This section contains answers to the most commonly asked questions on the obligations relating to placing hazardous mixtures on the market. If you cannot find the information you are looking for, you can contact ECHA.

Last updated 21/06/2019.


Duty holders and Annex VIII scope
Who has the duty to submit?

Article 45 places direct submission obligations to importers and downstream users based in the European Economic Area, i.e. Members States of the European Union and Norway, Iceland and Liechtenstein. These operators, when placing hazardous mixtures on the market, have to submit information according to Annex VIII to the CLP to the relevant appointed body. Nevertheless, all operators in the supply chain have the obligation to make sure they place on the market mixtures which are in compliance with CLP as a whole. This means that distributors (in particular rebranders/relabellers or companies distributing a mixture in another Member State) may need to submit themselves if the relevant information is not included in a submission made by the supplier.

Please note that the interpretation of the role of certain operators (namely re-branders) has not been agreed among all Member States Competent Authorities. We recommend you to refer to the Guidance on Annex VIII (v.2.0) where detailed information is available.

If I import a product in one Member State but do not sell it on the market in that Member State, am I obliged to submit information there?

Yes. The imported mixture may be used at the first place of import by the importer themselves, or may be imported in Member State A and subsequently placed on the market also in Member State B. Since import is deemed to be “placing on the market”, a submission is required in both member States A and B.

What mixture are in scope?

You need to submit information on mixtures classified for any health or physical hazard and falling under the scope of the CLP Regulation. Therefore the obligations do not apply to substances. You also do not need to make a submission for mixtures intended only for R&D or PPORD. In addition, you do not need to submit mixtures classified only as gases under pressure or explosives. Certain mixtures which are exempted by CLP as a whole (e.g. waste, certain mixtures in the finished state intended for certain uses for which specific legal provisions exist), do not need to be notified even if hazardous.

Note that mixtures which are subject to supplemental labelling requirements according to Part 1 and 2 of Annex II to CLP (e.g. EUH208) but are not themselves classified for health or physical hazards, are not subject to submission requirements and do not need a UFI.

How long is a company liable for a notification?

The information must always be up to date for mixtures as long as they are placed on the market. If the product is no longer placed on the market, the company is not required to update the information.

Note that is no “expiration date” of a notification and the information is expected to remain in the system even after the product is no longer placed on the market.


Information requirements and confidentiality
Which information do I need to submit?

You need to submit harmonised information according to Annex VIII. The information requirements are the same in all Member States where you intend to place the mixture on the market. Details are available in the ‘Information requirements for poison centre notifications’ in brief document – available from ECHAs Poison Centre website in the Publications page under the Support tab.

How can I obtain information on the composition of mixtures I am importing, if the non-EU supplier does not want to disclose it?

It can be difficult to obtain information on the composition of a mixture from a non-EU supplier. However, under both CLP and REACH, importers need to have information on the composition of the mixtures being imported in order to be able to comply with the CLP Regulation. It is up to companies to improve the communication through their supply chain to ensure their compliance with CLP and REACH. It may be helpful to tell suppliers why the information is needed, which may be unknown, particularly to non-EU suppliers. Ultimately, the non-EU supplier may decide, in agreement with the EU importer, to make a voluntary submission (via an EU-based legal entity) and provide the UFI to the actual EU importer, who will then make their own submission under Annex VIII referring to that UFI in the composition. This would allow the protection of the CBI of the non-EU supplier.

Can a Member State request additional information besides what is contained in the agreed harmonised format?
No, for the purpose of Article 45 the information requirements are harmonised at EU level. There is a possibility for limited submission for industrial use if I provide a 24/7 telephone service. What does 24/7 mean, and what languages need to be covered?

The phone service always needs to be available 24 hours a day 7 days a week. The phone service is expected to be in the languages of the Member State where the mixture is placed on the market and should not generate disproportionate costs to the Member State.

As a supplier, how can I avoid disclosing the composition of my mixture to my customer who uses it as a co-formulant in their product?

You can avoid disclosing the composition of your mixture to your customer by providing the UFI. Your downstream users will include that UFI in the notification of their products.


When do I need to submit information according to the new rules?

