The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.	Germany's national organic mark, owned by the Federal Ministry of Food and Agriculture.

Imported organic foods must be re-certified under the Chinese standard — overseas certifications alone are not accepted for the 有机 label.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	Same standard as the EU Leaf — not stricter.
