All official links I can find are in Spanish.
I’d like to take some tea bags to Mexico, is this allowed and do I have to declare them?
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 wasn’t the least bit interested in the tea bags and let us through after little more than a cursory search.
As such it would seems it’s perfect acceptable and we’re glad we brought them as the tea here is Lipton.
