If the output is a crate, deliver it to a base and submit it to unpack individual items. For further production, materials must be in the form accepted by the recipe.

Where to deliver finished crates

Submit to a base — unpack for players

Drive to the base and open its menu with E, right-click the crate in your inventory and choose Submit to Stockpile. For all crates, use Submit All to Stockpile. The crates unpack and their contents enter the base’s public stockpile.

Store at a depot or seaport

In Storage Depot or Seaport crates remain packed. For Legion supplies, open the correct Reserve Stockpile using its code. Before submitting, make sure you selected it rather than the public stockpile. Only crates marked Reservable may enter a reserve: check the item tooltip. Reserves expire, so monitor and refresh their timers.

Submitting to public stock irreversibly removes reservability. The crate becomes public. You can retrieve it, but cannot put it in a private stockpile again, even at another depot. Check the selected stockpile before submitting.

Sources: submitting to bases, crates, reservability. Vehicle crates use separate unpacking rules; the instructions above concern item crates.
