I am a Brazilian with a Portuguese resident authorization.
I will visit my hometown in Rio Grande do Sul state and I would like to bring a kind of tea (Chimarrão tea) to here. As I will have a bunch of slots in my baggage, I would like to bring 12KG of tea. I consume almost 2KG by month, so, I will have tea for 6 months. The tea is not illegal and it can be bought in Portugal, but it so expensive.
I am checking this page and it says that I cannot bring goods in quantities greater than those permitted. However, I did not find what is the permitted quantities (I found only for alcohol). I know that in Brazil, usually the quantity as 12.
What is the permitted quantity in Portugal?