Annex VIII established specific dates of application according to the end use of the mixture. Whether you are making a new notification, or if you are updating an existing one, you will have to make a notification in accordance to Annex VIII before placing it on the market after 1 January 2020 (consumer use), 1 January 2021 (professional use) or 1 January 2024 (industrial use only). A notification has to be submitted in each Member State where you intend to place the mixture on the market.

Can industry start using the harmonised information requirements before 2020?

It is at the discretion of a Member State to allow the submission of information in a new format before the first date of applicability. ECHA has compiled a table with Member States’ decisions on when they will start accepting submissions according to the new format – more information is available from ECHAs Poison Centre website in the ECHA Submission portal page under the Tools tab.

Do I need to relabel all my mixtures (for adding the UFI) before 1 January 2020?

You do not need to relabel your mixtures if they were notified under national schemes as the notification remains valid until 1 January 2025, unless you need to make an update. When you are required to submit information according to Annex VIII (i.e. in case of changes to existing mixtures or new mixtures), you are also required to relabel your mixtures with the UFI code.

Do I need to re-submit information on the products I previously notified under the existing system?

The notifications already submitted under national legislation will remain valid until 1 January 2025 unless you make any change which requires an update according to Part B of Annex VIII. In that case, you are required to comply with Annex VIII before placing the mixture as modified on the market. If you intend to place the same mixture on the market after 1 January 2025, a submission according to Annex VIII will be required starting from that date.


Unique Formula Identifier (UFI) and labelling
Can companies generate UFIs and already place them on the label now?

Companies can start generating their UFIs and perform internal preparations such as the mapping with formulation numbers used to generate the UFI. However, placing the UFI on the product label should coincide with the submission of information to the Appointed Body of the relevant MS. It is not recommended to place the UFI on the product if it has not been included in a prior submission.

Can different UFIs be used for a single mixture that is placed on the market with different trade names and possibly by different companies?

Yes, a company can generate multiple UFIs for the same mixture, placed on the market under the same or different trade names. Potentially, the same UFI can be used by different companies along the supply chain, as long as the composition remains the same. The UFI is linked to a mixture composition rather than a product, which means that you can have one or more UFIs for the same mixture, regardless of any trade names associated to it

The management of the UFIs is relatively flexible, and can be adapted to the business needs of the companies. This means that you could decide, for example, to assign different UFIs according to the market area, or according to the language, or according to the trade name.

The UFI is generated based on the VAT number of the company. Does it mean that if a legal entity changes (due to a split or merger) new UFIs will need to be generated?

The VAT number is only a means to generate UFIs. After the UFI is generated, this does not need to be linked to a specific company. The same UFI can be used by different companies as long as the composition of the mixture remains the same.

Is it possible that the exact same UFI could be generated by two unrelated companies? How about related companies, e.g. multi-nationals with several subsidiaries?

Individual companies have distinct VAT numbers, therefore the duplication of UFIs is not possible. However, UFIs for subsidiaries must be carefully managed by the parent company to avoid the generation of duplicates. For example the parent company can generate and distribute UFIs for the subsidiaries using one central VAT number.

Is a company obliged to use their VAT number to generate the UFI?

Given that the VAT number is generally not confidential, companies are to use their own VAT number to generate their UFIs. However, a ‘company key’ code can be generated and used by companies who 1. do not have an EU VAT number and 2. have implemented the UFI algorithm into their own systems.

For companies without an EU VAT number using the online UFI generator tool, a specific function allows the generation of an ‘invisible’ company key code each time a new UFI is generated.

I’m a private label formulator of a mixture and I have several customers for this mixture. How should the UFI codes for the different customers be managed?

The use of the UFIs is flexible. In principle, you can use one single UFI for all your customers along the supply chain, as long as the composition remains the same. Note that if the mixture is placed on the market under different trade names, all these have to be included in a submission made by you or your customers.

Please consult the Guidance on Annex VIII (section 4.2 in particular) available from ECHAs Poison Centre website under the Support tab for more details.

Am I obliged to put the UFI on the label of my product? What about on the packaging?

