Abstract: Methods and systems for tracking inventory. A method of tracking a container of a chemical includes labeling the container with a machine readable code that includes data which uniquely identifies the container and/or its contents. Historical data concerning the shipment and/or use of the container or its contents, or any other data specific to the container may be stored in a database that associates data with the specific container based on the unique identifier. An inventory management system may then automatically track a specific container by scanning the machine readable code to identify the specific container, and then accessing the database to both store and retrieve data related to the scanned container and/or its contents.
