2710.19.30 - Oils

This category, HTS Code 2710.19.30, encompasses a range of lubricating oils and greases that are not specifically classified elsewhere. These products are derived from petroleum or bituminous minerals and are formulated to reduce friction and wear between moving parts in various machinery and engines. The "Other" designation indicates that these lubricants do not fall into more specific subcategories like aviation engine oils, automotive engine oils, or turbine oils, which are detailed in the subcategories below.

At this level of the Harmonized Tariff Schedule, the primary sibling category is "Greases." While both lubricating oils and greases are designed for lubrication, greases are typically semi-solid or solid, whereas this category specifically covers the liquid lubricating oils. The distinction is crucial for accurate classification, relying on the physical state and viscosity of the product.

The subcategories within 2710.19.30 provide a detailed breakdown of specific types of lubricating oils based on their intended application and formulation. These include oils for aviation engines, automotive and marine engines, turbines, automotive gears, steam cylinders, and specialized quenching or cutting oils. The final subcategory, "Other," is reserved for lubricating oils that do not fit into these more defined applications, ensuring comprehensive coverage within the broader scope of lubricating oils and greases.
