0511.99.40.40 - Other animal semen

This HTS category, 0511.99.40.40, specifically covers other animal semen that is not elsewhere specified or included within Chapter 5 of the Harmonized Tariff Schedule. This classification encompasses semen from various animal species, excluding those specifically itemized under different subheadings. The intent is to capture all animal semen that does not fit into more precise classifications based on species or intended use.

It is important to distinguish this category from its siblings. While the sibling "Cattle embryos" falls under the broader "Other" heading within 0511.99.40, it is distinct in its physical form and biological nature. Similarly, "Dried blood" (0511.99.40.30) and the even broader "Other" (0511.99.40.70) are separate classifications. This specific subheading is dedicated solely to the seminal fluid itself, prepared for artificial insemination or research purposes, and not to other reproductive materials or byproducts.

As a leaf node, 0511.99.40.40 does not have further subdivisions. Therefore, classification within this code relies on a thorough understanding of what constitutes "other animal semen" and ensuring that the product does not meet the criteria for any other HTS classification. Factors such as the species of origin, whether it is fresh, chilled, or frozen, and its intended use (e.g., for breeding programs, scientific research) are crucial for accurate classification under this subheading.
