Control Shipping Level

The Control Shipping Level (CLS) is an inspection process, carried out by a third party company, on the premises of automotive suppliers, aimed at checking and preventing materials and products that do not conform from being shipped. Shipment of the product only occurs once a CLS done by the RINA Services Team has been passed.

In detail, a level 2 CLS checks that products conform in terms of specific, pre-defined checking cycles, whereas a level 3 CLS combines the level 2 activities with suitable corrective actions, in order to remove the non-conformity factors at the root.


  • Guaranteeing the quality of the end product.
  • Guaranteeing better production efficiency, by effective risk prevention and management.
  • Guaranteeing customer satisfaction.


A CLS 2 includes a series of checks, carried out on 100% of the supply over a pre-defined period, aimed at checking the quality of the product put out, and preventing it reaching the assembly line with anomalies that have already been picked up, are serious, or are repeated.


CLS 3 activities become necessary when the supplier, faced with anomalies picked up during a CLS 2, shows that they do not have the technical and organisational skills to resolve the anomalies. In addition to the checks included in a CLS 2, the third party company checks application of suitable corrective and improvement actions.
