Analysis
Subheading 4013.90 covers other, within heading 4013. 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.
1 of its 2 lines with a percentage rate are duty-free at the general rate (50%) and 1 are dutiable, from duty-free up to 3.7%. The median line pays 1.85%.
The US splits it as follows: 4013.90.10 for designed for tires provided for in subheadings 4011.70.00… (duty-free) and 4013.90.50 for other: other (3.7%).
By Census's concordance, most of its statistical lines are made by Tire Manufacturing (except Retreading) (326211). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 4013.90 once they fall within heading 4013 (inner tubes, of rubber). 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.
