0506.90.00.20 - Bones, crude, steamed or ground

This classification covers bones that have undergone specific preliminary treatments, namely steaming or grinding, for use in various industrial or commercial applications. The "crude" designation indicates that these bones have not been significantly processed into finished articles or specialized components beyond these initial preparations. Examples include bone meal derived from steamed bones, or ground bone used as a component in fertilizers or animal feed.

This category is distinguished from other potential categories within Chapter 05 by its focus on bones that are either steamed or ground. While other bone products might exist in the HTS, this specific subheading captures those undergoing these particular preparatory steps, signifying a level of processing that prepares them for further industrial use but does not constitute a finished product.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus for classification here is on ensuring the goods meet the description of being "bones, crude, steamed or ground" and are not otherwise specifically classified under a more detailed provision. Classification relies on the physical state and the specific preparatory process (steaming or grinding) that has been applied.
