Analysis
Heading 2711 of the Harmonized Tariff Schedule covers petroleum gases and other gaseous hydrocarbons. It divides into 7 six-digit subheadings and 7 eight-digit tariff lines, with 17 ten-digit statistical suffixes below them.
Every one of its 7 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.
The largest subheadings are 2711.11 (unnamed, 1 line), 2711.12 (unnamed, 1 line), 2711.13 (unnamed, 1 line) and 2711.14 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Natural Gas Extraction (211130) and Petrochemical Manufacturing (325110). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of duty-free sits at the 45th percentile of the headings in chapter 27.
The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
