UFI Update

UFI Update

3 mins read

The unique formula identifier, known by its acronym UFI, is a 16-character alphanumeric code that needs to be included on the Product CLP label.

An earlier blog of ours covers UFI’s in more detail, we recommended reading that first if you’d like more information around UFI regulations. 

New UFI Regulations - What You Need To Know

UFI not required at 10%

As some of you may be aware already, when used at 10% in a non-hazardous base, some fragrances do not require a UFI number as they do not trigger any health or physical hazards. (Although you can, if you wish, still include a UFI number on your CLP label and voluntarily submit the UFI dossier to the PCN/NPIS).

Our fragrance oils that do not require UFI’s at 10% or below when used in a non-hazardous base are listed below:


55 Shades Almond Milk - Reformulated
Amber & Citrus Ancient Woodlands
Apple & Ginger Cake  Australian Bush - Reformulated
Australian Sandalwood - Reformulated Beyond Fabulous

As new oils that don't require a UFI at 10% are being added regularly, we’ve also added a section to our website grouping these oils to make it easier to shop; this can be found here.

Please note that if these oils are used in a hazardous base (such as Augeo or perfumer’s alcohol) then a UFI number will be required.  If you are using these fragrances at a concentration of more than 10% then a UFI number may be required.

Why do these oils not need a UFI?

Among the mixtures which fall under the scope of the CLP Regulation, those classified for environmental hazards only are outside the scope of Article 45 and information according to Annex VIII does not need to be submitted. Also, mixtures which are subject to supplemental labelling requirements according to Part 1 and 2 of Annex II to CLP but are not themselves classified for health or physical hazards are not subject to submission requirements.

In other words, if the product only triggers environmental hazards (H400, H410, H411, H412) and /or only has supplemental information on the CLP label (e.g. Contains: XXX, YYY, ZZZ. May cause an allergic reaction.) it will not require a UFI number.

Does the Windsor Agreement change the need to have UFIs in Northern Ireland? 

Unfortunately, not. Under the NI Protocol, EU CLP regulations were adopted in order to maintain the free movement of goods on the island of Ireland and in turn to the EU. The Windsor Agreement does not include changes to the movement of chemicals (hazardous substances) and therefore the requirement to comply with the EU CLP regulations including the UFI requirements still stands.

This has really been so helpful and made me feel more at ease. I felt like I was going backwards and being told different things regarding UFI numbers.

Such a useful addition to the site – as someone who has been slowly working through getting UFI dossiers submitted for all my products that need it, I’ll certainly be looking towards these fragrances where they fit!
