My best guess is that CBP will use the 2023 CFR and the 2024 HTS. Yes, I could be wrong, but lets see. CBP should issue the exam announcement in June sometime. Also, I am guessing CBP will keep Parts 200 to end of the regulations on the exam. I kind of nailed that one for my students. I assumed CBP would test the same thing they tested in 2015 to 2017… and they did!
