# Olive oil, crude

## 1. Scope and Applicability

This rule covers unrefined olive oil obtained directly from olive fruit by mechanical or other physical extraction at an olive mill. The foreground starts with received olives at the mill gate and ends with bulk oil after separation and any physical settling, centrifugation or filtration performed before transfer. Declare whether the output is edible virgin grade or lampante grade; this PCR does not assign a grade from inventory data. Refining, extraction of oil from pomace, blending with refined oil, retail packaging, orchard cultivation and downstream use are outside this foreground. These distinctions follow `cxs33-2015`, `ioc-trade-standard-2026` and `turkey-olive-lca-2023`.
