Compliance is critical for safety and legal entry into markets. For the US, products must meet ASTM F2417 (Standard Specification for Candle Fire Safety) and CPSC labeling requirements. For the EU, adherence to REACH regulations and CLP (Classification, Labelling and Packaging) is mandatory, requiring specific warning pictograms and allergen declarations. Always request MSDS (Material Safety Data Sheets) and IFRA (International Fragrance Association) Certificates from the supplier to ensure chemical safety.