The UFI must always be on the label (or in some cases, in close proximity to the other labelling elements on the packaging) of all hazardous mixtures in accordance with Annex VIII and included in the submission of information. Note that there are derogations for the UFI labelling e.g. in the case of industrial mixtures or mixtures not packaged, where it is sufficient to include the UFI only in the SDS (Section 1.1).

For the submission of mixtures outside of scope, including the UFI on the label of non-hazardous mixtures will remain voluntary.

Are there any guidelines for the UFI on the label?

There are no specific rules on how to display the UFI. Nevertheless, the UFI has to be clearly visible, legible, and indelibly marked i.e. it can't wash off. Printing techniques need to meet these requirements. Please consult the Guidance on Annex VIII (section 4.2.8 in particular) available from ECHAs Poison Centre website under the Support tab for more details.

How is the UFI placed on the label of a multi-component product?

All hazardous mixtures within a multi-component product require their own notification and UFI. As a general rule, the UFIs of all the mixtures which are part of the final product should appear on the label.

Does the UFI need to be on both the intermediate packaging and outer label?

CLP labelling is normally required on every layer of a packaging intended for supply and use. Further details on the considerations and exemptions from the labelling and packaging requirements are covered in the Guidance on labelling and packaging.


Mixture in mixture (MiM) components
How do I declare the components of the MiM in my final mixture?

You have three possibilities. If you know all the components of the MiM, you need to list them like you would do with the other substance components of your mixture. If you do not know all the components of the MiM, and the MiM has been notified by the supplier in the same Member State, you can use the UFI of the MiM together with its identifier. As a last resort, you can identify the MiM by providing its SDS and the details of the supplier, in addition to the MiM’s name.

If a supplier informs me that their UFI has changed do I need to update my submission?

Yes, when the UFI of the MiM has changed it may imply that the composition of the MiM has changed and therefore it may require an update also on your final mixture.

I am formulating a mixture using a non-hazardous mixture from another supplier. How do I get the compositional information on this mixture (my MiM) for my submission?

Establishing good communication in the supply chain is a key factor. You can either request the compositional information from your supplier, or if they have made a voluntary submission, they can also provide you with a UFI instead. In any case, you should have some information on the composition, e.g. the name of the main component and its CAS number.

In any case, putting the UFI on the label of non-hazardous mixtures voluntarily notified will also remain voluntary.

The mixture I formulate is meant for industrial use, therefore I can opt for a limited submission. What if the mixture ends up as a MiM in a consumer product?

When submitting information on a mixture, the duty holder must comply with the date of applicability according to the end use type of their ‘original’ mixture. That is, if a mixture originally formulated for industrial use ends up in a ‘final mixture’ intended for consumer or professional use, the duty holder should make their submission according to the requirements (and relevant date of applicability) set for consumer or professional use.

I have two suppliers for the same MiM, which I alternatively use for the formulation of my final mixture (according to the availability). Can I include the information for these two MiMs (SDS for example and UFI code) in the same submission?

In the situation where the component purchased from different suppliers is identical (i.e. same composition and hazard profile), you do not need to provide all the UFIs (the one that has been notified in the relevant country would be enough). If you cannot be sure that the two MiMs are the same, it cannot be assumed the composition of your final mixture remains the same. Therefore two different notifications would be needed.


Tools for preparing and submitting notifications
What are the differences between online and offline preparation of PCN dossiers?

Online preparation of notifications in IUCLID Cloud offers a user friendly interface with a specific guided dossier preparation functionality for PCN notifications. In addition to this, preparing in the Cloud means you can safely store all you data online without having to concern yourself with any maintenance or updates of the tool, nor with backing up your data. Online preparation also simplifies the submission process in the Submission portal with the click of a button.

Offline preparation using IUCLID 6 offers the same guided dosser preparation interface allows you to maintain all your information locally. Users will however, need to download the latest version from the IUCLID website and install and maintain it themselves. A server version is available for multi-user companies.

When can we use the ECHA Submission portal to start submitting?

ECHA released the first operational version of the ECHA Submission Portal in April 2019 allowing companies to submit notifications and appointed bodies to receive them. Please refer to the table ‘Overview of Member States’ decisions on implementing Annex VIII of the CLP’ to see when each Member State will accept notifications via the ECHA Submission portal.  

