2917
Polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives
Analysis
Heading 2917 of the Harmonized Tariff Schedule covers polycarboxylic acids, their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives. It divides into 13 six-digit subheadings and 32 eight-digit tariff lines, with 36 ten-digit statistical suffixes below them.
The spread of 6.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.5%, applies to 2917.12.10 (adipic acid, its salts and esters: adipic acid) and 2917.12.20 (other: plasticizers).
3 of its 32 lines with a percentage rate are duty-free at the general rate (9%) and 29 are dutiable, from duty-free up to 6.5%. The median line pays 6.5%.
Its median rate of 6.5% sits at the 83rd percentile of the headings in chapter 29.
The largest subheadings are 2917.19 (other, 10 lines), 2917.39 (other, 8 lines), 2917.12 (adipic acid, its salts and esters, 3 lines) and 2917.14 (maleic anhydride, 2 lines).
By Census's concordance, most of its statistical lines are made by All Other Basic Organic Chemical Manufacturing (325199) and Cyclic Crude, Intermediate, and Gum and Wood Chemical Manufacturing (325194). Those are the NAICS industries a US producer of these goods would report under.
