Edible Products of Animal Origin, Not Elsewhere Specified

A residual catch-all for animal-derived edible products that do not fit any more specific heading, this category (0410900000) captures items such as certain insects not covered by 041010, royal jelly, bird's nest, and other specialty animal-origin foods. Indonesia and Vietnam are the leading suppliers, reflecting the significance of bird's nest (swiftlet nest) and similar Southeast Asian specialty products in this heading. FDA governs these imports as human food, and the classification challenge is substantial — importers must confirm that no more specific HTS provision applies before defaulting to this NESOI line. The diversity of products covered means admissibility requirements vary widely by product type.
