Do these specifications for SN sound good?

[everythingoes]

This is from a Chinese source. It would cost me £140 which I know is expensive, especially considering how cheap SN actually is, but I'm kind of desperate and I can't seem to find anything else. There's still a few months until I plan to CTB, so I'll keep looking, but I want to know if these specifications sound like good SN.

Sodium Nitrite CAS 7632-00-0
CAS NO: 7632-00-0

NNaO2 and NaNO are both acceptable ways of expressing the chemical formula. Yes, >/= 99% is the purity and is good since it is better than 95%. If you get it, it should still be tested to ensure you have what they said it is.
