2. Core Specifications You’ll Need to Check
| Spec | Standard Value | Why It Matters to You |
|---|---|---|
| External Dimensions | 20 ft × 8 ft × 8.5 ft (L × W × H) | Determines whether the container fits through your gate or parking space. |
| Internal Dimensions | 19 ft × 7 ft × 7.9 ft | Dictates how much usable floor area you actually get. |
| Door Opening | 7 ft × 7.5 ft (standard swing‑door) | A wider door eases loading of bulky items and makes conversion projects simpler. |
| Weight | Tare weight ≈ 2,300 kg; Max payload ≈ 28,000 kg | Check your ground bearing capacity and the lifting equipment you’ll need. |
| ISO Rating | ISO 668 / ISO 10368 | Guarantees compatibility with global shipping and handling standards. |
| Ventilation | Usually 2–4 vent openings (optional) | Essential if you plan to store items that emit moisture or need airflow. |
| Insulation Options | None (stock) / Spray‑foam / Panel | Impacts temperature control for sensitive goods or living‑space conversions. |
Tip: Always ask the seller for a spec sheet that lists these numbers. Small variations (e.g., a higher roof) can dramatically affect your project.
3. Types of 20 ft Containers You Can Purchase
- Standard Dry Container – The most common; perfect for general cargo and storage.
- High‑Cube Container – 9 ft 6 in high, giving you an extra foot of vertical space. Ideal for tall equipment.

4. How to Evaluate the Right Seller
| Question to Ask | Why It Helps You |
|---|---|
| Is the container new, used, or refurbished? | New containers carry a premium but guarantee structural integrity. Used may have dents or rust that could affect durability. |
| Can you provide the ISO certification number? | Confirms compliance with international standards, which matters for resale or insurance. |
| What is the delivery method and cost? | Some sellers include transportation, while others charge per mile. Knowing this upfront prevents surprise fees. |
| Are there any warranties or service contracts? | A short warranty (e.g., 6 months) can give you time to spot hidden damage. |
| Do you offer customization services? | If you need windows, insulation, or a lock upgrade, buying from a seller who can modify the unit saves you time. |
Pro tip: Check online reviews and request photos of the actual container you’ll receive—not just stock images. A reputable seller will gladly share recent pictures and a video walkthrough.

7. Frequently Asked Questions (FAQ)
Q1: How long does it take to receive a 20 ft container after ordering?
A: For a new, stock container, delivery typically ranges from 7–14 business days if the seller is within the same country. International orders can take 3–6 weeks depending on customs clearance.
Q2: Do I need a permit to place a container on my property?
A: It varies by municipality. Many jurisdictions treat a container as a temporary structure, but if you plan a permanent installation or conversion into living space, you’ll need building permits, zoning approval, and possibly a utility hookup permit.
Q3: Can I stack 20 ft containers?
A: Yes—standard containers are designed for stacking up to three units when properly secured. However, only the bottom container should be placed on a solid foundation; the upper units rely on the container’s corner castings and twist‑locks.
Q4: What kind of lock is recommended for security?
A: A high‑security padlock (e.g., stainless steel, hardened steel shackle) combined with a bolt‑type door lock offers the best protection. Some owners install a digital keypad or biometric lock for added convenience.
Q5: How do I protect a container from rust in a salty coastal environment?
A: Look for containers with a Corten steel base and a marine‑grade powder coating. Applying a rust‑inhibiting primer and periodic touch‑up painting prolongs the life. Consider adding a ventilation system to reduce condensation.
Q6: Is it legal to convert a container into a tiny house?
A: Yes, provided you meet local building codes, obtain the necessary permits, and ensure the structure complies with fire safety, insulation, and plumbing standards. Many jurisdictions now have specific “Accessory Dwelling Unit (ADU)” guidelines that include container conversions.
Q7: What maintenance does a 20 ft container require?
A: Perform a quarterly inspection for rust, water ingress, and door seal integrity. Clean the exterior with mild detergent, touch‑up paint any chips, and lubricate hinges and locks. If you have insulation, check for mold or moisture buildup.
8. Quick‑Start List: 5 Things to Do Right After Your Container Arrives
- Level the Base – Use concrete pads, wooden sleepers, or steel jacks to ensure the container sits evenly.
- Seal the Gaps – Apply silicone or marine sealant around doors, windows, and any penetrations.
- Install Grounding – Connect a grounding rod to prevent static buildup, especially if you’ll run electrical wiring.
- Add Ventilation – Hang a small vent or install a solar‑powered fan to avoid condensation inside.
- Fit Security – Replace the stock lock with a high‑security lock and consider a CCTV camera for added peace of mind.
