Its the trade off between insurance value and the declare value. In this case, I don't think a tong of tea would be damaged, so you know what to do
The key is not to use EMS though. For EMS and over $30, and you would almost certainly have to pay import tax at the rate I mentioned previously for tea, unless you are lucky.
If you are unlucky enough, your tea might got inspected by the custom, as it is apparently not legal to import tea without some official papers. This is very true with teas from India.
