1. The Business Case for Buying Used
| Benefit | What it Means for You | Typical Savings |
|---|---|---|
| Lower upfront cost | You can acquire a 20‑ft container for a fraction of the price of a new one. | 40‑70 % off the new‑container price |
| Faster delivery | Many used containers are already stocked locally, so you can have them on site within days, not weeks. | 2‑4 weeks saved |
| Reduced depreciation | A used container has already taken the steepest part of its value drop, so its resale value stays relatively stable. | Up‑to‑30 % higher resale after 5 years |
| Eco‑friendly | Re‑using steel reduces the demand for fresh metal production, cutting CO₂ emissions. | Roughly 1 ton CO₂ saved per 40‑ft container |
| Customization flexibility | Many sellers offer conversion services (insulation, windows, doors) at lower rates than new‑build specialists. | 20‑35 % cheaper than building from scratch |
Bottom line: If you’re looking to stretch every dollar while demonstrating a commitment to sustainability, second‑hand containers tick both boxes.
2. Types of Containers You’ll Find on the Market
| Size | External Dimensions (L × W × H) | Typical Interior Volume | Common Uses |
|---|---|---|---|
| 10‑ft | 9.6 m × 2.4 m × 2.6 m | ~12 m³ | Small workshops, tool lockers, pop‑up retail kiosks |
| 20‑ft | 6.1 m × 2.4 m × 2.6 m | ~28 m³ | Storage rooms, portable offices, shipping containers for cargo |
| 40‑ft | 12.2 m × 2.4 m × 2.6 m | ~56 m³ | Large warehouses, modular classrooms, mobile clinics |
| High‑Cube (HC) | Same footprint as standard but 2.9 m high | +~10 m³ extra | Refrigerated units, data‑center racks, high‑bay storage |
Specialty Variants
- Cold‑Chain Containers – Insulated and fitted with refrigeration units (ideal for food‑grade or medical supplies).
- Modified‑Fit (M‑Fit) – Pre‑installed shelving, lighting, electrical wiring, or plumbing.
- Flat‑Rack Containers – No side walls, just a sturdy frame; great for oversized cargo.
When you browse listings, make sure the container’s type aligns with the specific function you have in mind. A 20‑ft standard box can be turned into a tiny office with a few modifications, but a high‑cube refrigerated unit is the smarter choice for a pop‑up grocery kiosk that needs temperature control.
3. What to Inspect Before You Buy
Even though a second‑hand container looks simple, there are hidden pitfalls that can cost you time and money later. Use the following inspection checklist as a quick reference on a site visit or when reviewing photos from a seller.
| Checklist Item | Why It Matters | How to Verify |
|---|---|---|
| Exterior Corrosion | Rust can spread, weakening the structure. | Look for flaking paint, pitting, and rust streaks; tap the steel – a solid sound indicates good thickness. |
| Roof Condition | Leaks are the most common issue. | Check for dents, rust patches, and any water stains inside the container. |
| Floor Integrity | A warped or damaged floor compromises load capacity. | Walk across; feel for flex. Look for cracks, rust-through, or missing floor panels. |
| Door Alignment & Seals | Misaligned doors cause security and weather‑tightness problems. | Open/close doors; they should glide smoothly and seal evenly. |
| Structural Deformations | Bends or twists affect stacking and transport. | Measure diagonal dimensions; they should be equal on opposite corners. |
| Certification & History | ISO 668 standards guarantee dimensions; previous use can indicate wear. | Ask for a Container Identification Number (CIN) and request the CSC (Container Safety Certificate). |
| Modifications | Unapproved cuts or welds may weaken the shell. | Inspect any added windows, vents, or internal partitions. |
| Load Rating | Over‑loading can cause collapse. | Verify the container’s Maximum Gross Weight (MGW) and ensure it meets your intended load. |
Quick Tip
If you’re buying online, ask the seller for high‑resolution photos of the corners, roof, and door hinges, and request a recent inspection report. Reputable dealers will gladly provide this documentation.
4. How to Choose the Right Supplier
Not every seller is created equal. Here’s a short list of criteria you can use to narrow down your options:
- Reputation & Reviews – Look for verified customer feedback on platforms like Trustpilot, Google Business, or industry forums.
- Inventory Transparency – A good dealer maintains an online catalog with detailed specs, photos, and CIN numbers.
- After‑Sales Support – Does the supplier offer delivery, off‑loading equipment, and optional conversion services?
- Warranty or Return Policy – Even used goods can come with limited guarantees (e.g., 30‑day structural warranty).
- Location Proximity – Shipping a 20‑ft container from overseas can add $2,000–$4,000 in freight. Local suppliers often reduce costs dramatically.

| Buying a container without a valid CIN | May not meet local regulations; risk of fines. | Verify the CIN and cross‑check with the International Container Bureau (ICB) database. |
| Assuming all containers are the same | Incompatible dimensions for stacking or transport. | Check ISO 668 specifications; high‑cube vs. standard height matters. |
| Ignoring delivery logistics | Unexpected crane rental or site access issues. | Conduct a site survey and confirm loading/unloading capabilities before purchase. |
| Skipping warranty | No recourse if container arrives damaged. | Choose a seller offering at least a short‑term warranty or return window. |
7. Frequently Asked Questions (FAQ)
Q1: How long do second‑hand containers typically last?
A: If maintained properly, a well‑constructed steel container can serve 20–30 years, even more when stored under shelter. Regular rust treatment and roof inspections extend life.
Q2: Are there any legal restrictions on using a used container as a building?
A: Yes. Local building codes may require permits, especially if you install windows, doors, or modify the structure. Check with your municipality’s planning department and ensure the container meets fire‑rating standards.
Q3: What is the difference between a “dry” container and a “reefer”?
A: A dry container is an uninsulated, standard steel box used for general cargo. A “reefer” (refrigerated container) includes insulation, a cooling unit, and a temperature monitoring system.
Q4: Can I finance a used container?
A: Some equipment lenders and leasing companies offer financing for pre‑owned containers, often with lower interest rates than new‑box loans. Compare offers and read the fine print regarding residual values.
Q5: How do I transport a container to a remote site without road access?
A: Options include rail-to-truck transfers, barge shipping (if near a waterway), or using a track‑mounted crane for off‑road delivery. Discuss logistics with the seller early to avoid surprises.
Q6: Is it possible to insulate a used container yourself?
A: Absolutely. Polyurethane spray foam, rigid board, or blanket insulation can be installed on the interior. Just ensure the container is clean, dry, and free of rust before applying any material.
Q7: What are the typical dimensions of a 20‑ft high‑cube container?
A: Exterior: 6.058 m × 2.438 m × 2.896 m; Interior height: 2.69 m (≈ 8 ft 10 in). This extra height provides roughly 10 m³ more usable volume than the standard 20‑ft model.
