2909.50.10.00 - 4-Ethylguaiacol 🖩

This HTS category, 2909.50.10.00, specifically covers 4-Ethylguaiacol. 4-Ethylguaiacol is an organic compound that falls within the broader classification of ether-phenols and their derivatives. It is characterized by its specific chemical structure, which includes both an ether functional group and a phenol group, with an ethyl substituent attached to the guaiacol backbone. This compound is often encountered in the flavor and fragrance industries, as well as in applications related to food and beverages due to its smoky or spicy aroma.

The key distinction between this specific subcategory and its sibling, 2909.50.20.00, lies in the specificity of the chemical structure. While 2909.50.20.00 encompasses guaiacol itself and a broader range of its derivatives, 2909.50.10.00 is reserved solely for the compound 4-Ethylguaiacol. This precise delimitation is crucial for accurate customs declarations, ensuring that only goods matching the exact chemical identity of 4-Ethylguaiacol are classified here. The "Other" sibling category would encompass any remaining ether-phenols or their derivatives not specifically listed.

As 2909.50.10.00 represents a leaf node in the HTS structure, it does not have further subcategories. Classification within this code relies on the precise identification of the imported or exported substance as 4-Ethylguaiacol. Customs professionals should refer to chemical specifications, Certificates of Analysis, and other relevant documentation to confirm that the goods meet the defined chemical identity and properties of 4-Ethylguaiacol before assigning this HTS code.
