Analysis
Subheading 2841.50 covers other chromates and dichromates; peroxochromates, within heading 2841. 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 1.5% to 3.1% with a median of 2.3%, so the line you choose sets the duty.
The US splits it as follows: 2841.50.10 for potassium dichromate (1.5%) and 2841.50.91 for other chromates and dichromates; peroxochromates: other (3.1%).
By Census's concordance, most of its statistical lines are made by Other Basic Inorganic Chemical Manufacturing (325180). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 2841.50 once they fall within heading 2841 (salts of oxometallic or peroxometallic acids). 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.
