Product of Pakistan or produce of pakistan or produced in Pakistan?

[IAJ]

I often read this sentence on the mango boxes or pickle bottles:

-Produce of Pakistan

Is this a right term? I mean the word Produce, isn't it a verb? Shouldn't it be called either Product of Pakistan or produced in Pakistan

Thanks in advance.

"produce of" is a term strictly used for vegetable/ fruits which grow in a certain country(place). However, you can't use this term for any other item.
