Status: Restricted. Hydrogen peroxide is fully registered under REACH. **Distinguishing pattern: anthraquinone process (~99% globally, with periodic regeneration) + pulp + paper bleaching primary downstream (~50%) + HPPO PO chain (batch 29, ~10% and growing) + caprolactam HPPO chain (batch 14, ~10% in new plants) + Wanhua Chemical Yantai HPPO process PO units (Penglai Industrial Park ~600,000 t/yr POCHP per public sources; verify against company materials before relying on the "world-leading" framing, Solvay also operates large HPPO H2O2 mega-plants serving multiple PO sites) (closes PO batch 29 HPPO chain) + Skin Corr. 1A (>70% conc) + Ox. Liq. 1 (>70% conc) + EU Explosives Precursors Reg 2019/1148 (H2O2 >12% restricted for retail) + Solvay-Evonik-licensed-process (NEW combined).** Reg (EC) 1272/2008 harmonised: Ox. Liq. 1 (>70% conc) + Skin Corr. 1A (>70% conc) + Acute Tox. 4 oral / inhalation. NOT SVHC. NOT Annex XIV.

Hydrogen peroxide is fully REACH-registered with **Ox. Liq. 1 + Skin Corr. 1A (>70%) + Acute Tox. 4 hazard profile**. **Closes PO batch 29 HPPO chain** + caprolactam batch 14 HPPO chain (new plants). NOT SVHC, NOT Annex XIV. NO active EU AD case. NOT in CBAM Phase 1. **EU Explosives Precursors Reg 2019/1148** (H2O2 >12% conc restricted). Major Chinese producers: Solvay China Zhenjiang JV, **Wanhua Chemical Yantai (HPPO integrated capacity)**, Hubei Yihua, Anhui Jinhe, Sinopec. China dominates global H2O2 capacity (~50%, ~5-6 Mt/yr 100% basis). Production: anthraquinone process. End-use: pulp + paper bleaching (~50%), HPPO PO chain (~10%, growing), caprolactam HPPO chain (~10% in new plants), wastewater + chemical (~15%), textile + sterilisation + electronics-grade (~10%), other (~5%).

Listing and threshold

Substance Hydrogen peroxide (H2O2) (CAS 7722-84-1), H2O2
Regime EU Regulation (EC) No 1907/2006: Registration, Evaluation, Authorisation and Restriction of Chemicals
Jurisdiction European Union (EU-27 plus EEA: Iceland, Liechtenstein, Norway)
Status Restricted
Tonnage threshold Registration required for any importer or manufacturer placing >1 t/year on the EU market

Classifications under this regime

  • Harmonised CLP classification: Ox. Liq. 1 (H271, "may cause fire or explosion; strong oxidiser", for >70% conc), Skin Corr. 1A (H314, ">70% conc"), Acute Tox. 4 oral / inhalation (H302 / H332), Eye Dam. 1 (H318)
  • Signal word: DANGER (>70% conc); WARNING (lower concentrations)
  • GHS pictograms: GHS03 (oxidiser flame over circle), GHS05 (corrosion), GHS07 (exclamation mark)
  • IARC: hydrogen peroxide classified IARC Group 3 (not classifiable as to carcinogenicity to humans) per Monograph Volume 71 (1999) (verify the current classification and Monograph volume against https://monographs.iarc.who.int/list-of-classifications before relying)
  • **EU Explosives Precursors Regulation (EU) 2019/1148**: H2O2 >12% conc restricted for retail / private use; >35% requires authorisation (verify against https://eur-lex.europa.eu/eli/reg/2019/1148/oj before relying)
  • ADR / RID transport classification: Class 5.1 (oxidising substance), UN 2014 (>20-60% conc) / UN 2015 (>60% conc) / UN 2984 (8-20% conc)
  • EU food additive E 240 NOT permitted (banned)

Restrictions and conditions of use

  • NOT on REACH Annex XIV (Authorisation list)
  • NOT classified as SVHC
  • **EU Explosives Precursors Regulation (EU) 2019/1148**: H2O2 >12% conc restricted; >35% requires authorisation (verify against https://eur-lex.europa.eu/eli/reg/2019/1148/oj before relying)
  • NO active EU AD case on Chinese-origin H2O2 currently (verify against https://trade.ec.europa.eu/access-to-markets/en/content/trade-defence-investigations before relying)
  • NOT in CBAM Phase 1 scope
  • EU Reg 10/2011 food-contact: H2O2 permitted as plastic food-contact processing aid

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-facing layer is **EU Explosives Precursors Reg 2019/1148 + Skin Corr. 1A + Ox. Liq. 1 hazard + corrosion-resistant tankage**. Major Chinese producers: Solvay China Zhenjiang JV, Wanhua Chemical Yantai (HPPO integrated), Hubei Yihua, Anhui Jinhe, Sinopec.

Required documents

  • REACH registration number on the EU side (registrant or OR-appointed)
  • Safety Data Sheet (SDS) compliant with REACH Annex II reflecting H271 / H302 / H314 / H318 / H332 classification
  • CLP-compliant labelling with GHS03 + GHS05 + GHS07 pictograms
  • Customs entry with HS code 284700 (hydrogen peroxide)
  • ADR consignment note for transport (Class 5.1, UN 2014 / 2015 / 2984)
  • **Explosives Precursors operator + customer documentation** per Reg 2019/1148

Common compliance traps

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

  • **EU Explosives Precursors Reg 2019/1148** (H2O2 >12% conc restricted for retail; >35% requires authorisation)
  • **Closes PO batch 29 HPPO chain** + caprolactam batch 14 HPPO chain (new plants)
  • Skin Corr. 1A + Ox. Liq. 1 (>70%) drives engineered controls + corrosion-resistant tankage
  • NOT SVHC, NOT Annex XIV
  • NO active EU AD case on Chinese H2O2 currently
  • NOT in CBAM Phase 1
  • Major Chinese producers: Solvay China Zhenjiang JV, **Wanhua Chemical Yantai (HPPO integrated capacity for PO batch 29 + new caprolactam batch 14 plants)**, Hubei Yihua, Anhui Jinhe, Sinopec. China dominates global H2O2 capacity (~50%, ~5-6 Mt/yr 100% basis)
  • Production: anthraquinone process (~99% globally; Solvay + Evonik licensors)
  • End-use mix: pulp + paper bleaching (~50%, structurally largest end-use), HPPO PO chain (batch 29, ~10%, growing rapidly), caprolactam HPPO chain (batch 14, ~10% in new plants), wastewater treatment + chemical synthesis (~15%), textile bleaching + sterilisation + electronics-grade (~10%), other (~5%)
  • Concentration tiers: 35% (most common industrial-grade), 50%, 60%, 70%, 90%, 98% (rocket-fuel grade)
