It's at $3.84 billion with data reported for January through July 2022. The data are a royal pain to access but I got records for recent months for HS codes 8486, 903082, 903141. There were no records for HS 854311 or 901041. It's possible I exceeded some limit but it seems like there just haven't been those exports yet this year, or else they haven't been reported (yet).
The data I pulled are here: https://docs.google.com/spreadsheets/d/1DUrheqFuEHPKpGU8oaWHYRCYzgR07uNW7rc5pTPLc8E/edit?usp=sharing
