Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported primarily as a fuel additive rather than pure chemical
Fuel additives containing organometallic compounds may classify under inorganic compounds if end-use dominates over chemical identity.
If when mixed with other gasoline additives
Antiknock preparations containing tetraethyl lead classify as finished fuel additives rather than pure organo-inorganic compounds.
