When sourcing craft supplies, you must prioritize material safety and chemical compliance. For the US market, ensure products meet ASTM D-4236 (Standard Practice for Labeling Art Materials for Chronic Health Hazards) and CPSIA requirements if the crafts are intended for children. For the EU, compliance with EN71 (Toy Safety Standard) and REACH regulations is mandatory to ensure the absence of lead, phthalates, and other toxic substances. Always request MSDS (Material Safety Data Sheets) for adhesives, paints, and resins.
