I am Brazilian with a Portuguese resident permit.
I will visit my hometown in the state of Rio Grande do Sul and I would like to bring some kind of tea (Chimarrão tea) here. As I am going to have a bunch of slots in my luggage, I would like to bring 12 kg of tea. I consume nearly 2 kg per month, so I will have tea for 6 months. Tea is not illegal and it can be bought in Portugal, but it is so expensive.
I check this page and it is said that I can not bring goods in quantities greater than those authorized. However, I did not find what quantities are allowed (I found only for alcohol). I know that in Brazil, usually the amount of 12.
What is the authorized quantity in Portugal?
