HTS chapter 38

HTS chapter 38: miscellaneous chemical products codes and duty rates

Chapter 38 of the Harmonized Tariff Schedule of the United States has 27 headings and 183 rate lines, split into 223 ten-digit statistical codes. Each heading below lists its rate lines with the official description and the general (Column 1) rate of duty. The general rate is only the starting point: Section 301, Section 232 and other programs can add to it depending on the country of origin, and the calculator applies them for any line.
