Is it mandatory to include the UFI code on the label?

If you’re a manufacturer or distributor of chemical products, you might be wondering about the obligations surrounding the Unique Formula Identifier (UFI code) on your product labels and packaging. Here's a short guide to help you navigate these requirements.

What is the UFI code?

The UFI code (Unique Formula Identifier) is a 16-character alphanumeric code required for hazardous mixtures. It serves as a unique identifier that links a mixture to specific information about its composition, helping poison centres and emergency responders in case of incidents.

Is it mandatory to put the UFI code on the label of my product?

Yes, for hazardous mixtures, the UFI code must be on the label or in close proximity to other labelling elements on the packaging. This requirement is in accordance with Annex VIII of the CLP (Classification, Labelling, and Packaging) Regulation. The UFI code must also be included in the submission of information to poison centres.

However, there are some derogations:

  • Industrial use only mixtures: If the mixture is intended for use exclusively at industrial sites, the UFI code can be indicated in the Safety Data Sheet (SDS) under section 1.1, instead of on the label or packaging.

  • Non-packaged mixtures: For mixtures that are not packaged, the UFI code must be included in the SDS (Section 1.1).

For non-hazardous mixtures, including the UFI on the label is voluntary and not mandated by the regulation.

UFI code and CLP labelling requirements

UFI code on packaging layers

The UFI code does not need to be on every layer of packaging. It is sufficient to include it on the inner packaging. If it’s not feasible to place the UFI on the inner packaging, it can be placed on a fold-out label or on the outer packaging, provided it is close to other required labelling elements.

Detailed Guidance and Exemptions

For comprehensive details on labelling and packaging requirements, including specific considerations and exemptions, refer to the Guidance on Labelling and Packaging provided by ECHA.

We have already written about the topic of placing the UFI code on labels in the blog post "Requirements of labeling in accordance with the CLP Regulation", where more useful information is available.
