Analysis
Subheading 1005.90 covers other, within heading 1005. 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: 1005.90.20 for other: yellow dent corn (0.05¢/kg) and 1005.90.40 for other: other (0.25¢/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 Corn Farming (111150) and All Other Miscellaneous Food Manufacturing (311999). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 1005.90 once they fall within heading 1005 (corn (maize)). 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.
