2711.29.00 - Other

This category, HTS 2711.29.00, covers gaseous hydrocarbons that are not natural gas, specifically when they are in a gaseous state. Unlike the sibling category for natural gas (2711.21.00.00), which primarily consists of methane, this classification applies to other distinct gaseous hydrocarbon mixtures or single compounds presented in their gaseous form.

The distinction from natural gas is crucial. While natural gas is predominantly methane, the products classified under 2711.29.00 are generally composed of higher hydrocarbons or specific mixtures thereof. These can include refinery gases or other industrial gaseous hydrocarbon streams that have been separated and purified, and are intended for use as fuels or chemical feedstocks.

Within this category, further subdivisions exist to account for specific types of these other gaseous hydrocarbons. The subcategories typically differentiate based on the primary constituent or the intended application of the gas. For example, specific provisions may exist for propane and butanes, which are common components of liquefied petroleum gases (LPG) when they are presented in their gaseous state. The residual "Other" classification (2711.29.00.60) serves as a catch-all for any remaining gaseous hydrocarbons that do not fit into these more specific sub-classifications.
