How to Load a Shipping Container: Complete Guide

Proper container loading reduces shipping costs, prevents cargo damage, and ensures compliance with international regulations. This guide walks you through the entire process.

Step 1: Calculate Your Cargo Volume and Weight

Before loading, you need to know:

• Total CBM (cubic meters) of all cargo
• Total weight of all cargo
• Dimensions of each carton or pallet

Step 2: Choose the Right Container

Step 3: Inspect the Container

Before loading, always inspect the container for:

• Holes, rust, or structural damage
• Clean floor with no moisture or odors
• Working locking mechanisms on doors
• Valid CSC (Container Safety Convention) plate

Step 4: Plan Your Loading Order

The golden rules of container loading:

1. Heaviest cargo first — place heavy items at the bottom and near the front (door end)
2. Even weight distribution — spread weight evenly left and right
3. Fill vertical space — stack boxes to container ceiling when possible
4. Fragile items last — place delicate cargo on top
5. Like with like — group similar sized cartons together

Step 6: Secure the Cargo

• Use dunnage bags or airbags to fill voids
• Strap heavy items to container lashing rings
• Use corner protectors for sharp-edged cartons
• Apply stretch wrap to palletized cargo

Common Container Loading Mistakes

• Loading without a plan — leads to poor space utilization (often below 60%)
• Overloading one side — can cause container to tip during transport
• Ignoring moisture — use desiccants in humid cargo environments
• Not securing cargo — goods shift during sea voyage causing damage
