Compliance is non-negotiable in the fragrance industry. For the US market, ensure products meet ASTM F2417 (Standard Specification for Candle Fire Safety) and CPSC labeling requirements. For the EU, products must comply with CLP Regulation (Classification, Labelling and Packaging), which requires specific hazard pictograms and allergen declarations on the packaging. If you are sourcing electronic diffusers, they must carry CE, RoHS, or UL certifications to guarantee electrical safety and electromagnetic compatibility.
