2710.19.35.00 - Containing not over 10 percent by weight of salts of fatty acids of animal (including marine animal) or vegetable origin

This HTS category, 2710.19.35.00, specifically classifies greases that contain no more than 10 percent by weight of salts of fatty acids derived from animal (including marine animal) or vegetable sources. These greases are distinguished from other lubricating greases by this precise compositional threshold. The primary purpose of these products is lubrication, typically for mechanical applications requiring a semi-solid to solid lubricant.

Within the broader classification of lubricating greases, this particular subcategory is distinct from "other" greases (2710.19.40.00). While "other" greases may have higher percentages of fatty acid salts or be formulated with different primary constituents, the focus here is on those greases where the contribution of animal or vegetable-derived fatty acid salts is deliberately limited to a minor component.

As a leaf node within the HTS, this classification does not have further subdivisions. Therefore, to correctly classify a product under 2710.19.35.00, the key determinative factor is the weight percentage of fatty acid salts of animal or vegetable origin. If a grease meets the criteria of being a lubricating grease and has 10 percent or less by weight of these specific fatty acid salts, it falls into this category. Conversely, greases exceeding this threshold for fatty acid salts would be classified elsewhere.
