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.

It's absolutely not a BOM to reproduce a product.

I'd say a BOM is more like the list of ingredients (or inventory) of what's in a product.

Depending on what the product is, this may still be a long way from the full "recipe" (or method) to recreate the product.

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.
