1901.90.10.00 - Fluid

This HTS category, 1901.90.10.00, encompasses "fluid" food preparations falling under heading 1901, specifically those that are not elsewhere specified or included. These preparations are derived from cereals, flour, starch, or malt extract, and may or may not contain cocoa or milk-based ingredients within specified limits. The key characteristic for classification under this subheading is the physical state of the product: it must be in a liquid or semi-liquid, flowable form. Examples include fluid malt extracts, liquid infant formulas (if not specifically classified elsewhere), and other fluid food preparations based on cereals or milk that do not meet the criteria for other more specific subheadings.

It is crucial to distinguish this category from its sibling, 1901.90.20.00, which covers "solid or condensed" forms. While both subheadings fall under the "Other" provisions for heading 1901, the physical state is the sole differentiating factor. If a food preparation of the types described in heading 1901 is presented in a solid, powder, granular, or condensed form (such as a paste or thick syrup), it would be classified under 1901.90.20.00, not this fluid category.

As this is a leaf node, there are no further subcategories within 1901.90.10.00. Therefore, the focus remains on correctly identifying products that fit the description of fluid preparations of heading 1901, ensuring they are not specifically provided for in other headings or more granular subheadings within Chapter 19. Classification relies heavily on the physical form and the primary composition and intended use as a food preparation.
