This category covers very different physical forms: liquid, emulsified, paste and powdered flavourings differ in their sensitivity to temperature and humidity, while aroma isolates and essential oils are highly concentrated volatile components. The category is generally expected to be stored cool and dark, at a stable temperature and moderate humidity, and separated from strongly odorous goods to reduce loss of aroma and cross-tainting.
Essential oils are especially sensitive to light and oxygen: UV and heat accelerate oxidation and evaporation, most noticeably in monoterpene-rich citrus oils, while oil-bearing materials can turn rancid over time. Industry practice emphasises sealed containers, minimal headspace, light protection and a stable temperature, with inert-gas blanking used for bulk storage. These are the general requirements for the category — each one can be checked against our actual conditions.
Container and packaging compatibility is a distinctive part of this category: some essential oils act as solvents, so prolonged contact with certain soft plastics carries a risk of plasticiser migration and aroma absorption. Glass, aluminium or containers with a documented compatibility assessment are generally recommended. This is a packaging-selection and handling requirement, confirmed against each cargo's SDS, stability data and the condition of the packaging on arrival.
