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 crucial category of industrial fluids - hydraulic fluids. These specialized liquids play a vital role in the operation of hydraulic systems, which are widely used in various industries, including automotive, construction, and manufacturing. Hydraulic fluids are essential for the efficient and reliable functioning of equipment such as brakes, transmissions, and other hydraulic-powered machinery. This industry's importance extends across multiple sectors, contributing to the broader economic landscape.

The production of hydraulic fluids covered under HS code 381900 typically involves a multi-step process. Manufacturers begin by selecting and blending base oils, which can be derived from petroleum or synthetic sources. These base oils are then combined with various additives, such as anti-wear agents, corrosion inhibitors, and viscosity modifiers, to enhance the fluid's performance characteristics. The resulting mixture is carefully filtered and tested to ensure it meets industry standards and specifications.

The main inputs required for the production of hydraulic fluids under HS code 381900 include base oils, which can be 270900 Petroleum oils and oils obtained from bituminous minerals, crude, as well as a range of specialized additives. Manufacturers also rely on specialized equipment, such as blending tanks, filtration systems, and quality control testing apparatus, to ensure the consistent production of high-quality hydraulic fluids.

The primary output of the industry covered by HS code 381900 is hydraulic fluids, which are used in a wide range of applications. These fluids are consumed by various industries, including 870000 Vehicles other than railway or tramway rolling-stock, and parts and accessories thereof, 842000 Machinery for lifting, handling, loading or unloading, and 848000 Machinery; parts thereof, not specified or included elsewhere in this chapter. The hydraulic fluids produced under this code are essential for the smooth and efficient operation of equipment in these sectors.
