3403.19 - Other:

This HTS category, 3403.19, encompasses lubricating preparations that are not specifically designated for the treatment of textile materials, leather, furskins, or other materials. These preparations are designed to reduce friction, prevent wear, and facilitate smooth operation in various mechanical applications. Importantly, this category specifically covers those lubricants that are derived from or contain petroleum oils or oils obtained from bituminous minerals, but they are not preparations where these oils constitute 70 percent or more by weight of the total composition, as such preparations fall under a higher level category.

Unlike its sibling category 3403.11, which focuses on lubricant-based preparations for treating textiles, leather, furskins, or other materials to impart specific properties like water repellency or softness, 3403.19 covers lubricants used in a broader industrial or mechanical context. The distinction lies in the primary function and application: 3403.11 is about surface treatment of specific materials, while 3403.19 is about lubrication in general mechanical systems or as a standalone lubricant.

This category is further subdivided into two subcategories to provide more granular classification based on the concentration of petroleum oils or oils obtained from bituminous minerals. Subcategory 3403.19.10.00 specifically includes preparations where these mineral-derived oils constitute 50 percent or more by weight. Subcategory 3403.19.50.00, conversely, captures all other lubricating preparations within this scope that do not meet the 50 percent threshold for petroleum oils or oils from bituminous minerals, or where other constituents are more dominant.
