Anti-knock preparations; based on lead compounds

HS v2022 Code: 381111

About anti-knock preparations; based on lead compounds

HS code 381111 covers anti-knock preparations based on lead compounds. These products play a crucial role in the automotive industry, where they are used as fuel additives to improve engine performance and prevent knocking or premature detonation of the fuel-air mixture. Anti-knock preparations help ensure efficient and reliable engine operation, contributing to the overall performance and longevity of vehicles. This industry is an essential component of the broader transportation and logistics sectors, supporting the smooth functioning of global supply chains.

Production process

The production of anti-knock preparations based on lead compounds typically involves a multi-step process. First, the lead compounds, such as tetraethyllead or tetramethyllead, are synthesized through chemical reactions. These lead-based compounds are then blended with other additives, such as solvents and dispersants, to create the final anti-knock preparation. The mixing and blending processes are carefully controlled to ensure the desired properties and performance characteristics of the final product.

Production inputs

The main inputs required for the production of HS code 381111 anti-knock preparations include lead compounds, solvents, dispersants, and other specialized chemical additives. Additionally, the industry relies on specialized production equipment, such as reactors, mixers, and blending tanks, to facilitate the manufacturing process. The availability and quality of these raw materials and production resources are crucial for the industry to meet the demand for effective anti-knock preparations.

Production outputs

The primary output of HS code 381111 is anti-knock preparations based on lead compounds, which are primarily consumed by the 870000 Motor vehicles, trailers and semi-trailers industry as fuel additives. These anti-knock preparations help improve engine performance, reduce emissions, and extend the lifespan of automotive engines. The outputs of this industry may also be used in other applications, such as 271000 Mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes or 382000 Miscellaneous chemical products.
