For children, have our student crayons 12 color ribbon pen holder crayons passed the relevant safety certification?

As items that come into direct contact with children and may enter the mouth or contact the skin, the safety of crayon products for children is extremely important. Safety certification is an important means to ensure that crayon products comply with relevant safety standards and regulations, and is also an important guarantee for protecting children's health and safety.
For children's crayon products, the safety certifications that may be involved mainly include the EU's EN71 standard, the US CPC certification, and other international or regional safety certifications. The EN71 standard is the EU's safety standard for toy products. Crayons, as children's drawing tools, are regarded as a type of toy in the EU, so they must comply with the EN71 standard. The EN71 standard includes multiple parts, among which the main ones related to crayon products are EN71-3 (migration test of specific elements) and EN71-9 (organic compound test). These standards strictly limit the migratable metal elements (such as lead, cadmium, etc.), polycyclic aromatic hydrocarbons and other harmful substances in crayons. If the crayon product passes the EN71 standard test, it means that the content of harmful substances in the product meets the EU safety requirements and can be sold in the EU market.
CPC certification is part of the U.S. Children's Product Safety Improvement Act (CPSIA), which requires all children's products sold in the United States to pass CPC certification. CPC certification requires that crayon products must comply with standards such as ASTM F963-17 (mechanical physics and combustion tests), 16 CFR 1501 (small parts test), and eight heavy metal dissolution tests, total lead and phthalate tests, etc. These tests are designed to ensure the physical safety, chemical safety and combustion safety of crayon products. If a crayon product passes CPC certification, it means that the product meets the safety requirements of the U.S. market and can be sold in the U.S. market.
In addition to safety certifications in the EU and the United States, crayon products can also consider passing safety certifications in other countries or regions, such as China's 3C certification and Japan's ST mark certification. These certifications will help improve the competitiveness of products in the global market.
