The Applicant Guide: Product Registration (MAPP) Numbers

What is a MAPP number?

This is a unique product registration number allocated upon issue of the first commercial level of authorisation for a product. (For products authorised before 1 July 1999 this was referred to as the MAFF number). The MAPP number assigned remains with your product, unless there is a major change to its identity or to its formulation.

When are new MAPP numbers issued?

New MAPP numbers will be allocated with revised authorisations for or including the following:

A new commercial product (including change in tradename)

Note that MAPP numbers are not allocated to products that only hold trials permit(s) (for research or development purposes) since these are not marketed.

A change in marketing company

A change in marketing company (either on its own or in conjunction with a change in authorisation holder) generally triggers a change in MAPP number. A change in authorisation holder alone, does not generally require a change in MAPP number.

If the company registration number for the marketing company does not change, it may not be necessary to change the MAPP number.

A change in formulation

A major formulation change (which relies on new or previously evaluated data) triggers a new MAPP number. This is to help distinguish between the two different formulations.

At product renewal

There is no requirement to automatically issue a new MAPP number following product renewal.  Experience and discussions with authorisation holders have shown, however, that a change in MAPP number aids stock management and clarity around extensions of authorisation of minor use (EAMUs). Therefore, a new MAPP number is routinely allocated upon completion of the renewal process for professional products.

Conversely the MAPP number for amateur products, where the labels tend to be simpler and less likely to change, is not routinely changed at renewal.

Authorisation holders may request that the MAPP number is/ is not changed at renewal and this will be considered by the Assessment Manager.

Other reasons

There may occasionally be other reasons why either the authorisation holder or HSE considers that it is appropriate to allocate a new MAPP number. These can be discussed with HSE as appropriate.

If my product gets a new MAPP number, what happens to the old number?

When we issue a new authorisation for a product, incorporating a change in MAPP number, the previous authorisation for the old registration number will be withdrawn. This will usually take the form of a phased withdrawal, to allow the authorisation holder to continue placing stocks with the old MAPP number into the supply chain for a limited time, with an additional use-up period to allow stocks in the supply chain to pass through safely (see the guidance document for product withdrawals).

MAPP numbers and Extension of Authorisation for Minor Use (EAMUs)

Where a product authorisation incorporates a change in MAPP number, growers will not be able to use the new product under the terms of any existing Extensions of Authorisation for Minor Use (EAMUs) where these refer only to the old registration number.

It would therefore be helpful if authorisation holders could inform the grower or grower group organisation responsible for any EAMUs in order that they can submit applications to amend affected EAMUs. Providing there has not been a major change to the product's formulation, such requests can usually be dealt with administratively see the guidance document for Extensions of Use.
