According to the statement "Coca Cola suppliers", "Coca Cola HBC requires critical suppliers to gain certification to the following standards:
ISO 9001 (quality)
ISO 14001 (environment)
OHSAS 18001 (health and safety).
Ingredient and packaging suppliers must also achieve certification to FSSC 22000 certification for food safety and the Global Food Safety Initiative (GFSI)."
It means that any organisations which meet these requirements can be their suppliers and partners. Coca Cola as an international band, it needs suppliers and partners from different areas and regions.
