Best Practices for Safe Container Shipping
Adhering to best practices can help in securing cargo, preventing delays and making the entire transportation process easy.
Select a Suitable Container Type
The type of cargo you have will determine which type of container you will use. For example, choose reefer containers if you are transporting perishable cargo or flat rack containers when shipping large machines.
Check the Condition of the Container before Loading Cargo
It is important to inspect the container and look for any signs of dents, cracks, leakage, rusting or damage on the door seal of the container. An inspection will help prevent damage to the cargo caused by leaks or structural damages.
Distribute Weight Evenly in the Container
Heavy cargo should be loaded at the bottom and distributed evenly throughout the container. This will provide even distribution of weight and enhance the stability of the cargo.
Proper Packaging of Goods and Securely Fixing the Goods in the Container
Goods should be packaged using appropriate packaging materials and fixed to prevent them from moving around.
Seal the Container Properly
A high-security seal should be placed on the container once the goods are loaded.
Keep Documentation Correct
Make sure that all shipping documentation, like the Bill of Lading, Commercial Invoice and Packing List are accurate. Documentation ensures that there will be no problem in customs clearance.
Track Shipment
Keep track of your shipment using tracking services to know where it is and how long it will take to reach you. Tracking helps you act immediately if there is any delay or problem.
Things You Should Definitely Not Do
Making a mistake in shipping process is very dangerous because you may cause various problems like delays, damage of the cargo and extra expenses.
Wrong Container Selection
If you choose an inappropriate container, it may not be enough for cargo. The container may either not provide enough space for the cargo or adequate protection.
Overfilling the Container
Overloading the container can cause damage to the container and create safety issues during shipment.
Unsecure Cargo Packing
If the cargo is not properly packed and secured in the container, it may move and get damaged during transportation.
Incorrect Document Submission
Errors in submission of the shipping documents (for example, Commercial Invoice or Bill of Lading) will lead to delays and penalties.
Not Knowing the Customs Regulations
Every country has their own regulations concerning imports and exports of products. Ignoring the customs regulations is likely to cause delays and additional expenses.
Damaged Container
Rust, dents, leakage or improperly sealed doors can cause moisture contamination of the cargo during shipment.
