

• Cargo Collection: Decide whether to collect cargo at the factory or from a warehouse, which will determine the timing and delivery location.

• Loading Plan: Confirm the loading time, site, equipment, manpower, and the availability of securing materials.

(4) On-Site Loading, Securing, and Inspection Handover

Since frame containers are often used for oversized and heavy cargo, loading usually involves cranes. Special attention should be paid during loading:

• Ensure the cargo's center of gravity is as low as possible to increase stability.

• Distribute the weight evenly and center it. During loading, ensure the cargo is placed correctly on the frame container to avoid over-length or over-width.

• If the contact points are unstable, such as with cylindrical items or small contact surfaces, use dunnage to ensure stable contact between the cargo and container.

Frame Container Securing

Securing is the core step to ensure cargo safety. Some shipping companies may require professional inspection companies to verify the securing before loading, providing a report before the cargo can be loaded. Pay attention to:

• Use appropriate thickness steel wire ropes and ropes depending on the cargo type, as well as the proper fastening devices like shackles and tensioners.

• The security points must be strong enough to prevent cargo shifting.

• Use cross-tying or symmetrical tying methods to increase the strength of the securing.

• Add dunnage (like old rubber tires) at the contact points to protect the cargo and avoid static electricity, sparks, or damage during transport.

Inspection Handover

The final step is to inspect the securing process to ensure:

• The securing is balanced and symmetrical.

• Each securing point is tight, and the steel wire rope is properly tensioned.

• If securing straps are used, they should be tight and perpendicular to the container's base.

Due to its special design, frame containers are primarily used to transport oversized cargo, particularly equipment and machinery. A deeper understanding of frame container operations is essential for controlling relevant operations and providing professional services for projects.
