Analysis
Subheading 3802.90 covers other, within heading 3802. 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 3 US tariff lines below it are national.
None of its 3 lines is duty-free at the general rate. Rates run from 2.5% to 5.8% with a median of 4.8%, so the line you choose sets the duty.
The US splits it as follows: 3802.90.10 for other: bone black (5.8%), 3802.90.20 for activated clays and activated earths (2.5%) and 3802.90.50 for other: other (4.8%).
By Census's concordance, most of its statistical lines are made by Synthetic Dye and Pigment Manufacturing (325130) and Ground or Treated Mineral and Earth Manufacturing (327992). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 3802.90 once they fall within heading 3802 (activated carbon; activated natural mineral products; animal black, including spent…). 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.
