9902.03.29 - 4,4’-Oxydibenzoyl chloride (CAS No. 7158-32-9) (provided for in subheading 2918.99.43)

This HTS category, 9902.03.29, specifically covers 4,4'-Oxydibenzoyl chloride, identified by CAS Number 7158-32-9. This chemical compound, a derivative of dibenzoyl chloride, falls under the purview of Chapter 99 of the Harmonized Tariff Schedule, which encompasses temporary legislation, modifications enacted through trade agreements, and specific import restrictions implemented under Section 22 of the Agricultural Adjustment Act. Its presence in this chapter signifies that its importation may be subject to special rules and limitations beyond standard tariff classifications.

Distinguishing this category from its siblings at the same hierarchical level within Chapter 99 is crucial. While other codes within Chapter 99 might address different temporary measures or specific trade agreement provisions, 9902.03.29 is precisely designated for this particular chemical. Its classification is tied to its unique chemical identity and any specific trade policies or restrictions that the U.S. government has implemented concerning its importation, as indicated by its parenthetical reference to subheading 2918.99.43, which represents its permanent classification under the chemical chapters.

As a leaf node, this category has no further subcategories. Therefore, the focus for classification within 9902.03.29 is solely on the precise identification of 4,4'-Oxydibenzoyl chloride. Importers must ensure that the product being declared precisely matches the chemical name and CAS number to comply with the temporary legislation or restrictions applied to this specific entry. Verification of any applicable quotas, licenses, or special documentation requirements associated with this HTS code is paramount.
