Related Products under HTS 2931.10.00.00

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.

Tetramethyl Lead (TML)

Tetramethyl lead is a liquid organolead compound with formula Pb(CH3)4, serving as an antiknock agent similar to TEL but with methyl groups. Classified under HTS 2931.10.00.00 as it is explicitly named in the heading for organo-inorganic compounds with direct C-Pb bonds.

Tetraethyl Lead with Stabilizer

Tetraethyl lead stabilized with an anticaking agent for safe storage and transport, maintaining chemical purity. It qualifies under HTS 2931.10.00.00 per Chapter 29 note (f) allowing stabilizers necessary for preservation without changing classification.

High-Purity Tetraethyl Lead (99.99%)

Ultra-pure tetraethyl lead for research or calibration standards, free of impurities as a separate chemically defined compound. Falls precisely under HTS 2931.10.00.00 meeting Chapter 29 note (a) for pure organic compounds.

Tetraethyl Lead in Safety Solvent

Tetraethyl lead dissolved in a non-reactive solvent for safe transport, where solvent use is necessary per safety standards. Classified under HTS 2931.10.00.00 via Chapter 29 note (e) as long as not suited for specific use.

Tetramethyl Lead Research Grade

Research-grade tetramethyl lead with added identification coloring for lab safety, chemically defined per note (g). Remains under HTS 2931.10.00.00 as the color facilitates identification without specific use adaptation.
