Super Shock manufacture date

[nikon5400]

I don't know where to post this question, sorry if this is not the place for it. I posted it also in "Bleach Prices 2018", not sure if that's the right place either

Can anyone help me crack this code - 935 01?

I contacted the manufacturer, but they said it's proprietary information

Pool Chlorine - Google Photos

Can it really be up to 17%?

Sodium Hypochlorite 12.5-17 PH 11-14 SDS (revised 91416).pdf - Google Drive

Thanks

I think it's more likely that is a quality control number, with the 935 identifying the line that made it or quality controller who inspected it and the 01 being first shift.

I imagine the date code is elsewhere on the bottle or was on the box it was delivered in.

Yes it can potentially be up to 17% if you purchased it directly from the plant on the day it was manufactured. Unless it was stored under ideal conditions it is probably much closer to 12.5% than 17%.

I get that brand of chlorine from Ocean State Job Lot. That's a lot code. Super Shock doesn't have date codes, either on the bottle or box that I have seen. With the volume of chlorine that OSJL moves, I never had an issue with old chlorine.
