Compliance is non-negotiable, especially for products intended for students or children. For the US market, products must comply with CPSIA (Consumer Product Safety Improvement Act) and ASTM D-4236 for labeling of art materials. For the EU, ensure adherence to EN71 (Safety of Toys) parts 1, 2, and 3, as well as REACH regulations. If your brand focuses on sustainability, look for FSC (Forest Stewardship Council) certification to guarantee that paper and wood components are sourced from responsibly managed forests.
