Most companies working with nanoclay understand the first layer of compliance: the substance has to be on the relevant chemical inventory. Bentonite is. Montmorillonite is. That box is usually ticked before anyone thinks hard about it.

The second layer is the one that catches people. A growing set of nano-specific obligations sits on top of ordinary chemical law, and they are triggered not by what the substance is but by what form it is in. The uncomfortable part is that “nano enough to trigger reporting” has no single definition. It has at least four, and they don’t agree.
