Whether a jar of honey can legally be sold as "honey", and whether it can carry an organic logo, depends on two separate kinds of rule. Compositional standards (Codex Alimentarius / EU Honey Directive, mirrored in UK food law) set hard limits on things like moisture content and hydroxymethylfurfural (HMF), a marker of overheating and ageing. Organic certification is a production-method rule: under EU/UK organic regulations, bees must forage within a radius that is essentially free of contamination sources such as intensively-sprayed crops, industrial sites or major roads — commonly a 3km foraging buffer, since that is roughly a honeybee's normal flight range.
A beekeeper can do everything right in the honey house and still fail organic certification purely because a neighbouring farmer sprays within the buffer zone — which is why UK organic beekeepers often need written assurances, or even soil/crop maps, from everyone farming land within the bees' flight range.
A 3D forage buffer zone around a working hive, paired with a honey jar whose fill and colour track moisture content and HMF, showing exactly which UK/EU/Codex thresholds a batch clears — and which one breaks certification.
Organic status depends on distance to contamination sources within a required forage buffer, while "genuine honey" labelling depends on compositional limits for moisture (ripeness) and HMF (heat/age damage) — two independent pass/fail checks.
Set the buffer radius your certifier requires and how close the nearest sprayed field or industrial site really is, then dial in a batch's measured moisture and HMF. Watch the buffer disc, honey jar and compliance badge respond live.
Because the "3km rule" is about the surrounding land, not the beekeeper's own practice, a certified-organic hive can lose its status overnight if a neighbouring farm starts spraying — with zero change in the apiary itself.
