9902.03.41 - 2-[4-(2-Methyl-2-propanyl)phenoxy]cyclohexyl 2-propyn-1-yl sulfite (Propargite) (CAS No. 2312-35-8) (provided for in subheading 2920.90.10)

This HTS category, 9902.03.41, specifically covers the chemical compound known as Propargite, identified by CAS Number 2312-35-8. The chemical name is 2-[4-(2-Methyl-2-propanyl)phenoxy]cyclohexyl 2-propyn-1-yl sulfite. This designation falls under Chapter 99, which pertains to temporary legislation and trade agreement modifications, indicating that its classification and potential duty treatment may be subject to specific, time-limited provisions rather than permanent tariff schedules. Its primary application is as an acaricide.

Distinguishing this category from its siblings within Chapter 99 is crucial. The other entries in Chapter 99 are likely to cover various other temporary tariff adjustments, special provisions, or additional import restrictions related to different goods or trade agreements. Therefore, 9902.03.41 is unique in its specific focus on the chemical Propargite, as opposed to broader categories of temporary measures that might apply to other product classes. The parenthetical note "(provided for in subheading 2920.90.10)" is essential, as it points to the underlying permanent HTS classification for this substance, which would be used when temporary provisions do not apply.

As this is a leaf node in the HTS database, there are no further subcategories within 9902.03.41. Classification decisions at this level will hinge on the precise identification of the imported merchandise as Propargite. Importers must ensure that the goods precisely match the chemical name and CAS number to correctly apply this specific temporary classification provision. Understanding the underlying permanent classification in 2920.90.10 will be necessary for determining the correct duty rate once any applicable temporary provisions expire or are no longer in effect.
