Current EU status

Regulatory snapshot for Hexabromocyclododecane

Hexabromocyclododecane is currently surfaced as authorisation list (annex xiv) in the EU.

The current imported view anchors this substance in REACH and CandidateList. The live rationale focuses on PBT (Article 57d), and this page is designed for fast status checks before deeper source review.

Searchers usually land here for the chemical name, CAS number, abbreviation HBCDD, and the question of whether the substance is tied to SVHC, REACH, POPs, or SCIP-style compliance work.

Why this page matters

Hexabromocyclododecane works well as a landing page because the exact name, HBCDD abbreviation, and insulation-focused use context all point to the same high-intent research problem.

In chem-data the substance appears in flame-retardant, insulation, and plastics routes. That makes it a practical dossier for building-material and polymer screening, not just a generic chemical entry.

Searchers usually want to connect HBCDD identity with Annex XIV, Candidate List history, insulation use, and a clear path into obligation or substitution routes.

What teams usually verify first

  • Is the current issue tied to insulation, construction, or polymer portfolios where HBCDD appears in legacy materials?
  • Does the substance need Annex XIV or authorisation-style review rather than a simple watchlist check?
  • Which neighboring flame-retardant substances should be opened before a material transition plan is proposed?

What to do next

Use the right route for status, SCIP, and source questions

Status

Current legal state, Candidate List signals, and source-backed rationale

Go here for the framework answer block, listed dates, reasons, and the imported basis for the current EU status.

 Obligations

Who needs to act, what to check, and whether SCIP matters

Use this when the question is operational: SCIP, article communication, threshold review, portfolio screening, or substitute work.

 Why monitored

Why this substance is monitored in the EU

Use this when you want the hazard or legal basis behind the current status, not just the status label itself.

 Alternatives

Potential substitutes and nearby molecules

Use this to branch into lower-pressure neighbors, same-class analogs, and candidate-list peers.

 Changes

What changed over time

Use this when you want the timeline, not just the current state.

 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.

 Use pathway

Check whether current use depends on an authorisation-style pathway

REACH-facing rows should trigger a direct review of legal basis, named use, and whether internal approvals still match the imported status.

 Portfolio review

Screen affected product families and formulations

The use profile suggests this substance can appear in materials portfolios where one listing can ripple across multiple SKUs, suppliers, or component bills.

 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.
