Analysis
Subheading 8607.29 covers other, within heading 8607. 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 2.6% to 3.6% with a median of 3.1%, so the line you choose sets the duty.
The US splits it as follows: 8607.29.10 for for vehicles of heading 8605 or 8606 (3.6%) and 8607.29.50 for other: other (2.6%).
By Census's concordance, most of its statistical lines are made by Railroad Rolling Stock Manufacturing (336510). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 8607.29 once they fall within heading 8607 (parts of railway or tramway locomotives or rolling stock). 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.
