Manufacturing expiration dating policy

This commitment is demonstrated by the establishment of programs to monitor, preserve and protect the quality of our products.

The only date shown on the certificate of analysis will be the Quality Release date.

For these products there is no stated expiration or recommended retest date, and the shelf life has not been determined.

For those materials where shelf life information is a requirement, expiration and retest periods are available at the batch level.

IVD products that are expiration dated will have the expiration date found on the product labels.


The provisions of this subchapter apply to each institution of higher education, as that term is defined by Section 61.003 of this code, including each public junior college to the extent possible.

If extended, a new Date Retested and Recommended Retest Date will be published on the Certificate of Analysis.

If Sigma-Aldrich does not retest a lot in question, we recommend that customers evaluate the product to ensure that it still matches their needed specifications.
