2103.90.90.51 - In containers holding less than 1.4 kg

This HTS classification, 2103.90.90.51, specifically covers tomato-based preparations for sauces when they are packaged in containers holding less than 1.4 kg. These preparations are typically used as condiments or seasoning agents and form a significant component of sauces due to their tomato base. Examples include concentrated tomato pastes, purees, or sauces that are specifically formulated for use in creating other sauces or as a direct sauce component, provided they meet the weight limitation per container.

This category is distinguished from its sibling, 2103.90.90.59, by the critical criterion of container weight. While both fall under the broader "Other" subcategories of "Sauces and preparations therefore," 2103.90.90.51 is exclusively for those packaged in smaller containers (under 1.4 kg), whereas 2103.90.90.59 encompasses similar tomato-based preparations in larger packaging. This weight distinction is a primary factor in ensuring accurate tariff application.

As this classification node is a leaf node, there are no further subcategories. Therefore, the focus remains on the precise definition and distinguishing characteristics of tomato-based preparations for sauces, specifically emphasizing the container weight limit of less than 1.4 kg as the defining feature for this particular HTS code. Classification decisions within this code should prioritize the tomato content, the preparation's function as a sauce base or component, and the specified packaging size.
