0504.00.00.40 - Other

This category, HTS Code 0504.00.00.40, encompasses animal intestines, bladders, and stomachs, excluding those of fish, that are prepared for use as sausage casings and are not of hog origin. This includes products that have undergone processing such as salting, drying, smoking, or freezing to preserve them and make them suitable for this specific application. The key criterion for inclusion here is the intended use as a casing for sausages, differentiating these items from raw or simply processed animal offal.

Distinguishing this category from its sibling, 0504.00.00.20, is straightforward. The sibling category specifically covers hog casings prepared for sausage production. Therefore, this "Other" category is for casings derived from the guts, bladders, or stomachs of animals *other than* hogs, such as sheep, cattle, or poultry, when prepared for the same purpose. The distinction lies solely in the species of animal from which the casing is derived.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification into this heading, therefore, relies on a comprehensive understanding of the parent description and the specific distinction from the hog casing sibling. Importers and exporters must ensure that the animal origin and the preparation for use as sausage casings are clearly established to correctly classify these goods.
