Gaseous Hydrocarbons in the Gaseous State, N.E.S.

Residual gaseous hydrocarbons not elsewhere specified under SITC cover a range of industrial and specialty gas streams that fall outside the named petroleum gas categories. Classification here typically applies to minor-volume or mixed hydrocarbon gases used in chemical feedstock, refrigerant blending, or specialty industrial applications. Importers should confirm HTS alignment carefully, as the boundary between this residual heading and named petroleum gases (such as ethane, propane, or butane) turns on precise chemical composition and physical state at the time of entry.