Please consult the table ‘Overview of Member states decisions on implementing Annex VIII of the CLP’, in ECHA Submission portal page.

Will Member States keep their own national submission systems?

Some Member States have expressed that they will adapt their national submission systems to receive poison centre notifications, and will operate in parallel to the ECHA Submission portal. Since the format and requirements for the submissions have been harmonised across the EU, any submission system (centralised or national) must ensure that it complies with these legal requirements.

Is it possible to make one submission which is then valid for all Member States?

In principle, you need to make a submission to the appointed body in every Member State where you place on the market in the language of that Member State. The ECHA Submission Portal support the multi-country submission by dispatching the notification to the relevant appointed bodies.

As a duty holder, can another company, for example a consultant, submit information on my behalf?

Yes, by making use on the foreign user functionality in the ECHA Account management, it is possible that a consultant can submit on behalf of yourself as the duty holder. However, be aware that you remain liable for the information submitted. Please see the ECHA Accounts Manual on how to work on somebody's behalf available from ECHAs Poison Centre website in the ECHA Submission portal page under the Tools tab.

Who will see the information submitted?

As the notification contains highly sensitive and confidential information, access to this information will be granted exclusively to the persons authorised by the appointed body. This information will be used solely for emergency health response purposes. Upon further agreement, the statistical information gathered on incidents could be shared to identify potential needs for preventative measures.

Who performs validation checks on the information contained in my dossier?

ECHA does not perform any checks on the dossiers submitted to the portal. However, ECHA’s IT tools allow you to validate your own information before you submit in a validation report. Regardless of the support offered by ECHA’s automated validation tool, it will not replace any manual verification performed by Member States, therefore validating the quality or adequacy of the information submitted will remain at national level.

Before submitting, can I see the same validation report that the Appointed Body will receive from the portal when downloading notifications?

During the dossier preparation phase, the ‘validate’ functionality can check the dossier information prior to submitting using a set type of rules, e.g. if a valid UFI has been provided. A validation report will be available to assess the rules that were triggered (if any) and edit any information as a result.

A second validation will also occur in the portal after you submit your dossier. These include additional checks that can only be checked by the portal itself, e.g. if the UFI has already been submitted. After the dossier has been submitted, a validation report containing the results from the full set of checks will be visible to both you and the appointed body at the same time.

Will the online tools be translated to assist SMEs?

The guided dossier preparation functionality for poison centre notifications in IUCLID Cloud is currently only available in English. A future version aims to support all EU languages by translating the user interface, structured information fields (i.e. picklists) and online help. Any free text fields such as the toxicological information will still need to be provided by the submitter in all relevant languages.

What will happen to the information previously submitted under the national systems? Will it be migrated to the new database?

Two databases (one with the existing notifications and one with the new notifications) can co-exist at national level. The decision to migrate (incorporate existing data to the new database) is at the discretion of Member States.

Currently there is no plan to facilitate the transfer of information already submitted via the current national systems into the ECHA Submission Portal. Each Member State will decide how to manage the information already submitted nationally. Please, note that if you have notified a mixture to the national system, you may benefit from the transitional period until 2025 (unless a change to the mixture occurs).


Fees and language requirements
Will Member States charge fees for Annex VIII submissions?

Although ECHA itself will not charge any fees, it will remain at the discretion of the Member States whether to charge fees for the submission of information. The financial transactions are expected to continue being settled between submitters and the relevant national appointed body. Please consult the table ‘Member States’ decisions on implementing Annex VIII of the CLP’, available from ECHAs Poison Centre website in the ECHA Submission portal page under the Tools tab for more details.

Does the ECHA Submission portal support invoicing from the appointed body?

No, this functionality does not exist in the ECHA Submission portal and such communications will be required to take place through a different channel. You are encouraged to consult with the relevant appointed body before you submit to understand your obligations.

Can I prepare the notification in my preferred language, which upon submission through the portal, would then be converted into the language of the receiving Member State?

Currently the online preparation and submission tools are only available in English, i.e. the user interface and the selectable criteria in the form of picklists. Nevertheless, there are several free text fields e.g. toxicological information, that requires you to manually enter the information in the language accepted by the Member State. A future version of the tool aims to support multilingualism through the use of translated picklist fields.
