How to Pack Goods for Ocean Freight

Proper packing is one of the most critical steps in ocean freight shipping. Goods that are poorly packed are prone to damage, moisture exposure, rust, or shifting during transit. Whether you are shipping from China to the USA, Canada, or Europe, knowing how to pack cargo effectively ensures safe delivery, reduces insurance claims, and can even save on shipping costs.

1. Step 1: Choose the Right Packaging Materials

• Sturdy cartons: Double-walled cardboard is recommended for most goods

• Pallets: Standard wooden or plastic pallets help stabilize cargo for forklifts and container loading

• Shrink wrap / stretch film: Secures cartons to pallets to prevent shifting

• Cushioning materials: Bubble wrap, foam, or air pillows protect fragile items

• Waterproof packaging: For products sensitive to moisture or condensation

💡 Tip: Using high-quality packaging reduces damage claims and insurance costs.

2. Step 2: Consider Cargo Type

Different goods require different packing methods:

3. Step 3: Optimize Palletizing

• Place heavier cartons at the bottom and lighter ones on top

• Avoid overhanging cartons to prevent damage during container handling

• Keep pallets within standard container dimensions (20ft or 40ft) to maximize space and avoid extra charges

• Label pallets clearly with:

  • Shipping marks

  • Consignee information

  • Weight and dimensions

  
  

💡 Tip: Proper palletizing also reduces LCL consolidation risk and ensures containers are loaded efficiently.

4. Step 4: Protect Against Moisture and Contamination

• Use plastic liners or desiccants inside cartons for moisture-sensitive cargo

• Seal cartons tightly to avoid dust, dirt, or insects

• For long ocean transit, consider anti-rust treatments for metals

5. Step 5: Container Loading Tips

• Distribute weight evenly within the container to prevent shifting at sea

• Fill gaps with dunnage or airbags for stability

• Avoid stacking beyond safe limits for fragile items

• Ensure compliance with container weight limits to avoid port penalties

💡 Insight: Proper loading reduces risk of cargo damage and container imbalance.

6. Step 6: Documentation and Labeling

• Each carton and pallet should include:

  • Commercial Invoice reference

  • Packing list number

  • Shipping marks (destination, handling instructions)

  
  

• Ensure labels are durable and weatherproof for ocean transit

7. 7. Risk Management Considerations

• Insurance: Even with perfect packing, ocean freight carries risks like rough seas or port handling

• High-value items: Use extra layers of protection and consider double boxing or wooden crates

• LCL shipments: Be extra careful—your cargo may be handled multiple times during consolidation

💡 Example: Forwarders like WAYTRON LOGISTICS LIMITED advise clients on packing standards and provide detailed checklists to minimize damage for LCL and FCL shipments from China to North America.

2. Use standardized carton sizes for easier container loading

3. Clearly label fragile and hazardous cargo

4. Work with a forwarder for advice on proper packing for your cargo type

5. Document packing methods for insurance purposes
