3403.19.50.00 - Other

This HTS category, 3403.19.50.00, encompasses "Other" lubricating preparations that contain petroleum oils or oils obtained from bituminous minerals. These preparations are specifically excluded from the main heading of "Lubricating preparations" if they contain 70 percent or more by weight of such oils. This subcategory is for those lubricating preparations containing petroleum oils or oils obtained from bituminous minerals, where the oil content is less than 70 percent by weight, but greater than or equal to 50 percent by weight, as described in the sibling category.

To further clarify, the distinction lies in the precise percentage of petroleum oils or oils obtained from bituminous minerals by weight. While 3403.19.10.00 covers preparations with 50 percent or more of these oils, this "Other" category captures those falling within the range of 50 percent to just under 70 percent. This ensures that preparations with a significant but not dominant proportion of these mineral oils are correctly classified.

As this is a leaf node in the HTS classification system, there are no further subcategories to introduce. The classification of a product into this category is final at this level, based on its composition meeting the criteria of containing petroleum oils or oils obtained from bituminous minerals in the specified weight range and not otherwise meeting the exclusions or specific definitions of sibling categories. Examples include specialized greases, certain industrial lubricants, or polishes with a lubricant base where the mineral oil content falls within this specific percentage band.
