I won't report you for this because I guess you are doing with best of faith, given your vital product, which I guess you are not offering for free, so you should know you are risking your profile being deleted by violating Medium TOS, which amongst other things is intended to maintain an ad free environment for ad free dialog. If you and anyone wishing to spam or target ads was to do this and get away with it, we would lose this. In any case I am in no position to purchase anything in supply quantities, so you targeted incorrectly I think.
What you could do without violating any TOS is promote your product in an "educational article" as a standalone article in its own right.
I did follow your website link and was impressed - I didn't know there was different types of Basmati rice, despite being a fan of Basmati rice, it's the only kind I buy for my own use, but in UK there appears no distinction between types, I just get "Laila" Basmati rice in 5kg bags from my local supermarket.
But please, if you want to keep your presence in Medium, you need to avoid spamming or targeting folk with ads.
