Step-by-step packing guide
Plan for the extra height
A High Cube gives you 2.70m of internal height — 31cm more than a standard container. This changes your stacking strategy entirely. Map out your cargo and identify items you can double-stack that would not fit in a standard box. Calculate whether the extra 4+ CBM of overhead space justifies the HC surcharge. For palletized cargo, plan two-high stacking if loaded pallet height is under 1.30m.
Inspect the container
Check the container for structural damage, holes, water ingress, and unusual odors before loading. Pay special attention to the roof — HC containers are taller and more prone to top-corner damage from low bridges and stacking impacts. Check the floor condition for soft spots. Test door seals and locking rods. Document any pre-existing damage with photos.
Load heaviest cargo first, keep the center of gravity low
Place the heaviest items on the floor at the front wall. With 2.70m of height available, there is a temptation to stack heavy items higher — resist this. A high center of gravity is more dangerous in a High Cube because the taller container has greater leverage during vessel rolling. Keep heavy items on the floor and use the extra height for lighter, voluminous cargo on top.
Double-stack pallets and use the full height
The HC's key advantage is double-stacking. Standard loaded pallets (1.20-1.30m high) can be stacked two-high within the 2.70m ceiling. Place stronger, heavier pallets on the bottom. Verify that bottom cartons can support the weight of the upper pallet. Use slip sheets or plywood between layers to distribute load evenly. Fill the remaining 10-30cm gap above the top pallet with void fill.
Fill the larger void space
More height means more potential void space above your cargo. Unfilled vertical gaps are dangerous — cargo can topple into this space during rough seas. Use large dunnage airbags between the top of cargo and the ceiling. For mixed loads with different heights, build up shorter sections with void fill to create a flat, stable top layer across the full length of the container.
Secure and document
Apply lashing straps to the container's lashing rings. With double-stacked cargo, use additional vertical lashing to prevent the upper tier from shifting. Install load bars across the door end at two heights if possible. Photograph each layer during loading and the final state before sealing. Record actual weight for VGM compliance and note that HC containers have a slightly higher tare weight.
Weight distribution rules
Keep heavy cargo on the bottom tier
With double-stacking in a High Cube, weight discipline becomes even more critical. Always place the heavier pallet on the bottom. The upper tier should be lighter, voluminous cargo. A top-heavy High Cube is more dangerous than a top-heavy standard container because the extra height creates greater leverage.
40/60 front-to-back split
Distribute cargo so approximately 40% of weight is in the front half and 60% near the doors. This is the same principle as standard containers but even more important for HC because the taller profile amplifies any front-to-back imbalance during crane lifts.
Even side-to-side balance
The 2.70m height makes lateral balance critical. A High Cube container that is heavier on one side creates a higher tipping moment than a standard box. Distribute weight evenly left-to-right across every layer, especially the upper tier.
Floor and stackability limits
The floor load rating is the same as standard containers (~3,000 kg/m²). But also check the stackability rating of your bottom-tier cargo — the upper pallet's full weight bears down on it. Most corrugated cartons lose 30-40% of compression strength in humid ocean transit conditions.
Loading Patterns Library
Optimize your container space with proven loading patterns for different cargo types
Column Stack Pattern
A simple and straightforward loading pattern with boxes stacked in vertical columns. Ideal for uniform cartons with good stacking strength.
Best For
- • Uniform, rigid cartons
- • Boxes with good stacking strength
- • When load stability is a priority
Efficiency
Pro Tips
- • Ensure columns are aligned vertically to maximize weight-bearing capacity of boxes
- • For added stability, consider plastic wrapping each column or adding corner protectors
- • Leave minimal gaps between columns to prevent shifting during transport
Interlocking Pattern
An advanced loading pattern where each layer alternates orientation, creating a more stable structure. This "brick-like" arrangement distributes weight more evenly and prevents collapse.
Best For
- • Cartons with moderate stacking strength
- • Medium to long distance shipping
- • When preventing collapse is critical
Efficiency
Pro Tips
- • Alternate the orientation of each layer by 90 degrees for maximum stability
- • Ensure boxes can support this load pattern - weaker boxes may crush despite interlocking
- • Creates better resistance against shifting during transit, reducing damage risk
Pinwheel Pattern
An efficient pattern where boxes are arranged in alternating orientations within the same layer, creating a pinwheel-like appearance. This maximizes space utilization and provides excellent stability.
Best For
- • Rectangular boxes with non-square dimensions
- • When maximum space utilization is needed
- • Shipments requiring both stability and efficiency
Efficiency
Pro Tips
- • Works best when box length is roughly twice its width (2:1 ratio)
- • Can improve stability and prevent shifting compared to simple stacking
- • For heavier goods, limit stack height and consider layer separation with slip sheets
Cargo Securing Techniques
Proper cargo securing is essential for safe and damage-free transport. Learn best practices for different cargo types and conditions.
Lashing & Tie-Down Techniques
Proper cargo lashing prevents movement during transport, reducing the risk of damage and ensuring safe delivery. Container ships can experience significant forces during transit, making secure cargo essential.
Understanding Lashing Points
Standard shipping containers come equipped with built-in lashing points in the floor, walls, and ceiling. These anchor points are designed to secure cargo with straps, ropes, or chains.
- • Floor lashing points can typically handle 2,000-5,000 kg of load
- • Wall and ceiling points usually have lower capacity (1,000-1,500 kg)
- • Always check the specific lashing point capacity in your container documentation
Effective Lashing Techniques
Diagonal Lashing
Straps run diagonally from the cargo to the lashing points, creating tension that prevents movement in multiple directions.
Loop Lashing
Straps form loops around the cargo and attach to lashing points on the same side, providing lateral stability.
Cross Lashing
Straps cross over the cargo in an X pattern, providing excellent stability against both lateral and longitudinal forces.
Direct Lashing
Straps connect directly from the cargo to the nearest lashing point, offering simple but effective restraint.
Pro Tips
- • Always use lashing points on opposite sides to create balanced tension
- • Check strap tension periodically during loading to account for settling
- • Use edge protectors where straps contact cargo edges to prevent damage
- • For heavy cargo, combine multiple lashing methods for redundancy
Essential Tie-Down Equipment
