2711.11.00.00 - Natural gas

This HTS category, 2711.11.00.00, specifically classifies "Natural gas" when it is in a liquefied form. Natural gas is a complex mixture primarily composed of methane, along with varying amounts of other hydrocarbons like ethane, propane, and butane, as well as non-hydrocarbon gases such as nitrogen and carbon dioxide. Its classification under "Petroleum gases and other gaseous hydrocarbons, liquefied" signifies its transformation into a liquid state for easier storage and transportation.

Distinguishing this category from its siblings is crucial for accurate classification. While 2711.12.00 covers liquefied propane, 2711.13.00 covers liquefied butanes, and 2711.14.00 encompasses liquefied ethylene, propylene, butylene, and butadiene, this code is reserved for the mixture typically known as natural gas. The key difference lies in the composition: natural gas is a naturally occurring mixture, whereas the sibling categories are typically pure or specific hydrocarbon compounds, often produced through refining processes. 2711.19.00 serves as a residual category for other liquefied gaseous hydrocarbons not specifically listed.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 2711.11.00.00 relies on confirming the imported commodity is indeed liquefied natural gas based on its primary composition and origin, distinguishing it from liquefied individual hydrocarbons or other gaseous mixtures.
