The Amazon website in the United States requires all children's toys and children's products to provide a Children's Product Certificate (CPC), which is similar to a COC certificate. When launching product categories related to children on Amazon America, including toys, baby products, etc., a CPC certificate will be required, otherwise they will not be sold. Although called a "certificate," CPC certification is not issued by any official agency and does not need to be filed with government departments. Essentially, it is a "guarantee letter" drafted and fully responsible by the manufacturer/importer, stating that their products comply with all applicable children's product safety regulations and other laws and regulations in the United States.
