Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for gasoline rather than other oils
Specific subheading for antiknock preparations explicitly for gasoline engines.
If imported as pure tetraethyllead chemical
Organolead compounds in bulk chemical form fall under organo-inorganic compounds heading.
If containing biodiesel components
Biodiesel-mixed fuel additives may classify under preparations containing biodiesel.

Import Tips & Compliance
• Ensure end-use certification for exempt applications like aviation to bypass road fuel bans
• Comply with IMDG/ADR hazardous goods declarations due to high toxicity of lead compounds
• Monitor REACH-like restrictions in destination markets for lead additives

Tetraethyllead (TEL) Antiknock Additive
Tetraethyllead (TEL) is a classic organolead compound used as an antiknock agent in gasoline engines to prevent engine knocking by increasing octane rating. This prepared additive falls under HTS 3811.11.5000 as it is based on lead compounds and classified as 'other' antiknock preparations for mineral oils like gasoline. It was widely used in leaded gasoline formulations before regulatory phase-outs.
Aviation Leaded Antiknock Mixture
Specialized antiknock preparation with lead compounds for 100LL avgas (low-lead aviation gasoline) to suppress detonation in piston aircraft engines. HTS 3811.11.5000 covers this as 'other' lead-based antiknock for mineral oils used in hydraulic or lubricating purposes akin to gasoline.
