United States here, and potentially also involving two states, New York and Vermont.
If a business is a vendor that sells goods to the federal government (as a GSA awarded contractor) and also sells goods to state procurement agencies (New York - Office of General Services, or OGS; and in Vermont its the Office of Purchasing & Contracting), they have to maintain inventory data and regularly submit updates to the agency they have an award with.
In a similar vein to how HIPAA regulates businesses who maintain health data, and PCI regulates businesses that collect payment information from consumers, are there any similar regulations that govern what such GSA/OGS/OPC vendors can do with their inventory data?
