2106.90.15.00 - Containing over 20 percent but not over 50 percent of alcohol by weight

This HTS category, 2106.90.15.00, specifically classifies compound alcoholic preparations intended for the manufacture of beverages. To fall under this heading, these preparations must contain an alcohol content by weight that is greater than 20 percent but does not exceed 50 percent. These are typically concentrated flavorings, extracts, or essences that have a significant alcoholic base, designed to be diluted or further processed into finished beverage products.

The key differentiator for this classification is its precise alcohol content. It is distinct from its sibling categories by being neither a low-alcohol preparation (not over 20 percent by weight, 2106.90.12.00) nor a high-alcohol preparation (over 50 percent by weight, 2106.90.18.00). This precise measurement of alcohol content is a critical factor for customs classification, often impacting duty rates and regulatory requirements.

As this is a leaf node in the HTS structure, there are no further subdivisions. Classification within this category is therefore determined solely by the criteria of being a compound alcoholic preparation used in beverage manufacturing and its specific alcohol content by weight, falling within the 20% to 50% range. Examples could include certain types of bitter extracts, flavored alcohol bases for liqueurs, or concentrated spirit essences.
