9902.06.70 - 2-(4-Chlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)hexanenitrile (myclobutanil) (CAS No. 88671-89-0) (provided for in subheading 2933.99.06)

This HTS category, 9902.06.70, is a specific temporary provision designed to cover the fungicide known as myclobutanil (CAS No. 88671-89-0). Chemically identified as 2-(4-Chlorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)hexanenitrile, this substance is a triazole fungicide commonly used in agriculture to protect crops from various fungal diseases. Its classification under Chapter 99 signifies that it is subject to temporary legislation, trade agreement modifications, or specific import restrictions under Section 22 of the Agricultural Adjustment Act.

This provision is distinct from the permanent HTS classifications found in Chapters 1-97. While myclobutanil would otherwise be classified under subheading 2933.99.06, which covers other heterocyclic compounds containing a nitrogen atom or atoms not otherwise specified, its presence in Chapter 99 indicates a deviation from standard tariff treatment. This means that importers must adhere to the specific regulations and potential duties or limitations associated with this temporary provision, rather than the general rules for chemicals.

As this is a leaf node in the HTS database, there are no further subcategories under 9902.06.70. Classification at this level is definitive. Importers will need to ensure that the specific chemical compound being imported precisely matches the description and CAS number provided, and that all associated temporary regulations under Chapter 99 are met. Any deviations from the specified chemical structure or intended use as a fungicide could necessitate re-evaluation under a different HTS chapter or subheading.
