Products classified under Tariff item 2931.10.00
High-Purity Tetraethyl Lead (99.99%)
High-purity tetraethyl lead (99.99%) is a separate chemically defined organo-inorganic compound, explicitly named in tariff item 2931.10.00. It is imported for research or calibration standards, meeting Chapter 29 note 1(a) as a pure compound without impurities that alter its general use.
Industrial Tetraethyl Lead Concentrate
Industrial tetraethyl lead concentrate is a chemically defined organo-inorganic compound used for fuel blending. It falls under tariff item 2931.10.00 as the named compound, provided it is not put up in a form for retail sale or mixed with other substances that would change its classification.
Stabilized Tetramethyl Lead for Transport
Stabilized tetramethyl lead for transport includes a stabilizer necessary for preservation or transport, as allowed by Chapter 29 note 1(f). The product remains a separate chemically defined compound under tariff item 2931.10.00, as the stabilizer does not render it suitable for a specific use.
Tetraethyl Lead Anti-Dusting Formulation
Tetraethyl lead anti-dusting formulation contains a minimal anti-dusting agent added for safety, as permitted by Chapter 29 note 1(g). The product is classified under tariff item 2931.10.00 because the addition does not make it particularly suitable for a specific use beyond general handling.
Tetraethyl Lead Calibration Standard
Tetraethyl lead calibration standard is a certified analytical standard, often dissolved in water or another solvent for use in spectroscopy. It falls under tariff item 2931.10.00 as a separate chemically defined compound, provided the solvent is for safety or transport and not for a specific analytical use.
Tetraethyl Lead (TEL)
Tetraethyl lead (TEL) is a colorless, oily liquid organometallic compound with the formula Pb(C2H5)4, historically used as an antiknock additive in gasoline. It is explicitly named in tariff item 2931.10.00 and qualifies as a separate chemically defined organo-inorganic compound under Chapter 29.
Tetraethyl Lead with Stabilizer
Tetraethyl lead with stabilizer includes an anticaking agent necessary for preservation or transport, as allowed by Chapter 29 note 1(f). The product remains classified under tariff item 2931.10.00, as the stabilizer does not alter its general use or make it suitable for a specific application.
Tetramethyl Lead Research Grade
Research-grade tetramethyl lead with added identification coloring for lab safety is classified under tariff item 2931.10.00. The colouring substance is added for safety reasons, as permitted by Chapter 29 note 1(g), and does not render the product suitable for a specific use.
Tetramethyl Lead (TML)
Tetramethyl lead (TML) is a liquid organolead compound with the formula Pb(CH3)4, used as an antiknock agent. It is explicitly named in tariff item 2931.10.00 and qualifies as a separate chemically defined organo-inorganic compound under Chapter 29.
