9902.02.83 - (2E,4E)-2,4-Hexadienoic acid (Sorbic acid) (CAS No. 110-44-1) (provided for in subheading 2916.19.20)

This HTS category, 9902.02.83, covers (2E,4E)-2,4-Hexadienoic acid, commonly known as Sorbic acid, identified by CAS No. 110-44-1. While the primary classification of Sorbic acid falls under subheading 2916.19.20, this specific chapter and heading within Section XXII signify special classification provisions. These provisions are typically related to temporary legislation, modifications pursuant to trade agreements, or additional import restrictions enacted under Section 22 of the Agricultural Adjustment Act. Therefore, items classified here are not merely Sorbic acid, but Sorbic acid subject to specific, temporary trade or regulatory measures.

As a leaf node within the HTS database, this category does not have further subcategories. Its existence as a distinct entry signifies a unique regulatory status or temporary duty rate applied to Sorbic acid, separate from its standard tariff classification. This approach allows customs authorities to manage specific trade policies or address temporary market conditions without altering the broader chemical classification structure. Users should consult specific U.S. Customs and Border Protection (CBP) rulings or Federal Register notices to understand the precise conditions and duration of the special provisions applicable to this classification.
