Anecdotal self-answer
We decided to bring the tea bags with us. Coincidentally we were selected for a bag search while going through customs and the customs officer wasnβt the least bit interested in the tea bags and let us through after little more than a cursory search.
As such it would seems itβs perfect acceptable and weβre glad we brought them as the tea here is Lipton.

I took tea with me to mexico in 2010 and in 2015. My bag was selected and searched. The Officer found tea bags and asked whether this was tea (I use Twinings large square tea bags with not tag and I did not have original packaging). It was fine.
