2936.29.10.00 - Folic acid

This category, HTS 2936.29.10.00, specifically covers Folic Acid, also known as Vitamin B9. Folic acid is a crucial B vitamin used in a wide range of applications, most notably in preventing certain birth defects, as a treatment for anemia, and as a dietary supplement. Within the broader heading of "Provitamins and vitamins," this subcategory isolates specific vitamins and their synthesized counterparts that are not otherwise enumerated.

It is important to distinguish Folic Acid from its sibling categories. For instance, HTS 2936.29.16 covers Niacin (Vitamin B3) and Niacinamide, which have distinct chemical structures and physiological functions. Unlike those explicitly named vitamins, Folic Acid falls under the "Other vitamins and their derivatives" group, signifying it is not a specifically listed vitamin at this level but is recognized as a distinct and commercially significant vitamin entity.

As a leaf node, HTS 2936.29.10.00 does not have further subcategories. Classification at this level is typically determined by the specific identification of the chemical compound as Folic Acid, whether produced naturally or through synthesis. The primary use as a vitamin is the defining characteristic for its placement within this heading.
