When sourcing craft supplies, safety is the highest priority, especially for products intended for children. You must ensure that all materials are non-toxic and acid-free. For the US market, look for ASTM D-4236 labeling, which confirms that the art materials have been evaluated by a toxicologist. For the EU, EN71 certification is mandatory to ensure physical and chemical safety. Additionally, check for small parts warnings on items like beads or buttons to prevent choking hazards for younger demographics.
