1905.31.00.21 - Containing peanuts or peanut products

This HTS category, 1905.31.00.21, specifically classifies sweet biscuits that are imported or exported in a frozen state and contain peanuts or peanut products. These goods are a subset of "Sweet biscuits" (1905.31.00) within the broader classification of "Sweet biscuits; waffles and wafers" (1905.31). The defining characteristics for this sub-classification are the presence of peanuts or peanut-derived ingredients and the frozen condition of the product.

This classification is distinguished from its sibling, 1905.31.00.29, which covers all other frozen sweet biscuits not containing peanuts or peanut products. Therefore, the key differentiator is the inclusion of peanut-based components, such as peanut butter, chopped peanuts, or peanut flour. The "Frozen" designation ensures that only goods maintained in a frozen state at the time of import or export are classified here.

As this is a leaf node within the HTS, there are no further subcategories under 1905.31.00.21. The classification is complete at this level, focusing on the specific combination of frozen sweet biscuits with peanut content. Classification under this code hinges on verifying both the frozen status of the biscuit and the explicit presence of peanuts or peanut products within its composition.
