Does the United States have a unified and single set of rules or regulations that govern the actions of domestic companies?

Question

Will there ever be a single set of international rules governing multinational companies? And in what way are United States businesses demanding socially responsible behavior from their international suppliers? 

Answer 1

No.  We have the Constitution, laws passed by Congress and Regulations written by a myriad of Executive organizations such as the FCC, ICC, FDA and many others.  There are bound to be conflicts within such a huge body of laws.  Then there is a similar set of State groups that create rules and regulations.

Never is a very long time.  I see no reason to expect to see a single set of international rules governing multinational companies in the foreseeable future.

US businesses often talk about demanding socially responsible behavior from their international suppliers, but they rarely back up these demands with significant penalties for violators.  So the question becomes what is the worth of a demand that is not vigorously enforced?
