What this hub helps organize
The sections separate legal concepts, product and material context, supply-chain evidence, and common customer requests. That makes it easier to identify which requirement a report, declaration, BOM, or questionnaire should answer.
Substance list and product context
Confirm whether the customer is asking about a listed substance, a product material, or a warning requirement. These are not the same question.
Check first in practice
- Substance and product
- California-market context
- Customer document requirement
Evidence and practical response
Supplier declarations, material information, or analytical results may all be useful, but they need to support the product and current customer question. Define the gap before arranging further work.
