Acrylonitrile under REACH

C3H3N · 丙烯腈

Status: Restricted. Acrylonitrile is fully registered under REACH at the highest tonnage band (>1,000,000 tonnes/year). **Distinguishing pattern: closes butadiene batch 27 + ammonia batch 37 + propylene chains via SOHIO ammoxidation (propylene + NH3 + air with Bi-Mo catalyst, ~90 percent of global acrylonitrile production per public sources, INEOS / Asahi Kasei licensors; verified against https://en.wikipedia.org/wiki/Ammoxidation) + Carc 1B (H350) + Muta 2 + Acute Tox. 3 + Skin Sens 1 + IARC classification for acrylonitrile is being re-evaluated in IARC Monograph Volume 136 (Talc and Acrylonitrile, published 2025; verify current Group classification at https://monographs.iarc.who.int/monographs-available/ before relying); prior dataset citation of "Monograph 121" was an error - Volume 121 covers Styrene, Styrene-7,8-oxide and Quinoline, NOT acrylonitrile + REACH SVHC candidate-list inclusion since 13 January 2010 (NOT on REACH Annex XIV authorisation list; the SVHC candidate list and Annex XIV are different lists, candidate listing is the precursor step but acrylonitrile has not been recommended for Annex XIV inclusion) + ABS / SAN / acrylic fibre / adiponitrile / NBR primary downstream chains + completes ABS triangle with styrene batch 25 + butadiene batch 27.** Reg (EC) 1272/2008 harmonised: Flam. Liq. 2 + Carc 1B + Muta 2 + Acute Tox. 3 oral / dermal / inhalation + STOT SE 3 + Skin Sens 1 + Skin Irrit. 2 + Eye Irrit. 2 + Aquatic Chronic 2. REACH SVHC candidate listing since 13 January 2010 (sources: ECHA SVHC candidate list, https://echa.europa.eu/candidate-list-table). NOT on REACH Annex XIV authorisation list (verify against the ECHA Annex XIV list at https://echa.europa.eu/authorisation-list before relying). Verify current EU anti-dumping measures on Chinese-origin acrylonitrile against the EU Official Journal before invoicing; at time of audit (May 2026) no active definitive AD measure on bare acrylonitrile monomer is confirmed (note: thermoplastic ABS from Korea has been subject to a separate EU AD investigation distinct from acrylonitrile monomer trade).

Acrylonitrile carries **heavy cumulative regulatory burden** at the workplace and downstream-article-notification level: Carc 1B + Muta 2 + Acute Tox. 3 + Skin Sens 1 + IARC classification under re-evaluation in Monograph Volume 136 (2025); verify current Group at https://monographs.iarc.who.int/monographs-available/ + REACH SVHC candidate-list inclusion since 13 January 2010 (NOT on Annex XIV authorisation list; common confusion is conflating SVHC candidate listing with Annex XIV listing). At time of audit (May 2026) no active definitive EU anti-dumping measure on bare acrylonitrile monomer is confirmed; verify current AD measures against the EU Official Journal at https://eur-lex.europa.eu/ before invoicing. **Closes butadiene batch 27 + ammonia batch 37 + propylene chains via SOHIO ammoxidation**; completes ABS triangle with styrene batch 25 + butadiene batch 27. Major Chinese producers (verify against current market reports): Sinopec (Anqing, Shanghai SECCO, Yangzi, Maoming), Wanhua Chemical Yantai. China dominates global acrylonitrile capacity (~30%, ~3-4 Mt/yr per ICIS / S&P 2024 estimates). End-use: ABS / SAN (~30%), acrylic fibre (~25%), adiponitrile / nylon-66 (~20%), NBR (~10%, alongside butadiene batch 27), other (~15%).

  • **IARC: acrylonitrile re-evaluated in Monograph Volume 136 (Talc and Acrylonitrile, 2025); prior Monograph Volume 71 (1999) had assessed acrylonitrile at Group 2B. Verify current Group classification against https://monographs.iarc.who.int/list-of-classifications/ before relying. Note: Volume 121 covers Styrene, Styrene-7,8-oxide and Quinoline, NOT acrylonitrile**
  • REACH SVHC candidate-list inclusion since 13 January 2010 (CMR Cat 1B basis); ECHA SVHC list https://echa.europa.eu/candidate-list-table
  • NOT on REACH Annex XIV (Authorisation list); verified against ECHA Annex XIV list at https://echa.europa.eu/authorisation-list. SVHC candidate-list inclusion is the upstream step in the authorisation pathway, but acrylonitrile has not been recommended for Annex XIV listing
  • NOT subject to Drug Precursors or Explosives Precursors scheduling
  • ADR / RID transport classification: Class 3 (flammable liquid) + Class 6.1 toxic, UN 1093, Packing Group I

