Vitamin B12 0.1% Mannitol Adsorbate
Cyanocobalamin adsorbed onto mannitol at 0.1% concentration for improved handling in tablet compression. The mannitol acts as a carrier or excipient, and Vitamin B12 remains the principal active ingredient. This falls under tariff item 2936.26.00, as the mannitol does not render the product suitable for a specific use other than as a vitamin supplement.
