Analysis
Subheading 4012.12 covers of a kind used on buses or trucks, within heading 4012. 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.
None of its 2 lines is duty-free at the general rate. Rates run from 3.4% to 4% with a median of 3.7%, so the line you choose sets the duty.
The US splits it as follows: 4012.12.40 for of a kind used on buses or trucks: radial (4%) and 4012.12.80 for of a kind used on buses or trucks: other (3.4%).
By Census's concordance, most of its statistical lines are made by Tire Retreading (326212). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 4012.12 once they fall within heading 4012 (retreaded or used pneumatic tires of rubber; solid or cushion tires, tire treads and tire…). 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.
