How can I set an expiration date on an SDS?

There's no built-in "expiration date" field, because expiry rules vary too much between organizations — instead, you define your own using a custom field:

1. In Manage SDS Library, open Personalized view → Custom fields, and click "+" to create a new field
2. Create a Date-type field named "Expiry Date" (see creating custom fields for exactly where that option lives)
3. The field is now available on every SDS in your library
4. Open any SDS's detail page, hover over the new Expiry Date field, and click the pencil icon that appears to set a date — the same hover-to-edit pattern used everywhere else (see editing the product name)

Once set, go to "All Our SDS" to list every SDS whose expiry date falls within a date range you choose — useful for a quarterly or annual compliance sweep.
