Safety is the highest priority for school supplies as they are used by children. For the US market, products must comply with CPSIA (Consumer Product Safety Improvement Act), which strictly limits lead and phthalate content. For the EU market, EN71 (Safety of Toys) certification is mandatory for items like crayons and paints, while REACH compliance ensures no harmful chemicals are present. Always verify that writing instruments meet ISO 11540 standards regarding ventilated caps to prevent choking hazards.
