If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

1. How can one locate a Certificate of Analysis (COA) for a NIST standard? 2. Are lot numbers assigned to NIST Standards?
1. How can one locate a Certificate of Analysis (COA) for a NIST standard?
2. Are lot numbers assigned to NIST Standards?1 answer-
1) You can find certificates and other product information on NIST’s website: https://shop.nist.gov/
Remove "NIST" prefix from our product number when searching on the NIST website (e.g. “136F” instead of “NIST136F”)
2) No, NIST does not have lot numbers, and instead the product number is changed.
NIST lots are denoted in their product numbers. Take NIST136F for example. The current lot is “F”, whereas NIST136E came before it. When NIST releases a new lot for Product 136, we will create a new product number, NIST136G, and so on.

What does the "3110" lot number signify in the system?
1 answer-
The "3110" lot number is used as a placeholder in the system when an actual lot number is not available.
In this particular instance, the way NIST numbers their lots does not align well with the lot numbering convention in SAP. NIST incorporates the lot identification within their product numbers. For example, for the product NIST136F, the lot is identified as "F", succeeding the previous lot "E". As new lots are released by NIST, a new product number is assigned, such as NIST136G for the subsequent lot, and the pattern continues accordingly.Helpful?
