Being kind of new at this and not having much experience to fall back on I'll try to wade into the subject at hand
Bottom line (as far as the EMS is concerned, remeber there may be other issues)
If MSDS's are identified as "system" required documentation they have to be controlled, if not, they don't.
If you have Title V permits and MSDS's are required in performing mass balance calculations (normally it's going to be CPDS's that are required, but there are always exceptions) then they are system documents requiring control.
It's up to each organization to "define" its own documentation requirements beyond the minimum specified in 4.4.4 and throughout the standard when it references "records" and other stuff.
Now if an organization is doing something real crazy, like using MSDS's to serve as the "characterization" of hazardous wastes, they they also become system documents requiring whatever controls have been established.
The only time an MSDS is not an "external" document is when the orgaization is the "originating source" or "writer" of it because it produces the material requiring the generation of the MSDS I/A/W US OSHA statutes.
The MSDS is primarily an occupational safety related document that has been adopted for use in other areas like environmental compliance and consumer product safety under certain specified conditions by the regulatory agency involved.
Then again, what would I know about it?

That is my take as well, but I wanted to see what the consensus was of the group. I also wanted to see if anyone would say that MSDS “had” to be part of the EMS. If they thought that, I was interested in their reasoning.
) promoted to ISO coordinator, instead of Quality coordinator. Now I find myself in the midst of an attempt to implement 14001. I had previously told the manager of environmental dept. my thoughts on what he needed to perform implementation, giving him all kinds of advise/examples and offering my help. He rejected every suggestion I gave him so I just bowed out and let him hang himself. Now my boss, who is his boss too, has demanded that I "take control of the implementation and "put my fingerprints all over it" " Oh, boy.
