What to expect from Sea Container grades

Why do Sea containers have blemishes?

Even single-trip units have hauled a loaded run from the factory in Asia through cranes, ships, trucks and depots, so the odd scrape or dent is normal. Used units have repeated that journey for years, picking up extra scars that never affect structural strength.

  • Yes! Sea Container prices can fluctuate with market conditions, meaning you might resell for as much—or even more—than you paid. They’re not just a smart solution for storage and transport, but also a potential asset that can hold or increase in value over time.
