2907.21.00.00 - Resorcinol and its salts

This HTS category, 2907.21.00.00, specifically covers resorcinol and its salts. Resorcinol, also known as 1,3-dihydroxybenzene, is a dihydric phenol. It is a versatile organic compound used as a chemical intermediate in the production of adhesives, resins, dyes, pharmaceuticals, and UV stabilizers. Its salts, such as disodium resorcinate, are also included within this classification when they are primarily recognized for their resorcinol-based chemical identity.

Within the broader grouping of Polyphenols; phenol-alcohols, this subcategory is distinguished by its specific chemical structure. It differs from sibling categories such as 2907.22 (Hydroquinone and its salts) and 2907.23.00.00 (4,4'-Isopropylidenediphenol or Bisphenol A), which are classified based on their distinct dihydroxybenzene arrangements and chemical properties. While all are dihydric phenols, resorcinol's 1,3-substitution pattern is the defining characteristic for classification under 2907.21.

As this HTS code is a leaf node, there are no further subcategories. Classification decisions under this heading will therefore rely on the accurate identification of resorcinol or its salts, ensuring that the substance's chemical identity and intended use are consistent with the scope of this specific classification.
