Analysis
Subheading 2901.10 covers saturated, within heading 2901. 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 4 US tariff lines below it are national.
Every one of its 4 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.
The US splits it as follows: 2901.10.10 for saturated: ethane and butane (duty-free), 2901.10.30 for n-Pentane and isopentane (duty-free), 2901.10.40 for derived in whole or in part from petroleum, shale oil or natural gas (duty-free) and 2901.10.50 for other: other (duty-free).
By Census's concordance, most of its statistical lines are made by Petrochemical Manufacturing (325110) and All Other Basic Organic Chemical Manufacturing (325199). Those are the NAICS industries a US producer of these goods would report under.
