0505.90.60.00 - Other

This category, HTS Code 0505.90.60.00, encompasses a variety of bird-related materials that have undergone cleaning, disinfection, or preservation treatments but are not further worked. It is intended for products that do not fall into more specific descriptions within Chapter 5 of the Harmonized Tariff Schedule related to animal products.

Crucially, this "Other" classification serves as a residual category. It distinguishes itself from its sibling, 0505.90.20, which specifically covers feather meal and waste. Therefore, goods classified here are not considered processed into meal or waste. Examples might include feathers or down that have been treated but are still in a relatively intact form, intended for uses other than animal feed.

As this is a leaf node, there are no further subcategories. Classification into this specific code relies on identifying bird parts with feathers or down, or feathers, parts of feathers, and down, that meet the treatment criteria but do not fit any other more specific provision within heading 0505. The key is that they are not further worked beyond the initial preservation steps and are not designated as meal or waste.
