3004.90.92.55 - Antacids

This HTS category, 3004.90.92.55, specifically covers antacids. These are pharmaceutical preparations intended for therapeutic or prophylactic use to neutralize excess stomach acid, thereby alleviating symptoms such as heartburn and indigestion. The classification applies to antacids presented in measured doses or in forms and packings suitable for retail sale.

Within the broader classification of "Medicaments primarily affecting the digestive system," this subcategory distinguishes itself from sibling categories such as laxatives (3004.90.92.50). While both address digestive system issues, antacids are designed to combat acidity, whereas laxatives are formulated to promote bowel movements. Furthermore, antacids are distinct from specific medicaments listed under subcategories like those containing famotidine or pantoprazole, which are typically proton pump inhibitors or H2 blockers that reduce acid production rather than neutralize it directly.

As a leaf node, this classification does not have further subcategories. Therefore, practical classification relies on identifying the primary therapeutic purpose of the product as an antacid. This includes preparations containing active ingredients like aluminum hydroxide, magnesium hydroxide, calcium carbonate, or simethicone, when presented in a form and packaging suitable for direct use by consumers to relieve acid-related discomfort.
