will sn be affected by cold while being transported to canada

[aramir]

I ordered SN a while ago from europe and I read somewhere that cold temperatures can affect what we want to do with it. I'm just worried about what will happen during transportation since canada's weather this time of year is pretty cold and obviously storage facilities for random parcels are probably not heated not to mention if it came by plane then temperatures will be much colder at higher altitudes . can anyone tell me if I need to worry about this or not ? Thanks.

TL;DR – Temp affects solution potency over time. Solid, air-tight, without moisture – should be fine. Has nothing to react with :)

Reactive substances have specific temp indication for reaction. Lacking those means "ok". SN (packed) mentioned only with regards to high heat, reagents, pressure, and combustion. Commercial SN for industrial use is transported in trucks/airplanes , neither heated nor cooled ...

"Keep away from heat, sparks, and flame. Do not store near combustible materials. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do not expose to air. Store protected from moisture. Store under an inert atmosphere."

"Keep/Store away from extremely high or low temperatures and incompatible materials".

I got mine in the middle of winter, and it was fine. But do not open the container. Moisture from the air made it crunchy which a sign of nitrate as opposed to the nitrite it started out as. Did get another bottle...
