2306.90.01 - Other

This HTS category, 2306.90.01, encompasses "Other" solid residues derived from the extraction of vegetable or microbial fats and oils, excluding those specifically classified under headings 2304 and 2305. This means it covers a broad range of by-products after oil has been removed from various plant or microbial sources not otherwise detailed. The primary characteristic is that these are the remaining solid materials after the fat or oil extraction process, often utilized as animal feed ingredients or for other industrial purposes.

This "Other" classification serves as a residual category for oilcakes and similar solid residues that do not fall into more specific subheadings under 2306, such as those derived from cotton seeds (2306.10), linseed (2306.20), sunflower seeds (2306.30), or coconut/copra (2306.50). Its scope is defined by exclusion, capturing materials that don't fit the more granular classifications based on the specific oil-bearing seed or plant.

Within this category, further distinctions are made to provide greater specificity. The subcategories for 2306.90.01 include residues from corn (2306.90.01.20) and hemp seeds (2306.90.01.30), recognizing the distinct nature and common usage of these by-products. The existence of a further "Other" subcategory (2306.90.01.50) highlights that even within this residual classification, there are still materials not specifically enumerated, requiring careful consideration based on the source of the extracted oil and the resulting solid residue.
