Operational view

SCIP, article, and compliance checks

2-benzotriazol-2-yl-4,6-di-tert-butylphenol (UV-320) 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.

Article duties

Check Candidate List threshold and SCIP relevance

Use this when the substance may sit in articles, components, or imported goods and you need to confirm communication and SCIP workflows.

 Alternatives

Open structurally nearby substances before substitution work starts

The alternatives route groups lower-pressure neighbors, regulatory peers, and same-class analogs so the team can compare candidates before a sourcing scramble.

 Source check

Verify the legal source before repeating the claim

Every summary should point back to the underlying authority surface. Use the source route when the exact notice, registry entry, or legal text matters.
