EU Deadlines Cluster in 2026: Check Ingredients, Labels, and Packaging Now

What changed, and when?

2026 packs an unusually dense set of EU cosmetic deadlines. On 1 May the compliance and withdrawal deadline passed for newly classified CMR (carcinogenic, mutagenic, reprotoxic) substances, and products containing 4-MBC fell due for withdrawal on the same date. On 31 July the expanded fragrance allergen declaration began applying to newly placed products, and 10 October brings the PFHxA ban. Ingredient Regulation 2026/909 entered into force on 18 May, with many of its main compliance deadlines falling in 2027.

This calendar summarizes published regulatory guidance; actual applicability depends on product type, ingredient concentration, and when the product is placed on the market. Treat these dates as a way to sequence preparation, and confirm final requirements against the official texts and with your EU Responsible Person.

• 1 May 2026 — compliance and withdrawal deadline for newly classified CMR substances; 4-MBC withdrawal
• 18 May 2026 — Regulation 2026/909 enters into force (main deadlines in 2027)
• 31 July 2026 — expanded fragrance allergen labeling applies to newly placed products
• 10 October 2026 — PFHxA ban
• 31 July 2028 — end of the sell-through period for existing stock

1. Eighty-two allergens is not only a labeling problem

The amendment (Regulation 2023/1545) expanded the fragrance allergens requiring declaration from 26 to 82—56 newly added. The thresholds for declaration are above 0.01% in rinse-off products and above 0.001% in leave-on products.

The practical burden sits in obtaining information, not in printing labels. Finished-product manufacturers often cannot see the fragrance composition directly, so the items to be declared are only confirmed once the fragrance house supplies presence and concentration data. If that data is late, the entire ingredient declaration stalls.

2. New launches and existing stock run on different clocks

Products newly placed on the EU market after 31 July 2026 must meet the expanded requirement, while products placed before that date may continue to be made available until 31 July 2028—a further two years.

Reading that grace period as 'nothing to do until 2028' complicates inventory management. When old and new labels circulate under one brand at the same time, communication costs with distribution partners rise. It is better to work backward from the expected sell-through date and set a label changeover point in advance.

3. The CMR deadline meant withdrawal, not relabeling

Where the allergen item is a change in how information is displayed, the CMR item is the kind of deadline that requires taking products off the market. Certain newly classified solvents, silver nanomaterials, and hair dye intermediates fell within scope as of 1 May 2026, and the UV filter 4-MBC became subject to withdrawal on the same date.

That is why the two differ in difficulty. A display change ends with reprinting; an ingredient change leads into reformulation, renewed stability assessment, and re-confirmation of sensory performance. Plan it as different work, on a different schedule and budget.

4. The nearest deadline is 10 October

As transitional arrangements for PFAS in cosmetics end, PFHxA is prohibited from being placed on the market from 10 October 2026—the closest deadline as of today.

Fluorinated raw materials are sometimes used in color cosmetics, sun care, and certain hair products for water repellency and wear. Rather than relying on a scan of the ingredient list, confirm use directly with raw material suppliers. Documenting that a material is not used is also worth keeping, so the same question does not have to be answered repeatedly.

5. Packaging is now on the checklist too

The scope does not stop at what is inside the bottle. With the EU Packaging and Packaging Waste Regulation (PPWR) applying from 12 August 2026, limits on PFAS and heavy metal concentrations and traceability requirements extend to packaging.

A brand cannot verify this alone; the answers come from container and component suppliers. Keeping formula records and packaging records inside one documentation system reduces the need to gather everything from scratch each time another market adds a requirement.

The first question for the brief

Write down when this product will be placed on the EU market, then work backward from that date to the requirements that will apply. Settling just three things—who obtains the fragrance allergen data and by when, whether any ingredient needs replacing, and which supplier provides the packaging records—usually exposes the bottlenecks. Regulatory deadlines are not negotiable, but the order of preparation is yours to choose.
