Analysis
Subheading 9109.90 covers other, within heading 9109. 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.
The US splits it as follows: 9109.90.20 for measuring not over 50 mm in width or diameter (20¢ each), 9109.90.40 for valued not over $5 each (15¢ each + 6.4%) and 9109.90.60 for valued over $5 each (30¢ each + 4.3%).
3 of the lines carry specific or compound rates (per kilogram, per dozen and so on) rather than a percentage, so their burden depends on the unit value of the goods.
By Census's concordance, most of its statistical lines are made by Other Measuring and Controlling Device Manufacturing (334519). Those are the NAICS industries a US producer of these goods would report under.
