3504.00.50.00 - Other 🖩

This HTS classification, 3504.00.50.00, encompasses "Other" peptones, their derivatives, and other protein substances not elsewhere specified or included within Chapter 35. This residual category is intended for protein-based materials that do not fit into more specific classifications, such as protein isolates (3504.00.10.00). It includes substances derived from proteins that have undergone various modifications or processing, as well as hide powder, regardless of whether it has been chromed.

Unlike protein isolates, which are typically purified proteins separated from their source material, this category captures a broader range of proteinaceous substances. For instance, it would include partially hydrolyzed proteins or complex mixtures of amino acids and peptides derived from protein breakdown, provided they are not specifically classified as isolates. Hide powder, a material used in the tanning industry, also falls under this designation due to its proteinaceous nature.

As a leaf node in the HTS structure, there are no further subcategories under 3504.00.50.00. Therefore, the classification of goods under this code relies on a thorough analysis to confirm they are indeed protein substances and their derivatives not specifically provided for in other headings or subheadings within Chapter 35. This requires careful consideration of the product's origin, manufacturing process, and intended use to distinguish it from related, more specifically defined categories.
