The SDS should include all SAFETY relevant information/ingredients for whatever jurisdiction. If the local area doesn't really care if it's hexane or pentane from a safety perspective, they'll likely just be lumped together behind a generic name/cas number.
Hopefully if you sum enough of those SDS across different jurisdictions, the actual list of ingredients will come out. Though I guess it isn't that simple.
It's absolutely not a BOM to reproduce a product.
