Local Economy of Shipping Containers in St. Louis
The shipping container industry in St. Louis has a long history, dating back to the mid-20th century when the city served as a major transportation hub for goods being shipped across the country. Today, the industry is still going strong, with a number of local companies involved in everything from shipping and intermodal transportation to storage and repurposing. Major players in the industry include the Terminal Railroad Association of St. Louis, Intermodal Cartage Company, and ContainerPort Group.
The industry provides jobs for thousands of local residents and contributes to the local tax base, helping fund a variety of local services and infrastructure projects. Additionally, the industry has spurred the growth of other sectors in the area, such as logistics and manufacturing.
Looking ahead, the future looks bright for the shipping container industry in St. Louis, with the continued growth of e-commerce driving demand for fast and efficient shipping options. There is also growing interest in the creative repurposing of Conex boxes for shipping container home developments, container apartments, modern retail spaces, and art installations.
Using Cargo containers for self storage in St. Louis
Portable storage containers for sale in St. Louis are becoming a highly popular option for self-storage. They offer several benefits over traditional storage units, including superior security, cost-effectiveness, versatility, convenience, and eco-friendliness—making them perfect for local initiatives like the Jeffersonville redevelopment projects.
Made of durable, heavy-duty corrugated steel, our cargo containers are designed to withstand harsh Midwestern weather conditions and deter theft, making them the ultimate secure storage option. They are also incredibly affordable; buying a shipping container is a one-time expense with no recurring monthly rental fees or hidden costs (though we do offer rent-to-own shipping container options if you prefer).
Cargo containers come in various sizes and can be easily customized with roll-up doors, shelving, and lighting to fit individual storage needs. They can also be conveniently delivered right to your property, giving you 24/7 access to your stored belongings. Using cargo containers for self-storage is an eco-friendly choice, as they are completely recyclable and reduce the need for new, permanent construction. Overall, steel cargo containers provide an excellent, heavy-duty alternative for St. Louis residents and businesses in need of extra storage space.
Customer Success Story
Chesterfield Design Co. Chesterfield, MO
Needing secure on-site storage during a multi-phase renovation in Chesterfield (just west of St. Louis), the client purchased a 40‑ft wind‑and‑watertight container from US Conex’s St. Louis depot. Delivered in 7 business days, the conex box arrived clean and dry. The construction team inspected the unit on-site and paid after delivery, then used it to safeguard tools and materials through a sudden spring storm. The result? Zero damage, smoother logistics, and project completion two days ahead of schedule.

Frequently Asked Questions
What types of shipping containers do you sell in St. Louis?
US Conex sells new and used conex containers, shipping containers, storage containers, cargo containers, and sea containers in the St. Louis, MO area. All units are built from heavy-duty CORTEN anti-corrosive steel to withstand Missouri's humid summers and severe weather. Available in three grades:
-
New One-Trip — made one journey from the factory to the US, essentially brand new
-
Used Cargo Worthy (CW) — certified for ocean export, structurally sound
-
Used Wind & Watertight (WWT) — fully weatherproof, most affordable option
Available in 20ft standard, 40ft standard, and 40ft High Cube sizes. See current pricing in the table above.
What is the difference between a WWT and a CW container?
WWT (Wind & Watertight) containers are weatherproof and structurally sound — guaranteed no holes or leaks — but are not certified for ocean transport. They are the most affordable and popular option for on-site storage, residential use, and commercial projects across Missouri.
CW (Cargo Worthy) containers are certified for international ocean freight. They meet stricter structural standards and are the right choice if you need to export goods, require certified containers for shipping, or want the highest-quality used unit for a modification project.
Both grades are inspected before delivery and backed by our 25-year structural and leak warranty.
Can I rent a portable storage container in St. Louis?
Yes. If you need temporary storage, US Conex offers portable storage containers for rent across the St. Louis metro with flexible terms from 1 to 24 months — no credit check and no security deposit required. We also offer a rent-to-own option where monthly payments go toward purchasing the unit outright. This is ideal for construction contractors, riverfront commercial businesses needing secure inventory storage, or residents requiring temporary space.
To get started, fill out our rental application on the Rent page and we'll review it within two business days.
Which cities do you deliver storage containers to from St. Louis?
From our St. Louis-area depots, we deliver shipping containers across Missouri and the surrounding 200-mile radius, including:
-
Metro St. Louis — Chesterfield, St. Charles, Florissant, and Belleville (IL)
-
Other Missouri Hubs — Columbia, Springfield, and Cape Girardeau
-
Southern Illinois — Carbondale and Mount Vernon
We leverage major interstates like I-70, I-55, and I-44 to ensure fast, affordable tilt-bed delivery directly to your property.
Do I need a permit for a shipping container in St. Louis, MO?
Permit requirements in St. Louis depend on your intended use and duration:
-
Temporary on-site storage: Generally no permit required for active, permitted construction sites.
-
Permanent placement or structural modifications: Contact the City of St. Louis Building Division at (314) 622-3313. (Note: If you are outside city limits in St. Louis County, you will need to contact the county permit office instead).
-
Zoning: Be sure to check local zoning laws, as residential zones and commercial/industrial zones often have different allowances for container placement.
We recommend confirming local requirements before ordering a Missouri shipping container for permanent installation.
Can I inspect the conex box before I pay?
Depot visits are not allowed for safety and liability reasons, but our pay-after-delivery option provides complete peace of mind. The container is delivered to your St. Louis-area property, you inspect it on-site, and only then do you complete payment. If the unit does not match the agreed grade or condition, you are not obligated to accept it.
Every container is also covered by our 25-year structural and leak warranty from the date of delivery.
Can your containers handle Missouri's weather?
Absolutely. All of our containers are built from CORTEN anti-corrosive steel, which is specifically engineered to resist rust in humid, snowy, and rainy conditions. WWT and CW units are guaranteed watertight — no holes or leaks — so your contents stay completely dry through Missouri's severe spring storms and winter weather.
How do I get a price for delivery to my address?
Enter your ZIP code in the quote tool on this page. Our system will identify your nearest St. Louis-area depot, calculate the delivery cost, and provide a total delivered price. A container specialist will then contact you within 3 business days to confirm availability and walk you through the order process. There is no upfront payment required to place an order.
