Analysis
Subheading 2921.41 covers aniline and its salts, within heading 2921. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 2 US tariff lines below it are national.
None of its 2 lines is duty-free at the general rate. Rates run from 6.5% to 6.5% with a median of 6.5%, so the line you choose sets the duty.
The US splits it as follows: 2921.41.10 for aniline and its salts: aniline (6.5%) and 2921.41.20 for aniline and its salts: aniline salts (6.5%).
By Census's concordance, most of its statistical lines are made by Cyclic Crude, Intermediate, and Gum and Wood Chemical Manufacturing (325194). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 2921.41 once they fall within heading 2921 (amine-function compounds). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
