Shipping Containers for Sale: New & Used Conex Boxes

A shipping container is a standardized steel box, also called a conex box, cargo container, or sea container, built to ISO specifications so it can be stacked, locked, and shipped anywhere in the world. At StackCrateCo we sell new and used shipping containers for sale in every standard size and condition, shipped from our yard in the St. Louis metro (Sauget, IL 62206) with next-business-day loadout and delivery across the continental United States. Whether you need secure on-site storage, a base unit for a build, or a specialized container, this is the hub for our full lineup, with every category linked below.

Shipping containers earn their popularity through sheer toughness and value. The same corten-steel construction engineered to survive ocean transit stacked nine-high makes a storage unit that is weatherproof, pest-proof, lockable, and effectively maintenance-free for decades. Drop one on level ground and you have instant, secure square footage with no foundation, no permit for basic storage in most areas, and no construction.

Shop Shipping Containers by Size

Container size is the first decision, because it sets your capacity and your delivery footprint. We stock every standard length:

• 10ft containers — compact, urban-friendly storage, about half a single-car garage.
• 20ft containers — the most popular all-purpose size, roughly a one-car garage of secure space.
• 40ft containers — maximum standard capacity for high-volume storage and projects.
• 45ft containers — extra length for the largest storage needs.
• High cube containers — a foot of added interior height in 20ft, 40ft, and 45ft, ideal for tall loads, racking, and conversions.

Shop Shipping Containers by Type

Beyond standard dry storage, we carry specialized containers for specific jobs. Browse the dedicated categories for each:

• Refrigerated containers (reefers) — insulated, temperature-controlled units for cold and frozen storage.
• Container homes — finished and build-ready units for residential living.
• Container cabins — compact dwellings for off-grid retreats and hunting camps.
• Container accessories — locks, ramps, shelving, vents, and parts to outfit any unit.

New vs. Used Shipping Containers

Choosing condition is the second key decision, and it comes down to budget versus appearance and lifespan.

New (One-Trip) Containers

A new or “one-trip” container has made a single cargo voyage from the factory, so it arrives in near-pristine condition with minimal wear, clean interiors, and the longest service life. One-trip units are the right choice for conversions, customer-facing sites, food-grade use, and anyone who wants the best-looking, longest-lasting box.

Used (Cargo-Worthy and Wind-and-Watertight) Containers

Used containers deliver the same secure steel storage at a lower price. A cargo-worthy unit is certified structurally sound for shipping, while a wind-and-watertight (WWT) unit is guaranteed sealed against the elements for storage. We grade every used container honestly so you know its age and condition before you buy, and we never sell a leaky box as watertight.

What People Use Shipping Containers For

• On-site and business storage: inventory, equipment, tools, seasonal stock, and records.
• Construction: secure job-site storage and tool cribs that move with the project.
• Agriculture: equipment, feed, and supply storage that resists weather and pests.
• Conversions: offices, workshops, homes, cabins, bars, and pop-up retail.
• Residential: garage overflow, workshop space, and storm-resistant storage.

Shipping Container Delivery

Most shipping containers are delivered on a tilt-bed truck that slides the unit gently onto the ground, so you need clear, level access roughly twice the container’s length for the truck to position and unload. We confirm site access before dispatch and walk you through placement so delivery day goes smoothly. Tell us your address and the unit you want, and we will quote it delivered with no hidden fees.

Shipping Container FAQs

How much does a shipping container cost?

Shipping container prices depend on size, condition, and your location relative to our yard. Used 10ft and 20ft units are the most affordable, new (one-trip) and 40ft or 45ft units cost more, and specialized units like reefers are priced separately. Browse the categories for current pricing or call (312) 998-4030 for a delivered quote.

What is the difference between a conex box and a shipping container?

There is no real difference. “Conex box,” “cargo container,” and “sea container” are all common names for the same ISO-standard steel shipping container. The terms are used interchangeably in the industry.

Do I need a permit to put a shipping container on my property?

For basic, ground-level storage many areas do not require a permit, but rules vary by city and county and some have specific container ordinances. Converting a container into a dwelling or office almost always requires permits. Always confirm with your local zoning or building department before purchase.

What size shipping container should I buy?

A 20ft container, roughly the space of a one-car garage, suits most general storage needs and is the most popular size. Choose a 10ft for tight spaces, a 40ft or 45ft for high-volume storage, or a high cube when you need extra interior height for tall loads or a conversion.

How are shipping containers delivered?

Standard containers are delivered by tilt-bed truck that lowers the unit to the ground, requiring clear, level access about twice the container’s length. We confirm access before delivery and ship from our St. Louis metro yard to most of the continental US. Call (312) 998-4030 with your address for a delivered quote.
