How to load a shipping container more efficiently: Tips and best practices

Loading a shipping container isn’t just about stacking boxes – poor planning can lead to wasted space, damaged cargo, and costly delays.

Read this guide for proven tips on how to load a shipping container faster, safer, and more efficiently.

Why efficient container loading matters

Efficient loading drives lower costs, faster deliveries, safer operations, and more sustainable shipping.

Cost savings

Globally, shipping containers are underfilled by an average of 35%. Maximizing capacity can save you thousands each month and keep your business competitive.

Time efficiency

Only 60% of port time goes to actual cargo operations – the rest is often lost to handovers and waiting. With a solid loading plan and the right equipment, you’ll cut turnaround times and avoid costly demurrage fees.

Cargo safety

Proper weight distribution, bracing, and securing reduce the risk of cargo shifting or damage during transit. How you load matters as much as what you load, especially for long-haul shipping.

Workplace safety

Overloaded or poorly balanced containers can be dangerous to handle. Safe loading techniques reduce manual handling, minimize accidents, and protect both staff and shippers.

Sustainability

Efficient loading means fewer containers shipped, lower fuel consumption, and reduced carbon emissions, helping you stay compliant with growing sustainability targets.

Prepare before you load

Successful container loading begins long before the first boxes are lifted. Smart preparation saves time, protects cargo, and maximizes space.

Measure and plan

Get accurate cargo dimensions, weight, and volume. Accurate measurements help plan stacking, balance weight, and reduce empty space.

Pro tip: Create a detailed cargo manifest with exact dimensions (LxWxH), weight, fragility ratings, and packaging type. It prevents costly restuffing and delays at the port.

Check weight limits and shipping regulations to avoid fines or being held liable for safety violations.

Choose the right container

Picking the right container upfront avoids last-minute swaps, delays, or damage during transit and ensures compliance with destination country rules:

• Dry cargo containers: Standard goods, electronics, textiles, auto parts, etc.
• High cubes: Lightweight, bulky cargo like furniture or machinery
• Flat racks: Oversized equipment, vehicles, construction gear
• Open tops: Tall cargo loaded by crane
• Refrigerated containers: Temperature-sensitive goods like food, chemicals, and pharma

Consider the type of load, ventilation, temperature requirements, and storage conditions.

Inspect the container before loading:

• Floor integrity (no holes, soft spots, or protruding nails)
• Wall and roof condition (no dents, holes, or rust)
• Door seals and locking mechanisms
• Cleanliness and absence of odors or residue

Organize your cargo

Group items by weight, size, and fragility. Place heavier items on the floor for stability and secure delicate items with packing materials, pallets, or other supports.

Organizing in advance reduces mid-load adjustments and keeps goods intact until the final destination.

Use a load plan

A visual plan saves hours and prevents wasted space. Use load-planning software to calculate stacking, weight distribution, and securing points. Even a simple sketch or diagram helps minimize shifting risks and wasted space.

A solid plan should include:

• Item placement order
• Weight distribution map
• Securing point locations
• Unloading access needs
• Special handling instructions

Best practices for loading a shipping container

The right techniques improve safety, efficiency, and cost-effectiveness. Follow these best practices to optimize your loading process and avoid common mistakes.

Start with the heaviest items

Load the heaviest cargo first, placing it on the bottom and near the container’s center of gravity. This method creates a stable base, prevents shifting, and reduces tipping risks.

Guidelines:

• Keep heavy items within the middle third of the container.
• Follow the CTU Code: no more than 60% of the total weight in half of the container length.
• Distribute across the full width when possible.

Heavy machinery, raw materials, and palletized bulk goods should go in first before lighter cargo.

Distribute weight evenly

Avoid stacking all heavy items on one side, as this can cause tipping, shifting, or uneven stress on the container floor.

Spread weight evenly front-to-back and side-to-side to maintain stability during loading, unloading, and transport by truck or trailer. Balanced weight reduces safety hazards and protects both the cargo and the container.

Secure fragile cargo

About 65% of damaged cargo claims result from poor packing within containers. Use dunnage, padding, straps, or bracing to secure delicate goods and prevent them from moving.

Glassware, electronics, furniture, and other sensitive goods should always be stabilized, especially when they’ll ship long distances.

Maximize vertical space

Use the container’s full height without compromising safety. Stack boxes and pallets carefully, keeping heavier items on the bottom. Use locking patterns to keep stacks stable and minimize movement.

Proper stacking increases space efficiency, reduces the number of trips needed, and lowers freight shipping costs.

Prevent moisture and contamination

Protect cargo from humidity, pests, and contamination:

• Use desiccants, pallets, and ventilation for moisture-sensitive goods.
• Keep cargo off the floor to prevent mold and corrosion.
• Inspect containers for leaks, damp spots, and residue, especially when shipping food or hazardous materials.

Follow safety protocols and procedures

Pre-loading checklist:

• Ensure the loading dock is level and secure
• Set container brakes and truck wheel chocks
• Verify loading equipment is certified and operational
• Require PPE for all personnel
• Establish clear communication among the team

During loading:

• Follow manual lifting guidelines (NIOSH recommends max 23kg/51lbs)
• Use mechanical aids for heavier, hard-to-carry items
• Keep walkways clear and well-lit
• Adhere to your organization's safety policies and local regulations

Comply with international standards

Incorrect container stuffing can cause fines, delays, or rejected shipments. Follow key regulations and standards:

1. CTU Code: Safe container stuffing and securing
2. SOLAS VGM: Verified Gross Mass must be declared before vessel loading
3. IMDG Code: Safe handling of hazardous goods
4. Customs rules: Accurate documentation and cargo declarations

Compliance checklist:

• Cargo weight verified and documented
• Dangerous goods classified and segregated
• Load securement meets CTU Code standards
• All documentation is complete and accurate
• Container seals applied and recorded

Tools for efficient container stuffing

The right technology can help you load faster, use space smarter, and protect your cargo while keeping costs under control. Here are four powerful tools that make a real difference.
