The data each company owns is not shared with the network unless you grant permission. There are network alliance programs where partners can opt in to participate, such as "Trending Products". If you would like to receive "Trending Products" data and reports from data collected across the entire network, you would need to grant ChemSource the ability to collect and share the PRODUCT NAME and QTY requested with the network (NO prospect/customer info).
Example: let's assume your business is located in Georgia and someone requests an inquiry on Caustic Soda, the following data would be available to the network: 1000 lbs of Caustic Soda, CAS# 1310-73-2 was requested on "xx/xx/2017" in the SouthEast region
Again, each company can control exactly what data is shared. If you do not share any data (you have this option) you will not be able to participate in certain network alliance programs like "Trending Products".
