9902.06.56 - 1,3,5-Triazinane-2,4,6-trione—1,3,5-triazine-2,4,6-triamine (1:1) (CAS No. 37640-57-6) (provided for in subheading 2933.69.60)

This HTS classification, 9902.06.56, pertains to a specific chemical compound: 1,3,5-Triazinane-2,4,6-trione—1,3,5-triazine-2,4,6-triamine (1:1), also identified by CAS Number 37640-57-6. This designation falls under Chapter 99, which encompasses temporary legislation and modifications. Crucially, while this is the specific classification for this substance under temporary provisions, its underlying classification for general tariff purposes is provided for in subheading 2933.69.60, which covers other heterocyclic compounds containing a nitrogen atom or atoms only.

As a leaf node within Chapter 99, this category does not have further subcategories. Its existence within Chapter 99 signifies a temporary or special duty or restriction applied to this particular chemical compound, separate from its standard tariff treatment. This means that imports of this substance will be subject to the rules and provisions outlined within Chapter 99, potentially including quotas, specific duty rates, or other regulatory requirements that deviate from those applicable to similar chemicals classified under other HTS chapters.

This classification is distinct from the broad range of sibling categories found at the root level of the HTS, such as live animals (Chapters 01). Its focus is solely on a specific chemical compound and its temporary or special import treatment. The purpose of this specific HTS code is to manage the importation of this particular substance through temporary legislation, trade agreements, or specific agricultural adjustment provisions, ensuring compliance with current trade policies and restrictions.
