Analysis
Subheading 3606.90 covers other, within heading 3606. 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.
1 of its 3 lines with a percentage rate are duty-free at the general rate (33%) and 2 are dutiable, from duty-free up to 5.9%. The median line pays 5%.
The spread of 5.9 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 5.9%, applies to 3606.90.30 (ferrocerium and other pyrophoric alloys).
The US splits it as follows: 3606.90.30 for ferrocerium and other pyrophoric alloys (5.9%), 3606.90.40 for other: metaldehyde (duty-free) and 3606.90.80 for other: other (5%).
By Census's concordance, most of its statistical lines are made by All Other Miscellaneous Chemical Product and Preparation Manufacturing (325998). Those are the NAICS industries a US producer of these goods would report under.
