Tetraethyl Lead (TEL)
Tetraethyl lead is a colorless, oily liquid organometallic compound with the formula Pb(C2H5)4, used historically as an antiknock additive in gasoline. It falls under HTS 2931.10.00.00 as a specific organo-inorganic compound where lead is directly linked to carbon atoms, fitting Chapter 29's scope for such compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If mixed with gasoline as antiknock preparation
Blends or preparations containing tetraethyl lead for fuel use shift to Chapter 38 heading for antiknock mixtures, not pure compounds.
If imported as a solution in non-organic solvent for safety
Per Chapter 29 note (e), solutions in solvents solely for safety/transport may classify under inorganic compounds if solvent alters general use suitability.
