Base HTS information
This section only publishes base HTS information with source fields attached. Base HTS and additional-duty review work stay separate so the page does not overstate unsupported composite estimates.
HTS general rate field: The duty provided in the applicable subheading + 15%
Rate-output note: only the base HTS field is shown here. Additional duties, Chapter 99 treatment, exclusions, or AD/CVD still require separate review.
