2009.31 - Of a Brix value not exceeding 20:

This HTS category, 2009.31, specifically covers juices derived from a single citrus fruit that have a Brix value not exceeding 20. The Brix scale measures the sugar content of a liquid. Therefore, products falling under this classification are fruit juices with a relatively low sugar concentration, originating from one type of citrus fruit. Examples include pure, undiluted orange juice, grapefruit juice, or lemon juice with a Brix reading of 20 or less, and importantly, they must not contain added spirit, although they may have added sugar or other sweeteners.

This category is distinct from its sibling, 2009.39, which encompasses "Other" juices of any single citrus fruit that *exceed* a Brix value of 20. The primary differentiating factor between 2009.31 and 2009.39 is the measured sugar content as indicated by the Brix value. Goods are classified into 2009.31 if their sugar content is at or below 20 Brix, while those above this threshold are directed to 2009.39.

Within 2009.31, further subdivisions exist to specify the type of citrus fruit. The subcategory "Lime" accounts for juices exclusively derived from limes, provided they meet the Brix requirement. The "Other" subcategory is for juices of any other single citrus fruit not specifically enumerated, such as orange, grapefruit, or lemon juice, again adhering to the Brix limitation. This granular breakdown allows for precise tariff application based on the specific fruit and its sugar concentration.
