The rumour that phenol is on the SVHC Candidate List has circulated in resin supply-chain forums for months. It is not. Phenol (CAS 108-95-2) is not on the REACH Candidate List of substances of very high concern; the only 2026 additions so far are n-hexane and Bisphenol AF, entered on 4 February 2026 and covered in our ECHA spring roundup. No phenol identification proposal is active in ECHA’s registry of SVHC intentions, though a phenol-derived substance (oligomerisation and alkylation reaction products of 2-phenylpropene and phenol) has a live intention.

What is real, and much closer, is the formaldehyde restriction under Annex XVII Entry 77 of REACH. Commission Regulation (EU) 2023/1464 amended Annex XVII on 17 July 2023 and set a 36-month transition. The restriction applies from 6 August 2026 for articles other than road vehicles, and from 6 August 2027 for road-vehicle interiors. That is four weeks away for phenol-formaldehyde resin producers whose resin ends up in wood-based panels, laminates, or fibre composites destined for consumer use.

The confusion is understandable. Phenol-formaldehyde resins are named after both monomers, and the SVHC and Annex XVII tracks both live in ECHA’s public registers. But they are legally distinct instruments with distinct triggers, and the documentation obligations differ.

What Entry 77 actually restricts

Entry 77 does not restrict formaldehyde as a substance or phenol-formaldehyde resins as a class. It restricts formaldehyde emission from finished articles measured under a defined chamber method. The two limits are 0.062 mg/m3 for furniture and wood-based articles, and 0.080 mg/m3 for other articles inside the scope. Road-vehicle interior air is capped at 0.062 mg/m3 measured under ISO 12219-1 or ISO 12219-10 in ambient mode.

Scope covers wood-based panels and finished furniture, paper decors, resin-based fibre composites including GRP laminates and gelcoats, adhesives, sealants, sealing tapes, release agents, paints, carpets, and PVC flooring. Toys are inside the scope even though they already carry a formaldehyde restriction from a separate track.

Exemptions are narrower than the resin trade sometimes hopes. Articles from naturally formaldehyde-containing materials are out. Articles for exclusive outdoor use are out. Industrial and professional-use articles are out unless the general public is exposed. Medical devices, personal protective equipment, food-contact materials, biocidal products, secondhand articles, and construction articles used outside the building shell are out. Business-to-business chemical intermediates are not the target: an article is what falls under Entry 77.

Where phenol-formaldehyde resins sit

Phenol-formaldehyde (PF) resins, together with urea-formaldehyde (UF) and melamine-urea-formaldehyde (MUF), are the main binder chemistries in medium-density fibreboard, particleboard, plywood, and oriented strand board. They are also present in GRP composites, phenolic laminates, and a range of moulded parts. Under normal cure conditions, PF resins release less residual formaldehyde than UF, which is why they dominate exterior-grade and structural panels; but the Entry 77 limit is an emission limit on the finished article, and even low emitters have to demonstrate it. There is no PF exemption written into the entry.

The formaldehyde substance itself carries a harmonised classification as Carcinogen 1B and Mutagen 2 under CLP, and inhalation exposure limits under OELs are separately tracked. Entry 77 does not add a new hazard classification; it forces measured emission data at the article level to become the burden of proof.

Documentation that should already exist

For an article manufacturer or importer inside the scope, the file that Entry 77 assumes exists on 6 August contains, at minimum, the following.

A test report from an accredited laboratory using the chamber method specified in Appendix 14 (for wood-based and general articles) or ISO 12219-1/10 for road-vehicle interiors, dated within the material-composition envelope currently in production. Repeat testing frequency has to be defensible on batch-representativeness grounds, not on cost grounds.

A batch-traceability file that ties each production lot of resin to the panel or article lots it feeds, with the resin cure conditions logged (press temperature, cycle time, catalyst loading). Cure conditions are what determine residual free formaldehyde and its later emission. This is where PF resin producers who sell to panel converters need to have supplied their customers with cure guidance and the emission test data behind it.

A resin-side quality file with free-formaldehyde content per lot (typically by hydroxylamine hydrochloride titration or comparable), the formaldehyde-to-phenol molar ratio at synthesis, and residual monomer data. This is not a new requirement under Entry 77; it is the existing safety-data-sheet and downstream-communication chain that Entry 77 assumes is functional.

A supplier declaration confirming that the resin, as supplied under the stated cure protocol, produces finished articles that meet 0.062 mg/m3 (or 0.080 mg/m3 for non-wood articles). Where a resin producer supplies for use in road-vehicle interiors, a separate declaration covers the 6 August 2027 date and the ISO 12219 test regime.

Ongoing PAT records for cure-endpoint monitoring, where inline analytics are deployed. Inline mid-infrared and process Raman on resin lines are the routine methods for cure-endpoint control in EU MUF and PF converters; the inline-Raman comparison covers the peer set. Under Entry 77, cure-endpoint records become part of the traceability evidence that a specific lot met the tested cure conditions.

What the myth gets wrong, and why it matters

The confusion between “phenol is going SVHC” and “formaldehyde restriction takes effect” has a real cost. Producers reading only the SVHC track have prepared Article 33 notifications and SCIP dossiers that Entry 77 does not require. Meanwhile the same producers may not have booked a chamber test slot at an accredited laboratory before the August wave, and testing capacity across notified bodies is under pressure. The PAT inspector expectations we covered in field notes apply here too: the file has to exist before it is asked for.

There is also a separate, quieter track worth watching. Phenol is on the CoRAP evaluation list under substance-evaluation procedures, most recently reviewed for reproductive toxicity endpoints. Substance evaluation does not equal SVHC identification, and no ECHA decision has moved phenol toward the Candidate List. But if that changes over the next two years, the SVHC obligations will come in on top of Entry 77, not instead of it.

What to have ready by 6 August

Producers who have not yet completed chamber-method testing on their finished-article portfolio should treat the next four weeks as a compliance sprint, not a comfortable margin. Where testing is done, the file should sit alongside batch records, cure logs, and supplier declarations in a form an auditor or downstream customer can read without further explanation. Where testing is outstanding, communicate to downstream customers now.

Entry 77 is a measured-emission regime, not a classification regime. The evidence is the number that comes out of the chamber, referenced to a specific article on a specific date, tied back to a specific resin batch and cure protocol. Everything else - SVHC status, CoRAP, harmonised classification - lives in adjacent regulatory tracks that this restriction does not depend on.
