2710.19.30.80 - Other

This classification, HTS Code 2710.19.30.80, specifically categorizes "Other" lubricating oils and greases, not otherwise specified. These are products derived from petroleum or bituminous minerals, containing at least 70% of such oils and functioning as lubricants, but which do not fit into the more specific subcategories of lubricating oils and greases. The "Other" designation signifies that these are residual items not explicitly defined by the more detailed descriptions of sibling categories.

Distinguishing this category from its siblings, such as aviation engine lubricating oils (2710.19.30.10), automotive diesel or marine engine lubricating oils (2710.19.30.20), turbine lubricating oils (2710.19.30.30), automotive gear oils (2710.19.30.40), and steam cylinder oils (2710.19.30.50), relies on their intended use and specific formulation. If a lubricating oil or grease does not clearly fall under a defined application like aviation, automotive engines, turbines, gears, or steam cylinders, and it meets the general criteria of being a petroleum-based lubricant, it will be classified here.

As a leaf node, this category does not have further subdivisions. Therefore, precise classification into 2710.19.30.80 depends on a thorough review of product specifications, including the base oil composition, additive packages, and the absence of characteristics that would place it into the more narrowly defined sibling categories. This includes a determination that the product is indeed a lubricating oil or grease meeting the 70% petroleum oil threshold, but without a specific, declared primary function that aligns with the preceding subheadings.
