4. Date Marking: PAO vs Best-Before
According to Russell Regulatory Consultants, the 30-month rule determines which marking to use:
| Shelf Life | Marking Required | Symbol/Format |
|---|---|---|
| 30 months or less | Best Before End (BBE) date | Hourglass symbol + MM/YYYY |
| More than 30 months | Period After Opening (PAO) | Open jar symbol + months (e.g., 12M) |
| Single-use products | Neither required | Products used once and discarded |
| Products in sealed packaging | PAO not required | If opening cannot cause deterioration |
Source: UK Retained Regulation 1223/2009 Article 19
The PAO (Period After Opening) symbol is an open jar icon with the number of months the product remains safe after first opening:
PAO Symbol Requirements

UK-Specific Restrictions
Common Labeling Errors
According to CTPA, common labeling mistakes include:
Common UK Labeling Errors to Avoid
- Missing or incorrect UK RP address (still showing only EU RP after 2027)
- Ingredients not in descending order by weight
- Missing allergen declarations above threshold
- Using common names instead of INCI nomenclature
- Missing mandatory warnings for restricted ingredients
- PAO symbol without time period (e.g., open jar with no '12M')
- Batch code missing or illegible
- Information not in English (mandatory language)
- Claims that contradict product category (e.g., 'cures acne' for cosmetic)
- Nominal content in imperial only (metric required)
Online Sales Labeling
According to CMS legal guidance:
For online/distance sales, certain information must be available before purchase:
| Information | Required Pre-Purchase? | How to Display |
|---|---|---|
| Ingredient list | Yes | Product page or linked document |
| Function of product | Yes | Product description |
| Nominal content | Yes | Product specifications |
| Precautions and warnings | Yes | Product page |
| PAO/BBE | Not required | On physical product only |
| Batch number | Not required | On physical product only |
Source: UK Distance Selling Regulations
UK cosmetic labels must include: (1) UK Responsible Person name and address, (2) country of origin (if manufactured outside UK), (3) nominal content (weight/volume), (4) best-before date or PAO symbol, (5) batch/lot number, (6) function of product if not obvious, (7) ingredients list in INCI format in descending order, and (8) any required precautions or warnings for specific ingredients.
Yes, until December 31, 2027 under the transitional provision. After this date, products sold in Great Britain must display a UK-based Responsible Person address. Products placed on market before the deadline can continue being sold until stock is exhausted. Best practice is to add UK RP details now to avoid future relabeling.
English is mandatory for all consumer-facing information on cosmetics sold in Great Britain. This includes the ingredient list header ('Ingredients'), precautions, warnings, directions for use, and function description. INCI names (standardized across languages) do not require translation. Additional languages are permitted alongside English.
No, you need one or the other based on shelf life. If the product has a shelf life of 30 months or less, use a best-before date (BBE with hourglass symbol). If shelf life exceeds 30 months, use the PAO (Period After Opening) symbol showing months of safe use after first opening (e.g., 12M). Single-use products exempt from both.
The 26 designated fragrance allergens must be individually declared by their INCI names if present above 0.001% (10 ppm) in leave-on products or 0.01% (100 ppm) in rinse-off products. They appear in the ingredient list (usually near the end after other ingredients). You must also list 'Parfum' or 'Aroma' for the fragrance itself.
If the container is too small for the full ingredient list, it can appear on the outer packaging only. A hand-pointing symbol must be printed on the container directing consumers to the packaging. If even packaging space is limited, an enclosed leaflet or attached tag is permitted. The hand symbol must be present on both container and packaging pointing to the leaflet.
UK regulations do not specify a batch number format—it's determined by the manufacturer. Common formats include alphanumeric codes (e.g., 'B2024-001'), date-based codes, or sequential numbers. The key requirement is that it enables traceability to manufacturing records, batch documentation, and facilitates recalls if needed.
Yes, for online/distance sales, certain information must be available before purchase on the website: ingredient list, function of product, nominal content, and any precautions or warnings. Batch number and PAO/BBE do not need to be displayed online but must appear on the physical product when delivered. All other labeling rules apply to the product itself.
