2711.13.00 - Butanes

This HTS category, 2711.13.00, specifically covers butanes when they are in a liquefied state. Butanes are a group of saturated hydrocarbons with the formula C4H10, commonly known for their use as fuels. This classification applies to these specific hydrocarbons, regardless of their intended end-use, provided they meet the criteria of being liquefied petroleum gases.

It is important to distinguish this category from its siblings. Unlike 2711.11.00.00 (Natural gas) or 2711.12.00 (Propane), this category is exclusively for butanes. It also differs from 2711.14.00, which covers unsaturated hydrocarbons like ethylene, propylene, butylene, and butadiene, and from 2711.19.00 which is a residual category for other liquefied gaseous hydrocarbons. The defining characteristic here is the chemical composition of butanes.

Within the broader category of butanes (2711.13.00), further subdivisions exist to account for variations in purity. Subcategory 2711.13.00.10 applies to butanes with a purity level ranging from 90% to less than 95% by liquid volume. Subcategory 2711.13.00.20 then covers all other butanes, effectively acting as a residual category for those not meeting the specific purity threshold of the preceding subcategory. These distinctions are crucial for accurate tariff assessment.
