The regulation

What changed for mixtures in 2026

Two instruments amend CLP EC 1272/2008 on dates that concern mixtures. Commission Delegated Regulation (EU) 2023/707 added four new hazard classes to CLP Annex I. Regulation (EU) 2024/2865 revised the labelling and advertising rules, and its application dates were rescheduled by Regulation (EU) 2025/2439.

New hazard classes for mixtures

Before:CLP Annex I had no hazard class for endocrine disruption, PBT/vPvB or PMT/vPvM
2026-05-01:Mixtures are classified under ED HH, ED ENV, PBT/vPvB and PMT/vPvM per Commission Delegated Regulation (EU) 2023/707

Mixtures already on the market

Before:A mixture placed on the market before 2026-05-01 is exempt from the four new hazard classes
2028-05-01:That exemption ends: those mixtures must be classified and labelled under the four new hazard classes

New hazard classes for substances

Before:Substances were classified without the four new Annex I hazard classes
2025-05-01:Substances apply them from 2025-05-01; substances already on the market before that date are exempt until 2026-11-01

Label format and legibility

Before:Labels followed the CLP formatting rules as they stood before Regulation (EU) 2024/2865
2026-07-01:The revised label formatting and legibility rules apply, as rescheduled by Regulation (EU) 2025/2439

Advertising and distance sales

Before:Adverts and online listings for hazardous mixtures carried no CLP information requirement of this kind
2026-07-01:New information requirements apply to advertisements and to distance and online sales of hazardous mixtures

Later Regulation (EU) 2024/2865 tranches

Before:The 2026-07-01 tranche covers label format, legibility, advertising and distance sales
2027-01-01 and 2028-01-01:Further tranches of the revised CLP rules apply from 2027-01-01 and from 2028-01-01

Scope

Who these dates apply to

Any company placing hazardous mixtures on the EU market is in scope, whether the mixture is made in Europe or imported. New mixtures follow 2026-05-01, and mixtures already on the market follow 2028-05-01.

EU Manufacturers & Formulators

Companies that produce chemical mixtures — cleaning products, coatings, adhesives, lubricants, cosmetic formulas — for EU sale must reclassify and update all SDS documents.

Importers into the EU

Any business importing hazardous mixtures into the EU market bears CLP compliance responsibility. Non-EU manufacturers cannot place products on the EU market without a compliant importer.

Distributors & Resellers

Distributors who repackage or relabel mixtures must ensure CLP labels and SDS are compliant before redistribution. Passing on non-compliant documentation from suppliers creates liability.

Consumer Product Brands

Household cleaners, personal care, DIY, and professional-use products classified as hazardous mixtures under CLP must have updated labels and SDS — including UFI codes.

Industrial Chemical Suppliers

Suppliers of industrial intermediates, process chemicals, and specialty chemicals to EU customers must provide a CLP-compliant SDS per REACH Article 31 with each supply.

Online & Cross-Border Sellers

E-commerce sellers offering hazardous mixtures to EU buyers — regardless of physical location — must comply with CLP labelling and SDS requirements per EU distance-sales rules.

Key compliance requirements

A hazardous mixture placed on the EU market from 2026-05-01 needs these documents correct on the day it is placed:

SDS Section 2 — Classification

Must state the full CLP classification of the mixture: hazard class, category, H-statements, and signal word. Must match the label exactly.

SDS Section 3 — Composition

Hazardous ingredients above concentration limits must be disclosed with CAS/EC numbers, CLP classification, and concentration ranges.

CLP-Compliant Label

Hazard pictograms, signal word, hazard statements, precautionary statements, UFI code, and supplier identification — all per CLP Annex II.

UFI Code (Unique Formula Identifier)

Mandatory for hazardous mixtures placed on the EU market. UFI must appear on label and SDS, linked to the ECHA Poison Centres Notification.

What the dates require: mixtures placed on the EU market from 2026-05-01 are classified under the four new CLP Annex I hazard classes. Labels must meet the revised formatting and legibility rules from 2026-07-01. Mixtures already on the market before 2026-05-01 must be reclassified and relabelled by 2028-05-01.

FAQ

EU CLP 2026 — common questions

Which 2026 CLP dates concern mixtures?
Two. Commission Delegated Regulation (EU) 2023/707 added four new hazard classes to CLP Annex I. They are endocrine disruption for human health, endocrine disruption for the environment, PBT/vPvB and PMT/vPvM. Mixtures apply them from 2026-05-01. Separately, Regulation (EU) 2024/2865 revised the label formatting and legibility rules. Those rules, and new information requirements for advertisements and for distance and online sales of hazardous mixtures, apply from 2026-07-01. That schedule comes from Regulation (EU) 2025/2439. No other CLP date falls in 2026 for mixtures.
What must I do about mixtures already on the market?
A mixture placed on the EU market before 2026-05-01 is exempt from the four new hazard classes until 2028-05-01. By that date it must be classified and labelled under them. This transitional period is the live date a supplier can still plan around. For substances the equivalent dates are 2025-05-01, with substances already on the market before then exempt until 2026-11-01.
What is a CLP mixture SDS and how is it different from a regular SDS?
A CLP mixture SDS must classify the mixture as a whole — not just list ingredient hazards — using the bridging principles and calculation methods defined in CLP Annex I. Section 2 of the SDS must state the full CLP hazard classification (class, category, H-statements, signal word) for the mixture itself, and this must exactly match what appears on the product label. Many older SDS documents were prepared under the Dangerous Preparations Directive (DPD) and no longer meet this requirement.
Do I need a UFI code on my SDS and label?
Yes, for hazardous mixtures placed on the EU market. The Unique Formula Identifier (UFI) is a 16-character alphanumeric code that must appear on the label and SDS. It links your product to a Poison Centres Notification (PCN) submitted to ECHA. Consumer and professional-use hazardous mixtures are both in scope. If you are not yet compliant, you need both a PCN submission and a UFI on your documentation.
Who is responsible for CLP compliance — manufacturer or importer?
In the EU, the person who places a substance or mixture on the EU market is responsible for CLP compliance. For EU manufacturers, that's the company itself. For products from outside the EU, the EU importer (the first legal entity to receive the product in the EU) takes on full CLP compliance responsibility. Non-EU companies cannot place products on the EU market without an EU importer who accepts that liability.
Can ChemEngine generate a CLP-compliant SDS for mixtures?
Yes. ChemEngine Datatools generates a draft EU CLP-format SDS per REACH Annex II, applying CLP Annex I classification criteria, for $5. Input a mixture's components (CAS numbers or chemical names) and ChemEngine calculates the mixture classification, populates all 16 SDS sections, and generates the draft document in under 60 seconds — for professional review before EU market submission. The draft does not automatically determine PBT/vPvB or endocrine-disrupting status, and Section 2.3 states that plainly.
