HS Code for Fuel octane booster

3811.19 Anti-knock preparations; other than those based on lead compounds
Chemicals
View full HS code details

Fuel octane boosters are classified under HS code 3811.19. This classification is determined by the chemical nature of the product as an anti-knock preparation. Heading 3811 covers anti-knock preparations, oxidation inhibitors, gum inhibitors, viscosity improvers, anti-corrosive preparations, and other prepared additives for mineral oils. Octane boosters are specifically designed to increase the octane rating of gasoline to prevent engine knocking or pre-ignition. Subheading 3811.11 is reserved for preparations based on lead compounds (such as tetraethyl lead). Since modern consumer octane boosters are almost exclusively lead-free, utilizing chemicals like MMT (Methylcyclopentadienyl manganese tricarbonyl), aromatic alcohols, or ethers, they fall under the 'other' category of 3811.19. The classification is based on the functional purpose of the additive and its chemical composition as a preparation rather than a single chemically defined element or compound.

Products Included

  • MMT-based octane boosters
  • Lead-free anti-knock additives
  • Racing fuel concentrates (non-lead)
  • Performance fuel additives for octane enhancement
  • Aromatic hydrocarbon-based fuel boosters

Common Misclassification

Octane boosters are often misclassified under HS code 3811.90, which is a residual category for 'other' fuel additives like detergents or cetane improvers. However, because octane boosters are specifically 'anti-knock' preparations, they must be classified under 3811.1x. Another common error is attempting to classify these products under 2710.12 if they are heavily diluted with petroleum spirits; however, if the product is marketed and used as an additive rather than a fuel, Chapter 38 is the correct location. Lead-based boosters are also sometimes incorrectly placed here instead of 3811.11.
