The issue here is the level for both ceramics and surface coatings. The risk is flaking of its small particles, its dust. It tends to be an inhalation risk less than an ingestion risk, because toys are designed and our toy standards are such that they can't fit in a child's mouth. So with children's jewellery, we're worried that it often ends up in the child's mouth. They suck on it and there's a risk of ingestion. So the exposure route is different. That's why we feel uncomfortable using the surface coating standard for children's jewellery. It's very specific to the risk.
We're not alone and we won't try to answer this question alone. We're working actively with the U.S., the EU, and other jurisdictions, so if we're pushed to have to develop regulations on this, we will have a safe level.
