If you are maintaining separate parts lists for HTS and Schedule B codes this could be a time saver. Check out the Notice to Exporters on the Harmonized Tariff Schedule (2021 Basic Revision 7).
Exporters may use HTS codes in place of Schedule B. Go to https://hts.usitc.gov/current and choose the view tab. As always, there are exceptions, but you may be able to avoid toggling between lists.
