Hydraulic fluids; for brakes and other prepared liquids for hydraulic transmission, not containing or containing less than 70% by weight of petroleum oils or oils obtained from bituminous minerals

HS code 381900 covers a range of hydraulic fluids and prepared liquids used in hydraulic transmission systems, such as those found in vehicle brakes and other industrial applications. These fluids play a crucial role in the smooth and efficient operation of various mechanical systems, ensuring the transfer of power and the prevention of wear and tear. As a key component in many industries, the production and trade of these specialized liquids are integral to the broader economy.

The production of hydraulic fluids covered under HS code 381900 typically involves the blending and formulation of various base oils, additives, and other chemical compounds. Manufacturers carefully select and combine these ingredients to achieve the desired properties, such as viscosity, lubricity, and corrosion resistance. The mixing and blending process is often carried out in controlled environments to ensure consistent quality and performance of the final product.

The main inputs required for the production of hydraulic fluids under HS code 381900 include base oils, which can be derived from petroleum or synthetic sources, as well as a range of additives such as anti-wear agents, anti-foaming agents, and viscosity modifiers. Specialized production equipment, such as blending tanks, filtration systems, and packaging machinery, are also essential for the manufacturing process.

The primary output of HS code 381900 is a diverse range of hydraulic fluids and prepared liquids for use in various hydraulic systems, including those found in vehicles, industrial machinery, and other applications. These fluids are often consumed by manufacturers and service providers in the 870000 Motor vehicles, parts and accessories and 842000 Machinery and mechanical appliances; parts thereof industries, among others.
