What Are the Key Techniques for Proper Container Loading?

Critical Rules for Mixed Cargo Loading
When exporting, shippers must avoid discrepancies between actual and declared cargo to prevent customs holds. Close coordination among exporters, warehouses, and freight forwarders is essential. Key rules include:
Avoid mixing differently shaped or packaged items.
Separate goods that leak dust, moisture, or odors—use tarps or plastic sheets if necessary.
Place lighter items atop heavier ones.
Stack fragile packaging over sturdier boxes.
Position liquids and cleaning agents at the bottom.
Cover sharp-edged items to prevent damage.
Expert Loading Techniques
Three primary methods exist: manual loading, forklift-assisted stacking, and fully mechanical loading (e.g., palletized goods). Follow these guidelines:
Never exceed max load limits (total weight minus container tare weight, marked on the door).
Know your cargo density—goods heavier than the container’s unit capacity are "heavy," others are "light." This distinction boosts efficiency.
Balance the load evenly—avoid off-center weight distribution.
Prevent concentrated pressure—use wooden planks under heavy machinery. Safe floor loads:
20’ container: 1,330 kg/m²
40’ container: 980 kg/m²
Follow handling symbols ("This Side Up," "Fragile") and never use hooks for bundled goods. Secure loose items with padding or plywood.
Optimize palletized loads by calculating container and cargo dimensions to minimize wasted space.
Forklift Loading Tips
Standard forklifts (2-ton capacity) have a ~50 cm free lift height; some models allow full-height stacking if container clearance permits.
For two-layer loading:
First layer height = Forklift’s max lift height minus free lift.
Always use dunnage (spacers) to slide forks out smoothly.
Final Reminders
Avoid naked cargo—even minimal packaging prevents damage.
Secure large items (e.g., machinery, construction materials) with straps or braces.
Attention to detail is the ultimate safeguard against errors.
