2710.19.40.00 - Other

This category, HTS Code 2710.19.40.00, encompasses lubricating greases that do not fall under the more specific classification of greases containing not over 10 percent by weight of salts of fatty acids of animal or vegetable origin (HTS 2710.19.35.00). Lubricating greases are semi-solid to solid lubricants that consist of a base oil (typically petroleum-based) thickened with soap, non-soap thickeners, or a combination thereof. Their primary function is to reduce friction and wear between moving surfaces, particularly where a liquid oil might not stay in place or where sealing is required.

The key differentiator for this classification is the absence of significant amounts of fatty acid salts. While the parent categories cover a broad range of petroleum-derived lubricants, this subcategory specifically isolates greases with a different composition of thickening agents. For instance, greases classified under 2710.19.35.00 would contain specific quantities of animal or vegetable derived fatty acid salts, whereas the greases classified here would likely utilize mineral-based thickeners, synthetic thickeners, or other non-fatty acid based formulations.

As this is a leaf node, there are no further subdivisions under HTS 2710.19.40.00. Therefore, the classification relies solely on the physical and compositional characteristics of the grease itself, focusing on its lubricating properties and the absence of the specific fatty acid salt content that would place it in a sibling category. Importers and exporters should carefully review the composition of their lubricating greases to ensure accurate classification, paying close attention to the type and percentage of thickening agents used.
