Enhanced Quality Program & Products

The Enhanced Quality program for raw materials provides clearly defined quality levels and the appropriate solutions for your evolving regulatory needs. Each Sigma-Aldrich/SAFC product is characterized by assigning the individual product’s quality traits across a four-level value system: Standard, Premium, Elite and GMP.

Our Enhanced Quality profile for Sigma-Aldrich/SAFC products demonstrates the different levels of quality, documentation and supply chain traceability that we can provide to biopharmaceutical and diagnostic manufacturers.

These tiers are set up to reflect the various levels of product quality and documentation required by customers. With Enhanced Quality products, your raw material quality standards are defined based on your application and supply chain requirements, matching the right quality level with your risk mitigation needs. Product lists for each quality level are available here:

For customers who need high-quality raw materials for biopharmaceutical and pharmaceutical manufacturing, SAFC has created the PharmaGrade product line. PharmaGrade products have a fully documented production history, with consistent and controlled processes, compliant to GMP or Elite grade.

Change Control Notification (CCN) Program

An integral part of SAFC’s Enhanced Quality approach is our Change Control Notification (CCN) program, which links our partners with the Sigma-Aldrich/SAFC change management system. The CCN program provides customers with written notification of specified changes to their products. The level of change control notification of your product is determined by the quality level in which it has been classified. If you wish to participate in the program, please complete a CCN request.
