9902.06.96 - 3-{[3-(1-Aziridinyl)propanoyl]oxy}-2-({[3-(1-aziridinyl)pro- panoyl]oxy}methyl)-2-(hydroxymethyl)propyl 3-(1-aziridinyl)propanoate (CAS No. 57116-45-7) (provided for in subheading 2933.99.97)

This HTS category, 9902.06.96, specifically covers a complex chemical compound identified by the CAS No. 57116-45-7. The chemical name, 3-{[3-(1-Aziridinyl)propanoyl]oxy}-2-({[3-(1-aziridinyl)pro- panoyl]oxy}methyl)-2-(hydroxymethyl)propyl 3-(1-aziridinyl)propanoate, describes a substance with multiple aziridinyl functional groups. This classification exists within Chapter 99, which is reserved for temporary legislation and special provisions, indicating that its inclusion is for specific, likely time-limited, trade or regulatory purposes rather than standard commodity classification.

As a leaf node within Chapter 99, this category does not have subcategories. Its unique chemical structure and the specific temporary nature of its inclusion distinguish it from other entries in the HTS. While other HTS codes may describe chemical substances, this particular entry is tied to specific trade agreements or legislative actions. The "provided for in subheading 2933.99.97" notation further directs users to a more detailed classification within the standard chemical chapters, but this Chapter 99 entry signifies an overarching or special treatment applied to the substance.

The primary classification criteria for this HTS code are the precise chemical identity and its temporary designation under special trade provisions. Importers and exporters should refer to any accompanying documentation or trade notices associated with this HTS code for specific requirements, such as quotas, special duties, or licensing, which are characteristic of entries within Chapter 99. Understanding the chemical nomenclature and the legislative context is crucial for accurate classification.
