1901.10.33.00 - Described in additional U.S. note 2 to this chapter and entered pursuant to its provisions

This HTS subcategory, 1901.10.33.00, specifically covers infant formula that contains oligosaccharides and is prepared for retail sale. These products are designed as nutritional substitutes or supplements for breast milk, tailored to meet the specific dietary needs of infants. The presence of oligosaccharides is a key defining characteristic for classification within this code.

This category is distinguished from its sibling, 1901.10.36.00 ("Other"), by the explicit requirement of containing oligosaccharides. While both fall under preparations suitable for infants and are put up for retail sale, 1901.10.33.00 is for those formulations where oligosaccharides are a specified ingredient. This specificity allows for precise tariff application based on the product's composition.

As a leaf node, 1901.10.33.00 does not have further subcategories. Therefore, the classification is determined by meeting the criteria of being infant formula containing oligosaccharides, suitable for infants, presented for retail sale, and not falling under other more specific provisions. Importers should ensure that the product's formulation, as declared on product labels and documentation, clearly indicates the presence of oligosaccharides to correctly apply this tariff heading.
