Products classified under HTS 3811.11.10.00
Tetraethyl Lead Gasoline Antiknock Additive
A lead-based antiknock preparation containing tetraethyl lead for enhancing octane ratings in aviation gasoline. It falls under HTS 3811.11.1000 as it is specifically based on tetraethyl lead, used to prevent engine knocking in high-performance piston aircraft engines. Primarily used in general aviation where unleaded alternatives are not yet universal.
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.
Classic Car TEL Octane Improver
Tetraethyl lead-based additive designed for vintage and classic car engines using leaded gasoline formulations. It qualifies for HTS 3811.11.1000 as an antiknock preparation based on tetraethyl lead for mineral oils like gasoline. Used by restorers to mimic original fuel performance and prevent valve damage.
TEL Lead Additive for Racing Fuels
High-concentration tetraethyl lead additive for drag racing and motorsport fuels requiring extreme octane levels. Falls under HTS 3811.11.1000 for its tetraethyl lead base in antiknock preparations for gasoline. Provides detonation control in high-compression race engines.
Aviation 100LL TEL Antiknock Compound
Specialty compound of tetraethyl lead for 100LL low-lead aviation gasoline production. Classified in HTS 3811.11.1000 as it matches the exact description for TEL-based antiknock preparations for mineral oils. Critical for maintaining consistent blue-dyed avgas specifications.
Vintage Engine TEL Fuel Treatment
Tetraethyl lead treatment for restoring performance in pre-1970s automobile engines. It is based on TEL for antiknock in gasoline, fitting HTS 3811.11.1000 precisely. Helps prevent pinging in high-compression classic motors.
