Sweden presented its proposal to add magnesium nitrate hexahydrate (CAS RN 13446-18-9) to Annex II. The main use of this substance is in the form of
fertilisers, by professionals. Other known uses by the public are for making ceramics and in printing, but the impact on the supply chain and
consumers is expected to be low.
There were no major objections to the proposed amendment, but the ensuing discussion extended to other nitrates, including calcium nitrate
tetrahydrate, and to nitrogenous fertilisers as a whole:
Two alternative measures were also discussed, which would consist in (a) adding 'fertilizers with nitrogen content from nitrate equal or higher
than 8 % by weight' or (b) adding 'nitrogenous (solid and liquid) fertilizers with nitrogen (N) content equal or higher than 3% by weight', both as a
group of substances, to Annex II. These two alternative measures have already been discussed in previous SCP meetings1 without reaching consensus. DG
HOME will check whether groups of substances, as opposed to individual substances, can be the subject of delegated acts.
Participants also noted that the inclusion of calcium nitrate in Annex II, as opposed to including calcium nitrate tetrahydrate, could be regarded
as an error, since the tetrahydrate is the form used for fertilizers. DG HOME will check whether the CAS number could be changed as a correction.
In addition, some participants noted that, ideally, all hydrate forms of all the listed nitrate salts should be covered in the Regulation's scope,
since chemical conversions between them are in principle possible. |
