9902.07.19 - (2E)-3-(4-Chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-(4- morpholinyl)-2-propen-1-one (CAS No. 110488-70-5) (provided for in subheading 2934.99.12)

This HTS code, 9902.07.19, falls under Chapter 99, which is reserved for temporary legislation, modifications, and specific import restrictions. Specifically, this subheading pertains to the chemical compound (2E)-3-(4-Chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-(4-morpholinyl)-2-propen-1-one, identified by CAS Number 110488-70-5. This classification indicates that the importation of this particular substance is subject to specific, often temporary, trade regulations or restrictions beyond the standard tariff classifications found in Chapters 1 through 98.

While other HTS codes within Chapter 99 may address different temporary measures or specific product categories subject to restrictions, 9902.07.19 is precisely defined by its chemical nomenclature and CAS number. This ensures that it does not overlap with broader temporary provisions or restrictions that might apply to other classes of goods. Its specificity is crucial for accurate import declaration and compliance with any proclaimed trade agreements or agricultural adjustments.

As this subheading is a leaf node, it does not have further subdivisions. Instead, the classification is entirely dependent on the identification of the chemical compound itself. Importers must ensure that the substance they are importing precisely matches the chemical description and CAS number provided. Any deviation or ambiguity in identification would necessitate reclassification under a different, more appropriate HTS code, potentially in Chapters 29 through 38 which cover organic chemicals.
