Tetraethyl Lead (TEL)
Tetraethyl lead (TEL) is an organolead compound used primarily as an antiknock additive in aviation gasoline for piston-engine aircraft. It is classified here as an ester of an inorganic acid of a non-metal (ethanol with lead acid), with its lead atom directly linked to carbon. Importation is strictly controlled in Canada due to environmental and health regulations.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is presented as a tetramethyl lead or other lead-containing organo-inorganic compound not covered by the ester description
Heading 29.31 covers other organo-inorganic compounds, including lead alkyls, when they do not meet the ester definition of heading 29.20.
If imported as a prepared additive for gasoline, already formulated with solvents or other components
Prepared antiknock additives based on lead compounds are classified in heading 38.11, which is more specific than the pure compound.

Import Tips & Compliance
• Tetraethyl lead is subject to the Canadian Environmental Protection Act, 1999; you may need a permit from Environment and Climate Change Canada before CBSA will release the goods
• Verify whether your end-use (e.g
• aviation fuel additive) qualifies for any regulatory exemptions
• Declare the exact concentration and purity on the commercial invoice to support classification under this item