Restrictions and conditions of use

  • REACH SVHC candidate-list inclusion since 13 January 2010: any article placed on the EU market containing >0.1% w/w acrylonitrile triggers REACH Article 33 communication-to-recipient obligations and SCIP database notification (where applicable to article suppliers)
  • NOT on REACH Annex XIV Authorisation list (verified against ECHA list); no authorisation requirement applies to use of acrylonitrile
  • Verify current EU anti-dumping measures on Chinese-origin acrylonitrile against the EU Official Journal at https://eur-lex.europa.eu/ before invoicing; at time of audit (May 2026) no active definitive AD measure on bare acrylonitrile monomer is confirmed
  • Carbon Border Adjustment Mechanism (CBAM): NOT in CBAM Phase 1 scope
  • EU Reg 10/2011 food-contact: acrylonitrile specific migration limit (SML "ND" non-detectable, verify against current Reg 10/2011 Annex I)
  • EU Industrial Emissions Directive (IED) requires permitting for production sites
  • EU Directive 2004/37/EC Carcinogens and Mutagens at Work: occupational exposure limit applies

Importer obligations

A non-EU producer cannot register directly under REACH. The EU importer of record must hold a registration or rely on an Only Representative (OR). The dominant practitioner overhead is the substantial workplace and occupational-exposure compliance burden driven by the Carc 1B + Muta 2 + Acute Tox. 3 + Skin Sens 1 classification stack, plus REACH Article 33 downstream-recipient communication obligations triggered by SVHC candidate-list inclusion since January 2010. Verify current EU anti-dumping measures on Chinese-origin acrylonitrile against the EU Official Journal before invoicing; at time of audit (May 2026) no active definitive AD measure on bare acrylonitrile monomer is confirmed. Major Chinese producers (verify against current ICIS / S&P market reports): Sinopec (Anqing, Shanghai SECCO, Yangzi, Maoming), Wanhua Chemical Yantai. EU domestic producers (verify against current company sources): Ineos Köln, Ineos Lillo Belgium, Repsol Tarragona Spain, TotalEnergies Lavera France.

Required documents

  • REACH registration number on the EU side (registrant or OR-appointed)
  • REACH Article 33 SVHC communication to downstream recipients for any article placed on EU market containing >0.1% w/w acrylonitrile (SVHC candidate-list inclusion since January 2010)
  • Safety Data Sheet (SDS) compliant with REACH Annex II reflecting H225 / H301 / H311 / H315 / H317 / H319 / H331 / H335 / H341 / H350 / H411 classification
  • CLP-compliant labelling with GHS02 + GHS06 + GHS08 + GHS09 pictograms and DANGER signal word
  • Customs entry with HS code 2926.10 (acrylonitrile, verify against current EU TARIC nomenclature)
  • ADR consignment note for transport (Class 3 + Class 6.1, UN 1093, PG I)
  • Producer-specific anti-dumping margin documentation (where active EU AD measure applies; verify EU Official Journal before each shipment)

Common compliance traps

The pitfalls that have bitten importers on this lane in the past. None of these is theoretical.

  • REACH SVHC candidate-list inclusion since 13 January 2010 drives Article 33 downstream-recipient communication and SCIP database article notification (where applicable to article suppliers >0.1% w/w)
  • NOT on REACH Annex XIV (Authorisation list); the SVHC candidate list and Annex XIV are different lists, and a common confusion is treating candidate-list inclusion as if it were authorisation listing
  • Verify current EU anti-dumping measures on Chinese-origin acrylonitrile against the EU Official Journal before invoicing; at time of audit no active definitive AD measure on bare acrylonitrile monomer is confirmed
  • Carc 1B + Muta 2 + Acute Tox. 3 + Skin Sens 1 drives substantial workplace exposure-control overhead under Directive 2004/37/EC
  • Closes butadiene batch 27 + ammonia batch 37 + propylene chains via SOHIO ammoxidation (propylene + NH3 + air with Bi-Mo catalyst); completes ABS triangle with styrene batch 25 + butadiene batch 27
  • Major Chinese producers (verify against current market reports): Sinopec (Anqing, Shanghai SECCO, Yangzi, Maoming), Wanhua Chemical Yantai. China dominates global acrylonitrile capacity (~30%, ~3-4 Mt/yr per ICIS / S&P 2024 estimates)
  • Production: propylene + ammonia + air SOHIO catalytic ammoxidation (~99% globally; INEOS / Asahi Kasei licensors)
  • End-use mix: ABS / SAN (~30%, alongside styrene batch 25 + butadiene batch 27), acrylic fibre (~25%), adiponitrile / nylon-66 (~20%), nitrile rubber NBR (~10%, alongside butadiene batch 27), other (~15%)
