Sources

Verify where the data came from

Use this when you need to audit provenance before trusting a claim.

Action prompts

Fast compliance and screening routes

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.

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.
