Overview
This HTS category, 9902.07.50, specifically classifies the compound 4-(4-Methylphenyl)-4-oxobutanoic acid - 4-ethylmorpholine (2:1), identified by CAS No. 171054-89-0. This chemical substance is provided for under subheading 2934.99.90 of the HTSUS, indicating it is a heterocyclic compound not elsewhere specified. The classification within Chapter 99 signifies that it is subject to temporary legislation or special provisions, often related to trade agreements or specific import restrictions.
Unlike the primary HTS categories that classify general merchandise based on material or function (e.g., live animals in Chapter 01), this Chapter 99 entry denotes a specialized classification. Its siblings, such as those for live animals, are entirely unrelated in terms of product type and purpose. This category's existence is driven by specific trade policy or regulatory measures rather than the intrinsic nature of the goods themselves.
As a leaf node, 9902.07.50 does not have further subcategories. Its classification is definitive, and any imported quantities of this specific chemical compound must adhere to the conditions and duties associated with this particular provision. Classification relies on accurate identification of the substance and confirmation of its status under relevant trade legislation.
