2917.34.01.50 - Other

This HTS category, "Other," under esters of orthophthalic acid, encompasses a broad range of orthophthalate esters that do not fit into more specific subcategories. Orthophthalic acid esters are typically formed by the esterification of orthophthalic acid with various alcohols. These compounds are often utilized as plasticizers in polymers, contributing flexibility and durability. Their physical and chemical properties, such as boiling point, solubility, and molecular structure, are key determiners for their inclusion within this broad classification.

Distinguishing this category from its sibling, "Dibutyl orthophthalate," is crucial. Dibutyl orthophthalate is a specific, commonly encountered ester. Any orthophthalate ester that is not dibutyl orthophthalate, and is not otherwise specifically enumerated at a more detailed level, will fall under this "Other" classification. Therefore, the scope here is to capture all remaining orthophthalate esters that do not warrant a unique HTS code.

As this is a leaf node, there are no further subcategories to introduce. Classification within this category relies on a process of elimination. If a good is identified as an ester of orthophthalic acid but does not meet the criteria for any more specifically defined HTS codes within this heading, it will be classified here. This ensures that all relevant products are accounted for within the tariff schedule.
