Due to their nature as pressurized or explosive-adjacent items, compliance is critical. For the US market, products must adhere to CPSC (Consumer Product Safety Commission) guidelines and ASTM F963 for toy safety. For the EU, CE Marking and compliance with the Pyrotechnic Articles Directive (2013/29/EU) are required, even for non-pyrotechnic versions. Always request MSDS (Material Safety Data Sheet) for the contents, especially for smoke bombs or metallic foils, to ensure they are non-toxic and non-staining.
