📦 What Exactly Is a 30‑Foot Container?
A 30‑foot container (often called a 30ft high‑cube or 30ft dry cargo container) is a steel box that conforms to international ISO standards. It’s slightly longer than the classic 20‑ft box (which measures 20 ft × 8 ft × 8.5 ft) but shorter than the 40‑ft version, giving you a tidy middle ground.
| Dimension | Metric (mm) | Imperial (ft) |
|---|---|---|
| External Length | 9 600 mm | 30 ft |
| External Width | 2 438 mm | 8 ft |
| External Height | 2 896 mm (high‑cube) | 9.5 ft |
| Internal Length | 9 050 mm | 29.7 ft |
| Internal Width | 2 352 mm | 7.7 ft |
| Internal Height | 2 698 mm | 8.86 ft |
| Door Opening (Width × Height) | 2 280 mm × 2 350 mm | 7.48 ft × 7.71 ft |
| Cubic Capacity | ~ 57 m³ | ~ 2 020 ft³ |
| Maximum Tare Weight | 2 500 kg | 5 511 lb |
| Maximum Gross Weight | 30 480 kg | 67 200 lb |
| Payload (Net Load) | 27 980 kg | 61 689 lb |
Quick Takeaway: A 30‑ft container gives you roughly 57 m³ of usable volume—about 30 % more space than a 20‑ft unit while remaining easier to maneuver than a 40‑ft box.
💡 Why Choose a 30‑Foot Container? (Top 7 Reasons)
- Balanced Size – Enough room for bulkier inventory, yet still fits on most standard pallets and forklifts.
- Cost‑Effective – Typically 20‑30 % cheaper than a 40‑ft container, both in purchase price and shipping fees.

❓ Frequently Asked Questions (FAQ)
1️⃣ Do I need a special permit to place a 30‑ft container on my property?
Most residential zones don’t require a permit for a single container, but local ordinances vary. Check with your city’s planning department. If you plan to use it as a dwelling, zoning and building codes often apply.
2️⃣ How long does delivery typically take?
Domestic shipments usually arrive within 5‑10 business days after the order is confirmed. International deliveries can take 2‑4 weeks depending on customs clearance.
3️⃣ Can a 30‑ft container be stacked on top of a 20‑ft container?
Yes, as long as the combined weight stays within the stacking limits specified on the CSC plate (usually 9 000 kg per container). Use a certified crane and proper twist‑locks.
4️⃣ What’s the difference between a “dry cargo” and a “high‑cube” container?
Both are designed for general goods, but a high‑cube container offers an extra 6 inches of internal height, providing more vertical space—great for tall items.
5️⃣ Are containers safe for storing hazardous materials?
Standard dry containers are not rated for hazardous materials unless they have a UN‑rated certification. For chemicals, you’ll need a certified dangerous goods container.
6️⃣ How do I protect the interior from condensation?
Install a vapor barrier (polyethylene sheet) along walls and ceiling, and consider a small dehumidifier if you’ll store moisture‑sensitive items.
7️⃣ Can I paint the exterior myself?
Absolutely! Use a marine‑grade epoxy primer followed by a high‑performance enamel. Make sure the paint is approved for steel and suitable for your climate.
8️⃣ How do I secure the container against theft?
Standard lock sets are a good start, but consider adding:
- Padlock with hardened steel shackle
- Electronic keypad or RFID lock
- CCTV camera
- Alarm system (optional)
9️⃣ What’s the typical lifespan of a steel container?
If well‑maintained, a container can last 30‑40 years. Corrosion, extreme weather, and heavy misuse shorten that timeline.
🔟 Is financing available for container purchases?
Many dealers partner with leasing companies to offer monthly payment plans (often 12–36 months). Check with the seller for rates and credit requirements.
