On the flip side, it would be nice for suppliers to know their products are not toxic in the first place, rather than to just catch it after the harm is done.

On the flip side, it would be nice for suppliers to know their products are not toxic in the first place, rather than to just catch it after the harm is done. This will act as a deterrent to catch those knowingly selling toxic products. But if lab testing isn't in the reach of suppliers, then how can they know if it's toxic free? That said, I think a safety net is valuable, whether Amazon or government. It would be nice to see innovation to bring the cost of testing down so it's accessible to everyone.
