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 federal Canadian organic standard, mandatory on any agricultural product sold across provincial borders or imported as 'organic'.	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 US Department of Agriculture's national organic standard. The green-and-white seal is the legal mark for any food sold as 'organic' in the United States.

Guarantees	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare and biodynamic-compatible production options.	≥95% organic ingredients (single-ingredient products: 100%). No synthetic pesticides, no GMOs, no irradiation. Annual third-party certification under the Canada Organic Regime.	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.	At least 95% of ingredients are certified organic (the '100% Organic' variant requires every ingredient). No synthetic pesticides, no synthetic fertilizers, no GMOs, no sewage sludge, no irradiation. Annual on-site inspection by a USDA-accredited certifier. Residue testing on at least 5% of certified operations each year.
Does NOT	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	Provincial sales-only operations are not legally required to carry it (though many do voluntarily).	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 certify nutrition, taste, or animal welfare specifically (separate marks like AWA cover welfare). Doesn't guarantee local production — a 'USDA Organic' product can be grown anywhere with an accredited inspector.
