Export Item... and Create Bibliography From Item... do not generate equivalent BibTeX
Example (both have been reformatted with emacs bibtex-mode M-x bibtex-reformat)
First Export -> Bibtex
@article{tollestrup_congressional_2012,
title = {The Congressional appropriations process: An introduction},
volume = 23,
url =
{https://www.wisconsin.edu/government-relations/download/The-Congressional-Appropriations-Process-An-Introduction.pdf},
shorttitle = {The Congressional appropriations process},
pages = {R42388},
journaltitle = {Congressional Research Service, February},
author = {Tollestrup, Jessica},
urldate = {2017-10-02},
date = 2012,
file = {The Congressional Appropriations Process\: An
Introduction:/Users/gla/Zotero/storage/WTA94DRM/The
Congressional Appropriations Process An
Introduction.pdf:application/pdf}
}
Second Create -> Bibtex

Several fields are missing for the latter. It is often more convenient to "Create" a bibliography and then paste the bibtex into a file for specific references, rather than "Export" a file and merge the new exports into the existing .bib. It seems like both commands should produce the same output.

This is an old discussion that has not been active in a long time. Before commenting here, you should strongly consider starting a new discussion instead. If you think the content of this discussion is still relevant, you can link to it from your new discussion.
However: you should be able to select the export style for "quick copy" and copy/paste using that instead. It won't handle citekey collisions, but will get you everything else you're interested in.
