What it means	Australia's largest organic certifier, accredited under the Australian National Standard for Organic and Bio-Dynamic Produce. The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.	The certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.	The word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.

Guarantees	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare and biodynamic-compatible production options.	All organic standards PLUS biodynamic preparations and whole-farm planning. Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.	Nothing. It is not a certification and there is no body verifying anything.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
Does NOT	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.	Doesn't mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced. Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
