The five bases
NISNut-in-shell as harvested, at its stated moisture content.
DNISDry nut-in-shell at a stated moisture content. Most trade statistics use this. Our presentation standard is DNIS at 3.5%.
kernelShelled kernel weight — roughly a third of in-shell weight, which is why mixed-basis comparisons mislead by design.
not_applicable · unknownFX rates and areas have no basis; a source that states none is stored as unknown — permanently, until the source itself corrects it. We never infer a basis to make two numbers agree.
Moisture normalization
normalized = value × (100 − m.c.reported) / (100 − 3.5)Standard dry-matter adjustment: the same physical crop, restated at 3.5% moisture. Applied only when the source states both basis and moisture.
Kernel equivalent
Kernel-equivalent figures require a recovery ratio with three parts: the number, the base it applies to, and a citable source. Ours is ratified at the Australian published Sound Kernel Recovery — it is versioned below and stamped immutably onto every figure it normalizes, so a historical chart can always be traced to the exact ratio that produced it.

Changing a ratio is a reviewed, versioned change. Figures normalized under an earlier version keep that version’s stamp forever — a historical chart can always be traced to exactly the ratio that produced it.
