Analysis
Heading 2921 of the Harmonized Tariff Schedule covers amine-function compounds. It divides into 18 six-digit subheadings and 65 eight-digit tariff lines, with 76 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 2921.14.00 (2-(N,N,-Diisopropylamino)ethyl chloride…) and 2921.19.61 (other: other).
14 of its 65 lines with a percentage rate are duty-free at the general rate (22%) and 51 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 2921.42 (aniline derivatives and their salts, 11 lines), 2921.43 (toluidines and their derivatives; salts thereof, 8 lines), 2921.49 (other, 7 lines) and 2921.59 (other, 7 lines).
By Census's concordance, most of its statistical lines are made by Cyclic Crude, Intermediate, and Gum and Wood Chemical Manufacturing (325194), All Other Basic Organic Chemical Manufacturing (325199) and Synthetic Dye and Pigment Manufacturing (325130). Those are the NAICS industries a US producer of these goods would report under.
