This substance has a registration classification as "corrosive Cat. 1B" according to the ECHA. According to the BfR guideline on the classification of dangerous goods under the aspect of "corrosive effect on living tissue", this corresponds to packing group II or III. Because BAM does not have any data for a more precise assessment, the less favourable case (worst case) was assumed here, and packing group II was recommended. If appropriate classification data are available to the user, classification in packing group III may also be possible.
