Shipping containers are those large, rectangular metal boxes that you see stacked on cargo ships and truck trailers. They’re a cornerstone of the global economy and make international trade possible on such a massive scale. But who actually owns all of these containers as they crisscross the oceans and highways? The answer is complicated and has evolved over time.
A Brief History of Shipping Containers
While the origins of using containers for shipping stretch back over a century, the ubiquitous standard containers we know today were pioneered in the 1950s by American businessman Malcolm McLean. At the time, longshoremen would manually load individual crates and pallets into ships – an incredibly laborious and inefficient process.
McLean realized that standardizing container sizes and developing cranes to move the boxes between ships and trucks would dramatically speed up loading, cut labor costs, and reduce theft. In 1956, his company SeaLand Industries launched the first vessel carrying standard containers between Newark and Houston. Given the immense benefits, international shipping lines quickly adopted containers and established standards.
The twenty-foot equivalent unit (TEU) container, first established in 1968, became the global standard. Today, there are only a handful of standard container sizes, enabling seamless intermodal transport. Since McLean’s innovations, container ships and seaports have been specifically designed around quickly moving these standardized boxes.
Leasing: The Norm for Containers
While shipping lines own some containers, the vast majority are leased from container leasing companies. The top players in this market include Triton International, Florens, Textainer, Seaco, and CAI International. There are also smaller regional leasing firms.
Leasing became the dominant model for a few key reasons:
- Cost – For shipping lines, leasing avoids huge capital outlays to purchase millions of containers. It’s more economical to rent them when needed.
- Flexibility – Leasing helps shipping companies rapidly adjust container capacity as trade volumes fluctuate. Lines can quickly take on more containers to meet demand spikes.
- Maintenance – Maintenance and repair are handled by the leasing companies rather than the shipping line. This includes repairs, painting, cleaning, etc.
- Balancing – Leasing firms manage moving empty containers to where they’re needed, which reduces imbalance issues for carriers.
Currently, leasing companies own around 80% of the world’s 27 million shipping containers. The rest are owned directly by shipping lines and other stakeholders.
Who Ships Your Container?
When you place an order from an overseas supplier and it arrives in a shipping container, who actually ships that box around the world?
While the container itself is almost certainly leased, the shipping line whose name is listed on the bill of lading actually transports your container between port terminals. For example:
- Maersk, MSC, CMA CGM – Operate massive fleets of container vessels and their own port terminals.
- Regional carriers like Evergreen Line, Yang Ming – Smaller fleets focused on specific trade lanes.
- Niche players like Matson, Zim Integrated Shipping – Specialize in certain geographic markets.
- FedEx, UPS, DHL – Offer container shipping services besides air and truck freight.
The leasing company simply owns the physical container and rents it out. The shipping line then provides international transportation via their container ships. Some key points:
- A given ship will carry boxes leased by many different companies.
- The line operating the ship will also utilize containers leased from many firms.
- Leasing helps lines keep capacity flexible across their fleet.
So in short, the shipping line transports your container, while a separate leasing company owns the container itself.
How Container Utilization Works
Given containers are leased, an important question is how do shipping lines utilize those rented boxes? There are some key dynamics that determine container movements:
- Head-haul versus backhaul routes – On major East-West trades like Asia to North America, full boxes flow on profitable head-haul routes. Empty boxes are repositioned via backhauls.
- Imbalances – Some regions import way more than they export, resulting in excess empty containers like U.S. to Asia.
- Peak season surges – Lines lease more boxes to meet high demand around holidays.
- Long term leases – Carriers will lease containers for multi-year periods to secure capacity.
- Short term leases – Additional containers can be rented for just a single voyage to meet demand spikes.
- Utilization metrics – Carriers aim to minimize empty container miles and keep each box filled as much as possible.
In essence, leasing enables lines to better match container capacity with trade flows and maximize utilization. The ebb and flow of world trade would be impossible to serve without this flexible, leased container model.
Maintenance and Transport Standards
To safely travel worldwide, shipping containers must meet stringent international standards. The International Organization for Standardization (ISO) sets standards for container construction, handling, stacking, and securing. Regulations also govern hazardous cargo transport.
Maintenance is a massive undertaking given the scale of containers across the globe. Leasing companies run regular inspection and repair programs to fix damage and keep boxes in circulation. Typical maintenance issues include:
- Corrosion
- Dents
- Floor repairs
- Door mechanisms
- Locking hardware
- Painting
The average reefer container travels over 200,000 miles annually, while dry vans average 120,000 miles. So wear and tear is a constant issue.
Additionally, the International Convention for Safe Containers provides policies on safely securing boxes aboard ships in passage. The Convention was drafted after accidents caused by improperly secured containers falling overboard.
Loss Prevention and Recovery
With millions of containers constantly moving across oceans and between ports, some are inevitably lost overboard or stolen. The World Shipping Council estimates 1,582 containers were lost at sea in 2016 – less than .006% of all boxes shipped. Security measures like sealing and tracking aim to prevent theft.
Recovery operations locate and retrieve lost containers. This often entails specialized remote operated underwater vehicles (ROVs) to find sunken boxes and divers to attach lifting straps. Lost containers can spell financial disaster for cargo owners if not insured properly.
Where Are Containers Made?
Every year, hundreds of thousands of new containers are manufactured to replenish the global fleet. Not surprisingly, the majority are produced in China due to its established steel and fabrication industries.
Chinese companies like CIMC, Singamas, and CXIC Group dominate container manufacturing and account for over 90% of production. Other major manufacturing hubs include South Korea, Vietnam, and India.
However, the last decade has seen some production move out of China to other Asian countries with lower labor costs such as Vietnam and Indonesia. But China maintains an overall lead in container manufacturing output.
Trends and Changes
Here are some evolving trends related to container ownership, leasing, and manufacturing:
- Larger ships and alliances – Cascading effects from megaships trickle down to leasing as carriers adjust strategies.
- Consolidation – Mergers among shipping lines and leasing firms aim to increase economies of scale.
- Overcapacity – An oversupply of containers has led to dropping lease rates and idled factory capacity.
- Digitization – Use of sensors, tracking, automation to better manage fleets and maintenance.
- Sustainability – Greater momentum toward reuse, refurbishment, and recycling of old containers.
While the shipping container system has remained fundamentally stable for decades, it continues adapting to match supply and demand. The exact ownership and utilization of containers keeps evolving along with global trade.
Conclusion
In summary, most shipping containers are owned by leasing companies instead of shipping lines. This arrangement allows maximum flexibility to adjust container capacity amid fluctuating trade volumes and economic shifts. While containers crisscross the seas, shipping companies focus on transport operations. Leasing firms handle owning the physical containers and maintaining them. Containers flow based on trade imbalances, seasonal demand shifts, and repositioning empty boxes. Standards enable boxes built anywhere to safely travel worldwide. Looking ahead, container ownership and usage will keep evolving alongside larger trends in global shipping.
