2933.49.20.00 - 5-Chloro-7-iodo-8-quinolinol (Iodo chlo rhydroxy quin); Deco quinate; Diiodo hydroxy quin; and Oxy quinoline sulfate

This HTS category, 2933.49.20.00, specifically covers a group of quinoline derivatives primarily used for their medicinal properties. The listed items, including 5-Chloro-7-iodo-8-quinolinol (also known by trade names like Iodo chlo rhydroxy quin), Deco quinate, Diiodo hydroxy quin, and Oxy quinoline sulfate, are characterized by the presence of both a quinoline ring system and specific halogen or functional group substitutions that confer biological activity. Their classification here indicates their primary role as pharmaceuticals or active pharmaceutical ingredients.

Distinguishing this category from its sibling, 2933.49.26.00 "Other," is crucial. While both fall under "Other" quinoline and isoquinoline ring-system compounds that are not further fused, this specific heading is reserved for those explicitly identified as drugs or possessing significant medicinal applications. The sibling category would encompass quinoline derivatives that do not meet the criteria for drug classification, such as those used as intermediates in other chemical syntheses, dyes, or other industrial applications.

As this is a leaf node in the HTS structure, there are no further subcategories to introduce. The classification ends with this specific code, meaning that once a product is determined to fall under the description of 5-Chloro-7-iodo-8-quinolinol, Deco quinate, Diiodo hydroxy quin, or Oxy quinoline sulfate, and its intended use is confirmed as medicinal, this is the final and most precise classification. Import and export declarations should therefore accurately identify the specific compound and its pharmaceutical purpose to ensure correct duty assessment.
