At Kelioil group, shipping sample retention is a rigorous and crucial process. Whenever products are ready for shipment, staff members will select representative samples for each batch and each product type. For instance, for different types of cementing additives such as fluid loss additives, retarders, and dispersants, an appropriate amount of samples is taken to ensure that the samples can comprehensively reflect the characteristics of the entire batch of products.
Once the samples are taken, they are immediately labeled with special tags, clearly indicating the product model, batch number, sample - taking date, expected expiration date, and the customer information corresponding to the batch of products. After that, these retained samples are uniformly placed on dedicated sample - storage racks and arranged in an orderly manner according to the sample - taking date and product type, facilitating subsequent search and management.
During the 12 month sample retention period, at regular intervals, professionals will conduct visual inspections and spot checks of key indicators on the retained samples. Once a problem is detected, the corresponding batch of products can be traced back promptly.
When customers have any questions or feedback regarding the products, these sample - retention records can quickly come into play, helping Kelioil accurately identify and troubleshoot problems, and providing customers with precise solutions, thus fulfilling our commitment to quality and customers with practical actions.
