3503.00.40.00 - Valued 88 cents or more per kg

This HTS category, 3503.00.40.00, specifically classifies inedible gelatin and animal glue that are valued at 88 cents or more per kilogram. This encompasses a range of products derived from animal collagen, such as gelatin used in industrial applications (e.g., photographic film, paper manufacturing, adhesives) or animal glues when they meet the specified value threshold. The "inedible" designation is crucial, distinguishing these industrial or technical grade products from those intended for human consumption, which would fall under different classifications.

The primary distinguishing factor for this subcategory is its value. It is differentiated from its sibling category, 3503.00.20.00, solely by the per-kilogram price. Whereas this code applies to products valued at 88 cents or higher, the sibling code covers those valued below that threshold. This price-based distinction is a common criterion in the HTS to differentiate similar goods based on their market value and potential end-use or quality.

As this is a leaf node within the HTS structure, there are no further subcategories branching from 3503.00.40.00. Therefore, the classification process for goods falling under this code concludes at this point, with the determining factors being the product's identity as inedible gelatin or animal glue, and its value per kilogram.
