Analysis
Subheading 1003.90 covers other, within heading 1003. 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.
The US splits it as follows: 1003.90.20 for for malting purposes (0.1¢/kg) and 1003.90.40 for other: other (0.15¢/kg).
2 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 All Other Grain Farming (111199). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 1003.90 once they fall within heading 1003 (barley). 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.
