This applies to ammonium nitrate and ammonium nitrate compounds in which the nitrogen content as a result of the ammonium nitrate is more than 28 % by weight (compounds other than those referred to in Note 2) and to aqueous ammonium nitrate solutions in which the concentration of ammonium nitrate is more than 90 % by weight.
Cela s'applique au nitrate d'ammonium et aux mélanges de nitrate d'ammonium dans lesquels la teneur en azote due au nitrate d'ammonium est supérieure à 28 % en poids (autres que ceux visés à la note 2) et aux solutions aqueuses de nitrate d'ammonium dans lesquelles la concentration de nitrate d'ammonium est supérieure à 90 % en poids.
