IFRA-IOFI Labelling Manual

The Labelling Manual provides guidance for fragrance and flavor companies based on United Nations rules on classification and labelling of chemicals.


The IFRA-IOFI Labelling Manual assigns hazard classifications and labelling guidance for fragrance and flavor materials following the rules of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and the UN Recommendations on the Transport of Dangerous Goods (TDG).

Prepared by the IFRA-IOFI GHS Task Force, the Labelling Manual classifies fragrance and flavour materials following the criteria laid out in the United Nations GHS guidance document, known as the 'Purple Book'.

The Labelling Manual contains all classifications that have been ratified by the GHS Task Force since its creation in autumn 2008. 

A new edition of the Labelling Manual is produced in January each year. The latest edition, published in January 2021, is the 2020 Labelling Manual. All previous editions should be considered obsolete.

The IFRA-IOFI Labelling Manual is a single document consisting of an Introduction, the Labelling Manual 2020, and an Annex I with Terms and Conditions of Use.

The Introduction contains a disclaimer and some general considerations and specific details on how the 2020 Labelling Manual has been created.

The Terms and Conditions outline rules for using the Labelling Manual and for sharing it outside your company or organization (such as with service providers for the implementation of the data in software applications).


In line with established practice, after the publication of the Labelling Manual (on 11 January 2021) IFRA and IOFI members are encouraged to implement the new or modified classifications within six months.

However, it is important to note that the information in the Labelling Manual represents the views of the IFRA-IOFI GHS Task Force. It does not create an industry standard, and is provided as only one source of information to be considered in developing warnings or labelling.

In addition, it does not constitute the findings of safety or a judgment as to whether any product requires special handling.

Terms and Conditions of Use

The Labelling Manual includes a series of Terms and Conditions of Use that must be accepted by users. Your attention is drawn in particular to Section 6 – Disclaimer.

The guidance provided by IFRA and IOFI does not relieve users of the Labelling Manual of their obligations to comply with applicable laws and regulations.

The information provided is not legal advice regarding compliance in any jurisdiction and should not be considered or used as a substitute for legal advice. Users of the Labelling Manual should seek legal counsel on questions of compliance.



Classifications in the Labelling Manual do not reflect deviations resulting from local implementation. Nevertheless, the IFRA-IOFI GHS Task Force may provide help, upon request and if found appropriate, should local GHS implementation deviate from the Labelling Manual.
