Last updated: August 2026 dataTetraethyl lead (TEL) and tetramethyl lead (TML) are organo-lead antiknock compounds whose use as gasoline additives has been phased out in most markets under the Clean Air Act and international environmental agreements, leaving residual trade primarily for specialty industrial or research applications. Japan leads US imports under this heading, followed by India and China. EPA regulates these compounds under both TSCA and the Clean Air Act, and importers must be prepared to demonstrate that the intended use does not violate US fuel additive prohibitions.

These compounds are not categorically banned from import, but their use as gasoline additives in on-road vehicles is prohibited under the Clean Air Act. Any import must be for a lawful purpose — such as aviation fuel applications, research, or export — and importers must be able to document the end use. EPA TSCA Section 13 certification is required, and CBP may request additional documentation to confirm the shipment does not violate fuel additive regulations.
Both are organo-lead antiknock agents, but tetraethyl lead (TEL) historically dominated gasoline blending due to its superior octane-boosting efficiency, while tetramethyl lead (TML) was used in blends requiring a different volatility profile. Today, both are largely obsolete for fuel use in developed markets, and remaining trade is concentrated in niche industrial chemistry, calibration standards, and legacy aviation fuel markets.
