The oil is a flammable liquid and oxidises with heat, light and air, so transport and storage are built around those two risks. RequirementsSealed, correctly labelled packs, away from heat, sparks and open flame.Cool (< 25 °C), dry, ventilated warehouse, away from polluting odours.Protect from light; amber glass or lined drums are preferred.Keep headspace minimal; nitrogen blanketing is available for long storage.Stock rotation is first-in-first-out and the COA carries the production date and storage note.

Shelf life is 36 months from production when the pack is sealed and stored correctly. StorageSealed, in the original pack, away from light.Cool and dry: below 25 °C is the practical target.Ventilated store, away from strong odours and away from ignition sources.Refrigeration extends life for long-term holds; cold haze clears on warming.Oxidation is the main failure mode: once opened, use the contents in a reasonable period or re-test. Re-test before the end of shelf life.
