2922.50.19.00 - Guaiacol derivatives

This classification, HTS Code 2922.50.19.00, specifically covers guaiacol derivatives that do not fall under the more narrowly defined drug categories within the broader group of aromatic amino-compounds with oxygen function. Guaiacol, an organic compound derived from wood smoke or synthesized, serves as a foundational structure for these derivatives. The products classified here are characterized by the presence of both an amino group and an oxygen-containing functional group attached to an aromatic ring system derived from guaiacol.

Distinguishing this category from its siblings, HTS Codes 2922.50.14.00 and 2922.50.17.00, is crucial for accurate classification. While those subcategories are designated for specific pharmaceutical applications like cardiovascular drugs or dermatological agents and local anesthetics, this residual "Other" category encompasses guaiacol derivatives intended for a wider range of uses. These might include intermediates in chemical synthesis, specialty chemicals for industrial processes, or compounds with other non-medicinal applications, provided they meet the structural criteria of being a guaiacol derivative with an amino and oxygen function on the aromatic ring.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification within 2922.50.19.00 is determined by the precise chemical structure of the guaiacol derivative and its intended use, when it does not qualify for the more specific drug classifications. Importers and exporters should consult detailed chemical specifications and intended application documentation to ensure correct entry.
