Sea container inspection to ISO 1496-1 and CSC certification standards

Sea container inspection to ISO 1496-1 and CSC certification standards

A sea container needs to be more than just functional — it must be structurally sound and compliant with international standards. In both maritime and land transport, the ISO 1496-1 standard and CSC certification (Container Safety Convention) are essential for safety and reliability. At CBOX, we carry out inspections and repairs strictly according to these globally recognised technical requirements. 

What is ISO 1496-1?

ISO 1496-1 sets out detailed specifications for the strength, durability and dimensional tolerances of standard shipping containers (such as 20ft and 40ft units). The testing requirements include: 

• Stack load tests of up to 192,000 kg 
• Corner casting stress tests to ensure safe stacking and lifting 
• Floor load tests to confirm the structure can handle forklifts and pallet jacks 
• Weather resistance testing, including watertightness and exposure to temperature fluctuations 

Containers that meet these standards are suitable for ongoing use in international logistics. 

CSC inspection: required for international shipping 

Any container used in international trade must have a valid CSC plate. This certification confirms that the container meets structural safety requirements for sea and land transport. A CSC inspection typically checks for: 

• Corrosion or wear on key load-bearing elements
• Damage to corner castings 
• Proper operation of doors, locks and hinges 
• Condition of welds and frame alignment
  
  

At CBOX, we provide CSC inspections, re-certifications, and carry out any necessary repairs to bring containers back to standard.

How CBOX performs container inspections

Our skilled technicians are trained to assess containers in line with ISO and CSC standards. We use advanced tools and inspection methods, including: 

• Ultrasonic thickness testing on steel wall panels 
• Leak testing using smoke or pressurised air 
• Precision frame and alignment checks 
• Authorised documentation to support resale or re-certification
  
  

All repairs are done using ISO-compliant materials and welding methods to ensure your container is fit for purpose and fully approved for international use.
