9902.06.67 - (5s,8s)-3-(2,5-Dimethylphenyl)-8-methoxy-2-oxo- 1-azaspiro[4.5]dec-3-en-4-yl ethyl carbonate (Spirotetramat) (CAS No. 203313-25-1) (provided for in subheading 2933.79.08)

This HTS category, 9902.06.67, specifically addresses "(5s,8s)-3-(2,5-Dimethylphenyl)-8-methoxy-2-oxo-1-azaspiro[4.5]dec-3-en-4-yl ethyl carbonate (Spirotetramat) (CAS No. 203313-25-1)". This is a chemical compound, identified by its precise chemical name and CAS number, which is classified for temporary legislative or additional import restriction purposes. While the parent chapter 99 broadly covers temporary legislation and import restrictions, this specific subheading zeroes in on this particular chemical.

Given the nature of Chapter 99, this subheading serves as a specific tariff line for a product that may be subject to special duties, quotas, or other trade measures outside of the standard tariff classifications found in Chapters 1-98. It is crucial to note that this subheading is explicitly linked to subheading 2933.79.08, indicating its primary classification as a heterocyclic compound containing a nitrogen atom. This distinction from other categories within Chapter 99 lies in its direct identification of a particular chemical substance rather than a broader category of goods or a general trade provision.

As this is a leaf node, there are no further subcategories within 9902.06.67. Classification under this specific subheading is definitive for the mentioned Spirotetramat, implying that any imported quantities of this compound must adhere to the conditions and regulations stipulated by its inclusion in this temporary or restricted category. The absence of subcategories reinforces the highly specific and targeted nature of this classification.
