Sodium Alginate Powder from China

Sodium alginate is a polysaccharide salt from brown seaweed, used in food gelling and biotech. Though alginates have specific provisions, certain derivatives fall under HTS 3913.90.20.90 as other polysaccharides in primary powder form. This applies to modified versions not purely under alginic acid headings.
