0910.91.00.00 - Mixtures referred to in note 1(b) to this chapter

This HTS category, 0910.91.00.00, specifically covers mixtures of spices that fall under the definition provided in Note 1(b) to Chapter 9. This note is crucial as it defines "mixtures of spices" as including products containing one or more spices where the addition of other ingredients, such as anti-caking agents or preservatives, is for the purpose of preservation or processing. Therefore, this classification applies to blended spices that might not fit neatly into single-spice categories but are still primarily considered spices by nature of their composition.

It is important to distinguish this category from its sibling, 0910.99, which is also designated for "Other spices." While both cover spices not specifically enumerated elsewhere, 0910.91.00.00 is reserved for mixtures where the primary character is that of spices, even with minor non-spice additions for preservation or processing as defined by the chapter note. Conversely, 0910.99 would generally encompass other spice preparations or single spices not otherwise classified, where the focus is not on a mixture defined by Note 1(b).

As this is a leaf node, there are no further subcategories under 0910.91.00.00. Classification within this heading relies heavily on the adherence to Note 1(b) of Chapter 9. Examples include spice blends designed for specific culinary uses that may contain small quantities of salt, sugar, or inert anti-caking agents, provided these additions do not alter the essential character of the product as a spice mixture. The determination rests on whether the added ingredients are incidental to the spice component and serve the sole purpose of maintaining the product's quality or facilitating its handling.
