Analysis
HTS 2711.11.00 covers liquefied: natural gas under heading 2711 (petroleum gases and other gaseous hydrocarbons).
The normal trade relations rate here is zero, shared by about 89% of the 46 tariff lines in chapter 27, a useful check when a neighbouring dutiable line is a candidate. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.
Census statistics map these goods to NAICS 211130 (Natural Gas Extraction), an industry of 1,342 US establishments employing 27,601 people. That concordance is how imports of this line are compared with US output.
All 6 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
