TEL-TML Mixture Aviation Fuel Booster
A prepared additive blending tetraethyl lead (TEL) and tetramethyl lead (TML) to boost octane in 100LL avgas for piston aircraft. Classified under HTS 3811.11.1000 due to its basis on the specified lead compounds for anti-knock performance in mineral oil-based fuels. Essential for legacy aircraft engines requiring high-octane protection.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If antiknock based on non-lead organometallic compounds like MMT
Other antiknock preparations not based on lead compounds are classified separately under the non-lead subheading.
If imported as a pure organo-lead chemical rather than formulated additive
Unformulated tetraethyl lead as a separate chemical falls under Chapter 29 for organo-inorganic compounds.
If contaminated with listed persistent organic pollutants
Mixtures containing specific hazardous substances like DDT trigger reclassification under 3824.81 for waste-like preparations.

Import Tips & Compliance
• Comply with TSCA import notifications for lead compounds; use UN-approved containers for toxic liquid shipping; test for exact TEL/TML ratio to confirm subheading
