Formaldehyde under REACH

CH2O · 甲醛

Status: Restricted. Formaldehyde is fully registered under REACH at the highest tonnage band (>1,000,000 tonnes/year) but **carries the heaviest regulatory burden in the dataset by hazard classification**. **Distinguishing pattern: most hazardous substance in the dataset combining Carc 1B + Muta 2 + Acute Tox. 3 + Skin Corr. 1B + Skin Sens 1 + IARC Group 1.** Reg (EU) 605/2014 (the 6th ATP to CLP, published 6 June 2014) harmonised the Carcinogen Cat 1B + Mutagen Cat 2 classification for formaldehyde; the regulation entered into force in April 2015 with mandatory compliance from 1 January 2016 (verify exact transition end-date against EUR-Lex CELEX 32014R0605 before relying on either). **Annex XVII Restriction 77 (Reg (EU) 2023/1464)** sets EU-wide formaldehyde-emission limits from articles (wood-based panels and other articles) effective 6 August 2026 (vehicle interiors 6 August 2027): emission ceiling 0.062 mg/m^3 for furniture and wood-based articles, 0.080 mg/m^3 for other articles, verified against https://eur-lex.europa.eu/eli/reg_impl/2023/1464. **Annex XVII Restriction 72 (Reg (EU) 2018/1513)** sets a 75 mg/kg formaldehyde concentration limit in textile articles in skin contact (clothing, accessories, footwear), with a temporary 300 mg/kg derogation for jackets, coats and upholstery that ran 1 November 2020 to 1 November 2023, verified against https://eur-lex.europa.eu/eli/reg/2018/1513. NOT on Annex XIV authorisation list (kept on restricted-not-authorised pathway). NOT SVHC (kept off SVHC despite Carc 1B because of essential industrial use). NO active EU AD case on Chinese-origin formaldehyde currently confirmed; verify against EU Official Journal before invoicing.

Formaldehyde carries the **heaviest regulatory burden in the dataset by hazard classification**: Carc 1B + Muta 2 + Acute Tox. 3 + Skin Corr. 1B + Skin Sens 1 + IARC Group 1 (since 2006). The most-imminent practitioner watch-item is **Annex XVII Restriction 77 effective 6 August 2026**: EU-wide formaldehyde-emission limits from articles (wood-based panels, upholstered furniture, mattresses, textiles, leather articles) will reshape EU lane economics from August 2026. Restriction 77 puts pressure all the way back through the supply chain to formaldehyde-resin producers and ultimately to Chinese-origin formaldehyde producers. NOT on SVHC despite Carc 1B (kept off because of essential industrial use). NO active EU AD case. Major Chinese producers: Sinopec Beijing + Sinopec Yanshan, Wansheng Chemical Anhui, Wanhua Chemical Yantai, Liuyang Chemical Industrial Park (Hunan), Henan Shenma Industrial Park, Hebei Yan-style cluster. China dominates global capacity (~60-70%, ~30-35 Mt/yr). Major Chinese capacity is increasingly producing low-emission formaldehyde-resin grades for EU export ahead of August 2026.

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 for formaldehyde is **Annex XVII Restriction 77 emission-limit compliance** (effective 6 August 2026): downstream EU furniture, wood-panel, mattress, textile manufacturers must verify formaldehyde-emission limits at finished-article level. This puts pressure all the way back through the supply chain to formaldehyde-resin producers and ultimately to Chinese-origin formaldehyde producers. Major Chinese producers (Sinopec, Wansheng Chemical Anhui, Wanhua Chemical, Liuyang Chemical Industrial Park, Henan Shenma Industrial Park) are increasingly producing low-emission formaldehyde-resin grades for EU export. The dominant economic story is **the post-2026 formaldehyde-emission-limit compliance cost** that will reshape EU lane economics from August 2026 onward.

Required documents

  • REACH registration number on the EU side (registrant or OR-appointed)
  • Safety Data Sheet (SDS) compliant with REACH Annex II in destination Member State language(s) reflecting H301 / H311 / H314 / H317 / H318 / H331 / H335 / H341 / H350 classification
  • CLP-compliant labelling with GHS05 + GHS06 + GHS08 pictograms and DANGER signal word
  • Customs entry with HS code 291211 (formaldehyde solution / formalin)
  • ADR consignment note for transport (Class 8, UN 1198 / 2209 / 1199, PG III)
  • **Annex XVII Restriction 77 emission-limit conformity declaration** for downstream-finished-article exporters from August 2026
  • Annex XVII Restriction 72 textile-emission concentration declaration
  • EU Reg 1223/2009 cosmetic-product compliance documentation where applicable

Common compliance traps

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

  • **Annex XVII Restriction 77 effective 6 August 2026** is the most-imminent practitioner watch-item for formaldehyde. EU-wide formaldehyde-emission limits from articles will reshape lane economics for wood-panel, furniture, mattress, textile categories
  • Carc 1B + Muta 2 + Acute Tox. 3 + Skin Corr. 1B + Skin Sens 1 hazard profile drives the heaviest workplace exposure-control overhead in the dataset
  • **IARC Group 1 (carcinogenic to humans)** since 2006 IARC Monograph 88, confirmed 2012 IARC Monograph 100F. Notable: only the second IARC Group 1 substance in the dataset (along with TiO2 batch 7 which is IARC Group 2B and EU-Carc-Cat-2-annulled)
  • NOT on SVHC list despite Carc 1B classification (kept off SVHC because of essential industrial use; phenolic resins ~15% of demand, MDI / TDI ~12%, urea-formaldehyde resins ~50%)
  • NO active EU AD case on Chinese-origin formaldehyde (lighter trade-policy posture than caprolactam batch 14)
  • NOT in CBAM Phase 1 scope but EU revision may extend to organic chemicals; long-term watch-item
  • Major Chinese producers: Sinopec Beijing + Sinopec Yanshan, Wansheng Chemical Anhui, Wanhua Chemical Yantai, Liuyang Chemical Industrial Park (Hunan), Henan Shenma Industrial Park, Hebei Yan-style cluster. China dominates global capacity (~60-70%, ~30-35 Mt/yr formaldehyde 37% solution equivalent)
  • Coal-fed Chinese formaldehyde production carries higher embedded CO2 vs gas-fed alternatives; CBAM Phase 2 candidate
