9902.07.51 - C1-C3 Perfluoroalkyl perfluoromorpholine (CAS No. 382-28-5) (provided for in subheading 2934.99.90)

This HTS classification, 9902.07.51, specifically addresses C1-C3 Perfluoroalkyl perfluoromorpholine, identified by CAS Number 382-28-5. This category is designated for a particular chemical compound possessing a perfluoroalkyl chain and a perfluoromorpholine ring structure. Its inclusion within Chapter 99 signifies that it is subject to temporary legislation or specific trade agreement provisions, overriding its standard classification under Chapter 29.

Unlike the broad range of live animals found in earlier chapters (e.g., Chapters 01), this HTS code pertains to a singular, highly specialized chemical substance. Its unique designation within Chapter 99 indicates that its import status is governed by temporary measures, which may include quotas, specific licensing requirements, or preferential tariff treatments. It is crucial to note that while chemically related compounds might be classified elsewhere in the HTS, this specific entry is reserved for the precisely defined perfluoroalkyl perfluoromorpholine.

As a leaf node within the HTS, HTS Code 9902.07.51 does not have further subcategories. Its classification is definitive and relies on the precise identification of the chemical substance based on its chemical name and CAS number. The reference to its potential classification under subheading 2934.99.90 highlights that this Chapter 99 designation represents a temporary deviation from the standard chemical classification, emphasizing the importance of adhering to the specific conditions stipulated for this entry.
