2932.99.35.00 - 2-Hydroxy-3-dibenzofurancarboxylic acid

This HTS classification, 2932.99.35.00, specifically designates 2-Hydroxy-3-dibenzofurancarboxylic acid. This compound is characterized by its fused ring structure containing both furan and benzene rings, with a hydroxyl group and a carboxylic acid group attached. Its classification falls under heterocyclic compounds with oxygen hetero-atoms only, within the broader chapter of organic chemicals.

This particular entry distinguishes itself from its siblings by its precise chemical identity. For instance, while 2932.99.32.00 covers the parent structures Benzofuran and Dibenzofuran themselves, this classification is for a derivative compound with specific functional groups. Similarly, it differs from categories like 2932.99.39.00 and 2932.99.55.00, which cover other distinct benzofuran or dibenzofuran derivatives with entirely different chemical structures and functionalities. The inclusion of "Other" at this level signifies that this specific carboxylic acid derivative is not captured by the more narrowly defined sibling categories.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification purposes at this level is on the accurate identification of 2-Hydroxy-3-dibenzofurancarboxylic acid itself. Importers and exporters should rely on laboratory analysis and product specifications to confirm the presence of this exact chemical entity to ensure correct classification and compliance with customs regulations.
