2917.19.10.00 - Ferrous fumarate

This HTS classification, 2917.19.10.00, specifically covers ferrous fumarate. Ferrous fumarate is an organic salt formed from fumaric acid and ferrous iron, commonly used as a dietary supplement to treat iron deficiency anemia. Its inclusion here falls under the broader category of acyclic polycarboxylic acids and their derivatives, when not specifically enumerated elsewhere.

Within the "Other" subcategory of acyclic polycarboxylic acids and their derivatives, this code distinguishes ferrous fumarate from other related compounds. While siblings may include fumaric acid itself, other specific organic acids like maleic acid, succinic acid, and malonic acid, as well as their respective derivatives, ferrous fumarate is a distinct salt of fumaric acid with a specific iron component, making its classification crucial for accurate duty assessment.

As a leaf node, this classification does not have further subdivisions. Its definitive nature means that any product meeting the description of ferrous fumarate would fall directly under this HTS code. Proper identification relies on the chemical composition and intended use of the substance, ensuring it is correctly distinguished from other fumaric acid derivatives or iron compounds.
