How long does Tea last in the pantry once opened?
Turning the range into a date
Tea (bags) keeps 6–12 months in the pantry once opened. Each kind gets its own dated rows here, 6 rows across the 3 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 3 kinds of this separately
The USDA files 3 separate entries under this name — bags, instant and loose — and they do not keep for the same time: Tea, loose holds 2 years outside the freezer, Tea, instant holds 2 years to 3 years. 0 of the 3 carry a freezer figure.
Sealed against opened
Opening the package costs 3 times here: 36 months sealed in the pantry against 12 months open in the pantry. That is a real difference and worth dating the container for, but not the collapse it becomes for the more perishable items in the same list. On the same shelf it sits 3 of 22, between Nutrition supplement drinks at 5 years and White wine at 2 years.

What the USDA adds in words
The USDA attaches 1 handling note to this item, reproduced below word for word. It is not a storage time: it qualifies the figure above rather than replacing it. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
Tea, loose, in the freezer. Matcha tea is the only tea that can be frozen after opening.
Can you freeze tea?
The USDA prints no freezer time for tea. Frozen at 0 °F any food stays safe; whether it is still good after thawing is a matter of quality. Keep the fridge at 40 °F or below and the freezer at 0 °F.
How to tell if tea has gone bad
Go by the date first: tea keeps 6–12 months in the pantry once opened. Unexpected fizzing, cloudiness, floating strands or a sour smell mean it goes out. Once opened, keep it in the fridge at 40 °F or below. Keep the fridge at 40 °F or below and the freezer at 0 °F.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 6 months to 12 months in the pantry once opened. The USDA rating this place at all is the USDA saying Tea, bags keeps there, so the figure rates how good it will be. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
It is past the date. Now what?
Say the calculator above puts Tea, bags past its 6 months to 12 months in the pantry once opened window. Past that the calendar stops deciding and the food itself does. Fizzing that should not be there, cloudiness, floating strands or a sour smell mean it goes out whatever the date says.
The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.

Comparisons and the place in the category are computed for Tea, bags, which is the kind the plain name means here, chosen kind by kind rather than by the order the source happens to list them in.
