Ferrous Fumarate with Stabilizer
Ferrous fumarate with a minimal ascorbic acid stabilizer is a chemically defined iron(II) salt of fumaric acid, an acyclic polycarboxylic acid. The stabilizer is added for transport stability, which is permitted under Chapter 29 note (f). This product falls under tariff item 2917.19.00 as an 'Other' acyclic polycarboxylic acid derivative.
