Import Tips & Compliance
• Ensure the product is certified as a separate chemically defined compound with a Certificate of Analysis to support classification under 2931.10.00
• Declare the end-use (research or calibration) to CBSA, as this may affect documentation requirements
• Verify that no stabilizers or solvents are added, as those could change the tariff classification

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 in Safety Solvent
Tetraethyl lead dissolved in a non-reactive safety solvent, such as a hydrocarbon, for safe transport and handling. The solvent is necessary solely for safety reasons and does not make the product suitable for a specific use, aligning with Chapter 29 Note 1(e). This organo-inorganic compound falls under tariff item 2931.10.00 as a tetramethyl or tetraethyl lead compound.
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.
