What is container loading supervision (CLS)?

On my previous article I have explained pre-shipment inspection in detail, by replying the fundamental questions in regards to pre-shipment inspection.

We have covered following questions so far:
  • When should the pre-shipment inspection be conducted? 
  • What are the benefits of a pre-shipment inspection? 
  • How much does it cost to have a pre-shipment inspection?
  • How does a pre-shipment inspection work?
But one of the main questions is left unanswered. 

How can we as an importer make sure that the inspected goods will be shipped to us? 

How can we as an importer make sure that the loading process is fine and the package as per conditions stated on the sales contract?

One of the correct answer of above questions is Container Loading Supervision (CLS) and today I would like to explain this inspection type in detail.
