REF-14 inspection readiness: the 2026 mixture enforcement project

Through 2026, inspectors across the EU and EEA are checking hazardous mixtures under REF-14, the ECHA Enforcement Forum’s coordinated enforcement project. If you place mixtures on the market, the practical question is not whether poison centre compliance can be inspected — a completed pilot project already proved it can, at scale — but whether your portfolio would pass the specific checks inspectors have now rehearsed. This article separates the two projects precisely, because they are routinely conflated: the striking numbers you may have seen (19% not notified, 15% without a UFI) come from the pilot, reported in February 2026. REF-14 is the separate, larger project those numbers helped shape.

What REF-14 is

REF projects are the Enforcement Forum’s instrument for coordinated, EU-wide inspection campaigns: member states agree a scope, train inspectors against a common methodology, inspect in parallel, and publish a joint report. REF-14 applies that machinery to mixtures. Preparation and training ran to the end of 2025, the inspection phase runs through 2026, and the consolidated report is expected in 2027. National enforcement authorities do the inspecting — REF-14 gives them a shared checklist and a reason to prioritise mixtures this year.

The scope is broader than poison centre duties alone. Inspectors will check classification, labelling, packaging — including child-resistant fastenings — poison centre notifications, and the safety data sheets of hazardous mixtures in consumer products, alongside compliance with REACH restrictions and the POPs Regulation. For a company whose CLP fundamentals are in order, the PCN and UFI checks are the most likely gap, simply because they are the newest duties; the broader obligations are covered in PCN enforcement.

REF-14 is not the pilot — and the numbers belong to the pilot

In 2025 the Forum ran a pilot project specifically on poison centre notifications: 18 EU/EEA countries, 1,597 mixtures checked between January and June 2025, report published in February 2026 (ECHA news ECHA/NR/26/08). It was deliberately smaller and narrower than REF-14 — a test of whether PCN compliance could be inspected in practice, given that national authorities have no automatic right of access to the PCN database.

Much of the commentary published since blends the two projects into one “ECHA crackdown,” attributing the pilot’s findings to REF-14. Keeping them apart matters for planning: the pilot is finished and its numbers are historical fact; REF-14 is the live project, its scope is wider, and its results do not exist yet. What the pilot supplies is the best available evidence of where inspectors find problems — which is exactly how the Forum uses it.

What the pilot found — and why it predicts inspector focus

All figures below are the pilot’s, from the February 2026 report:

• 19% not notified. Of the 1,432 inspected mixtures that required a PCN, no notification existed for 19%. This was the single most frequent failure.
• 15% without a UFI on the label. Where the UFI was required on the label, it was missing in 15% of checked mixtures. Where a UFI was present, its format was valid in 98% of cases — companies that engage with the duty largely get the code itself right.
• 71% of inspected mixtures came from SMEs, with compliance rates at a similar level for SMEs and large companies. SMEs are not worse at this; they are simply most of the market.
• Consistency failures beyond the headline rates. For 13% of notified mixtures the label and the notification disagreed, and the PCN was inconsistent with the SDS in 17% of cases — trade names, volumes and labelling elements drifting apart across documents maintained in different systems.
• 656 non-compliant cases drew enforcement action: written advice in 68% (447 cases), verbal advice 15%, administrative orders 11% (72 cases), fines 5% (30 cases), criminal complaints 4% (29 cases).

The prediction is straightforward. Inspectors now have a rehearsed method, a known non-compliance rate high enough to justify the effort, and a report telling them the cheapest checks — is there a notification, and is the UFI on the label — catch the most failures. REF-14 inherits all three.

How a typical inspection unfolds

The pilot ran inspections on-site (28%), as desk checks (32%), or both (41%), with mixtures selected off market shelves, through risk-based targeting, or via customs data. The sequence a duty holder experiences looks like this:

1. A product is picked — often literally off the shelf, which means the inspector starts from your consumer-facing label, not from your records.
2. Label check.Classification elements, and the UFI: present, prefixed “UFI:”, correctly structured, correctly placed under Article 25 CLP. The formal rules are in UFI label requirements.
3. Database lookup. The inspector — typically via the national appointed body or poison centre — checks whether a notification exists for that UFI in that market.
4. SDS cross-check. Section 1.1 (does it carry the UFI where required), section 3.2 against the notified composition, section 11 against the notified toxicological information.
5. Follow-up with the duty holder. Questions about anything inconsistent: who notified, when, for which markets, and whether updates kept pace with reformulations.

A readiness checklist you can run this quarter

• Reconcile the portfolio. One list of every mixture you place on the market, one column of PCN submission numbers. Every gap is either an exemption you can name — check whether each product needs a PCN — or a missing notification.
• Check labels against notified UFIs. The code on current artwork must match the code in the notification, character for character. The pilot found label–notification mismatches in 13% of notified mixtures.
• Check SDS section 1.1.For unpackaged and industrial-supply cases where the UFI lives in the SDS, confirm it is actually there — the pilot’s small sample of this case showed 25% non-compliance.
• Document MiM chains. For every mixture-in-mixture component, record the supplier UFI or supplier details you relied on, so an inspector’s question about a component does not become a scramble.
• Clear the update backlog. Reformulations, new markets, changed trade names — every one should be reflected in an updated notification before an inspector finds the drift.
• Make records retrievable in one day.Submission numbers, dossier copies, ECHA acknowledgements, per product, findable by whoever answers the phone. The pilot’s follow-ups went hardest where companies could not show what they had filed.

If an inspector finds a gap

The pilot’s enforcement profile is the most reassuring number in the report for anyone acting in good faith: 68% of actions were written rectification advice — fix it, show you fixed it. Formal measures were reserved for the minority: administrative orders in 72 cases, fines in 30, criminal complaints in 29. Speed and evidence are what keep a finding in the advice category. Submit the missing poison centre notification immediately, correct the label at the next print run with a documented timeline, and reply to the authority with submission numbers in hand.

If the reconciliation exercise surfaces a backlog, closing it is a bounded task: Ufi Number takes a mixture from formulation data to a submitted, acknowledged notification for €20, which is usually cheaper than one hour of the meeting where you explain the gap.
