What is Covered Under our 25-Year Warranty?
At US Conex, we stand by the quality and durability of our inventory. As an Authorized Partner of Used Conex LLC, every container we sell is backed by an industry-leading 25-Year Warranty to protect your investment and guarantee secure storage.
25-Year Structural Guarantee: We cover any significant structural defects that would impair the container’s ability to serve its intended purpose. This comprehensive coverage protects the core integrity of the unit, including the frame, walls, roof, and flooring.
25-Year Leak Warranty: We guarantee your container will keep your belongings safe from the elements. In the event of leaks or holes caused by rust over time, we will provide an industrial-grade, non-rusting repair material. It sets in just 5 minutes and permanently restores the watertight seal.
How the Pay-After-Delivery Process Works?
We make buying a shipping container risk-free. With our Pay-After-Delivery option, you don't pay a dime until our driver arrives at your property with your container. Here is exactly how the process works:
Zero Upfront Deposit: We do not require any money down. Your full payment is due only upon delivery, allowing you to inspect the container first.
Quick Verification: Once you submit your application and sales agreement, our team will call you within 3 business days to verify your details and officially process your order.
Eligibility Requirements:
Delivery Only: Because our depots operate strictly as storage facilities without on-site sales offices, this payment option is only available if you hire US Conex to deliver the container to you.
Service Area: Your delivery location must be within 300 miles of a US Conex depot.
Order Size: This option applies to orders of a single shipping container. If you need multiple units, alternative payment methods are required.
Delivery Timeline: You can expect your container to arrive within an average of 10 to 15 business days (up to 20 days in certain areas based on driver availability).

Frequently Asked Questions
* What is a conex box? A conex box — short for "Container Express" — is a standardized intermodal steel shipping container.
Today, conex containers are used worldwide for storage, shipping, and construction. The terms conex, connex, sea can, cargo container, and shipping container all refer to the same type of unit. If you've been searching "what is a conex container" or "what is a connex box", you're looking for exactly what we sell.
* What is the difference between conex and connex? Nothing at all — conex or connex are simply two spellings of the same word. Whether you search for conex container, connex container, connex box for sale, or conex box for sale, you'll find the same product at US Conex.

*What is a one-trip shipping container? A one-trip shipping container (also called 1-trip, container one trip, or single-use shipping container) has made exactly one journey from the factory to the US. These are essentially brand-new units and are the cleanest new shipping containers for sale available.
*What is a WWT container vs a CW container? WWT (Wind & Watertight) containers are weatherproof but not approved for ocean freight — the most affordable used shipping containers. CW (Cargo Worthy) containers are certified for ocean transport — more durable and slightly higher priced. Both are excellent choices depending on your use. See our Container Sizes & Grades page for full details.

US Conex offers some of the most affordable shipping containers in the US market. Discount shipping containers may be available at certain depot locations depending on inventory — contact us to ask about current deals.
*What does "conex storage" mean? Conex storage simply means using a conex container as a storage unit — whether on a job site, at home, or for a business.
