What is this HS code?
HS 9030.40.00.00 is the HTS line for Other instruments and apparatus, specially designed for telecommunications (for example, cross-talk meters, gain measuring instruments, distortion factor meters, psophometers). The base duty comes from the USITC HTS source field; final filing still depends on product specs, origin, special programs, Chapter 99, and broker review.
