Tetraethyl Lead (TEL) from Japan

Tetraethyl lead is an organo-inorganic compound where lead atoms are directly linked to carbon in ethyl groups, used historically as an antiknock additive in gasoline. It falls under HTS 2931.90.90 as 'other organo-inorganic compounds' since it contains a metal (lead) directly bonded to carbon and doesn't fit specific subheadings. The chapter notes confirm classification in heading 2931 for such metal-carbon bonded compounds.
