Overview
This HTS category, 9902.02.84, specifically covers (E)-2-Butenoic acid, also known as trans-crotonic acid, identified by CAS number 107-93-7. While its primary classification is found under subheading 2916.19.30 within Chapter 29 (Organic Chemicals), this specific entry in Chapter 99 signifies a temporary modification or special provision related to its import. This means that while the substance itself is an organic chemical, its importation under this code is subject to specific, likely temporary, trade agreement legislation or Section 22 of the Agricultural Adjustment Act restrictions.
As this is a leaf node, there are no subcategories to explore. Therefore, the focus remains on understanding the distinct nature of this classification. It is crucial to recognize that 9902.02.84 is not a general classification for organic acids or even unsaturated carboxylic acids. Instead, it represents a targeted application of special customs provisions to trans-crotonic acid. When encountering this code, customs professionals should be aware that additional regulatory requirements or tariff treatments beyond its standard classification may apply due to the specific temporary legislation or agricultural adjustment provisions invoked.
