9902.02.51 - 7-Hydroxycitronellal (7-Hydroxy-3,7-dimethyloctanal) (CAS No. 107-75-5) (provided for in subheading 2912.49.55)

This HTS classification, 9902.02.51, specifically covers 7-Hydroxycitronellal, also identified by its Chemical Abstracts Service (CAS) number 107-75-5. This aromatic aldehyde, scientifically known as 7-Hydroxy-3,7-dimethyloctanal, is primarily recognized for its characteristic floral scent and is a key intermediate in the fragrance and flavor industry. Its unique chemical structure and olfactory properties distinguish it from other aldehydes or alcohols that may fall under different HTS provisions.

As a provision within Chapter 99, which deals with temporary legislation and trade modifications, this specific code addresses the importation of 7-Hydroxycitronellal when subject to special import restrictions or temporary measures, often proclaimed pursuant to trade agreements or Section 22 of the Agricultural Adjustment Act. It is important to note that while this classification designates a specific chemical compound, its placement under Chapter 99 signifies that it is being regulated under a temporary provision, overriding its usual classification under Chapter 29 (Organic Chemicals) as indicated by its reference to subheading 2912.49.55.

Since this is a leaf node within the HTS structure, there are no further subcategories to explore. The classification 9902.02.51 is definitive for 7-Hydroxycitronellal when imported under the described temporary import provisions. Importers must ensure they are compliant with any specific documentation, quantity limits, or other requirements associated with this temporary classification, as it supersedes the standard tariff treatment that would otherwise apply to this chemical under its normal HTS classification.
