What is a Container Loading Inspection (CLS)?

A Container Loading Inspection (or Loading Supervision) verifies container condition, carton counts, loading method, and sealing at the time of stuffing — typically at the factory or CFS before the container departs for the port.

When should I book a CLS in India?

Book a CLS for any high-value FCL shipment, mixed-PO containers, fragile or oversized goods, or first-time suppliers. It is the only point at which you can verify quantity and condition before the seal is applied.

What does a CLS cost in India?

A typical CLS at an Indian factory or CFS costs $250–$350 per man-day. Most 20'/40' containers are loaded within one shift, so cost is one man-day.

What is the difference between CLS and FRI?

FRI (Final Random Inspection) checks product quality on finished goods before they are packed. CLS happens after FRI — it checks container condition, carton count, and loading method as the goods are stuffed into the container.

Why does the seal number matter?

The seal number is recorded on the Bill of Lading and is the legal proof that the container was not opened between origin and destination. An inspector should witness sealing and photograph the seal with its number visible.
