Heading 2918 covers carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives. It splits into 11 six-digit subheadings and 4 US tariff lines, 0 of which are duty-free under the general rate.
Headings are the four-digit level of the Harmonized System — the layer that is identical across all 160-plus countries that use it. The six-digit subheading is also international; the last two digits of each code here are US-specific and do not carry across to another country's tariff.
