Explanatory Notes

Notice Types

Authorisations: An Authorisation notice gives the conditions of the Authorisation for a product. Prior to the legislation change on 14 June 2011, these were known as Approval notices

Withdrawal notices: Authorisations are withdrawn via the issue of a "withdrawal" notice which sets an expiry date for the authorisation. In most cases, the withdrawal notice allows for a grace period to allow use of stocks already in the supply chain. However, where there are safety concerns, the withdrawal may be immediate. The withdrawal notice refers back to the original authorisation, and the conditions of that authorisation. Prior to the legislation change on 14 June 2011, these were known as Revocation notices.

Authorisations may be withdrawn at any time for various regulatory or commercial reasons. For example, a withdrawal notice would be issued if authorisation conditions change; if the authorisation holder fails to meet a data submission deadline; following a review; or at the request of the authorisation holder. Each withdrawal has an explanation of the reason for the withdrawal (types of withdrawal are summarised at

Amendments: We sometimes need to reflect the same change to a number of different authorisations (for example when the authorisation holder changes for a group of products). Rather than amend each individual authorisation, we can make changes to the conditions of authorisation via an amendment notice. This describes the nature of the change and lists all the products affected. You will note that the amendment notice refers back to the original authorisations, and all other conditions of those authorisations.

Expiry Dates

The expiry date shown is the final expiry date of the product.

However, we actually specify two expiry dates on our authorisations, reflecting the expiry dates that apply to:

  • sale and distribution by any persons
  • disposal, storage and use by any persons.

Please check individual authorisations for details of expiry.

Where the expiry date shown is 09/09/2099, an extension of authorisation under Article 43 of Regulation (EC) No 1107/2009 has been applied. The authorisation will be withdrawn once a regulatory decision has been taken as explained under "Extensions to Existing Authorisations During Renewal process" in Guidance on UK Procedures for product renewal applications (Article 43 of Regulation 1107/2009 (GB/NI)).

Crop or use expiry dates may differ from the product expiry dates. Please refer to the most recently issued withdrawal notices for details of the expiry dates of individual uses.

'Extent of Authorisation' and expiry dates

Since 1 January 2021 decisions in the EU and UK may mean the final expiry dates for a single MAPP number are different in Northern Ireland (NI) which follows EU rules, and Great Britain (GB) which is operating an independent PPP regime. When the only difference is the expiry date, the same MAPP number is retained in both regimes. This will result in more than one retrieved row for the same MAPP number; each with different expiry dates and 'extent of authorisation'. The latter entry will show whether the specific expiry date applies to GB or NI.

However, for current technical reasons, one authorisation may be listed in 'extent of authorisation' as 'GB only' or 'NI only' but the other may be 'GB and NI'. In such cases, the ('GB and NI') expiry date should be read as excluding the territory ('GB' or 'NI') given in the other single territory authorisation
