Why does my SN have a "5.1 oxidiser" sticker?

[Slate128]

I may be stupid, and there might be something in the megathread I missed, but can anyone help me with this?

Bought 1kg of SN from a chemical distribution firm in my country (NZ) and it arrived today. It has a yellow Oxidiser 5.1 sticker on it, as well a tricoloured black-white-black sticker. I didn't do well in chemistry at high school, so naturally I don't know what any of it means, even after googling, but I know 'combustion' is bad and I don't want that. Can anyone enlighten me as to what that all means?

I just want to ctb peacefully, not blow up my neighbourhood lol

SN is basically stable. It will not spontaneously combust.

A 5.1 Oxidizer is a substance that may enhance the combustion of other substances. So don't combine it with gasoline

Without seeing it, the black/white/black label likely signals a Class 9 Hazmat, which is for miscellaneous materials. This category includes dry ice and asbestos, among other things. SN is not important enough, as a quantity of goods sold or in terms of danger, to be classified higher.

Can you take a pic of the black and white sticker? I did fairly well in Honors Chem.

As far as the B&W one goes, I'm not entirely sure. It's a UK label and I think it just signifies a hazardous substance. The yellow one is telling you that the substance is able to cause combustion. Nitrites have this property. The 5.1 just signifies the hazardous class the material is in. Like a category.
