Bis(tributyltin) oxide (TBTO) is currently surfaced as candidate list substance in the EU.

This page turns the imported framework rows into task prompts. It is meant to answer the operational question after the status question, especially when teams need SCIP, article, procurement, or substitution guidance.

The fastest way to use it is: confirm the active framework, scan the first operational checks, then open the legal source only if the claim needs escalation or formal sign-off.
