An aerosol can is a pressure vessel and is normally managed as dangerous goods — sunscreen sprays and hairspray, for example, are commonly UN 1950 aerosols, classed as flammable gas or miscellaneous dangerous goods when they carry ethanol or hydrocarbon propellants. These goods usually require segregated storage away from ignition and heat sources, backed by fire management and emergency procedures.
The hotter the can, the higher the internal pressure. Prolonged heat or direct sunlight accelerates leakage, can deformation and content change, so the category normally calls for a light-protected, heat-free, temperature-controlled environment. Handling and stacking must also prevent tipping and crushing, so that dented cans, damaged nozzles or deformed cartons do not undermine packaging integrity.
Most spray products are beauty and personal-care goods: sunscreen sprays are special cosmetics requiring registration, while hydrating, setting and hair sprays are generally ordinary cosmetics under filing. Chinese labeling, batch numbers and shelf life still apply, and dispatch has to be recorded by batch with ledger-to-physical consistency. Whether we can take a given aerosol cargo follows from its MSDS, UN number and our actual zone conditions, checked item by item.
