The quantity is rather curious.

5.5 kg of the stuff would be on the same order of magnitude as the other items on the list. On the other hand (as someone who used to order chemicals frequently), no one would order a quantity with such precision. The precision is out-of-line with the other items on the list.

Could this be an attempt to "sneak one by"?

That is a great comment. In fact in the same list you notice that they have used some values with comma but not with that precision. For example for the Phosphorus Oxycholride they showed a quantity of 3,5 Liter (3.5 liter) and not 3,500 liters which lead me to believe that 5,500 Kg (as written in Arabic) of Phosphorus Pentasulfide is not 5.5 Kg but rather five thousands and five hundred Kg.
