Scope definition and its implications

"My company is a chemical manufacturing company producing products for a wide variety of industries out of a single location, A customer of ours in the cosmetics sector has requested we achieve both the ISO 9001 certification and the EFFCI GMP. My question is are we able to limit the scope to the production of the specific chemistries we are producing for this customer or does it have to be inclusive of all products produced at the facility?”
