Analysis
Subheading 8511.90 covers parts, within heading 8511. 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 3 US tariff lines below it are national.
1 of its 3 lines with a percentage rate are duty-free at the general rate (33%) and 2 are dutiable, from duty-free up to 3.1%. The median line pays 2.5%.
The US splits it as follows: 8511.90.20 for designed for use on 6, 12 or 24 V systems (3.1%), 8511.90.40 for of voltage and voltage-current regulators with cut-out relays: other (duty-free) and 8511.90.60 for parts: other parts (2.5%).
By Census's concordance, most of its statistical lines are made by Motor Vehicle Electrical and Electronic Equipment Manufacturing (336320). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 8511.90 once they fall within heading 8511 (electrical ignition or starting equipment of a kind used for spark-ignition or…). 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.
