3808.92.50.40 - Formulated fungicides containing any 3-iodoprop-2-yn-1-yl butylcarbamate(IPBC)

This HTS classification covers formulated fungicides specifically containing the active ingredient 3-iodoprop-2-yn-1-yl butylcarbamate, commonly known as IPBC. These products are intended for the control of fungal diseases in various applications, ranging from agricultural settings to industrial materials and consumer goods. The key defining characteristic for this subcategory is the presence of IPBC as a primary fungicidal agent within the formulation.

This category is distinguished from its sibling category, 3808.92.50.80, which encompasses all other formulated fungicides not containing IPBC. Therefore, the presence or absence of IPBC is the sole criterion for differentiating between these two classifications at this level. This precise distinction ensures accurate tariff application based on the specific chemical composition of the fungicidal product.

As this classification represents a leaf node in the HTS structure, there are no further subcategories. Classification under 3808.92.50.40 is final when a formulated fungicide is identified as containing IPBC. Examples of products that would fall under this heading include wood preservatives, paints, and coatings formulated with IPBC to prevent fungal growth, as well as agricultural fungicides where IPBC is the active ingredient. The determination relies on a direct confirmation of IPBC's inclusion in the product's declared formulation.
